Fusor in action 130%

- July 15th 2014 - at The Geek Group of Western Mass. Farnsworth-Hirsch fusion reactor (aka "A Star in a Jar") 130% power operating on one leg of a 15kV neon sign transformer. Not enough for fusion but a good start and nice stable plasma.
I only found this 7 years later, this is amazing

that was freaking amazing, incredible work. what an inspiring demonstration of a passionate DIY maker-mindset. I must ask... are you getting bathed in x-rays?
The power levels were far too low to start producing fusion or any byproducts or x-rays, the pressure level needs to be much lower and the power much higher. This was a demonstration fuser, Basically a glorified light bulb, but proof of concept.
@TheValveBoy ohh well what a glorious lightbulb it was! XD
A very cool exploration of physics nonetheless, thanks for sharing!
The future of space travel
Awesome build! Did you ever test to see how long the inner grid lasts before melting? Do you have any plans to get another transformer (or two) and go for actual fusion?
The original inner grid I made was out of soft copper wire. It melted/vaporized in a few spots after a few runs of 10 min. I made a tungsten inner grid that has lasted so far, from the filaments of old quartz heaters. If I can scrounge the parts together I would like to go to the fusion level. The equipment needed gets pricey quick. Ultra high vacuum pumps, and all the extras piping and gauges and chambers cost quite a bit.
@@TheValveBoy you can make an ultra high vacuum by using sprengel pump :)
@@121sunita Why did you have to say that? You just had to say that, didn't you? Now that I hear it from someone else I _have_ to build one🤣. I was thinking about making one just earlier today for this exact purpose and here you are giving me positive reinforcement, now I have to go buy a bunch of glass lol. At least I already have 3.5 pounds of Mercury, that will make this project a lot cheaper...
Eric Dollard says that he has seen the purple light exit a pinhole in the glass of a very large tube as if it was escaping purple gas hissing outward. How is that explained if a vacuum tube has a vacuum inside? Dielectricity?
In my video I think what you see is the reflection of the light in the glass chamber not that there is anything escaping.
Is "hitched up" a scientific term?
why did you make your video through a keyhole ?
The video was taken on a iPhone
What's your x-ray dose per minute?
Linuxbrad this is a demo fuser it’s about as dangerous as a incandescent light bulb at the power levels and vacuum I was operating at.
Can tony stark use this to power his body armor?
So cool
Can you explain how this works?
en.m.wikipedia.org/wiki/Fusor
This will explain it better than I can.

How much energy you used?
It was powered by a neon sign transformer 120V generating 14kV, at about 490W, so not that much. This fusor was also a demonstration unit, so it was basically a glorified light bulb.
Where is the helium?
StreamWARE there is no helium the chamber was under a vacuum. The Purple glow you saw was residual atmospheric gases. High end researchers use much better vacuum pumps to achieve a higher vacuum level and a lot more power. This was akin to a light bulb in comparison to what a actual set up can do. A cool light show but not capable of producing actual fusion.
Thanks for asking a question
@@TheValveBoy Well i was thinking about making a fusor with helium inside of it, do you have any advice? Im going to be using 12kv
StreamWARE if you want to do research check out
www.fusor.net/board/
Deuterium is what you need not helium, 12kV is in the starting point of fusion but you have to pull a very high vacuum and inject a trace amount of deuterium into the unit. If you manage that your going to need shielding as well, as you will start to get neutron production as well as x-rays and a UV light. Do some research, talk to others on the boards and be safe, 12kV will kill. Respect what your going to be playing with or it will bite you.
Other people who are working on this are a great resource and know a lot more than I do about this. My unit was a demo unit little more than a cool looking light bulb.
Stick to it and good luck
Yeah it's called a light bulb
a light bulb isn't a plasma discharge chamber
@@goatmeal5779 neon light are
can it make electricity?
At this point ....no, but there are a lot of people out there with much more advanced set ups than this that are getting neutron and X-ray production as well by products of the fusion reaction. The key of course is to find a way of harnessing the energy of the reaction and getting past the break even point. Which no one has done yet.
electricity from it can power part of the building.
it can but its not practical. its more of a cool experiment thingy
build up to that point. it could power the lab (and more).
@@TheValveBoy I have a feeling that fusion in the stars only works because of pressure exerted by gravity. Since that pressure doesn't come from any source but the mass of the star itself, energy can be produced after fusion. The fusion reactors here on earth are trying to create magnetic fields to create the same pressure but we won't be getting net positive energy out of it because of the above reason I have stated.
Are you still alive?!
Very much so… this was a demo fusor about as dangerous as a fluorescent lightbulb.
I am happy to hear that! ☺️
