UltraSPARC supports 128-bit quad floats:

If we are talking 3D particle simulations machine precision really isn't an issue. It would take an extremly ridiculous number of particles to calculate field values with 30 bit precision. Do you mean 30-decimal place precision? The problem is that it also takes a pretty big number of particles for...

AMD says their latest processor has a 128-bit floating-point internal data path, but they don't say whether they support the IEEE-754r quad precision format:

I must say that AMD's website is pretty badly organized.

So the magnet casings are positively charged, yes? That would make more sense.

MAgrid is positively charged.

How do you figure?

Yet more questions after looking at the animation: 1) Why do we believe that most injected fuel atoms won't just get sucked into the electron clouds surrounding them on all sides? 2) Why would ions that meet but fail to fuse not shoot into the electron cloud (the "wall" of the wiffleball), thus lik...

You are right on the money. I'm using a 64 bit cpu with 1 GB of ram. Way bigger than anything available in the 1990's. And I'm looking at using 250MB of ram for 400 step size block of data in 3D space for the E field, and the same amount for the B field. The accuracy is ok, but for what Bussard is ...

drmike has made some interesting pictures in the "Virtual Polywell" thread: http://www.talk-polywell.org/bb/viewtopic.php?t=203&start=0 This got me thinking about something that Bussard mentioned in his video; it's on page 7 of the PDF transcript: The device is almost electrically neutral. The depar...

Looks like it's back up now.

But, hey, he's got a great Freddie Mercury tribute video:

I've been trying that website all weekend, too, and with the same results.

Does anyone here know the owner?

You need to take the question mark out of the thread title.

But given that the magnetic fields taper off by the 1/R^2 law, wouldn't that mean you have to also square the ampere-turns as you enlarge the radius? Wouldn't that tend to increase losses just from the increased thickness of the coils? Even with superconductors, you can't pump infinite currents thro...

One other thing -- Bussard in the Google video suggested that a polywell design for a D-D/D-T machine would have a 1.5-2m radius and a p-B11 machine would have a 2-2.5m radius (starting at about 1:07:00). I seem to remember 10-20m mooted here -- any reason why your numbers were so much larger, M. Si...
