The heat exchanger has been installed in the fuel tank, the T’s installed in the coolant lines, the tank has been painted and it’s time to reinstall the tank.
Professionally, I'm an IT Engineer (Executive Level) and Electronics Tech. Philosophically, I'm a Green Conservative, and probably would have been a hippie in the 60's if I had been old enough. I live off grid, with Solar (PV), Wind, and veggie oil fueled diesel generator power, and have been teaching and living sustainable technology for over 10 years.
