Think they're ready for polywell fusion?

Someone please correct me if I'm wrong, but my understanding is that it will take between $100 million and $200 million to build a reactor that will determine whether Polywell will yield net energy.

If you ask the more knowledgeable folk here 'Will it?', their answer would be 'Um...well...' and then on into endless esoteric physics...

Does that sound like an entrepreneurial venture that an internet company would be willing to invest enormous sums of high- risk capital into? No.

Google knows about it. They hosted Bussard's "Should Google go nuclear?" talk. 200M is (or was) what they pay in one year's electricity bills.

When I first posted this thread, I did have misgivings in that I can't see milestones between the current work and the $100-200 full-scale system. A venture capitalist wants to see them. But as VCs go, it is not necessary to be the only financier of a project.

I have to assume that EMC2 has some sort of business plan other than just "stay alive", i.e., bring the technology into the terrestrial power and space propulsion industries. But honestly, I can't figure out what it is. (Then again, I don't have any right to know either.)

Stealth start-ups sometimes happen, and it usually means the company has to be very well-financed for the business plan as well as a few hiccups. But that doesn't seem to be the case here, I've never heard of it for a non-profit, and it worries me. We all want to see this succeed (or clearly proven otherwise), and soon. But I can't figure out the path from here to there.

I'm pretty sure MSimon has suggested that an intermediate step could be done for 20M. That may or may not be true anymore.

Cheaper I think. Since most of the $ was for power supplies at $1 per watt and there is a source that can do that for $.25 to $.50 a watt, I'd cut back on the cost estimates - 10M is a nice round number for a continuous operation device (seconds to minutes). It may be possible at that price to do SC magnets.

There are some things we need to learn:

1. Geometry
2. Scaling
3. Losses
4. Continuous Operation Instabilities

Dr. B talked about a 5 year program. It doesn't take 5 years to design and build WB-100. What takes the other 3 years is building and testing enough prototypes so you can do a proper job on WB-100.

I think the immediate goal should be:
5 Seconds of Net Power
