Doo already has a proto type electric sled they are working with. I would guess other mfr's have as well. I believe the Doo was shown in one of the mags, not that long ago. Poo was out with a electric UTV 9 years ago. The Poo dealer we work with has sold many. Battery capacity, travel range, is the problem as of now. But the development of "new" high capacity, fast charge, small sized battery tech is going at hyper speed right now. The development process and the time period of this, will surprise us all imo. Solar panels/reflectors are on the same high speed development course in size, and efficiency. Electric vehicles of all kinds are on the way. Telsa has a semi tractor on the road already, and orders for many. UPS has electric vehicles in use now. Don't blink, and stay tuned in!!!
