We're doomed, Patrick. Doomed I tell you.

I love it - a physicist named Putterman.

Cold fusion and "failed to replicate." Seen it before.

The key theorist behind the 'tiny bubbles' approach to tabletop fusion:

You know I always suspected that percolated coffee provided more energy.

[AFreeBird]

[lepton]

Another obvious problem is that even if fusion does occur, how do you get substantial energy out past the fluid that is sonoluminescing? Sure the fluid itself can transfer the energy, but while it is doing that, it is largely no longer available for the reaction.

[Turbopilot]

You forgot a picture of the experiment...

There's been a flood of FReepers joining the FT ping list lately and it's quite likely that I've missed a few, especially if the request was posted on a thread instead of FReepmailed. So, I just wanted to mention that if anyone's requested to join and hasn't been added it's definitely just that I didn't see the request (it's happened a couple times that I know of). Please feel free to request again!

This public service announcement will run for about ten pings or until whenever I get bored posting it. :)

The fact that Nature touched this one sparks my interest. Has to have a net gain before it's groundbreaking, though. Whoever pulls that one off will probably be remembered as one of the greatest scientists.

[RightWhale]

This one is a lot closer to reality than the Pons-Fleishman experiment. Still, it would be next to impossible to get more energy out than is put in because of the nature of the acoustic mechanism. It might produce some useful physics, perhaps a few papers, maybe a PhD sometime.

[adorno]

'sonofusion"? "sonoluminescence"?

Sonovabitch! Here we go again!

[Boundless]

Perhaps the most amusing, and telling aspect of the heady
Pons-Fleishman days was that the proponents were reportedly
running their tests with no provision for shielding from any
likely radiation from the supposed reactions, whereas the
skeptics trying to duplicate were using shielding just in
case they were mistaken.

Had P-F been correct, we'd likely now have "too cheap to
meter" energy, and a bunch of dead champions of same.

[Blast a liquid with waves of ultrasound and tiny bubbles of gas are created, which release a burst of heat and light when they implode. The core of the bubble reaches 15,000° C]


This is not a rehash of that cold fusion baloney.

But creating localized very high temperatures is relatively easy to do if you only want to create microscopic amounts of fusion reactions. The difficult part is using the fusion to make significant amounts of heat in a controlled process that can be used to generate electricity.

[punster]

If they do achieve fusion, an expected result would be an intense neutron radiation field (as well as gamma radiation).

The fusion reaction between two deuterium atoms is:

D + D yields Helium-3 plus a neutron and gamma radiation

I thought this thread was going to have something to do with intel chips inside Macs now.

[RockinRight]

It's already been invented...I've seen it!
