Re: Hybridized Polywell Design Theory of mine

<t>I'm simply looking for honest, blunt critiques.<br/> <br/> The SERL stuff is just something I want to experiment with in a gyroscopic system to see what effects it does on fields. I know the damn thing doesn't work like he "advertizes". Just a crazy old coot going senile but the centripital/centr...

Re: My fusor

Eesh, definitely not pretty but hope it works like you hope and good luck with the pump.

Re: Hybridized Polywell Design Theory of mine

<t>Well, I'm coming back to my design and looking at some concepts that might work well together. So feedback on the following would be greatly appreciated.<br/> <br/> Looking at combining the standard spherical fusor chamber with a variation on either the SERL "generator" electromagnet setup (will ...

Re: My fusor

As long as it runs safely and you get results, looks don't mean a thing. Hope to hear results on the pump hunt and if you can get any readings once it's up and running.

I'm a long-haul comm technician and we use this diagram as a joke to new guys.

Re: Found better material for chamber construction

<t>I'll attempt a price quote for a pair of 6" and 12" dia. hemispheres without ports and some of the TiO2 treated rubber components and get back to you.<br/> <br/> On a sidenote: my roommate's got a better paying job now so I'll have more free cash to start scrounging and other serious component ac...

Re: Found better material for chamber construction

<t>Well, getting the titanium dioxide treated gaskets, seals and tubing wouldn't be all that expensive and would allow some to achieve better vacuum pressures for longer. Since outgassing is always an issue regardless of price or complexity of the reactor.<br/> <br/> Research and youtube is pretty m...

Found better material for chamber construction

<t>Was researching material properties and irradiation performance tests from various safety commissions and manufacturing groups when I came across some nifty information.<br/> <br/> It appears that even in the large fusion and fission reactor projects, they still use stainless steel but folks like...

Re: Making my own bell jar reactor

<t>Chris has the idea of it. For voltages a bell jar fusor can safely run at, you shouldn't need more than 1/2" thickness glass.<br/> <br/> I'm still looking into what thickness is necessary to withstand the vacuum pressures for a viewport. I'll also look into whether or not one of these manufacture...
