We just electrified a 1975 Mazda Bongo by replacing its engine and fuel tank with batteries, inverter motor etc from a 2012 Nissan Leaf. Rippletech is producing controllers designed for just his kind of project. They have already been used to control Nissan Leaf motors in a six-seater Yamaha buggy, a 1974 electric coffee roaster (most roasters are gas) and a hybrid pontoon boat. You can read more about the Mazda Bongo conversion here.

What would be very cool to see is parts from wrecked or end of life electric cars - both battery and inverter - used for photovoltaic installations. There are some one-off installations but a commercial offering would be a great combination of resources: sun, cars, brains. Thanks for all your efforts.
