Interesting topic. One wonders how long before EV manufacturers offer a quality AC inverter and outlet built in as standard equipment.
I was interested in the comments provided along with the video, especially one inquiring about the suitability of a hybrid Prius for emergency power - it evidently is feasible.
My projected requirements for a power outage are fairly minimal - cell phone and lighting. I will keep the fridge closed and eat the ice cream before it melts. Between a couple of solar panels and a small inverter in the car, I should be set. For hot meals, we will haul out the camping gear and fire up the propane stoves, as well as the fireplace,if necessary.
