Description

It relates to direct current management and electric hot water supply by solar power generation.

FIG. 1 is an example of a schematic diagram of an existing solar power generation system (Non-Patent Document 1). The direct current indicated by the solid line arrow from the solar battery (101) is concentrated on the connection box (102) and then converted into the alternating current indicated by the dotted line arrow having a voltage slightly higher than the lamp line voltage by the AC converter (103). The total amount of AC generated from the solar battery (101) is converted to DC through the AC distribution board (104) and converted into DC by the converter (105) built in or placed in the AC power source household electrical device (106). The AC power is consumed by the home electric device (106). The AC power supply household electric appliance (106) that uses a lot of DC-driven semiconductors in recent years requires a converter (105). For example, a personal computer obtains a direct current through a converter (105), and performs Internet information exchange, Internet television viewing, and various calculations. Since current commercial electricity is carried by alternating current, electrical products appear to be powered by an alternating current power supply, but in reality, many of the products are operated after the alternating current power supply is first turned into direct current.
The surplus that cannot be consumed is passed through the reverse flow prevention wattmeter (56) that has passed the measurement test that rotates only when the current flows toward the power line, and then the current flows into the house. Electric power is supplied to the electric power company as a reverse power flow through a non-reverse demand integrated power meter (57) that has passed a measurement test that does not rotate when flowing. The electric power flowing from the power line to the AC power supply household electric appliance (106) is measured by the reverse rotation prevention demand integrating wattmeter (57) and sold to the home at the same selling price as before. The power flowing in the power line due to the reverse power flow is not measured by the reverse rotation preventive demand integrating wattmeter (57).
The electric power flowing from the home to the power line as a reverse power flow is measured by a reverse flow preventive reverse flow integrating wattmeter (56), and the power sales company purchases the reverse power flow at a price about twice the sales price.
The electric power consumed from the solar battery (101) to the AC power source household electrical device (106) via the AC distribution board (104) is free.
AC power supply Home electric appliance (106) is consumed free of electricity, solar battery (101), junction box (102), AC converter (103), AC distribution board (104), prevention of reverse rotation Cannot amortize the installation cost of integrated wattmeters with equipment. It is not enough to have the reverse power flow purchased at twice the selling price. Therefore, a subsidy is attached from the government when the current solar power generation system is installed.
Hot water supply accounts for a relatively high percentage of household energy consumption. Hot water passes from the electric water heater (204) to the water tap (201) through the horizontal tap neck (202) through the hot water pipe (205). If the water tap (203) is closed and water is not supplied, water has been removed from the horizontal faucet neck (202) and air has accumulated. It takes a long time to open hot water at the tap (201) after opening the open / close tap (203), and it takes some time, and cold water comes out first.
FIG. 2 is an overview of loads in a factory or the like that uses commercial AC power as power. To control and drive the motor, AC power, which is a commercial power supply, is converted to direct current by a converter unit built in the inverter device, and then the direct current is converted into a wide range of high-frequency alternating currents relatively freely by transistors in the inverter unit built in the inverter device. And convert AC voltage widely with a transformer to adjust motor drive relatively freely. In addition, what put together the converter part and the inverter part is generally called the inverter apparatus. The inverter device is a kind of power supply device that stably controls rotation without selecting an induction motor to be driven. Inverter devices, motor-consumed home appliances such as air conditioners, are also built into high-end fluorescent lamps.

I want to thoroughly control the generation of carbon dioxide, which is considered the cause of global warming. One solution to global environmental problems is to install solar power generators on the roofs of individual households instead of AC power generation by fossil fuel combustion that emits carbon dioxide gas, convert solar energy into DC electricity, and further supply AC power In order to be able to use most household electrical appliances that have specifications, the direct current from the photovoltaic power generation device is converted into alternating current and then consumed by the household electrical appliances of the household AC specification. Surplus AC power is returned to commercial AC power. Most home appliances with AC power supply specifications that presuppose the use of commercial AC power (for example, in an air conditioner, convert the AC power to DC with an inverter and then convert it to an appropriate AC again to freely adjust the motor speed. Power loss occurs in conversion from AC power to DC.
Thus, in order to convert direct current into alternating current, additional equipment costs such as an alternating current converter (103) are required, and in order to return surplus alternating current power to a commercial alternating current power supply, a reverse flow preventing reverse flow integrating wattmeter (56) The cost of electricity is very high because of the additional equipment costs.
Conventional use of solar energy can only be realized by high-priced power purchase regulations that are widely and thinly imposed on ordinary households through subsidies from the country and power companies. For consumers, there is no way to distinguish between electricity from sunlight and electricity from fossil fuel combustion, so it is difficult to convince the big difference in electricity charges. I don't think it will last long.
That said, we want to curb the use of fossil fuels that generate carbon dioxide to solve global environmental problems. Furthermore, if fossil fuels (oil and natural gas), which are important for the Japanese economy, cannot be imported, the country's fundamental technology collapse crisis may occur. Therefore, it is necessary to devise another way of using solar energy. In other words, is there a problem with the method of installing a photovoltaic power generation device on the roof of a private home and converting it to alternating current?
On the other hand, is there any problem in how to use electricity? For example, is there a problem with hot water supply that accounts for a relatively high percentage of household energy consumption? It takes some time for the hot water to come out of the tap (201) after opening the open / close tap (203). Electricity in the electric water heater (204) until hot water actually comes out seems to be useless. In hot water supply in a bath or a kitchen, hot water does not come out immediately even if the faucet is opened, and cold water is initially used. Even with a hand wash, if you open the faucet, gas combustion will end before hot water comes out. Even after the use is finished, warm water remains in the hot water supply pipe (205), but it is naturally cooled, so that energy consumption is wasted. The energy leaked from the electric water heater (204) through the hot water pipe (205) to the water tap (201) is not only foolish but also contributes to global warming.
A battery-powered automobile (100) becomes important as an electric appliance in the home that contributes to the reduction of carbon dioxide emission. Therefore, the battery-powered automobile (100) is important as a domestic electric device that contributes to the reduction of carbon dioxide emission.

Without converting direct current electricity generated from solar energy into solar cells into alternating current, home appliances in the home are used as direct current power specifications and direct current is used as it is.
It is ridiculous to install solar cells on residential roofs in large areas with low land costs, and houses in areas with high land costs are dense, so even if solar cells are installed on the roofs, they can be shaded and effective There is no. Therefore, instead of installing solar power generation facilities in each individual's home, from the closed solar power plant (2) that installed solar power generation facilities in a wide open space such as an unused industrial park in a closed area, Each household around the closed solar power plant (2) purchases DC electricity.
In addition, a large amount of power is not sold to an electric power company until an extra facility such as a reverse flow preventing reverse flow integrating wattmeter (56) is installed. For direct current electricity at night, etc., AC electricity from electric power companies is converted into direct current, and the direct current electricity is purchased. The shortage will be compensated mainly by solar power generation with AC from power company lines.
The direct current generated by the closed solar power plant (2) is supplied to the DC power source using place (20) or the battery powered vehicle (100) of a household in the closed region by the closed DC power line (3).
The power supply and demand is automatically eased by the low voltage storage battery (6) laid on the closed DC wire (3). The voltage sent from the voltmeter (11) installed in the closed DC power line (3) is read into the closed power management PHS portable computer (10) and measured and monitored. Closed area power management The power supply in the closed area is managed by a calculation program built into the PHS portable computer (10).
If the computer determines that the DC power supply is insufficient, after reducing the power generation reduction that was imposed on the solar power generation reduction facility (12) that can be installed in the closed solar power plant (2), The AC power is purchased from the existing AC power line (1) and the DC supply amount is increased by the AC / DC converter (5) with a metered wattmeter to increase the power supply to the closed DC power line (3).
If the computer determines that the DC power supply is excessive, the AC power received from the existing AC power line (1) is reduced and the DC power supply is reduced by the AC / DC converter with metered power meter (5). The power generation amount reduction imposed on the power generation reduction facility (12) is further strengthened, the power generation amount of the closed solar power plant (2) is reduced, and the power supply to the closed DC power line (3) is reduced.
If the computer determines that the emergency DC supply power is insufficient, it receives reverse power flow from the battery-powered vehicle (100) via the PHS portable control metered DC bidirectional power meter (31).
The closed area solar power generation management system that manages the power supply in the closed area as described above effectively uses sunlight to reduce the electricity charge.
In addition, as the field owners receive rents and let the electric power company build a transmission line tower, they rent a part of the garden of each household to the closed solar power plant (2) and allow solar power generation You can also
In north slopes, valleys, and heavy rain areas that are not suitable for photovoltaic power generation, messy alternating current generated by rotating the windmill is converted to direct current and stabilized via a storage battery before being transmitted to the closed direct current electric wire (3). Since solar power generation has weak points in long-term cold waves and long-term rain, it would be effective to install wind power generation as an auxiliary power source in the closed solar power plant (2) to make up for the weak points.
The best mix of solar power, wind power, self-propelled storage battery-powered automobiles (100), and existing AC power lines (1) for AC power purchase and reception would be realistic.
Carbon dioxide suppression contributes not only to the power generation side but also to power saving on the power consumption side. Saving electricity by improving the hot water supply system with high power consumption as follows contributes to the suppression of carbon dioxide.
The far-infrared laser generator (300) receives a signal from the weak signal line (303) simultaneously with the temperature control operation of the temperature control / open / close switch (207) which integrates the functions of the water tap (203) and the temperature control lever (206). ). The generated far-infrared laser is guided by an optical cable (302) to a laser irradiation port (301) laid on the upward faucet neck tube (208). By irradiating the far-infrared laser to the water in the upward faucet neck tube (208), the temperature of the water is started. Water supply and the far-infrared laser generator (300) start a continuous operation by a water supply operation of the temperature adjustment / opening / closing plug (207) with a slight time delay from the temperature adjustment operation of the temperature adjustment / opening / closing plug (207). The far-infrared laser generator (300) is stopped by a signal from the weak signal line (303) at the same time as the temperature control and opening / closing plug (207) is closed. This is the far infrared laser hot water supply system of the present invention. Far infrared rays are suitable for increasing the water temperature because they are easily absorbed by water.
This is a far-infrared laser cooking system in which a far-infrared laser generated by operating a far-infrared laser generator (300) is guided into a bath tub by an optical cable (302) to cook hot water in the bath. Since the bath water temperature can be raised without increasing the amount of water, water resources can be saved and power can be saved. In the method of adding hot water in order to raise the bath water temperature, the hot water in the bathtub where hot water is stretched up to the upper surface is discarded. It will be useless.
In the present invention, the amount of warm water is the minimum necessary amount of water in the upward faucet neck tube (208) portion, thus saving energy. Furthermore, since direct current electricity is converted into an infrared laser and then sent to the faucet, the user can be prevented from receiving an electric shock.
The far-infrared laser generator (300) may be installed outdoors.
The far-infrared laser hot-water supply system and far-infrared laser reheating system of the present invention are effectively operated by an inverter device even when an AC lamp line is used as a power source.
As the closed solar power plant (2), only the solar power generation facilities installed in the gardens and roofs of neighboring households can be used. In each individual house, a solar cell installation, a storage battery driven automobile (100) (also referred to as a self-propelled storage battery), and a commercial AC to DC converter installation become a DC-utilized home.
That is, the direct current from the solar battery (101) is concentrated in the junction box (102) to increase the voltage and pass through the vehicle replacement storage battery (402), and the reverse rotation prevention demand integrating wattmeter (57) or the current demand. A commercial AC drawn into the house via a quantity integrating wattmeter (currently installed AC power meter currently installed in a home) is a voltage lower than the rated voltage of the replacement storage battery for vehicles (402) by the AC / DC converter (401) The direct current converted into the direct current is collected in the DC distribution board (112) in the house, and the DC resistor (113) extends from the DC distribution board (112) to the main part in the house. In 122), a DC solar power generation system in which the DC power supply household electric appliance (121) is operated by adjusting to an appropriate current and voltage is obtained.
The battery-powered vehicle (100) uses three vehicle replacement storage batteries (402) as a drive source, replaces the vehicle replacement storage battery (402) by three batch replacement, and reserves the vehicle replacement storage battery for charging. A three-batch exchange battery powered vehicle (100) with (402) is preferred.

The closed-area photovoltaic power generation management system and far-infrared laser reheating system of the present invention based on the premise that the direct current generated by solar power generation is consumed as it is without being converted into alternating current. Since there is no double conversion loss of converting direct current to alternating current and converting the alternating current to direct current to consume electricity, it is possible to improve the efficiency of electricity use and reduce the equipment cost by simplifying the electrical equipment.
Since there is no need to purchase expensive reverse flow power, the reverse flow prevention reverse flow integrating wattmeter (56) is not required, and the installation cost is reduced.
The government will be safer on energy resources, and power companies will no longer need to purchase expensive reverse power, so the subsidy for installing a closed solar power management system will be borne by both parties.
Unused industrial parks that are burdened by local governments and countries are everywhere. There is no inconvenience to get a part of it as a subsidy.
Establishing a closed solar power management system will increase the number of employees, residents, and corporations, so tax revenue will be obtained both directly and indirectly.
In particular, the closed solar power management system is ideal for the Self-Defense Forces that require the maintenance of self-contained functions. The Self-Defense Forces, whose main purpose is to protect the public, will not be indifferent to global warming, and it cannot be limited to training and self-defense actions just because of rising oil prices and lack of oil. It is ideal for laying solar power generators in the space near the shooting range and the large garrison. Electric military vehicles (not including heavy self-propelled guns and rocket guns), communication devices, etc. Can cover much of self-consumption energy. If you are worried about bad weather, you can reinforce the storage battery or have a portable small nuclear reactor. Unlike alternating current, direct current can be stored in storage batteries and capacitors.
Since the far-infrared laser hot water supply system of the present invention has a large energy saving effect, the capacity of the photovoltaic power generation facility can be reduced, and the cost can be reduced. Furthermore, an electric shock accident can be reduced.
Since it is easy to supply hot water using electricity, the generation of carbon dioxide and carbon is inevitable, and normal consumption due to the use of natural gas and excessive hydrogen fuel will be reduced.

  By using the direct current generated by solar power generation as it is without converting it into alternating current, the efficiency of electricity use was improved.

FIG. 3 is an overview of the closed solar power management system of the present invention. In Japan, there are vast unused vacant lots such as unused industrial park land and reduced fallow fields. The area around this unused space is considered a closed area. A solar cell is installed in this closed area to generate DC power to form a closed solar power plant (2), and direct current is fed from the terminal (7) to the closed DC power line (3) that is stretched only in this closed area.
DC power stations (20), such as houses and factories in closed areas, purchase direct current via a PHS portable built-in metered DC wattmeter (21) with a built-in PHS mobile terminal, and the amount of power used is closed power from the PHS mobile terminal. It is transmitted to the management PHS portable built-in computer (10). The computer deducts the electricity bill from each person's bank account at the end of the month.
A battery-powered vehicle (100) such as an electric vehicle or a hybrid vehicle trades DC with a prepaid card or a watermelon card each time via a PHS portable control metered bidirectional DC power meter (31) incorporating a PHS portable terminal. In the case of reverse power flow from the battery-powered vehicle (100) to the closed DC power line (3), the balance of the prepaid card inserted into the PHS portable control metered bidirectional DC power meter (31) is increased.
A low voltage storage battery (6) set to a voltage lower than the voltage flowing through the closed DC power line (3) is laid on the closed DC power cable (3) to automatically relieve power supply and demand. If the voltage which flows into a closed region DC electric wire (3) falls, it will discharge to the closed region DC electric wire (3) side from a low voltage storage battery (6). Conversely, if the voltage flowing through the closed DC power line (3) increases, direct current flows from the closed DC power line (3) side to the low voltage storage battery (6) side and is stored.
A voltmeter (11) is laid on the closed DC wire (3) to constantly measure the voltage. In order to manage the power supply only in the closed area, the closed-area power management PHS portable computer (10) incorporating the PHS mobile reads the measured value from the voltmeter (11), and measures and monitors the DC power supply. Closed area power management The power supply in the closed area is managed by a calculation program built into the PHS portable computer (10).
If the computer determines that the DC power supply is insufficient, after reducing the amount of power generation imposed on the solar power generation reduction facility (12) installed in the closed solar power plant (2) and increasing the amount of solar power generation Then, AC power is purchased from the existing AC power line (1), and the DC supply amount is increased by the AC / DC converter (5) with a metered wattmeter to increase the power supply to the closed DC power line (3).
If the computer determines that the DC power supply is excessive, the AC power received from the existing AC power line (1) is reduced and the DC power supply is reduced by the AC / DC converter with metered power meter (5). The power generation amount reduction imposed on the photovoltaic power generation reduction facility (12) is further strengthened, the power generation amount of the closed solar power plant (2) is reduced, and the power supply to the closed DC power line (3) is reduced.
When the computer determines that the emergency DC supply power is insufficient, the computer receives reverse power flow from the battery-powered vehicle (100) via the PHS portable control metered DC bidirectional power meter (31).
As the photovoltaic power generation reduction facility (12), an electric light shielding curtain or a disconnection switch in a photovoltaic cell group connection circuit can be considered.
When there is a shortage of electric power, it can be replenished from the existing AC power line (1), so each house or factory does not have to install a storage battery individually, so the overall cost is reduced.
When there is a surplus in the amount of photovoltaic power generated, the photovoltaic cells may be shielded from light, or the switches in the photovoltaic cell group connection circuit may be disconnected.
In the spring and autumn seasons when demand is low, the amount of photovoltaic power generation can be reduced by inspection of some facilities. Solar energy is free and will not cause major damage. In addition, as for the electric power of the existing alternating current system electric wire (1), it is desirable that the thing from the nuclear power generation which does not discharge | release carbon dioxide gas is mainly from the meaning of this invention.
The capacity of the low voltage storage battery (6) is effective as a stabilized power source if there is a storage capacity of about 30 minutes of local power demand.
FIGS. 4-1 and FIGS. 4-2 are flowchart examples of calculation programs built in the closed power management PHS portable built-in computer (10).
Step 0: The initial setting value is read into the computer.
Built-in constant DC voltage V0.
Built-in allowable DC voltage error dV0. If the DC voltage is in the range of V0-dV0 to V0 + dV0, it is considered that the demand and supply of power are balanced.
The fluctuation range dS of the reduction ratio ss (t) of the photovoltaic power generation reduction facility (12) is incorporated.
It incorporates the fluctuation range dD of the DC current ID (t) flowing out to the closed DC wire (3) through the AC / DC converter with metered power meter (5) and the allowable value IDmax of the current ID (t).
Step 1: The electric state at time t is constantly read into the computer.
The DC voltage V (t) value flowing through the closed DC power line (3) is read from the voltmeter (11).
Receives power from the existing AC power line (1) and reads the DC current ID (t) value flowing through the AC / DC converter with metered wattmeter (5) and flowing into the closed DC power line (3).
The reduction ratio ss (t) value of the photovoltaic power generation reduction facility (12) is read.
Set up the electricity bill at the end of the month. The power consumption value is calculated from the previous month's value and current month's value of the PHS portable built-in DC power meter (21), and a procedure for transferring charges from the registered bank account to the bank account of this system is instructed. The PHS portable control metered DC bidirectional ammeter (31) starts operating when a prepaid card is inserted, and the power used is settled by the prepaid card.
Step 2: If the difference between the voltage V (t) at the time t and the set value V0 is within the error dV0, go to Step 3. If it is out of range, go to step 5.
Step 3: If there is no DC current ID (t) flowing through the AC / DC converter with metered wattmeter (5) and flowing into the closed DC wire (3), the current state is maintained and the procedure goes to Step 1. If there is ID (t), go to Step 4 to reduce the amount of power received and reduce the power purchase.
Step 4: A command to increase the amount of photovoltaic power generation by reducing the reduction rate ss (t) by dS to the photovoltaic power generation reduction facility (12) of the closed area photovoltaic power plant (2) and AC / DC conversion with a metered wattmeter Command to reduce the DC current ID (t) flowing out to the closed DC wire (3) through the device (5) by dD.
This operation is continued until ss (t) becomes zero and cannot be reduced.
Step 5: If the voltage V (t) at time t is lower than the set value V0 by dV0 or more, it is determined that the power supply is insufficient, and the process goes to Step 6. If the voltage V (t) is higher than the set value V0 by dV0 or more, it is determined that the power supply is excessive, and the process goes to Step 8.
Step 6: Since power supply is insufficient, the reduction rate ss (t) is reduced by dS to increase photovoltaic power generation. Continue until you can't reduce it. Even if there is no reduction, if the power supply is insufficient, go to Step 7 to buy AC and convert it to DC.
Step 7: The DC current ID (t) flowing out to the closed DC wire (3) through the AC / DC converter (5) with a metered wattmeter is increased by dD. If ID (t) exceeds the allowable value IDmax, the AC purchase increase is stopped. A command is sent to the PHS portable control metered direct current bidirectional power meter (31) by keyboard operation, and electricity is received from the connected battery-powered vehicle (100) by reverse power flow.
If the situation still does not stop, the closed area solar power plant (2) will be stopped.
Step 8: Since the voltage V (t) is higher than the set value V0 by dV0 or more, and the power supply is excessive, go to Step 9 to reduce AC power reception.
Step 9: The DC current ID (t) flowing out to the closed DC wire (3) through the AC / DC converter with metered power meter (5) is reduced by dD. Continue until ID (t) reaches zero. When ID (t) reaches zero,
Go to step 10 in order to increase the reduction ratio ss (t) of the solar power generation reduction facility (12).
Step 10: Issue a command to reduce the amount of photovoltaic power generation by increasing the reduction ratio ss (t) by dS to the photovoltaic power generation reduction facility (12). Continue as far as possible. If the power supply is excessive even if the solar power generation is deleted as much as possible by shading as much as possible, the closed area solar power plant (2) is stopped by keyboard operation because there is a possibility of an accident.

The house of the DC power source use place (20) must be an energy-saving house using DC as a power source.
FIG. 5 shows an example of a residence at a DC power supply station (20).
The solar battery (101), the AC converter (103), and the reverse flow prevention reverse power flow integrating wattmeter (56) are not installed in the house of the DC power source use place (20). DC power is supplied from the closed DC wire (3). DC power is supplied to the house through a PHS portable built-in metered DC wattmeter (21) which is a metered wattmeter with a built-in PHS portable. Direct current is fed from the direct current distribution board (112) to the direct current electric wires (113) to the main places of the house, and each direct current power source household electric appliance (121) is appropriately connected from the direct current wires (113) through the direct current resistors (122). Use it with the correct current and voltage. The conventional AC power source household electric appliance (106) converts AC to DC through the converter (105), but this is not necessary and conversion loss is reduced, thus saving power.
Information can be exchanged wirelessly via PHS without laying a communication optical cable, which is convenient and inexpensive. Even television can be seen on the Internet.
A hot water supply system that consumes a large amount of energy at home is a far infrared laser hot water supply system.
The signal from the weak signal line (303) is simultaneously transmitted to the far-infrared laser generator (300) at the same time as the temperature control operation of the temperature control and switch (207) integrating the functions of the water tap (203) and the temperature control lever (206). ) And the generated far-infrared laser is guided by an optical cable (302) to a laser irradiation port (301) laid on the upward faucet neck tube (208), and the far-infrared laser is guided to the upward faucet neck tube (208) portion. The temperature of the water is increased by irradiating the water. The upward faucet neck pipe (208) is a pipe through which water immediately before the water tap (201) passes, and when the water supply is stopped by tilting upward toward the water tap (201), Stays on.
It is also effective to lay a human body sensor in the vicinity of the water tap (201). When a person stands in front of the water faucet (201), the far-infrared laser generator (300) is activated to raise the temperature of the water in the upward faucet neck tube (208).
Slightly delayed from the temperature control operation of the temperature control / opening / closing plug (207) (for example, the far-infrared laser generator (300) is activated for a few seconds by pulling up the lever, and then automatically stops after that) Water supply and far-infrared laser by the temperature control / opening / closing plug (207) (for example, when the lever is turned to the right, the far infrared laser generator (300) operation continuous signal starts. When the lever is turned to the left, only cold water is used). The generator (300) is activated. Hot water can be obtained from the water tap (201) in a short time.
The far-infrared laser generator (300) is stopped by a signal from the weak signal line (303) at the same time as the temperature control and opening / closing plug (207) is closed. The hot water in the upward faucet neck (208) remains there for a while and remains warm for the next use.
Thus, since the amount of hot water is the minimum necessary, energy is saved. Furthermore, since direct current electricity is converted into an infrared laser and sent to the faucet, an electric shock can be prevented.
This is a far-infrared laser cooking system in which a far-infrared laser generated by operating a far-infrared laser generator (300) is guided into a bath tub by an optical cable (302) to cook hot water in the bath. Since the bath water temperature can be raised without increasing the amount of water, water resources can be saved and power can be saved. In the method of adding hot water in order to raise the bath water temperature, the hot water in the bathtub where hot water is stretched up to the upper surface is discarded. It will be useless.

The far-infrared laser generator (300) may be installed outdoors.
The far-infrared laser hot water supply system of the present invention operates effectively by an inverter device even when an AC lamp line is used as a power source.
The factory of the DC power source use place (20) must also be a factory using DC as a power source.
FIG. 6 shows an example of a factory load at the DC power supply station (20).
The direct current supplied from the closed DC power line (3) is converted into the voltage and frequency necessary for the motor and the load machine by the inverter unit device in which the converter unit is omitted from the conventional inverter device. Since the conventional part for converting from commercial AC to DC is eliminated, the apparatus is not only simplified and cheaper, but also the loss caused when converting from AC to DC is eliminated and a power saving effect is obtained.

FIG. 7 is a schematic view of a DC solar power generation system of the present invention. In the figure, the solid line indicates direct current, and the dotted line indicates alternating current. The direct current from the solar battery (101) is concentrated on the junction box (102) to increase the voltage, and then drawn into the DC distribution board (112) in the house through the connected replacement battery for the vehicle (402).
On the other hand, commercial AC that is drawn into the house via the reverse rotation prevention demand integrating wattmeter (57) and purchased and received is converted into DC by the AC / DC converter (401) and drawn into the DC distribution board (112) in the house. The DC voltage obtained by converting commercial AC into DC by the AC / DC converter (401) is lower than the rated voltage of the replacement battery for vehicles (402). The direct current via the direct current wire (113) extended from the direct current distribution board (112) and routed to the main part of the house is adjusted to an appropriate current and voltage by the direct current resistor (122), and the direct current power source household electrical equipment ( 121) operating a direct current solar power generation system.
The battery-powered automobile (100) is equipped with a plurality of vehicle replacement storage batteries (402), and a spare part of the vehicle replacement storage battery (402) discharged during the storage battery-driven automobile (100) travel has been charged in advance. To replace the vehicle replacement storage battery (402). For example, if a battery-powered vehicle (100) that runs with three replacement batteries (402) for a vehicle travels for one day, the replacement battery (402) for one used vehicle is charged as a spare on the next day. To replace the vehicle replacement storage battery (402). A battery-powered vehicle (100) is driven in three batches. The charging time of the battery-powered automobile (100) can be shortened.
The voltage obtained by concentrating the direct current from the solar battery (101) in the junction box (102) is higher than the rated voltage of the replacement battery for a vehicle (402), and the direct current is converted from direct current to direct current by the AC / DC converter (401). The voltage is set lower than the rated voltage of the replacement battery for vehicles (402). When a shortage of power supply occurs in the DC distribution board (112), the battery replacement storage battery (402) being connected is discharged. When the power consumption in the DC power supply household appliance (121) is large and the connected replacement battery (402) for the car is sufficiently discharged and falls below the rated voltage, the commercial AC is converted to DC by the AC / DC converter (401). The replacement battery for vehicles (402) is charged with the converted direct current. The excessive power supply by the solar battery (101) is stored in the connected replacement battery for a vehicle (402).
The commercial AC power that is drawn into the house and purchased and received is measured by the reverse-rotation-preventing demand integrating power meter (57) and sold to the home at the same selling price as before.
The electric power consumed from the solar cell (101) through the DC distribution board (112) to the DC power supply household electric appliance (105) is free.

The company will first invite DC factories and telecommunications companies to the DC Industrial Park, and then build DC homes for families and shops.
While maintaining the satisfaction of healthy people and youth, a gradual bubble is necessary for the enhancement of welfare for non-healthy people and the elderly. Although the IT bubble due to the use of weak DC is over, it is thought that the present invention will newly create a DC power bubble due to the use of strong DC.
AC power generation using petroleum with poor price stability and AC home appliance society are becoming saturated. Scraping the existing AC prime mover from the factory and introducing a new direct current prime mover can improve production efficiency.
Now that fossil fuels and power generation facilities are available, there is an opportunity to switch to a solar power generation DC society. The cost of installing solar facilities is low, and until the initial investment cost is depreciated, it can be compensated with the current cheap fossil fuel power generation.
By stepping into the DC society, AC-related equipment (generators, prime movers, home appliances, and AC-related equipment manufacturing machines) will be discarded, and new demand will be created by the introduction of DC-related equipment.
Solar power generation, which is an unstable surface energy, requires the backup of nuclear power generation that does not generate carbon dioxide gas, because it cannot escape the risk of bad weather. Nuclear power generation load leveling can be achieved simultaneously.
The rooftop / site of the rest thermal power plant and surplus fuel tank may be a regional solar power plant. The dormant thermal power plant and surplus fuel tank do not need to be removed until they are expensive. Leave room to resume when something is needed.
Although it is cheap to use, the fuel tank is permanently installed at home, so it is afraid of a catastrophe and emits some carbon dioxide. In that respect, sunlight is highly safe.
The place that was strong against the construction of the nuclear power plant will be avoided because it will interfere with the future operation of the nuclear power plant (it will be misunderstood that solar power generation will come if the nuclear power plant is opposed to the nuclear power plant). It is possible to install a photovoltaic power generator in Compared to nuclear power plants, solar power generation will be introduced quickly and in large quantities so that local organizations can quickly respond to solar power generation without local countermeasure costs (electricity companies receive subsidies for controlling global warming). Let's go.
Like vending machines, there will be a business that installs solar power generators in urban gaps.
