The idea of Space based solar power was first voiced by Dr. Peter Glacer over 40 years ago, during time of high energy costs and crisis for fossil fuel supplies.
Now, in this worldâ€™s rising need for energy, the idea of space based solar power is helping a lot to decrease our dependence on fossil fuels. But does using satellites for energy production really make sense financially or environmentally?
The premise is that large photovoltaic arrays can be assembled in a geosynchronous orbit at 22,000 miles above the Earth, generating electricity that can then be transmitted via microwave or lasers to Earth.
On the positive side of SBSP, power can be produced 24 hours a day, regardless of the time of year, and the strength of the solar power in space is 6 to 8 times that on the surface of the planet. The drawbacks are the physical logistics and extreme expense of launching all of the materials into orbit, and the lack of an efficient, scalable system for getting the energy to Earth.
