DailyDirt: Making Fusion Reactors For Fun...

from the urls-we-dig-up dept

Amateur fusion isn't quite a new fad. Online resources have been available since the early 2000s, and plenty of people have learned about or built a Farnsworth-Hirsch fusor for themselves. Philo T. Farnsworth (perhaps more famous for inventing TV) designed equipment that could fusion atoms together. Before anyone gets too excited, though, none of these designs look like they could ever produce any excess energy. It would be nice if fusion generators actually did exist, but we're probably not going to see any in the near future. In the meantime, playing with fusion reactors might inspire a really clever design, so here are a few links on DIY fusion. If you'd like to read more awesome and interesting stuff, check out this unrelated (but not entirely random!) Techdirt post via StumbleUpon.

    I Didnít Believe It Myself, But... turns out a Farnsworth Fusor is an actual real thing you can build at home, without a military-level budget. Heating a few ions to temperatures of millions of degrees is not that hard to do, it just requires an electrical potential of a few thousand volts, which any hobbyist can manage.

    However, the current feeling is that such a device will never get close to giving back as much energy as you have to put into it...

    I believe you mean fission. Viable nuclear fusion is still in the works.

    "the current feeling"

    Very punny.

    No, Fission.

    It's still energy-negative, but it's fissin.

    I've played around a little with the current 'pocket generatoin' (a Farnsworth fusor), and while the 13yo is the youngest one now, that one was built on a design a friend (Chad ramey) made when he was 17 from about $5k in recycled gear, and which is the smallest design available at present.

    Here's some pics from 6 months ago /
