Entertaining to watch Red regurgitate tired old "nuclear fusion will save us" memes.
Thing is, we HAVE nuclear fusion. A successful reactor has been running for the past five billion years, about 93 million miles away, sending us all the energy we need.
You can collect it either by harvesting mechanical energy from the air currents the reactor sets in motion("wind," they call it, except in a musical with Lee Marvin) or by directly harvesting photons in either a thermal converter or a photovoltaic one.
All that stands in the way of fully tapping into this fusion reactor is the retarded fuckery of small and sclerotic minds.
