The battery must be the size of a small house.
Imagine a local fire department trying to put out an “unexpected” conflagration involving one of these contraptions? It’d last for days.
“The battery must be the size of a small house.”
A small dog house.
I calculate a 200KWH pack would only have to be about 5 foot by 6 foot and < 12 inches deep. Also, with new batteries, some cannot even catch fire, of are very hard to catch fire (the fire issue comes from the electrolyte, not the lithium). There are batteries with little to no electrolyte already.
Not only that, “There’s more to prime. A truckload more”. A truckload of cinders.
But the trailer is so battery heavy it can only carry 2,000 lbs of freight.
