Personal Water Craft with this tech, would be hell on the Excedrin market. No more homeowners with headaches.
Seriously though, this tech is interesting, but it's gotta be better, and cheaper than gas, for it to kick in. Also, I've ran more than a tank through a Sea Doo in a day. I better be able to get a set of spare batteries for about $30.
Not trying to be negative. My next lawnmower is likely going to be electric. My trimmer and blower already are.
