Once we've shown this can work successfully, I think people will get excited and investment money will rush in. Ideally, we'll perfect the technology and make it cheaper and more efficient, just like any other technology. If an MIT-borne fusion startup IPOs and they have a working demonstration reactor, I would probably invest. I think the hope is that with economies of scale, we could build really huge fusion plants one day, and drive down the cost of energy to less than a cent per KWh, and of course completely eliminate our dependency on fossil fuels. If energy becomes that cheap, we could use electricity to produce hydrocarbons from CO2 and water to power airplanes and such. Currently, we can imagine short-distance flights being electrically powered, but transatlantic flights are going to be difficult to achieve with batteries.
