I care about the batteries. Because if they're real, which if I remember right you don't think they are, and BioSolar starts making sales from them then this stock has the chance to soar.
Being in two verticals of the alternative energy game is not a bad thing. Just because they are working on Hydrogen (through a subsidiary company mind you), does not mean that they CAN'T do batteries as well. That is like saying if they are doing batteries, they can't do storage.
Tell that to Elon Musk.
