Is the Farnsworth Fusor the Next Big Breakthrough in Nuclear Fusion Technology?

  • Thread starter thed
  • Start date
In summary, a nuclear fusion reactor based on the plans of Philo Farnsworth has been built, but it is not a revolutionary invention and there have been other similar devices in the past. It relies on electrostatics and produces neutrons, but it does not achieve breakeven. Fusion has been achieved numerous times, but not in a controlled fashion. This reactor is not a major breakthrough in fusion research.

[SOLVED] Farnsworth Fusior been built

http://deseretnews.com/dn/view/0,1249,510054502,00.html

"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"

Am I the only one thinking this lad will be making the Cheddite Drive next.

Overhyped anyone?

It doesn't produce extra energy from what I see. And it says others exist. He just had the time and parts to put one together based off of designs.

Despite mutterings about "a hoax" on the web, there is nothing particularly revolutionary about Wallace's little reactor, which has won prizes from science fairs and the like. Reportedly cobbled together from parts salvaged from junkyards and charity shops, the device is the latest example of what is known as an inertial electrostatic confinement fusion reactor. About the size of footballs, they were first designed and built in the 1950s but their feeble power output has seen them relegated to the fringes of fusion research ever since.

Wallace's device instead relies on electrostatics to force the ions together in the centre of the reactor, which means far fewer collisions occur and so much less heat is produced. It does, however, produce neutrons, which show that fusion is taking place

That's odd though, I sometimes hear people talking about when are we going to achieve fusion and it's long since been done just not to a commercial level yet. I thought the earliest was in 1990 or so, but then why all the confusion with fusion? I guess it is one of those things, I mean if any good experimentalist could get on the internet and find the plans on how to build some very interesting devices then scrap it together... who knows what people might do with them or build, my bet is that the most coveted and guarded knowledge of all time is physics, probably for the best anyway.

...although my sources of information in the past were poor and of magazine varieties, probably why most people never heard of it, that it's more profitable to hear of it as some great barrier in science that is being worked on and near a breakthough than it can be done just not very well yet.

Sure fusion has been achieved many times, going back to the 1950s. What hasn't ever been achieved is breakeven. The fusion device putting out more energy than is put into it. The "Farnsworth Fusor" won't come close to doing that either.

(And in a controlled fashion.)

So true. See thread on hydrogen bomb.
 

1. How does the Farnsworth Fusor work?

The Farnsworth Fusor works by using an electric field to accelerate ions towards a central point, where they collide and fuse together. This process is known as inertial electrostatic confinement, and it allows for the fusion of atoms without the need for extreme temperatures and pressures.

2. What are the potential applications of the Farnsworth Fusor?

The Farnsworth Fusor has potential applications in energy production, as it produces fusion reactions that release large amounts of energy. It could also be used for medical isotope production, space propulsion, and as a neutron source for research purposes.

3. How does the Farnsworth Fusor differ from other fusion reactors?

The Farnsworth Fusor is different from other fusion reactors in that it uses a simpler design and operates at lower temperatures and pressures. It also does not require a large, expensive magnet to contain the fusion reaction.

4. Has a functional Farnsworth Fusor been built?

Yes, a functional Farnsworth Fusor has been built and tested by scientist Philo T. Farnsworth in the late 1960s. However, it has not yet been able to achieve a self-sustaining fusion reaction, which is necessary for practical energy production.

5. What are the current challenges in building a working Farnsworth Fusor?

The main challenge in building a working Farnsworth Fusor is achieving a self-sustaining fusion reaction. This requires precise control of the ions and electrons within the device, as well as finding ways to reduce energy loss and increase efficiency. Another challenge is finding suitable materials that can withstand the high temperatures and radiation produced by the fusion reaction.
