A carpenter friend who lives three hours NORTH of Toronto Ontario had
a problem getting rid of sawdust from his garage workshop.He dug a
large hole,10'by10'by 6' deep and then he lined it with some black
construction plastic.He put about two or three feet of sawdust on
this,and then he layed coiled flexible copper on it with the ends of
the tubing ending above ground.Next came another couple of feet of
sawdust.He wet the whole business down with his garden hose and
covered it with more black plastic and then enough dirt to even out
his yard again.He knew only that the sawdust was definitely gone and
that he might get some hot water for awhile.Turned out that he heated
his water,for three teenagers,wife,self,dogs,many summer and winter
visitors for the nextsix years that I knew him.Could have lasted
longer,I don`t know.He would bring it up because his sawdust problem
was still a problem.I paid attention because I didn`t think it would
be worth all the digging and it made me nuts struggling to heat water
in my cottage all that time when I could have done the same as him and
got all the sawdust I needed delivered free from him.

Are you sure this is not a
"friend of a friend".
This smells of an Urban legend variety similar to they make lightbulbs
that never burn out.
If something is too good to be true, then it probably is.
Of course, if it is true, give me his name. I have made a huge pile
of sawdust over the last year. Heck, might even grind up a cord of

We need a term for Urban Legends overtaken by time. Such as:
"They" are supressing light bulbs that last for a very long time and use
a lot less electricity. (They're called compact fluorescents, and they
keep getting cheaper.)
"The calls are coming from inside the house!" (From a cell phone, maybe?)
If you get an e-mail with the title "GOOD TIMES", don't open it or you
will get a virus. (At the time this one originated, that was impossible;
isn't progress wonderful?)

My calculator says that if a family of four all take a ten-minute
shower, that'd be only 60L - unless, of course, they shower
If they get the dog into the shower with them, the shower might take
