Paul Wheaton talks with Steve Heckeroth, who has made an electric tractor. Paul shares about his electric golf cart, which he used for a lot around the farm. Steve talks about the energy that goes into food production (moreso than its transportation). Steve uses DC motors. They talk about traction. Steve talks about using an 80 lb battery in the front rather than buying weights. Steve talks about the Scratchbuilt tractor, (Number 7) which also collects solar energy. He talks about making farming easier by not having to look backwards while driving. There are several positions you can sit in. The tractor is directed by a joystick, which can stick in place, and can go so slow that you can't see it moving. This is great for going back to the back seat on the ground to plant flats or harvest as you creep along. The tractor is very quiet, and can turn on and off easily. They talk about using vegetable oil in hydraulics. The tractor also has a camera and can be remote control operated. Steve talks about minesweep tractors that would explode landmines in post-war areas. They compare Steve's tractors and their efficiency to traditional 45 horsepower tractors. Steve talks about linear actuators. Steve talks about regen, putting energy back into your batteries when you brake. They talk about in-wheel motors. You don't need a clultch in an electric vehicle.
