    well, i sort of got an idea on fusion.
    why not use fission to generate the energy to create fusion energy?

    actually, just realized thats how hydrogen bombs work. :P
    but why hasn't this been done?

    hmm.. wiki article says to use radioactive decay for power.
    that'd be awesome:

    Fission isn't all that scalable. To get a fission reaction large enough to power fusion, you pretty much need a bomb. Needless to say placing a bomb inside a building isn't a good idea

    This is pretty much the mechanism used in the hydrogen bomb.

    Here's one fission-fusion hybrid:

    Though it uses the fusion not for energy, but to reduce the amount of waste produced.

    I personally favor the use of concentrated radiation to give the energy to the hydrogen, so as there would be little to no radioactive fallout from the reaction (radioactive waste). Some sort of magnetic containment and massive radiation generators of some sort. I know this is vague, but I feel it would be the general framework for a successful fusion generator.

    you keep using the phrase "of some sort", isn't that the main barrier to implementing any of this technology? If the some sort part was answered it's a done deal, till then ??????????????????
