Re: Breakeven Laser Induced Ultradense Deuterium Fusion Clai

I don't think they are talking about molecular species spins. Nuclear spin states most likely. Possibly Rydberg electron spins for the 100 nucleus cluster. They use an Fe2O3 catalyst to form the condensed Deuterium state (at defect sites). 1,000,000 times denser. Sprinkling a pile of dry powdered Fe...

Re: Breakeven Laser Induced Ultradense Deuterium Fusion Clai

From the Winterberg abstract here: http://www.sciencedirect.com/science/article/pii/S0375960110004949 Seem to be saying that it gives off energy to form the dense state, which might explain the anomalous heat given off from "cold fusion" experiments. Not real fusion at that point, just a state chang...

Breakeven Laser Induced Ultradense Deuterium Fusion Claim

Big news if this is for real:

Only a 0.2 Joule laser, some actual Watts of energy output. Only high energy charged particles produced, no neutrons.

Re: Old Turbotorr Pump Servicing

The ring of threaded holes around the top shaft is (I suspect) for balancing the rotor (aka: tire weights). Notice the insert in one of the holes. If it is disassembled, you not only have to get the order of the parts correct on re-assembly, but the rotational phase of each disk. Probably best left ...

Re: Old Turbotorr Pump Servicing

From what I can just make out of the top shaft thread in the picture, looks like the "off" arrow is pointing the wrong way. Check the thread carefully to see which way actually gets the nut off.

" Record low temperatures here in Sweden right now in May;......"

It is called the Atlantic Duodecal Oscillation. Nothing to worry about. Sky is not falling. Enjoy the cool weather while it lasts.

Re: One unnamed diffusion pump.

That's a Varian HS-2 or NRC 0160 (same thing, Varian bought up NRC) The water cooled baffle up top is not one of the standard Varian units, could be a custom machine shop design. Looks like it was a rebuilt one, probably by Idealvac. The Varian is normally olive green color. The two fittings on the ...

Re: Turbo shut down with high foreline pressure

I have a Pfeiffer TPU 060 apart for bearing replacement here. Looking at the old bearing, the inner race has a taper on one side, which would make for a larger gap between the inner and outer race when assembled. However, the actual ball track in the center of either the inner or outer races appears...

Re: Glass vacuum chambers, a good idea, or just plain stupid

Occasionally large diffusion pumps come up for sale on Ebay that are cheap enough to just use one for a vacuum tank. Right now there is an 11" OD flanged one listed at $99. There were a bunch of VHS-10 units that sold this last summer for $350. They were almost the size of a barrel.
