The trouble with water canons, according to the EXPERT they had on the BBC earlier, is that when they run out of water, they have to be refilled.
I'm really glad that they had an EXPERT on to explain that really complex concept for me.
I think it's similar to the early electric cars that could only go so far as the mains plug would allow.

Would that not be some sort of scalextric set?
If we hooked into the existing tram network in those cities that have them, we could feasibly connect the tracks up to the mains and have us all travel around in large plastic cars that impossible to control.
That'd be awesome! And we'd never need mechanics again, as it'd just be case of getting underneath and flattening/straightening the brushes out again.
And the headlights would randomly stop/start working for no apparent reason.
And random sections of track would lose power despite being connected perfectly and having every appearance of being totally fine.
