Garage Fusion (as in subatomic, not a band)

“Taylor Wilson always dreamed of creating a star. Now he’s become one.”

“...[H]e would build a reactor that could hurl atoms together in a 500-million-degree plasma core—becoming, at 14, the youngest individual on Earth to achieve nuclear fusion.”

Achieving a fusion reaction cannot be done with odds and ends taken from smoke detectors.

Are you sure? Don't you need to know what he did exactly before you dismiss it?

Yes I am sure. One needs a source of energy sufficient to overcome the coulomb repulsion of protons in the nucleus and engage the strong force. This requires a degree of energy simply not present in the parts of smoke alarms. By the way, this is why "cold fusion" (so called) does not work. Not enough energy.

The underlying physical reasons are well support by physical theories that have been tested for decades and tested up to the Ying Yangs.

From reading through his site and other info it appears they use a "fusor", which apparently is a device made from concentric metal spheres. Supposedly by filling the device with deuterium gas, and then applying ludicrously high voltages, they can form a plasma of high enough temperature for some fusion reactions to occur. Calling it a "fusion reactor" is sort of a stretch of the term "reactor", because the output energy from fusion reactions is minimal compared to the massive amount of electrical energy being dumped in. (also I don't think the reactions can be sustained in this case)

In any case, if the story is true it certainly is admirable that the kid has so much gusto for science.

Perhaps, but still no fusion with a net power output.
