I’m a member of a group of young fusion researchers who are trying to figure out how to make fusion happen in our lifetimes. This is nontrivial because ‘young’ in this case means under 40, and current plans from DOE don’t put fusion power on the grid for another 35+ years. Given the accuracy of government forecasts a whole year down the line, I’m not holding my breath.
I think that the single largest factor holding up the development of commercial fusion is not physics, its program structure. We need to revolutionize the way fusion research is structured, and the best way to do that is to bring the power of the market to bear. Prizes have been suggested (notably by Bob Bussard). I offer here an alternative proposal, seeking your feedback.
The goal is to encourage private funding. This means finding a way to reduce the risk to investors in potential fusion schemes. If a given idea can pass a basic peer reviewed sanity check (doesn’t violate any laws of physics), DOE should offer to insulate investors from some measure of risk. As a concrete proposal, say DOE will purchase all the intellectual property assets of any innovative energy company which closes down after raising private venture funding. There would be some limit, indexed to the amount of money raised, say 1/2 the total venture funds raised, up to a limit of $50 million expended by DOE per company. The physical plant would remain property of the investors or creditors. DOE would pay an external auditor to catalog and organize the intellectual property assets, and would make them freely available to interested parties.
There would have to be sensible mechanisms for peer review and for deciding when to shut down (presumably the investors would make that call), but I don’t see showstoppers there. I think the idea would work, but getting congress to agree is likely to be hard. There’s a real danger of the money disappearing after a venture is funded, thanks to diversion to some more worthy cause, like rainforests in Iowa.
Anyway please comment, kvetch, suggest, advise, discuss, either in comments here or in email to me.
