We put water in the wave tanks today. After a few small adjustments, they seem to be operating very nicely. The process of filling and testing them drew a decent-sized crowd of curious youngsters.

At Mark’s urging, I tried to create an impressive tsunami in the smaller tank. A single, mighty heave barely produced a ripple.  This is good, as it means visitors with this goal will need to spend a few seconds fine-tuning their timing and rhythm to meet it. It is satisfying when you get a nice, even stream of deep waves marching down the trough.

Alan is in the process of testing out his wave energy demonstration device, which is essentially one of those electromagnetic flashlights you shake up to charge, with a float attached. It’s simple but effective, and it seems like common sense once you see it in action.
