Typically a rubber tube filled with water will bulge locally when squeezed; and this bulge will propagate along the tube at a speed  c given by

Here E is the tensile modulus of the rubber, d the diameter of the tube, h its wall thickness and rho is the density of water. You can control the speed by choosing the dimensions of the tube and the properties of the rubber.

Isn’t that simple?  Just kidding but the theory sounds a little less complex.  Put a rubber tube in the ocean with a generator at the end and the waves produce power.

Alex Steffen from worldchanging.com wrote this incredible post in January about what is next. Very worth your time. I missed it when it first came out and just found it today on their blog. Its incredible.
