Freshman's nuclear fusion reactor has USU physics faculty in awe
deseretnews.com ^ | 9-16-03 | Alan Edwards

Posted on 09/17/2003 8:18:21 PM PDT by wafflehouse

LOGAN — A widespread belief among physicists nowadays is that modern science requires squadrons of scientists and wildly expensive equipment.
    Craig Wallace and Philo T. Farnsworth are putting the lie to all that.
    Wallace, a baby-faced tennis player fresh out of Spanish Fork High School, had almost the entire physics faculty of Utah State University hovering (and arguing) over an apparatus he had cobbled together from parts salvaged from junk yards and charity drops.
    The apparatus is nothing less than the sine qua non of modern science: a nuclear fusion reactor, based on the plans of Utah's own Philo Farnsworth, the inventor of television.
    The reactor sat on a table with an attached vacuum pump wheezing away. A television monitor showed what was inside: a glowing ball of gas surrounded by a metal helix.
    The ball is, literally, a small sun, where an electric field forces deuteron ions (a form of hydrogen) to gather, bang together and occasionally fuse, spitting out a neutron each time fusion occurs.
    "Here I am with this thing here," Wallace mused, looking at his surroundings. "Who'da thought?"
    Wallace and Farnsworth are much alike. Both are (or were — Farnsworth died in 1971) tinkerers. While Wallace was in grade school, his mother got a flat tire while he was riding with her. He fixed it. For his part, Farnsworth began improvising electric motors at a young age. Both went on to bigger and better things.
    "He was never motivated to take science," said Wallace's father, Allen Wallace. "It was really the tinkering that motivated him."
    When Craig was a sophomore in high school, browsing the Internet he discovered that Farnsworth had come up with a way to create deuteron ion plasma, a prerequisite to fusion.
    While it was not good for production of energy (the source of much embarrassment to the University of Utah in the cold fusion debacle in the late 1980s), Farnsworth's design did emit neutrons, a useful tool for commercial applications and scientific experimentation.
    "He (Farnsworth) was after the Holy Grail of excess energy, but everyone agrees that it's mostly useful as a neutron generator," Allen Wallace said.
    About 30 such devices exist around the country, owned by such entities as Los Alamos National Laboratories, NASA and universities. ("I bet I'm the only high school student that has one," Craig Wallace said.)
    Looking at Farnsworth's plans for the first time, Craig and his father both had the same thought: Now there's a science project.
    They set to work. They found a neutron detector in an Idaho Falls scrap metal yard. Craig built a neutron modulator (which slows down the emitted neutrons so they can be detected) out of a few hundred spare CDs. They found a broken turbo molecular pump lying forgotten at Deseret Industries.
    Too poor to buy pricey deuterium gas, Craig bought a container of deuterium oxide, or heavy water, for 20 bucks and came up with a way to make it a gas and get rid of the accompanying oxygen by passing it over heated magnesium filings.
    Not bad for a backyard amateur who considered himself more mechanic than scientist.
    "I teased him that he was now officially a science geek," Allen Wallace said.
    One professor Friday stood nervously away from Wallace's reactor — which is notably free from any shielding — but he needn't have worried: Wallace's detector measures 36 neutrons per minute just in background radiation from space, and the device's usual output adds only four neutrons per minute. People in airplanes absorb much more than that.
    It took two years of gathering materials and six months of assembly, but the final product actually, incongruously, works.
    "(This was) the day I achieved a Poisser plasma reaction," Wallace wrote next to a picture of the glowing ball. "Probably the coolest thing I have ever seen."
    Others thought it was cool, too. Wallace began winning contests — local, state, national — culminating in second place in the International Intel Science and Engineering Fair last May in Cleveland. He's now beginning work on a USU physics degree.
    "The whole thing combines chemistry, engineering, physics," he said. "Put them all together and you come out with something pretty sweet."
    Farnsworth would have been proud.

Utah's own Philo Farnsworth, the inventor of television.

John Logie Baird -- 1888-1946 is considered the original inventor of televison (albeit a different technology than the all electronic tube)

Inside joke?

I wonder if that scrap yard had a calendar with naughty pictures of Madame Curie on the wall.

What else? A perpetual motion machine. It will be on the market just as soon as the Feds can determine it's life cycle by testing.

I wouldn't take this article too serious until someone with a physics degree from somewhere other than Utah certifies it as credible. Smells of really bad science to me.

It's pretty credible to me: Here's the relevent part: Wallace's detector measures 36 neutrons per minute just in background radiation from space, and the device's usual output adds only four neutrons per minute. People in airplanes absorb much more than that.

In other words, the machine produces an output of neutrons that is barely over 10% of background levels. One neutron every 15 seconds is, well, not very many. "Notably absent is shielding," the article says elsewhere.

In contrast, if the cold fusion experiments were generating the heat they were said to generate from fusion, Pons and Fleischmann would have been promptly killed from all the neutrons that would have had to have been generated. Many, many orders of magnitude different.

Wrong. Cold fusion does not give neutrons.

At the recent MIT demonstration of cold fusion, FReepers were present,
and several presented, including a demo.

You might download some recent papers and get up-to-date.

some update here for FReepers interested in CF

Well, the guy who invented the thing died in 1971, so it is hardly new ground. While it is mildly impressive that a high school kid built it, the machine itself is rather simple to be terribly impressed by its construction: the vaccuum pump connected to it is more complex and harder to build.

And it sounds like he is operating it at a ridiculously low energy level, albeit enough to demonstrate the principle.

First place doesn't exist. Do not talk of this.

thus the need for the TV camera to see the plasma

And a plasma screen to view it, of course!

Sweet! I remember reading about Philo and his fusion dreams on the Internet, and filed it away in my head as one of those things I would try to build some day. Its great that a guy this young would do it! He could be our new Edison.

The thing has been crawled over by all manner of scientists- it's safe.
The reporter is a dolt though:"It took two years of gathering materials and six months of assembly, but the final product actually, incongruously, works." After all that work and effort put in by a real bright kid, it was supposed to fail? Maroon!

I disagree. I have attended a talk presented by Fleischman himself at Caltech, and I'm sorry to say he has gone off the deep end - though his talk was entitled "new developments in cold fusion" there wasn't any new developments presented, and the data he did present was unscientific and full of holes. I have not seen any evidence of cold fusion - and that said, I would like very much for it to be true.

Madame Curie was a female scientist from the early 20th century who made many discovries dealing with radiation. I believe they named an element after her. Curium?
