Re: Earth-tech fusor from 1999

This is a very interesting description of this early fusor. Something I’ve not seen before was his use of the secondary of a neon transformer as a high voltage inductive filter.

The paper you list is a 2005 report by Taleyarkhan and others. The Purdue investigation which found him guilty of misconduct was in 2008. The sonoluminescence effect is real; one can see that, but I’m not aware of any substantiating evidence for sonofusion.

Re: SonoFusion Setup

It is my understanding that the claims of sonofusion have been found to be false. An investigation of Taleyarkhan at Purdue found him guilty of research misconduct and his funding agency (Office of Naval Research) barred him from further funding. Is there something more recent that suggests this can...

Best way to stay alive is to not take unproven remedies. I think the moderators need to initiate a new rule that the site not be used to promote any medical treatments.

Re: Vinyl tubes and j b weld

Vac-Torr is a high vacuum epoxy seal that is designed for high vacuum use. There is a less expensive Loctite product that is an equivalent formulation, but the number escapes me at the moment. Anyone else remember?

Dennis, I am able to get the WSJ article by just clicking on the Apple news link, and I don’t have a WSJ subscription. I don’t know why it won’t work for you. I am not able to get into the WSJ web site directly.

Re: Coronavirus pandemic

Something that has concerned me even more than the current pandemic itself is what it has revealed as a major gap in our national security preparedness.
