So from what I read at our current technological level just about the perfect way of powering and moving ships through space would be a combination of ion propulsion and fusion reactors. Does that seems like a fair thing to say? Would it open the solar system up to humans?
I’d personally say that by the time they get the DEMO commercial fusion reactor up by 2040 (at least that’s when it’s planned) It is set to produce 2 GW. By 2040 we should have a souped up enough ion engine for it. And knowing human progress a decade or two after the DEMO reactor we’ll probably find a way to produce the same amount of power in a smaller package.
I personally believe that as long as things go the way they are it’ll be inevitable that humans will spread out across the solar system.
