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

I will mention that propane is an excellent heat absober (better than water) and works great as a coolant; while not as hazardous as hydrogen, it is explosive in air (in the right mixture ratio's) so it must be used with extreme care and no leaks can occur. I have built a number of refrigerator syst...

Re: dynamic fusor patent, Salvatore Pais

A few more "words" on the various subjects mentioned here. The start of the universe neither required fusion nor any energy input (that we understand in the slightest) but this certainly say's there is more to the universe than our current physics understanding - in fact, all energy currently or pre...

Re: dynamic fusor patent, Salvatore Pais

Many in the real fusion community are laughing about this - but then, anything can be patented if it is different. A patent does not require anything to work, just not violate laws of physics. I won't worry about this effort enough to even evaluate it any further - zero money will be put into it and...

Re: First ever Turbo experience

I use dry air - that is, room air filtered and sent through dryerite; however, that was only for my high vac system. Frankly, I'd think for a fusor, it wouldn't really matter all that much if one didn't use dry air at all but just filtered air. Then used their fore pump, afterwards, to pump the syst...

Re: First ever Turbo experience

I have the identical type; mine has neither a heater nor those fluid lines that yours does. I use a small fan for cooling and that is more than enough. For operation, I simply get the system down under 100 microns, and use the "Pumping Unit" button to allow the turbo to get to full speed. The "STAND...

The Wendelstein 7-X Stellarator

As I posted a while ago, the 7-X stellarator has meet or exceeded all objectives for its first major campaign (achieve the desired plasma densities that are required for a power plant and maintained for 100 seconds - all records for this type of device.) As such, they have been upgrading it to achie...

Re: Demo fusor progress

Impressive high voltage supply but like a real fusor supply, yours is also very lethal. Also, wood isn't really a very good material to encase high voltage systems - its water content can cause corona issues. Good machine work. Milling is, for me, fun. Lathe's are generally just a hassle.

Re: TurboVac 50 troubleshooting

When you say you switched around controller wires - what!? Turbo's require very specific connections and one can't switch any wires around and get any results. Random acts like that can really damage a turbo/controller! Get the proper wiring or don't do that! Some turbo's monitor current load. If th...

Re: Is this a possible way to generate energy by fusor?

"Both" as in one idea and then followed by the other idea - not a reference to both of you who commented; sure, I think everyone should know the Carnot cycle but realize that is a bridge too far for many. Besides, I seriously doubt most such fantasy based thinker's will ever bother with such crude r...

Re: Is this a possible way to generate energy by fusor?

Read some thermodynamics, first. Specifically, the Carnot cycle. You will both learn a great deal of valuable science and be able to understand when and when not a system can produce useful energy from any energy source that provides heat.
