Baltimore Bridge Disaster

Yesterday I learned that a 280 million tonne cargo ship lost power and crashed into Baltimore Bridge causing it to topple into the sea. Baltimore is a large port city in-between Washington and Virginia. It is the American equivalent to Portsmouth here in Britain. 

You can't stop a 280 million tonne cargo ship without engine power or significant distance unfortunately. It was just before I learned of the Baltimore Bridge Crash that I was thinking about EVs. 

Many electric cars can store more than 35 KWH(kilowatt-hours), my home uses about 5 KWH every day so electric car batteries could power my home for a whole week or more; to me that is astonishing, I never imagined they would make batteries that could store enough energy to power your house for weeks. Perhaps it would be normal to plug cars into a meter and power your house when there is a power cut.
