Apple Hydrogen Fuel Cell Battery Plans Revealed

35. You are completely and consistently wrong on science.

"The energy efficiency of water electrolysis varies widely with the numbers cited below on the optimistic side. Some report 50–80%.[13][14][15] These values refer only to the efficiency of converting electrical energy into hydrogen's chemical energy. The energy lost in generating the electricity is not included. For instance, when considering a power plant that converts the heat of nuclear reactions into hydrogen via electrolysis, the total efficiency may be closer to 30–45%,[16] although the inefficiencies of powerplants in turning heat into electrical energy is not usually included in efficiency, so the former measure of 50–80% efficient is probably a more realistic efficiency."

That's just converting electricity to hydrogen; converting it back is going to be even lossier. So basically you're throwing out at least half of the energy you originally generated, compared to a battery which is upwards of 90% efficient in storing power. Hydrogen fuel cells have the potential to replace conventional generators for many applications, but when it comes to electronics and vehicles they're pure hype.

Really, jpak, you need to stop posting about stuff you don't understand.
