4. INTRODUCTION :
 Wireless power transmission (WPT),is an underdeveloped field of study.
 There are many promising applications for the ability to transport over great distances
without any need for transmission limits.
 There are some efforts made to develop new technology, that would accommodate
propagation by electronic-magnetic waves in and around the visible spectrum.
 However these technologies are just emerging.
 Solar Power satellite (SPS) generate power via microwave beam to the receiving rectenna
site on the earth.

5.  We can in fact convert solar energy to electrical energy with the use of solar cells, but this
process can effect the weather cycle.
 WPT could one day allow us to generate solar power on satellite beam it down to earth.
 It can transmit power to a water treatment plant for a disaster relief operation or power a
flying communication relay station from terrestrial station.
 There are few engineering hurdles yet to overcome to make this technology viable to
todays investors.
 But with the rising demand for energy the rapid improvements being made it is just a
matter of time before WPT becomes an industry of its own.

6. HISTORY:
 The vision of achieving WPT on global scale was proposed over 100 years ago.
 NIKOLA TESLA first started experiment with WPT in New York.
 The development of WPT was not effectively pursued until the 1960’s.
 The development of microwave-powered helicopter platform.
 The successful demonstration of microwave beam-riding helicopter was performed in
1965.
 It proves that WPT could be constructed.

7. The growing in solar energy conversion method and solar applications due to this power
satellite concept came in 1968.
The 1st technical session on SPS was held in 1970 & SPS program has prepared by NASA.
In 1974 the 1st feasibility study of SPS was completed .
In 1975 a successful demonstration of microwaves WPT was done.
Recent studies indicate that collection & transmission of power from space could become an
economically visible.
Very active efforts are been pursued in aerospace community to achieve both of these goals.

8. Why not wires??
i. As per studies, most electrical energy transfer through wires.
ii. Most of the energy loss is during transmission.
iii. On an average, more than 30%.
iv. In India, it exceeds 40%.

10. Transmission Of The energy or power from one place to another place
without involvement or usage of wires
TYPES OF WIRELESS POWER TRANSMISSION
1. Ground based SOLAR power transmission
2. Space based SOLAR power transmission
GROUND BASED SOLAR POWER TRANSMISSION
It’s type of transmission where the sunlight is captured and processed on the earth.
SATELLITE BASED SOLAR POWER TRANSMISSION
It’s type of transmission where the sunlight is captured by Satellite in the outer space
processed outer space.

11. WHY??????
GROUND BASED
 COSTLY STORAGE DEVICES
REQUIRED
 LESS INTENSITY OF LIGHT
 LOW OUTPUT
 WASTE HEAT IS RADIATED IT
CAN’T BE HANDLED
SOLAR BASED
 NO NEED OF COSTLY STORAGE
DEVICES
 HIGH INTENSITY OF LIGHT
 99% OF OUTPUT OBTAINED
 WASTE HEAT IS HANDLED INTO
SPACE

12. Solar Power Satellites (SPS) have proposed to collect so
energy in space and beam it down to the Earth.

13. • There is no air in space, so the satellites would receive somewhat more
intense sunlight, unaffected by weather.
• The SPS concept is simpler than most power systems here on earth.
• Solar radiation can be more efficiently collected in space, where it is roughly
three times stronger than on the surface of the Earth and it can be collected
24 hours per day (since there are no clouds or night in high Earth orbit).
• SPS does not use up valuable surface area on the Earth

14. Four basic steps involved in the conversion of solar energy electricityand delivery are:
Capture solar energy in space and
convert it to electricity
Transform the electricity to radio
frequency energy and transmit it to Earth
Receive the radio frequency energy on Earth and
convert it back to electricity
Provide the electricity to the utilitygrid

18. Advantages
 No fuel required.
 Unlimited energy resource.
 Zero carbon-dioxide emission.
 Solar energy can be more efficiently collected in space.
 No radioactive waste.
 Cost effective(Remove cost of towers & cables.
 Loss of transmission is negligible in WPT.

19. DISADVANTAGES
 Produces green house gases & contributes to global warming.
 The main drawback of solar power energy transfer from orbit is the
storage of electricity during off peak demand hours.
 High cost & require much time for construction.
 Non-renewable energy source.
 Produces acid rain.
 This technology is limited to the use of few technologies, like solar
satellites.
