Fusor Forums

Agreed; her overall talk is outstanding and summorizes the main issues with ITER and to a lesser extent, fusion in general (via magnetic fusion.) While the stellarator approch cannot suffer from containment failure I still agree it too would be far too expensive to succeed as a power plant. Further,...

If you can get basic funding to work on some of the ideas then you have certainly crossed a milestone that really few outside major labs can say. AS for ideas that might work, again, as you also pointed out the stellarator is certainly in that class and the Germans have made amazing progress (on pla...

Nice work making those detectros and displays. Congrats on the plasma club. Great first step towards the neutron club, too.

First, once 'free' via vaccination I would think that people interested in fusor's and/or even building these devices would likely be more inclinded! Being able to get out and get items should help encourage people to get their projects past the thinking stage and get to the construction phase. For ...

Certainly Pons and Fleishman simply released ordinary chemical energy in their work. But fusion using ions is still a possiblity. I've talked to experts and they feel that ion beam fusion might result in net energy - current accelerator tech can produce a beam at about 20% efficiency. This is certai...

If you do build your own supply, please do post your design and details as you progress; a lot of people here would find that very interesting.

Speaking of large machines that limp along with large funding the (South) Korean "Star" tokamak proves that not only are these machines essentially worthless (for future possible fusion power plants) but even adding just a few extra seconds takes years of efforts. This would be sad if not for the fa...

Certainly true relative to fusor work; however, one should add that over the last few years there have been a few important advances on the hardware side: the development and now rather common practice of using deuterium water to create deuterium gas for a fusor has really matured. The practical dev...

The cost of large diameter and long glass cylinders is rather up there - especially the thick glass you will need for safety; also, a plastic housing will be needed if you want to operate in a school environment. Pumps (on ebay) can be cheap if one waits for deals. I found rather inexpensive vacuum ...

A demo using a NST shouldn't get too hot - that metal plate should keep the seal at the ceramic/metal interface stable with its large heat capacity and cooling area. One thing I'd suggest is don't use multiple layers of different materials to seal the feed-thru. The differntial thermal expansions ra...
