Summary: We might have something here, maybe.

Summary: We need better batteries.

Summary: We can't make it work in a real world production environment.

Summary: We built yet another battery in the lab that may or may not
be practical.

This is a wonderful thing. It gives promotion. However, they will never 
give reach e=mc², which reveals the equality is just an ad-hock equality, 
out of nowhere.

I mean, they are pushing batteries over batteries nowadays, for gosh sake, 
it's still a stupid battery, no intelligence in it. Reminds me of 
something, which is Relativity. Relativity is like a battery. Simple.
