The Tesla Powerwall...Prepping on steroids...

This is big news in the prepping community.  I don't quite get it, but many are excited by the possibilities and see it as a way to finally get 99% off grid and even to make money selling electricity back if you have a robust enough solar grid system.

Time will tell.

UPDATE:  OK.  I see it now.  We're looking at the first real disruptive technology since the internet.  This is huge!  Hopefully the US military and the Marine Corps in particular will be all over this for expeditionary operations.
