The compression is a good thing, it drives the power to the turbine in the first place and also acts like a spring so it'll smooth out the energy impulse from the waves.
One of the big problems with other wave energy systems is the stress from waves is pretty peaky so the generators have to spin up and down a lot and then also deal with storms. In this the air acts like a cushion to the peaks of energy from waves and the whole power generation side can be bypassed in a storm even by just opening another air path.

- photojosh 6y agoI'm interested in micro-scale power generation from intermittent sources, so the other day I came across a paper [0] which discusses capturing the energy in gusts more efficiently: drive the turbine as if it were a motor when you detect a gust to accelerate the blades past stall. Very clever! Another comment below [1] also prompted my reply, if they do use the Wells Turbine, this is even more relevant.
