Note the bulge just behind the leading front edge. On another post that I cant find I believe the bulge alone increased fuel economy 5% at highway speed.
Have you thought about heat storage? Just storing hot coolant in a hot water heater for warming the air or heating water for sink or shower use.
Solar is another one. Lots of room on the roof for solar.
