Geothermal Heating
Malcolm Gladwell writes on his blog about a way to heat your house called geothermal heating. His dad saves $2,000 a year and keeps 16,000 pounds of CO2 out of the atmosphere by using the ground to heat his house.
If you're an early adopter looking for a way to put green energy in your home, this isn't a bad place to start.
You should read the june edition of Pop science it has hella new green energy advances. That is where the pic u posted is from.
My neighbor just used this technology to build his house. Their heating bills are a fraction of mine!
