Re: A bit more on hamfesting (buying and selling)

Richard, at these places are the items generally sold as is? I have no real experience so I was wondering? Considering the nature and short time available for these markets, I'd think that might be a given but I don't know. So maybe this aspect should be talked about as well?

Re: Neutron Club Application - Erik Smith

Congratulations on being accepted; while your count is extremely low for the pressure and current, that may be due to your neutron detector (I do have questions on that)and/or your electrode design. Maybe that rather limited electrode is causing the lower flux readings - your pressure should, I'd th...

Re: Optimal Deuterium Gas Pressure?

Deuterium gas pressure determines current when a given voltage is set (for a given system and assuming a sufficiently low pressure is reached); so, if one sets a voltage and as the pressure falls, the plasma will suddenly start conducting, which ignites the plasma (the current will surge, then lower...

Re: Good Afternoon from Central California

Building a demo fusor is not very difficult (compared to a real fusor) and can be fairly safe if one uses a minimum of caution and reads the FAQ's, and asks questions here when in doubt. A NST (see FAQ's for that) are fairly safe (but one can kill one's self if you are extremely foolish) and creatin...

Re: First Plasma

Any gauge that contaminates your system tells you nothing except how to waste your time and efforts. Throw that junk away. Also, those connections on the chamber (besides the acrylic window) are not suitable for any real vacuum system. Creating a vacuum has enough issues for a novice without using a...

Re: Regional Science Fair Success - but still a long way to go

Congratulations on your success. As you are starting to understand, one needs to be careful discussing issues about natural phenomenon's like solar flares. These are and have been extensively studied by astro-physicist and theoreticians for many decades. Your first duty is to read experts on the fie...

Re: Design Foundation?

Another Question: Could we collect the ejected electrons and use them in the energy as well? Not fully clear what you are getting at but excited electrons in a fusor are not useful nor available to do work. The issue is the electric field - that generates the force for the deuterium ions and disrup...

Re: Design Foundation?

As someone who has built both such devices, a fusor is far away easier. An accelerator requires very high voltages that are very difficult to achieve. A Van Da Graaff is not doable for most people (there are exceptions but I still have not seen a real working accelerator posted using a VDG.) I did b...
