Re: Tyler's Demo Fusor

Your fusor goes out because your vacuum system is doing better than 25 microns so there isn't enough gas in the chamber ... the pressure (say, 30 microns) so your plasma stays light. Good you are wearing safety glasses but that doesn't protect your face. A thin walled glass like that is ...
