To claim that solar power is too weak to power the world is simply wrong. We use so little of the solar power that arrives for free from the sun and investment in using more of it efficiently will not have the potential cost or nightmare consequences of a nuclear meltdown.
Climate change denial does not stop irreversible extinctions and “being real” by building nuclear plants on or near fault lines or population centres is plainly daft.
What commercial imperative is there for free energy? Free energy is the most efficient form of energy. It would mean we can spend more on the very real problems we face from polluting the seas.
