The only stipulation would be in the design of the hydrogen fuel cell. Simply put, a nondescript “closed loop” system that would need to be developed to make all available hydrogen and oxygen consumed at the least amount possible during normal usage.

I am only stating what ‘could be’ but not yet assembled in the way that I am describing here. All of the mentioned technologies exist today meaning the solar panels and hydrogen fuel cells.

But so far I have not heard of anyone assembling them in the way I describe here.

The “closed loop” approach means that the exhaust from the hydrogen fuel cell is vapor, mist and water then directed into a “closed loop” system via a hydrogen separator putting the hydrogen into one tank and the oxygen sent to another tank for its storage. Both of the tanks would be monitored through recharging ports on the top of the tanks. This recharging port is only needed when the hydrogen and/or oxygen gets depleted during normal generation process and at membrane changing time when some is incidentally released in minute quantities.

If this were indeed possible just imagine how much improved everyones lives would be. Use the fuel cell with the “closed loop” system alone to power automobiles and even trucks when this technology is put together efficiently. Then all fossil fuels would no longer be needed for transportation.

All that I can add is, this is only possible if some individual(s) much smarter than I can to solve the process in an energy efficient way and to then apply it to the package as an end product.
