Tesla's battery is a great innovation. The other day when I was passing by a farmer's field and saw the pollutants coming out of his tractor, I said that the Tesla battery could power that tractor/combine easily. Would save the farmer a heck of a lot of money. Once the gigafactory is built, and battery supply is not a constraint for making its cars, I wonder if Tesla will explore other uses for its batteries. Of course John Deere, Catapillar , would have to want their future models to be electric. (Telsa would just supply the battery pack/inverter). Could be a win-win for everyone. Until then, enjoy driving your Tesla !
