Technology Challenges

Low-Cost, Environmentally-Friendly Launch Vehicles - Cheaper, cleaner launch vehicles are needed.Large Scale In-Orbit Construction and Operations - To gather massive quantities of energy, solar power satellites must be large. Power Transmission - Small effort is needed to assess how to best transmit power from satellites to the Earth’s surface

High Development Cost - Space solar power development costs will be very large.

Potential Health and Safety Impacts – Flora and Fauna

Life Cycle Costs – 50 years vs.???

Location Competition – GEO population
