Woah - I've never heard of this type of power meter before. It also seems to solve exactly what the OP is looking for (which any type of power meter would also solve).

It kind of makes sense - measure the wind instead of the power - but there are so many other factors that come into play (gradient, weight, rolling resistance, etc) that I'm confused about how this works without making a bunch of estimations/assumptions. Riding at 15mph with a 15mph tailwind is easy, but it isn't 0 watts.
