As long as one can steer clear of traffic (as the driver in this video does not demonstrate), this little homemade kart seems like a great way to get around. It’s got a battery for propelling itself, and pedals for extra speed, powerless propulsion, or charging the battery (I assume).
Modest, low-power vehicles like this are also prime for being solar-powered; imagine if everyone in the US had one of these for trips to the store instead of taking the Range Rover. You could probably burn a hole in the world with all the gas we’d save. In fact, that’s a good idea. [via Treehugger]
