How about a salvo with nichrome wires built in as a heating cylindrical barrel of a regular pneumatic and it would minimize blowby and possibly crumpling of the toast. If it all needs to be automated, control could be done by a simple microprocessor and potentiometer with electrical contacts put ...

Fusion Reactor

I'm building a 50kv/5mA supply for the fusion reactor. Building a bottled deuterium injection and metering system for it. Building a 6" spherical stainless steel chamber for it with conflat vacuum hardware. Building a linear ion accelerator based on the magnetron principle to run ...

In this recent ad from google for chrome, google compare's chome's speed to a variety of things, one being a combustion spudgun. The high speed footage very clearly shows to deflagration of the fuel in the chamber, and the acceleration of the potato. It's some cool stuff.

Spudgun Footage begins at ...

On my 10' spudgun I placed the barrel support too close to the breech, and had no supports to hold the barrel down. After a while, this placed lots of stress on the fittings connecting the piston valve to the chamber, eventually causing the to fail. The failure resulted in the barrel (still attached ...

Thanks for the complement Big-E, and I'm taking special care not to burn down the garage.. or irradiate pets for that matter...

Don't worry, I'm staying in school and going to college (and grad school).

I haven't decided what option I will go with in regard to deuterium, however, the electrolysis (hoffman apparatus) seems to be the cheaper route.

I got about $450 from district 5, $100 from neosef.

Yeah, you can get a lecture sized bottle for about $150, or you can build and electrolysis machinge and make it from heavy water.

And yes, i did the majority of my research on fusor.net

I think the ending price for fusor mk.I was around $500, granted I was able to get a vacuum pump for free...Fusor mk.II 's chamber has already surpassed that, but I can fund that with my winnings from the science fair.

There are few practical applications for this one (although I won over $500 in prizes at my district science fair) other than research, there are even easier ways to do neutron generation. And i am not going to attempt fusion in this one, but I will use a 6" diameter spherical chamber made of ...

Knowing the kinds of people on spudfiles, I thought that you guys might like to see this.

During my short and now-ended hiatus from spudding I directed most of my time and efforts towards designing and building an Inertial Electrostatic Confinement Nuclear Fusion Reactor (IEC fusor or farnsworth ...

Ok, you should expect a physical result around late February, I'm very busy at the moment with a huge science fair project and midterms.

I think I might have made my diagram too vague, the direction of airflow is from right to left across the diagram, the vortex generator is mounted at the end of the barrel and in theory should produce the vortex from the accelerated air from barrel.
