Has anyone any experience with Hydrogen as a heat source? There are a few DIY water powered hydrogen furnaces out there but very little info. Anyone?

every example of hydrogen from water I've ever seen was a case of it would be better to just heat directly with the electricity used to split the water.

I just saw this, and noted that I did not respond to Item #51 (just saw that also...)
So 1st off, apologies to George for the math (altho' I did not realize I had actually used any...) Regarding the potential effect of pulling a partial vacuum in (presumably) twinwall acrylate, I found this link on the subject: https://forums.energymatters.com.au/alternative-building/topic2411.html
"A vacuum certainly cuts the heat transfer via conductance down, but not radiation... sunlight makes it all the way here through 150million km of vacuum! In any case, air is quite a poor conductor anyway". Given the scant amount of data on the subject, George, I suspect that the only way to answer your question would be to run a side-by-side test with two identical specimens of glazing, one under partial vacuum, and one at atmospheric pressure, and compare the results.
