890g for energy system for 45Wh
Lipo pack = ~700g for 90Wh or 72Wh everyday usuable, ~80% charging/discharging efficiency, looks good.
electrolysis efficiency lets say 15% max. Fuel cell efficiency ~50% efficiency rule of thumb. Charging the battery is probably between 80 and 90% efficiency depending on the battery used............
Probably putting in 380Wh of energy to get out a puny 24Wh of energy, plus extra weight, plus puny power... great stuff!
