No thanks
I already have a 3 point hitch 7000 watt generator for my either one of my diesel tractors, a 1500 watt inverter I can use on the other tractor, a 5000 watt gas generator, and a number of smaller inverters. At least I am honest about my emissions, unlike the EV crowd. With over half the electricity produced by coal in this country where do they think their power for their back up batteries come from? Transmission loss on the power lines adds to the carbon footprint of this scheme. Now, a Prius, used with an inverter would be OK, as it's power is locally generated compared to the Leaf. I have about $1500 invested in my back up power systems and I can use them anywhere. After the ice storm of Dec 09 it pays to be prepared.
