Re: Joe Gayo's lab tour

Half of the D-D fusion that happens should be producing T + p. The other half is producing He3 + n. Some of the T that gets produced may also get burned. So you should see some 14Mev neutrons coming out if you are actually burning DT. Probably most of the T is getting buried in the walls of your fus...

Re: Demo fusor build 2.0

You might consider putting a piece of sacrificial glass inside the chamber in front of your very nice large viewport. So that if you get a jet that ends up pointing at the viewport you don't end up cracking it and ruining it. You wouldn't be the first to lose one due to localized heating from a jet....

Re: web site problem

I would like to second Andrew's request to enable the active topics button when not logged in. I have been using this site for many years, and never logged in, except when I decided to make a post. Which was infrequently. It was very nice to be able to track what was going on, without having to logi...

Re: Commentary on Doing Fusion

I think that removing reference to age in the neutron club list, and ending the tracking of whoever is the youngest to do fusion, is a good idea. I would support scrubbing the current list of all references to age, and to "youngest" fusioneer. I think that the bar for accepting folks into the neutro...

Re: Commentary on Doing Fusion

I think that realistically the best criteria for entering the neutron club, is the one we have already. Arbitrarily stating that you can't be a member of the neutron club, because of your age, despite the fact that you can prove you have made neutrons, doesn't seem to me like the right thing for us ...

Re: Dumping the trash

I also had an idea about the real name user name problem that so many folks seem to have trouble with. What if as part of registration, we have a single stand alone page where we explain that real name usage on the site is required, and ask for folks first, middle and last names, and require that fi...

Re: Dumping the trash

Perhaps we could have a FAQ about how to register for the forum, and put the answer in that FAQ. That way folks who read the FAQ can get in, and those who aren't even willing to do that are blocked. Probably would be sufficient to keep the spam bots out, even though the answer is in the FAQ. Then pe...

Re: Maybe someone can help?

Yes, but there is nothing wrong with being nice about letting folks know about the real name username rule. When people get jumped on after their first post, they feel bad, and may leave. And that is unfortunate. It is not good for them, and we lose a potential contributor. Which I don't think is th...

Re: Wendelstein 7-X has successfully finished its second major experimental run

Wind and solar are currently VERY cost competitive with fossil based power plants. Which means that as long as that calculus does not change, the day will inevitably come when the vast majority of electricity generated on this planet will be from renewable sources. The way capitalism works, guarante...

Re: Plasma at Last!

You might consider inserting a sacrificial piece of glass in front of your viewport on the inside of the chamber. So that you can protect it from an electron or ion beam hitting it, and causing local heating and failure of the glass in the viewport. Viewports can get pricey, so protecting them is a ...
