back of the envelope

6 A x 75 V = 450 W

6 hr recharge = 2.7 kWh , went 8 miles

I pay $0.10 / kWh,

$0.27 for the trip, or 3.4 cents per mile.


(NOW...compare to my V8 engine....)

13 miles per gallon petrol

$3.75 per gallon petrol

29 cents per mile.


It looks like I'm getting 8.5 times the bang for my buck!
