Wireless Power Transmission via Solar Power Satellite- ECE Seminar Topics

INTRODUCTION TO SPS :

A major problem facing Planet Earth is provision of an adequate supply of clean energy. It has been that we face “...three simultaneous challenges -- population growth, resource consumption, and environmental degradation -- all converging particularly in the matter of sustainable energy supply.” It is widely agreed that our current energy practices will not provide for all the world's peoples in an adequate way and still leave our Earth with a livable environment. Hence, a major task for the new century will be to develop sustainable and environmentally friendly sources of energy.

Projections of future energy needs over this new century show an increase by a factor of at least two and one Half, perhaps by as much as a factor of five. All of the scenarios from reference 3 indicate continuing use of fossil sources, nuclear, and large hydro. However, the greatest increases come from "new renewables" and all scenarios show extensive use of these sources by 2050. Indeed, the projections indicate that the amount of energy derived from new renewables by 2050 will exceed
that presently provided by oil and gas combined. This would imply a major change in the world’s energy infrastructure. It will be a Herculean task to acquire this projected amount of energy. This author asserts that there are really only a few good options for meeting the additional energy needs of the new century in an environmentally acceptable way.

ADVANTAGES
· Unlimited energy resource
· Energy delivered anywhere in the world
· Zero fuel cost
· Zero CO2 emission
· Minimum long-range environmental impact
· Solar radiation can be more efficiently collected in space

DISADVANTAGES
· Launch costs
· Capital cost even given cheap launchers
· Would require a network of hundreds of satellites
· Possible health hazards
· The size of the antennas and rectennas
· Geosynchronous satellites would take up large sections of space
· Interference with communication satellites
