Re: New Fusor - Prototype Test

... the electrode for the anode is too close to the glass cover. At high voltages (15 - 20 kV, 30 - 50 ma), metal sputters onto the glass, and then, ... a powerful fan to blow air onto the x-former. These upgrades add to safety and, hopefully, reliability. I am rather pleased by my central 'electrode'. ...

Fusor Power Supply - Initial Plasma test

... up the power supply (PS) This all worked very well. The current and voltage are controlled by two principle parameters - fusor pressure (which ... upper voltage value, of course, should never be exceeded for x-former safety issues.) Will see if running 30/35 ma at the highest voltage is worth ...

Re: Water as Neutron Shield

First, water around high voltage is safe but paraffin isn't because in the event of fire, it can burn? Sorry, ... doubt, the number one hazard I see with a fusor or a sim-fusor. Also, exactly what safety regulations are there for the average home fusor? Are you serious or forget this ...
