I am very pleased to learn about your involvement in the energy future of our planet. I agree that clean, affordable and available energy is the overriding issue for the future development and well being of the entire human race.
My wish is that you will take a serious look at space-based solar power. I believe it can be a game-changing base load power source. When funded, developed and deployed at the required scale, space-based solar power addresses your requirements for zero carbon emissions, ease of distribution, relatively small earth footprint and zero waste generated.
Uranium is a finite resource, though longer range than conventional fossil fuels. Space-based solar power can provide energy to the earth until the sun burns out.
The website Citizens for Space Based Solar Power is one of many places to begin a review of the current state and potential for space-based solar power. You could be the voice this technology has been seeking.
