A retrofit with hydrogen is something we could work towards. That's a priority, same with creating our own electricity. These dreams and thoughts have marinated with me since I was 16. Currently what I want to build is salt water batteries, make a large pack in the garage, charge with solar and wind surrree but realistically, I have this military generation 5kw. It needs some tlc, I say we get it running with gas first, then get it going on hydrogen! Charge up the batteries from well water?! Yes please.. as far as our vehicles.. We will have to take the engines apart and replace the valve seats, valves, valve springs, with titanium material so they don't burn up. Hydrogen burns clean but also hotter! All these details don't really come out until you get obsessed with the lifestyle like me. I'm actually just injured right now, healing up. Sciatica. Keep lifting everything by myself. I'm no where near where I want to be, maybe I've been waiting for you
