Douglas Alpenstock is likely correct here on the zero sum of heat energy expended for steam in HTSE
versus the energy produced by hydrogen then combusted for heat. Concentration of energy is not a
a forgiving principle.

   But if hydrogen production for other usages was the goal and cost could be lower
than for conventional production, that is a definite advantage.  

A quick search finds that high temp steam electrolysis (using electrical input for heat) is more efficient at higher temps because
the heat supplies some of the energy required.
And at 2500C (4532F) no electrical input at all is needed.

The problem becomes one of materials in that steels cannot tolerate elevated temps in this range.

If HDC has discovered anything new to increase wood burning efficiency I would indeed be very surprised.
Moisture in burning firewood is normally heated above 212F and evaporated up the chimney before usable heat is produced.
If HTSE could successfully be done in our woodstove that represents a great efficiency increase since that water is almost always
20% or greater, usually 60% in green wood, and up to 150% according to one source. That's a lot of wasted potential.

The flue gases would be mostly N + CO2 instead of  H2O + N +  CO2...............unless the high temps produced the hazardous  NO pollutant.

      Motorcycles/ 4 wheelers have air cooled engines. I tried it on 4 wheeler with large piece of chain link fence.
Got the job done but engine was hot and stinking. Driving in low gear doesn't work due to slow speed and not
enough air flow to properly cool.  Didn't want to use the heavy tractor which would compacted soil to much for
my liking.  Maybe I'll use the dunebuggy next year...........

I am trying to make no-till seeding work on an acre plot and learn a little more each year.  And yes, seeding cover
crops is the best way to regenerate  and bring worn out dead soil back to life. Having live roots in ground year round
armors, protects and builds topsoil and increases available nutrients due to microbial activity. After cover-cropping
a few years I have healthy green crops of corn and veggies with no synthetic fertilizer input. I do broadcast lime every
few years but that is all. No fertilizer, no manure, just interseed cover crops at corn v5 stage and again in early fall
after harvest.  You'll also notice lots of deer and other wildlife visit to forage on your cover.

I use Ghee in Bulletproof Coffee.
About 1 tablespoon per 12-16 oz coffee.
Also I usually add a little coconut oil, teaspoon cacao, 1/4 tsp stevia powder,
and dash of ceylon cinnamon powder.

Put everything into a blender and add boiling hot coffee.
Blend at least one minute and serve immediately or store in a thermos for later.
