Mr. Fusion Comes Closer

Posted by michael on from the just-add-banana-peels dept.

doktoromni writes "The first experimental, sonofusion-based, table-top fusion reactors are now being commercially sold. Although those reactors are not breakeven (yet, would say an optimist), they are by far much cheaper than other fusion approaches, like magnetic and inertial confinement. Also, they open the possibility of portable fusion reactors, along the lines of 'Back to the Future'..."

    Well,actually, it doesn't break even, according to the article. So I suppose that even though you can get a thousand years worth of energy out of that gallon of heavy water, you'll actually have to put MORE energy into the system. It would be more efficient just to use the gas right now. However, maybe this will lead to more people researching fusion and possibly help bring about a simmilar system that will produce more energy than you need to trigger the reaction.
