Oh yes, uh huh, for sure.I'm not an electrical engineer but I don't think that math is right - maybe an EE can weigh in. I suspect that the limiting factor is some combination of battery charger capacity and battery chemistry (how fast the battery will accept a charge). And I think for a lot of owners a small ICE running on propane would be preferable to a diesel or gasoline propulsion engine.
I so want to lug 8kg cylinders of LPG out to my boat. For fun I'll leave it to someone else to work out how long it'd take to use the contents and how many you'd need to carry as deck cargo.
Or go alongside a fuel dock with bulk supplies (which likely doesn't actually exist anywhere) to load up the BIG INTERNAL TANKS with LPG. Because they're *such* a convenient shape to fit into a boat hull.
Not to mention the sniffers and blower system that would be totally necessary... and let's not forget the hydro testing every so often.
Great idea, wonder why it hasn't been done already...
