Ok so we have all kinds of neats ideas about Spaceflight.
..But.. try it on a different level...
Project..come up with a drive that works without fossil fuels.
My own design converts electrical energy to momentum energy though not directly.
But I've also heard about a Helium-3 Deutrinium fussion drive, that sounds extremely cheap and clean. Great idea for a back-up drive (to my design)  or for those designing a simple ship with abundantly cheap energy in a point and go style rocketship. Its based of course on the fussion power plant idea. wonderful if we could obtain enough helium-3, but i'm skipping to the punchline.
