$MVTG, feast your eyes on this one please. A home garage stored MVTG-ERC could use sunlight during the day to convert the waste potassium carbonate from the prior day into potassium formate. When the owner gets home from work, he connects a dual line to the vehicle, and formate is automatically pumped into the vehicle fuel tank, and carbonate from the vehicle's tank #2 flows back to the Garage ERC storage #2 tank for processing, conversion back to formate the next day during the daylight hours. Thus the home owner could use roof top solar panels to recycle his fuel cell vehicle waste to make the next days fuel.
