content: The more I dig on these batteries, the more scammy this whole area of research looks. Here's an article on the magic of these batteries from S Korea. They're talking about a new electrolyte too. They have major errors in simple things like comparing energy densities of aluminum air batteries  and gasoline and how far electric cars can go in Wh/km. They’re so far off it’s comical. https://phys.org/news/2018-10-catalyst-high-energy-aluminum-air-batteries.html  I call bullshit on this whole thing.
