NATO Secretary General wants solar powered tanks. [rolls eyes]
The comment there sums it up:
The stupid, it burns … an M1 tank gets 0.6 mpg. A gallon of diesel contains ~ 40 kWh of energy. A solar panel puts out ~ 1 kWh per day. A solar panel is about 17 sq. ft. You MIGHT fit four of them on an M1 tank without impairing the weapons and sensors. Then you’d need four Tesla Powerwall batteries, weight half a ton.With that setup, every ten days you could move your tank 0.6 miles …
Here's your sign.
