    Pavan M. Mali presented a seminar on solar power satellites at the Bhujbal Knowledge City MET Institute of Engineering. Solar power satellites would collect solar energy via large antennas in space and transmit it to receiving antennas (rectennas) on Earth in the form of microwave beams. This would provide a clean, large-scale source of stable electric power to address issues like global warming. Key aspects discussed included the design of the transmitting antennas (spacetennas) in space and receiving rectennas on Earth, as well as prior research on wireless power transmission via solar power satellites.

    Introduction
    ➢ The exponential increase in population has led to the global crisis
    such as global warming,environmental pollution and rapid decrease of
    fossil reservoirs.
    ➢ The new millennium has introduced increased pressure for finding
    new renewable energy sources.
    ➢ Building a power sration in space to transmit electricity to earth by
    way of radio waves.
    ➢ Solar power satellites convert solar energy into electrical energy and
    then to microwaves and send them as a beam to a receiving antenna
    on the earth for conversion to ordinary electricity.
    ➢ Solar power satellite is a clean, large-scale, stable electric power
    source

    SPACETENNA:[THE ANTENNA ON SATELLITE]
    ➢ An Antenna is an electrical device which
    converts electric power into radio waves.
    ➢ The transmitting antenna on the horizontal
    under surface faces the Earth and the other two
    sides of the prism carry solar arrays.
    ➢ The microwave produced are travels through
    atmosphere and is collected by RECTENNAS on
    Earth.
    ➢ The Spacetenna has a square shape whose
    dimension is 2.4×2.5km and which is regularly
    filled with 1936 segments of sub array.
    ➢ There will be about 2.6 million antenna

    RECTENNA
    ➢ An antenna comprising a
    mesh of dipoles and diodes
    for absorbing microwave
    energy from a transmitter
    and converting it into
    electrical power.
    ➢ Microwaves are received with
    about 85% efficiency and
    95% beam will fall on the
    Rectenna.
