The quiet boat on Mirror Lake

Stellan runs a small electric tour boat on a clear mountain lake. There is no engine noise, so guests can hear loons calling across the water. Before every trip, he checks the battery bars on the little screen by the wheel. Then he welcomes eight guests aboard and pushes off from the dock.

Halfway across, a bald eagle swoops down and snatches a fish right beside the boat. Everyone cheers. Meanwhile, Stellan glances at the screen and smiles, because the bars still show plenty of charge. So he takes the long way home, past the waterfall. In short, knowing your charge at a glance makes any trip feel easy.
