Re: Deuterium Lecture bottle

My first bottle of D2 was purchased back in 1998 through the local Welders Supply. I prepaid them at the store, got a receipt and a week or so later was called to come pick it up. When I picked it up, they helped me identify the fitting I needed to mate the bottle to my gauge. They had it in stock. ...

Re: What is swagelok?

Swagelock couplings are typically used for gas port entry and gas plumbing line connections at the amateur level. Pros tend to use VCR fittings at 4 times the price. Swagelock also makes some valves for gas lines and thimble metering valves as well.

Re: Overview of D-D and D-T Fusion Detectors

A GM tube in the vacuum would measure only x-rays and probably swamp out to a gentle arc condition, which typically ends the tube's life. A GM counter outside of your beam device would also go crazy as X-rays penetrate the device as you approach fusion voltages. Forget any attempt to use a GM tube o...

Re: Creation, usage, and destruction of a cathode

Very nice setup for a demo device. Enzo is learning that the operation of even a demo fusor requires full time and attention to every detail. He did a great job of fusing his new grid. I like his method of making a simple, yet very effective grid for his demo system. I am glad dad is around to sheph...

Re: Wendelstein 7-X has successfully finished its second major experimental run

Energy discussion are fine as long as they don't get political. Energy is a major issue and fusion is at a forefront of promised solutions, yet to be delivered. None of us want increased energy prices, but they will surely come. John, thanks for the update. I did not see the erased part of the text....

Re: Gamma-ray Spectrum, CP-1 Graphite Memento

Nuc Lead is a company that deals in many lead products. One is "virgin lead" It costs a good bit extra as it is lead that was mined over a hundred years ago and is usually in the form of buried pipe, underground electrical buried covering, ancient ballast culled from old sailing ships, etc. I may ha...

Re: A Thought Experiment on Ideal Conditions

Good fusors regularly hit the mega n/s mark. ( 2 million fusions/s +) Grid losses in any fusor is pitiably small. There are many other losses of greater import keeping the fusor from improving. These have been discussed at some length in past posts. The grid is of no real concern, loss-wise. Due to ...

Re: Gamma-ray Spectrum, CP-1 Graphite Memento

As I understood it, there was no core in the classic sense in CP-1. Instead, the fuel was distributed all about and within the moderator in a manner that would allow moderation of purely natural uranium fission over the bulk of the volume. Explains the low power over a huge volume. I do not know how...

Re: Wendelstein 7-X has successfully finished its second major experimental run

Regardless, Fossil fuels will be the major suppliers of all electricity for a very long time to come. Fission will trail at a distant second. Renewables will never, ever, make honorable mention on a global scale. Current fossil fuel plants, actually planned or under construction world wide, number i...
