I'm just watching waterworld ont telly.
This guy is building his own barge, with no rudder, instead it has a two 14kw electric motors at each end, which I would assume needs a bugger of a lot of batteries, however all we can see is a bank of 16, which he says will give him 36 hours of travel, I suppose there could be another bank at the other end making 32 in all, but it still doesn't seem to be enough battery power to me.
