luisWinthorpIII, you say you are knowledgeable about the area of technology, so I will ask you the same question I've asked the company several times. What I want to know is how useful the Zinc8 battery would be when the power grid is down. Could you power your home directly from it, or is some sort of converter (like DC to AC) needed? If a converter would be needed, would that be a significant additional expense? When I asked the company all they say is that you need to have an energy source to charge the battery. (To be fair, I don't think I asked the question very clearly.) The main scenario I have in mind is a back up source of power for the home when the grid is down.
