Kinda like the LHC, eh? :-)


That’s probably the healthiest attitude for all non-participants.

Faith, hope and charity (funding) are to be encouraged from investors  
(BTDT) but have no place in the lab. We would not have made useful  
progress if we deceived ourselves.

I’m still curious about this recommendation – in your garage-lab, with a  
similarly (un)funded experiment, what liquid coolant would you use to so  
capture all the heat from a 1400˚C / 2552˚F reactor for a “credible”  
32-day test?

Here’s what the rest of us are stuck with:

Start where you are. Use what you have. Do what you can.

Visit a Maker lab and see how sophisticated some people's home  
experimenting can be. High-tech surplus is cheap but you need the  
knowledge to be able to recognise the good stuff.

Molten beer can aluminum or table salt would do for coolant, IF you  
make the chamber from a metal that can hold pressure at that  
jet-engine-turbine temperature, or separate the heat from the  
pressure.

"The LS-VHTR has many attractive features, including: the ability to  
work at very high temperatures (the boiling point of most molten salts  
being considered are >1400 ?C); ..."

Indium melts at only 156.6C and boils way up at 2072C.

For a low-budget home experiment you'd likely be limited to 316L  
stainless for the pressure vessel, with carbon fiber insulation inside  
it and a silicon carbide reaction vessel. My 316L is scrap plumbing  
from a brewery, my carbon fiber came from a vacuum furnace maker's  
junk bin and foundry suppliers have silicon carbide, though I went  
with clay-graphite.

Carbon fiber conducts electricity so you'd need Kaowool etc around the  
Kanthal electric heaters.

1400C is a little too high for inexpensive Type K thermocouples, which  
top out at 1250C for long-term use, though they survive being fused  
together with an acetylene torch to form the junction without scaling  
very much.

I don't recall 1400C being part of the spec when you wanted a reaction  
vessel built. I personally have nothing better than Titanium and  
Inconel 600 in my collection anyway.

It’s still not. My interest has been in the neighborhood of 400˚C, and  
in verifying that the reaction can be controlled and self-sustaining.

I have no interest in commercializing/licensing these things and have  
turned down (with sincere thanks) the only offer of financial help  
received ($
00 from a Czech software developer).

My only interest is in having an adequate heat source to power a  
no-moving-parts generator – and the plan is to publish everything needed  
to produce a tiny 5-10 kW generator so that anyone anywhere will be able  
to make/buy/sell/use them.

If/when I get there, I probably won’t bother with measuring the thermal  
output because the only thing that’ll matter to anyone is that it’s  
adequate.

At the moment, it’s the generator that’s looking difficult – but that’s  
only because my studies were directed elsewhere. :-)
