Solar Power from Outer Space: Microwaves and Frickin’ Lasers

In order to meet our world’s rising energy needs, and to help reduce our dependence on fossil fuels, some ideas that seem right out of a science fiction novel are picking up steam with start-ups and investors. But does using satellites for energy production really make sense financially or environmentally?

Space Based Solar Power (SBSP) is an idea first voiced by scientist Dr. Peter Glaser over 40 years ago, and during times of high energy costs or crises in fossil fuel supplies, the idea keeps rearing its head. 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.
