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

First, I see you have read up on many issues relating to these topics. I will address some of your statements and questions. It is good you have such interests and do try to understand some of the topics related to this very complex and frankly, very technical topic (when one trys to get into the fa...

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

Richard, certainly fusion is not available even if all went perfectly for the W-7X or ITER over the next twenty to thirty years. And fusion is not the answer for AGW by any means unless a real proto-type plant is ever built. As for solar, it and wind, as well as the Candu fission reactors could do a...

Re: My progress II

Going from 10 microns to 20 microns in a minute could be normal out gassing from the chamber (i.e. a virtual leak.) Letting the system stay under low pressure ( 4 *10^-4 torr) and heating the chamber should drastically lower that rate. Running a plasma will help as well. Are you using a turbo or dif...

Re: My progress II

Do know that large chambers can create stable plasma's at lower pressures then small chambers; for instance, I could create a good plasma from 3 to 12 microns in my large chamber. When I halved the volume, that pressure for a stable plasma increased to the range of 10 - 24 microns (below 10, the pla...

Re: A Thought Experiment on Ideal Conditions

You have a few mis-understandings and need to learn a bit more on both fusors here (see FAQ's) and read up on the physics of fusion in our Sun. A fusor produces essentially zero (as far as instrumentation for power goes) energy output from fusion. All the heat is created by the power supply so fusio...

Re: Negative Polarity Power Source?

As I posted (had hoped you might have read it), and Mr. Futter said as well, any polarity will work for a demo fusor. That said, if you have diodes, the definition of the cathode and anode are created by connecting the correct polarity to a given part of the fusor. The negative to the cathode; then ...

Re: Hello from Melbourne Florida

Very nice project and demonstration of ions in a voltage potential; I really appreciate the Mars project! I've written a White Paper for NASA on how humans can reach and return from Mars safely.

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

Richard, all things related to controlled fusion is a bit of a calculated crap-shoot. Theory can take one only so far; then the experiment has to be built and tested. Only in the last twenty years has physics advanced enough thanks to all the experiments (and associated failures) to finally get to t...

Re: HV feedthrough & chamber insulation

You could run an other ceramic tube down the HV lead and use a good ceramic compound/glue to locked it in place. I do that but room is always an issue. If that isn't possible your choices are limited: get a new feed-thru, machine the existing one to handle a thicker ceramic cover - if possible, or (...
