MIT Fusion Researchers Answer Your Questions
1. What have we learned?
Fusion is one of those technologies that is always '50 years away,’ even 50 years ago, maybe even 50 years from now. So, looking at what's actually happened recently: What do we actually know now that we didn't know 10-15 years ago that gives support to the notion that we're making progress? Or, what are the 'big' things we know now? Similarly, what are the things we still don't know that we could reasonably expect to find answers for in the next 10-15 years?
3. Ubiquitous Fusion Power
When will fusion power my house (or vehicle)?
5. What Problems are Holding Back Successful Reactions?
Can you explain to a non-scientist what the biggest stumbling blocks are for an effective fusion reaction? Is it truly a matter of throwing money down an energy hole, or are there verifiable, measurable benchmarks that lead us from one step to the next? I.e. we’ve achieved X, now we need Y; when we get Y, we get Z and then achieve fusion. Is it the technology holding us back, the politics, or the science?
11. What level of investment would get fusion going?
Do you think a program the size of the Apollo program could kickstart fusion to general availability? Or would a smaller program suffice?
14. What could you do with unlimited resources?
Given $1 trillion, the pick of the best brains in the world to work willingly on the project, a large enough location away from any and all governmental regulation and every facility you could ever need - when would fusion be commercially viable?
