This article is about the real thing, which is substantially more difficult to build.
If it does, it's fusing. If not, it isn't.
Hopefully mother nature decided he would be the chosen one to make fusion reactor net positive
I mean I hope for all of us this is one of those cases.
It's worth reading the whole article. The Fusor design has a long and fascinating history. One of the original inventors, Farnsworth, invented television.
Oh that familiar rascal... Always getting the better of positive energy output.
Please humor me. Does this mean that if the LHC had x diameter, it would perform the same if it was 1km in circumference?
It's not the diameter of the tube but the diameter of the circular path the particles follow through the ring. The greater the circumference the less the relative angular acceleration (i.e. shallower curvature). To accelerate particles even faster without giving up most of the extra input energy to bremsstrahlung radiation you must increase the circumference to maintain the same relative angular acceleration.
It's Friday and math and physics is not something I can do off the top of my head so at this point it's better if someone else step in. I won't be able to describe it correctly without relearning half of this stuff myself.
 I mean... the algebra and geometry is rather trivial but it'll take some effort for me to correct and make more precise the terminology and formulas.
...is the LHC track a circle?
Edit: just acknowledging the funny set of identical replies!
This particular achievement is notable because Jackson Oswalt might have been the youngest person to home-build a fusor, or at least the youngest to have spoken up about it.
Also worth noting that this is a year old. Looks like he's been plugging at it since then:
By your gigaton number then there will be on average less than one atom of his CO2 production in 50,000 years .
What happens if we consider total carbon footprint instead? Various sources cite around 20 metric tons per year as the average carbon footprint for someone living in the US. That's about 120 times higher than the amount exhaled, and since log(a*b) = log(a) + log(b) we can just add 3540 years  to our above calculation ~= 54,000 years.
So above a millennium, but much less than a billion years.
There's no-one from before the chess + computer age on the list of the 36 players who've become Grandmasters before their 15th birthday : https://en.wikipedia.org/wiki/Chess_prodigy#List_of_youngest...
Just the right amount it seems.
Any one of the four lacking would have stopped this project cold. It’s no small feat for a small child, even with a big budget, it’s a good measure of the other 3 traits to take this project on and reach this milestone!
In fact, if the claims are true, he will have beaten Wilson's record as youngest person to have produced nuclear fusion using a fusor.
It's mind boggling what dedicated kids can achieve with parental backing and scientist mentors. In Wilson's case places like The Black Hole surplus store (https://www.roadsideamerica.com/story/18130) also greatly helped. Sadly such places are getting rarer.
Edit: sibling points out it may be $10k. I wonder if that price includes other equipment not shown. If not, apologies for the gross underestimation ($1.5-3k seemed reasonable - most of the equipment pricing can be looked up).
Fusion is something we hear about in the media as being something very hard to achieve. It’s not. Achieving fusion beyond breakeven - so we can generate power from it - now that’s a very hard problem. It takes the combined effort of seven countries and billions of dollars.
I've heard of the "young Earth" movement, but "young Sun" is a new one.
