  1. iron/zinc-air (sheet steel) water-ethanol koh with carbon felt air electrode fuel cell works nicely at 1.25V per cell, full energy storage rating of about 2kWh/kg, if you like silent electric but better batteries = fuel cells, just make sure you have electrolyte (ethanol-water koh) in the cell and fresh metal, then it will run, does not generate hydrogen, needs air access from outside the cell, so an air mesh or using the carbon felt as air filter works, carbon felt can be also carbon fiber cloth, no epoxy

  2. aluminium has 8kwh/kg energy storage rating, so it would be 2kg of that stuff, to get the same single use fuel cell, which can be refilled with new koh-water electrolyte and metal, iron/aluminium/magnesium 2-8kwh/kg

  3. yep same energy storage as gasoline

  4. use carbon felt (carbon fiber felt/sheet) as the air electrode
