Well, then you just have to invent a fusion reactor that:
- does not work by creating heat but by creating electricity directly (I am sure fusion creates plenty of high energy charged particles to make some electricity), and
- does not require any isotopes but fuses ordinary and plentiful atoms, such as ordinary hydrogen.
Well you are the scientist, get to it. After there are many alternatives but we all know their limitations. Regarding fusion, we know there is a potential for incredible amounts of energy that do not suffer most of the limitations of the other methods.
- DaniFong 17y agoTo your first idea, people have thought of this but unfortunately using ordinary plasma potentials isn't effective enough to drive a current, we have no proven concepts allowing for inductive generation, extraction using photovoltaics is a practical impossibility with decent lifetimes due to the temperature and neutron flux, and other methods of current extraction (e.g. alpha channeling) are very theoretical and still have huge amounts of science around required around them and are limited in efficiency due to a variety of entropy generating processes. As to your second idea, it's already extremely hard to achieve break even with tritium, D-D fusion is even tougher and P-P fusion much much much tougher. We're now talking billion dollar projects, all to achieve an inexhaustible source of heat, which we effectively have in the form of the sun already!
