The local wave generator I was talking about is an adaption of the Islay and kicks it's arse with some insane internal mach numbers for the air flow.

I missed that yesterday, sorry.. Did they explain how they kept the generator spinning in the same direction even though the air is moving in opposite directions?

I can't seem to figure that part out yet?

Edit: Is this the company you speak of?

Ohhh, they change the blade angles I think.... coool....

Most turbines are designed to function for gas or liquid flowing in one direction and at constant velocity with the blades designed to take advantage of the optimal ?angle of attack?. However, when the flow is not always from the same direction or a constant velocity, traditional turbines become ineffective.

Previous attempts to address this difficulty have mostly resulted in turbines with varying degrees of efficiency. The Energetech turbine, however, uses a different method, which with its slower rotational speed with higher torque improves efficiency and reliability and reduces the need for maintenance.

The turbine uses a sensor system with a pressure transducer which measures the pressure exerted on the ocean floor by each wave as it approaches the capture chamber, or as it enters the chamber. The transducer sends a voltage signal proportional to the pressure which identifies the height, duration and shape of each wave. The system will be calibrated to small-scale ?noise? from activating it.

The signal from the transducer is sent to a Programmable Logic Controller (PLC) which adjusts various parameters which will be selected based on particular conditions and energy content of each site.

I come from a land down under
Joel: I didn't really "watch" it when it was on just sort of listened as background noise ;)

Pretty sure it's the same company and they quoted insane air speeds through the system so you'd want it anchored a few miles offshore!

Or, they could make some "mufflers" to quiet them up. Keep them close to shore so they are easier/less dangerous to maintain if they do need any work...perhaps..;)

It's just a matter of bouncing the sound around a few times to defuse it to weaken it out, then focus it down ward..

LoL, I dunno how loud they are yet so I will have to wait and see I guess..

I know this has nothing to do with drag cars, but when I find another small 4 cylinder car to replace my '88 Honda Accord, I'm giving serious consideration to stripping it down, and building it as an electric vehicle. If I can manage 100-150 mile range, then it would do all the daily traveling I'd need!

Any body know how to make a scooter with a weed eater engine, cause I've got an extra weed eater and would like to make me a little goped.

Road trips would be a no, though.

I agree, 100mpc would be fine for me... Seems like most have a small gas motor now to use as a backup if needed.. They will fix that with hydrogen and solar I think..

This has turned into more of an alternative to gasoline/coal/foreign oil thread more than a drag thread.. lol

I would like to find a late 80's MR2 and convert it to electric. :)
