SPACE BASED SOLAR POWER
[attachment=58340]
ABSTRACT
Space-based solar power (SBSP) is a system for the collection of solar power in space, to meet the ever increasing demand for energy on Earth.
In SBSP huge solar panels are fitted in the large satellite which collects the entire solar energy present in orbit and beams it down to Earth.
The collecting satellite would convert solar energy into electrical energy on board, powering a microwave transmitter or laser emitter, and focus its beam toward a collector (Rectenna) on the Earth's surface.
INTRODUCTION
Humanity's demand for energy is growing at an astonishing rate due to the exponential increase in population
In outer space there is an uninterrupted availability of huge amount of solar energy in the form of light and heat.
In 1968, Dr. Peter Glaser introduced the concept of a large solar power satellite system of square miles of solar Collectors in high geosynchronous orbit for collection and conversion of sun's energy
SOLAR POWER SATELLITE SYSTEM
The concept of the Solar Power Satellite (SPS) is very simple. It is a gigantic satellite designed as an electric power plant
orbiting the earth which
uses wireless power
transmission of space
based solar power.
CONVERTING DC TO MICROWAVE POWER
To convert the DC power to microwave for the transmission through antenna towards the earth’s receiving antenna, microwave oscillators like Klystrons, Magnetrons can be used.
The magnetron uses the interaction of magnetic and electric field in the complex cavity to produce oscillation of very high peak power.
TRANSMITTING ANTENNAE
Power transmission via radio waves can be made more directional, allowing longer distance power beaming, with shorter wavelengths of electromagnetic radiation.
Retro directive beam control systems have been the preferred method of achieving accurate beam pointing.
Microwave power beaming can be more efficient than lasers, and is less prone to atmospheric attenuation caused by dust or water vapor
CONCLUSION
Space Based Solar Power System requires enormous expenditure and man power and the concerns about the radiation and doubts about the efficiency and feasibility make us think twice about the feasibility of the project. but it cannot be ignored that Space-based solar power offers energy from an unending source with no emissions and very little environmental impact.
All in all, the positive aspects of such a system appear to outweigh the negative ones
Given the incredible benefits, not to mention the tremendous need, it's a no-brainer that this needs to happen.
