3. Nuclear Fusion. The holy grail. Forget wind and solar and all that. This would blow them away. It would enable us to produce virtually unlimited amounts of energy and since its fusion rather than fission, there would be hardly any waste.

What about when the amount of fuel you put into a reactor is all used up? When the first element is all fused, what happens next?

If the fuel is heavy hydrogen, you are talking about “burning” water. When you consider how much water is readily available in the oceans, any concern of even using a major fraction of it “up” would be a problem for the next millennium.

I wouldn’t worry about it.
