Spaceships that harness the sun's energy as a source of something renewable and perpetuating travel.

There is no solid prototype other than the skeletal idea. It would be a ship the shape of which is yet to be determined but it would allow the ship to harness the full solar power continuously collected and would allow space travel for longer periods. The problems I see are harnessing such energy and converting it in a way that would propel the ship at faster rates than conventional fueling methods.

    Mar 5 2012: No you're right @ edward it isn't renewable but its sustainable a lot longer than the fuel used at present.

    @Doug thanks for the info I'll be sure to look into the ion engines. That sounds like something that might be even better than some sort of high powered solar panels.
