Colin Sproul, again..The nonsense continues: Colin Sproul just did another CBC interview, this time on The Current. Sproul covered the same stuff as before with a few new howlers tossed in:
- Sprowler # 1: Sproul thinks that the Doppler effect will prevent the fish from hearing the turbine. Well, here he's just following in the skid-track of others. The fishermen have this crazy notion that the Doppler effect will block sound from travelling upstream!
I kid you not. I have seen it in writing...
Just for the record, the Doppler effect modifies the frequency of a sound wave. The speed of sound in seawater is about 1480 m/s which is more than 6 times faster than the speed of sound in air. By comparison, the current speed is a measly 6 m/s tops (about 2 m/s on average). The change in frequency depends upon the ratio 6/1480. The Doppler effect would be very,very tiny.
The current would have to be faster than the speed of sound in order to prevent sound from going upstream. Perhaps when the planet gets torn apart by an exploding star...
This Doppler effect howler went right over the head of the interviewer, one Anna Marie Tremonti.
- Sprowler # 2: Sproul makes the common mistake of thinking that turbidity will make the turbines difficult for the fish to see. (The sensory system of a fish goes well beyond vision, btw.) The water isn't turbid where the turbines are going to be installed in Minas Passage. Sure, the water is turbid in Minas Basin --- but no one is talking about putting tubines there. I suspect that Mr Sproul is either geographically-challenged or hasn't figured out the difference between turbulence and turbidity.
- Sprowler # 3: Sproul demanded that that a new environmental survey be done to determine baseline conditions "with oversight by affected historical stakeholders".
Hah, the fishermen think that they should be running the science. Well, that's what happened with the Newfoundland cod fishery. The fishermen convinced the government to ignore the science and look how that worked out!
As arrogant pinheads go, Colin Sproul takes first prize.
