Re: Non-Corrosive and/or Dielectric Liquid Cooling?

... area, with excellent success. Started with a thermos full, drawn from a BBQ tank so old it still has a POL valve. Glad to be with Dennis on a safety thing! Am reminded of one classic HV high bandwidth scope probe: the Tektronix p6015. They came with freon insulation (dichlorotetrafluroethane), ...

Re: dynamic fusor patent, Salvatore Pais

... Finally back to fusion.....No matter what we do, fusion will require tremendous input energy to force whatever ions we choose to defeat the safety mechanism that nature has put in place to prevent stars from going off like firecrackers in the night sky. This is the electrostatic repulsion ...

Re: First ever Turbo experience

... bearing so no lubricant is required, if the pump is moved or rotated the torque on the rotor will push it to one side. There is a ceramic safety bearing, but it's only there for protection not designed to be spun up; it wares down a little every time it is touched when the rotor is spinning. ...

Brute forcing high voltages with two MOTs (not what you think)

... this very post that I wanted to make over a month ago but the site was going through issues/revisions so I waited. For anyone concerned with my safety, I DO OF COURSE plan on using NMN laminate paper for the insulation between the core and the secondary, use layers of kapton tape to separate ...

1D Cathode with Neutron Run

... how to Pulse Arc Weld, and I am fairly sure he was making a 2D Cathode. Post welding put a brass brush on a dremel and brush the welds shiny. Wear safety goggles or you will lose an eye. Brass dremel brushes release brass shrapnel. Vacuum Chamber: If you are not jealous of my Fusion Mark III chamber, ...

Re: Precipitator HV Supply Hacking

... time with the original voltage control pot. As indicated by others, the added capacitance of the 8’ extension lead could’ve been the culprit. For safety, it’ll be a simple task to add an acrylic extension to the control. Mark Rowley

Re: Fusion Success with Precipitator Power Supply

... the 60). It would be crucial to make sure ones HV feedthrough and leads can withstand the full potential of this type of supply PLUS a healthy safety margin. Although they are comparatively tough, I'm skeptical if they can survive arcing for more than a couple of seconds. Beefing up the HV ...

... (the Spellman has some output capacitance) I raised the voltage first to 20kV and then 30kV as I got the hang of it. As mentioned before the safety features of the Spellman supply can be tricky to handle, and the plasma extinguished numerous times due to over-current and arc protection. I'm ...

Re: [REQUEST] 1 kV 10 A Diode and 10 kV Cable

... a major spike occur, the diode is actually designed to fail and short the HV supply through a high wattage, low ohm (maybe 1 ohm) resistor for safety. This probably needs to be only 20kV, 1A rated in your case. Finally the third diode stack on the transformer secondary (if you go this route) ...
