2011 Continued evangelizing Solar and now Electric Vehicles (see http://aprs.org/EV-misinformation.html


2014 Converted from Heating oil to GroundSource Heatpump and added another 8 kW solar to complete conversion from my 3000 gallon per year fossil fuel addiction down to only about 200 gallons a year (for visiting grandma with the Prius)... See http://aprs.org/geothermal.html  Got my wife's church to go solar, and support EV's: http://aprs.org/AFM-environment.html
