We’ve seen our fair share of Farnsworth–Hirsch fusors over the years — these high-voltage devices can get ions cooking to the point of achieving nuclear fusion even on a hobbyist’s budget, and even though they won’t solve the world’s energy problems, they certainly make for an impressive light show. While “simple” to build in the relative sense, the examples we’ve seen in the past have still been bulky contraptions supported by a cart full of complex gear befitting a nuclear reactor.
Which is why the fusor [Jay Bowles] recently completed is so impressive. As you can see in the latest Plasma Channel video which we’ve placed below the break, this desktop “star in a jar” not only features an incredibly low part count, but looks more like a movie prop than anything you’d expect to find in a physics lab. If you ever considered building a fusor of your own but were put off by the size and complexity of existing designs, you’ll definitely want to check this out.
Epoxy protects the HV components, plus it looks cool.
The decidedly non-fusor look of this creation can be attributed, at least in part, to [Jay]’s well-known love of building things out of multi-colored acrylic sheets. But you’ve also got to give credit to the transparent walls of the vacuum chamber, which offer breathtaking views of the plasma field surrounding the electrode. In a traditional fusor you’d usually expect a tiny view-port popped in the side of beefy metal tank, but in this case its almost the other way around.
Now to be clear, the build wasn’t ..
