Re: Coronavirus pandemic

Thank you all for these informative posts as well as this thread on this serious illness! This country desperately needs testing kits - unbelievable that the most powerful country in the world can't provide everyone who needs it a test - words are beyond me. The lost months were absolutely critical ...

Re: Update on experiment

Glad your still working towards your goal. That shows commitment; however, with vacuum systems and leaks, one must also accept that there is a reason people use professional chambers, connections and vacuum pumps - saves vast amounts of time and efforts while finally allowing one to reach their desi...

Re: Leak in vacuum system (diffusion pump?)

While excess volume isn't desirable, the real killer for any system is the number and size of connections! This is where 99.9% of all leaks occur. Making good connections isn't always easy and leak checking is essential and not always easy; and even then, very minor leaks can occur (a damaged surfac...

Re: Loads on roads

That liquid hydrogen is so "fluffy" is exactly why it was not used to fuel the first stage of the Saturn V rocket; that used kerosene (and, of course, LOX.) This enabled the Sat V to climb out of the earth's gravity well somewhat faster (due to greater Impulse due to kerosene's far greater density) ...

Re: Fusor V construction - the process long running

Good work! You have my exact same turbo; I say this because after I added turbo bearing oil to my wick, it then took hours of pump down and heating of the unit to get all the water and other stuff out. Maybe your case, maybe not.

Re: Radiation of a Deturium Fusor

Besides what Richard said, to answer your main point - the most significant hazard of any real fusor is electrocution. You get no second chance.

Re: Fusor construction questions

I see you have two possible fusors chambers (a large diameter, and small); nice economy on pumping systems. Very professional system. If the cross is silver, are you trying activation, maybe?

Re: Newbie construction of chamber

I'll save any welcomes for the intro post. That said, the vacuum chamber is the least important part of a fusor; the complete vacuum system is its heart (the chamber is a minor part of that complete system.) Of late, a 50 mm or smaller diameter vacuum connector cross is the best fusor chamber for be...

Re: Fusor construction questions

That method is fine.

One point: Unless you need to access the fusor, keeping it under vacuum (ball valve closed; turbo off) is a good idea. Far less water vapor introduced into the fusor chamber.

Re: The endless quest for safe, easy accessible energy.

Poor Tesla - a very brilliant thinker that lost it after great success. He crossed (stole) from the very wrong and rather evil man (Morgan) and was black-balled for it. Luckily, Morgan didn't take the extra step. Today with google and simple facts people still create far greater crazy conspiracy the...
