Firstly, they'll need to drop all mention of bacteria or viruses, if they're gonna sell batteries to idiots. you know for a fact FOX and the UK press are going to run with 'New batteries powered by AIDS, in YOUR children's toys!' I really wish I was exaggerating for comic effect, but I've actually seen Fox, and it makes the Onion look like responsible journalism.
Secondly, yay, if this works, and works in a big enough way to make electric cars a viable option to normal people, maybe we can finally quit pretending wars are about terrorism etc, as we won't be reliant on oil so much.
Although I do wonder how happy the middle east will be if we stop 'interfering' to the extent that we stop throwing billions of dollars at them for oil.
