The concept of using a compost pile to heat water is often
attributed to Jean Pain of Switzerland:<br>

I think "hot" composting has been known about for a long time too.
Which of course doesn't exclude independent rediscovery.<br>

<p class="MsoNormal"><span style="mso-fareast-language:EN-US">I
was attending a barn fire near my home in Cherrywood,
Ontario about 1971 or so, and as my step-father had an
aqualung, I took it over. The barn was so full of pyrolysis
gases from the auto-ignited hay (haylage, they called it)
that it was becoming impossible to fight the fire. There
was serious danger of suffocation if anyone tried to “open
the barn” higher up because it would take time. Clearing
the fire required removing the pyrolyzing material by hand
with pitchforks as the community members could toss it to
the front end loader.

<p class="MsoNormal"><span style="mso-fareast-language:EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="mso-fareast-language:EN-US">I
used the aqualung to enter the building and walk over the
top of the hay though the gases (which really stung the eyes
I might add) and kicked out a board at the end of the barn
creating a ventilation hole. Air then entered the working
space and the pyrolysis gases left the building through one
end.<o:p></o:p></span></p>

<p class="MsoNormal">Later, a farmer in Saskatchewan worked out
how to get his manure pile to “cook” and by passing a coil of
water-filled pipe under it, or buried in it, he heated his
house for a whole winter. So the challenge is not to prevent
“self-cooking” but to control it in a useful manner.<o:p></o:p></p>
