Electric Boat Costs 40–50€ to Cross Baltic Sea, vs 750€ Refueling Gas Boat

While the much lower fuel cost has to be a bit of a shocker (we all know EVs are more efficient and cheaper to operate, but not 95% cheaper), the bigger surprise has to be how much more convenient the electric boat was in a certain key way. “We actually had range anxiety, but not for the Candela. The irony is that the photographer’s gasoline-powered chase boat had to refuel six times during the trip, while we only charged three times,” said Gustav Hasselskog.

I've dealt with storing energy from solar for a long time now, and from the deepest part of my heart: fuck lead acid batteries. The only thing they have going for them is being able to charge below freezing. But they're shit in every other way, especially weight.
They have one other advantage: unit price. But Lithium is rapidly catching up, and is already better if you calculate price per lifetime charge cycle.
Recyclability, too
