The main thing that's missing in energy is an incentive to create things that are zero-CO2-emitting and that have the right scale and reliability characteristics.

I'd put my money on the sun and solar energy. What a source of power! I hope we don't have to wait until oil and coal run out before we tackle that.

If you're willing to change the world, let love be your energy.

I have had a lot of success with failure.

Not only will atomic power be released, but someday we will harness the rise and fall of the tides and imprison the rays of the sun.

The nuclear approach I'm involved in is called a traveling-wave reactor, which uses waste uranium for fuel. There's a lot of things that have to go right for that dream to come true - many decades of building demo plants, proving the economics are right. But if it does, you could have cheaper energy with no CO2 emissions.
