Re: RMR-Farnsworth Fusor 5

I agree. VERY impressive setup! Though from the images of your grid, might need to use something a bit more durable to thermal stress as the grid shape looks to be distorted when in operation. Other than that, everything is very well done.

Re: holmlids fusion with rydberg deuterium

I'd say based on the very short pdf that this is not fusion but laser induced fission in a high density fissile material (i.e. Deuterium).

Just my two cents.

Re: What is the quality of 304 stainless steel that makes it so preferable to fusioneer?

Also, you can look into lead glass instead of standard plate glass to reduce x-ray emissions from the viewport. That's just my 2 cents but everything the others have mentioned are all very good and valid items for you to take into consideration.

Looks much like the Polywell structure. Might be what he got the idea from... yet another Farnsworth design.

Re: The Neutristor

Too bad the smallest neutron generator is natural elements and I'd have to see schematics of that little device before I'd agree to any validity over it even if it's from Sandia.

Re: Fusion-Fission Hybrid... A break-even fusor?

Sub-critical fusion means it won't go nuclear but still runs the risk of meltdown and creating a gaint hole in the ground.

Re: Nuclear battery charging via Fusor?

One nuclear method is an array of nuclear pellets, the same that is used to power satellites, to charge battery banks along with solar and wind power generators. Just my two cents.

Re: Why *is* fusion research so slow?

<t>Unfortunately, for a star to work, it needs both fusion and fission of many different elements to keep going even at the loss of mass ratio our sun has. Still a bleeding/burning-off fuel approach but it gets easier the bigger scale you go. I believe this is why we can't achieve anything like the ...

Re: Archived - Fusor progress, info & photos

<t>Scott, I can definitely see the improvements in the welding process in these photos and glad the process was learned and refined through trial and error. This set of photos shows a very high quality and clean set of welds and would gladly pay for this quality of work myself. I apologize for the b...

Re: Archived - Fusor progress, info & photos

<t>I'm also a welder and I'd have you go back to school before anyone would even remotely be able to purchase the items. The lines are horrible, too much heat, too much beading. These are amateurish mistakes from an apprentice and not a journeyman, craftsman or mastercraftsman's work.<br/> <br/> You...
