Radioactive Boy Scout

Teenager achieves nuclear fusion at home

by Stephen Ornes
http://www.automotiveforums.com/vbulletin/fusion-device.jpgIn 2006 Thiago Olson joined the extremely sparse ranks of amateurs worldwide who have achieved nuclear fusion (http://www.jet.efda.org/pages/content/fusion1.html) with a home apparatus. In other words, he built the business end of a hydrogen bomb in his basement. The plasma "star in a jar"—shown at the left—demonstrated his success.

For two years, Olson researched what he would need and scrounged for parts from eBay and the hardware store. Flanges and piping? Check. High-voltage X-ray transformer? Check. Pumps, deuterium source, neutron bubble dosimeter? Check, check, check. “I have cross-country and track, so during those seasons I don’t have much time to work on it,” says Olson, a high school senior in Michigan. “It’s more of a weekend project.” Last November the machine finally delivered the hallmark of success: bubbles in the dosimeter. The bubbles indicate the presence of neutrons, a by-product of fusion—an energy-releasing process in which two hydrogen nuclei crash together and form a helium nucleus. Fusion is commonplace in stars (http://www.enchantedlearning.com/subjects/astronomy/stars/fusion.shtml), where hydrogen nuclei fuse in superhot plasma, but temperatures that high are hard to achieve on Earth. Still, the prospect of creating all this energy while forming only nonradioactive helium and easily controlled neutrons has made harnessing fusion one of the most sought-after and heavily funded goals in sustainable energy.
Olson’s apparatus won’t work for generating commercial power because it takes more energy to run than it produces. But he has succeeded in creating a “star in a jar,” a tiny flash of hot plasma. “The temperature of the plasma is around 200 million degrees,” Olson says modestly, “several times hotter than the core of the sun.”
Robert Bussard, a nuclear physicist who has spent most of his career investigating fusion for both the government and private companies, applauds Olson’s ambition. “These kids are studying much more useful physics than what the country is spending billions on,” he says. “It causes them to think. They’re not going down the mainstream path to oblivion.” And, aside from using high voltage and emitting low-level radiation, the machine has been deemed harmless. “About a week ago, the department of health from Michigan called my principal,” Olson says. “They wanted to come over and inspect it. They did that, they were impressed, and it checked out.”

Cool :thumbsup:

there's a kid over here who at 13 is making biodiesel in his shed.

farmer's son, never did well at school but got interested in biodiesel, built (yes, built) his own mini-refinery and produces all the biodiesel to power his dad's farm equipment. he's the youngest person in the UK to hold a waste carrier's licence.

I read the same article (with slightly different wording) in this month's Popular Science.

I also found the article about recharging batteries wirelessly through radio waves quite interesting, as I've used a similar concept in one of my sci-fi writings...and now it's reality. I feel kinda like Gene Roddenberry.

Heard of the batteries you pee on to recharge? Now that's cool.

Thanks for the article. Man, I can't wait for the future.
