looks like eight -12volt for 96volt.
instructable shows 15-20miles, top speed around 70mph.
some of the others use off the shelf motors, some recycle electric forklifts.

I had just wondered if four 36v motors could be run in series with a single controller (dc motor controller and 500k ohm pot).
I had envisioned attaching a small trailer with a dozen car batteries and a charger in it.
Electric forklifts are more expensive than the golf carts are.

I've been looking at chickenwire/shotcrete art form structures as an alternative low cost 'building' method (poured in place slab in an 'igloo' basically) and swimming pools/pond liners. The sprayers typically function similar to a bernouilli venturi pump using 'dry' cement. Has any body out in...
I've been researching this lately (.01$ per mile fuel cost, 2500$ diy cost).
The off the shelf kits are around $2500 plus batteries. They typically are 10 to 15 hp 48v electric motors. Golf cart motors are typically 3 hp 36v to 48v.
I've been wondering if it'd be possible to speed control about...
fyi- lots of em out there- I like this one because it breaks out heat losses

most recent stuf I've read they use radiant floor tubing in raised beds to lower costs. A lot like the water troughs in the inca mountains (heat the soil to keep the...
I've wondered about this (as an outsider) because the thought of using an abandoned underground mine for a solar updraft turbine piqued my curiosity. the turbine would be at the top, solar hot water basically poured down a U tube to the bottom of the mine and convective upward air flow.
