When it finally works, you will have invented the most expensive form of energy we've ever imagined. Congratulations.
I mean, don't get me wrong, I'm excited for fusion. Fusion has some amazing potential as a power source and propulsion for space ships. But outside of that application, I don't know... I'm pissemistic. I do not think it will be the global energy revolution so many people seem to think it will be. It will not be unlimited cheap energy, not be a longshot.
