Heh, interesting thread. I'm still noobish enough that I had to look up PID loops and ENOB. TGFWikipedia! Of course, I mostly work in a 4GL embedded database language, so all my day-to-day problems are in a totally different frame of reference, but I have enjoyed being able to do things in Progress ...

That's hawt.

I wonder what a 3 million volt transformer will look like.

It's interesting so few people seem to know the project has been funded again already, or that it actually happened last month. I guess the confusion's not terribly surprising, given the lack of press releases. They aren't saying much, so I'm not sure if the r^5 gain scaling is going to be tested in...

That worries me a bit.

Hmm. I wonder if that's going to reliably scale to 100MW.

Only one way to find out for sure I guess.

What is the basis for the B^4 portion of the power gain?

Why does the strength of the B field scale the fusion so dramatically? Bussard mentions this scaling in both the video and the Valencia paper, but I'm not sure what he's basing this on. Was that from his experimental results?

This is a major point I see skepticism on.

You have a steel vessel 10 ft in dia. You have vacuum pumps. You have magnetic grid power supplies. You have cooling water pumps. Once the design is done and you go into production these costs are insignificant. Say $10 mil to $20 mil per plant . Maybe less. Maybe much less. That seems reasonable, ...

Economics of Polywell Reactors -- .022831/kwh to start?

I thought it might be worthwhile to try to determine what sort of cost and useful life we need from Polywell reactors for them to be competitive with current electric producers. Here's a rough guide of electricity prices over the past 40 years. http://www.eia.doe.gov/neic/brochure/electricity/electr...

Nope. We're all waiting with baited breath, but apparently no announcement is forthcoming. I guess we have to just be patient and hope that the results will be published when they're ready.

Oops, no they're not DARPA-related, they're DOE. They just have similar names.

Heh, it does sound perfect. From the guys who brought us the Internet. I wonder if DARPA-E's imminence was a factor in the Navy's re-funding decision. With oil at $80/bbl somebody was going to snap up Polywell, sooner or later. It's interesting Bussard is claiming the $200M Phase II development will...

Well, I hear about things like the alleged Pioneer anomaly and I wonder. And this might explain that. After review, this is interesting, but seems a bit amateurish. I'm not sure how you can fit a positive mass antigravitational particle into the Standard Model, and calling them "transparent" is a li...

Multi-gridded! Cool. And it seems to boost confinement. I wonder if this can be applied to Polywell setups.

Isn't laser induced fluourescence what they used to show the well forming in that Japanese study? Apparently it was too expensive for these guys.

He says there is a difference of at least 10 to 1 between good and bad coders. Given the right tools I can make the difference 100 to 1. True across all programming, I think. And having the right tools is so important. I mostly work with 4GL embedded database languages. I can't begin to tell you th...
