A person could heat a hot tub with a Biochar+Energy System and make money doing it...

In case you just sneezed "horsesh!t" under your breath, heating 200 gallons of water with a temperature rise of 55 degrees F using a biochar making heater would consume about a dollar's worth of pellets and make about four dollars worth of biochar.

It would also sequester some 15 pounds of atmospheric CO2, if you put it in your garden.
