dnavas, The government forced banks to issue unsound loans. The federal government did not force banks to accept liar (unstated income) loans. The market did. When all the upstarts are accepting them, then you do as well, or you go out of business. In fact, Freddie and Fannie were prevented by law ...

That's a completely unfair assesment. My understanding of the current economic crisis is that it is the result of people defaulting on sub prime mortgages. It appears that under pressure from the government, loans were given to people who never should have gotten them, and could not pay them back. ...

dnavas, The cow thinggie: it is referred to as "The Tragedy of the Commons". What causes it? No one owns the commons. It is not a failure of the market. Awesome! I'll probably forget what it's called in another half dozen days, but I appreciate the pointer. And highly ironic the context I...

>>> Market forces are driven by people who freely choose to spend their money as they see fit. Sometimes these people do foolish things in excersizing their freedom to wastefully burn fossil fuels, but the market will punish them eventually and Nature will put things right. <<< Ah, if only that were...

The greater the peak output the more closely they have to be mixed. Agreed. I would restate your original as high w/kg is not conducive to stability. Agreed batteries carry both an oxidizer and a reducer, which makes them marginally less safe than a fueled vehicle (and heavier). The trick is to hav...

Batteries are going to be a problem in accidents since they can release a significant fraction of their energy in under a second. That is explosive. It's all chemical reactions, whether it's gasoline or lithium. Gasoline vaporizes, whereas lithium ... The problem with lithium batteries (at least mo...

TallDave, maybe only 20 to 50 mill for a 160cm device. Actually proof of scaling can come far cheaper, WB-6 has 30cm coils, build one double the size, 70cm, and we should hope to see 128x the output. I think that might be done for 3-5 million. Easy. Scaling is not the only concern, though, surely? ...

However, as far as the plasma is concerned these are steady-state discharges. The 100 microsecond to 1 millisecond discharges are longer than any of the plasma timescales. Consequently, the physics learned should have application to steady-state devices. Hmm, well, ELMs seem to occur at a much slow...

They look at the Polywell and see an idea that they think they laid to rest a long time ago and now it's threatening to cut off their funding even though they think it has no merit. Sure, though it's hard to see how $2M can be viewed as much of a threat. They may have even been right -- that Polywe...

Maybe that's why the Chinese and Russians are so focused on going to the moon to mine Helium-3 for?! Err, wow.

It might be useful to do multiplies on the accelerator and adds/subtracts on the main processor. Unless they are MADDs, as those tend to run in a single cycle on GPUs.... 64bit isn't that far away for GPUs, the issue won't be computational intensity, it'll be memory. 1G video ram is terribly rare. ...

Well, I took a giant step back and found a lot of stupid ideas :D But it led me to an idea which I haven't seen bandied about, so I tried one that looks pretty good. I simply changed the E field on the MaGrid from static to be cos(w*t). Sorry for being dense -- what's the frequency here? I would th...

Novice configuration WB7-8 questions

I'm trying to understand the conflicting messages I'm getting wrt WB7/8's configuration, and the rest of Dr. Bussard's google TechTalk. 1. My reading of the text leads me to believe that the hoop/rings will be replaced: "but would not use circular coils, rather they will use coils that follow t...
