[AT] OT: Gas story - now thermo

[John Hall]

Been following bits and pieces myself--seems to be an interesting concept. I 
remeber several years I read in a farming magazine, someone had built a new 
shop and buried PVC pipe under the floor to use for heating. Wherever they 
were, the winters were real cold and a constant supply of 50 deg air made 
the shop rather toasty.
