Windpowerless - again

Has anyone ever seen the wind turbine at the CNE actually working, in living memory? Driving by tonight, as probably every night for the last 2 months, the thing was again not turning, not lighting up the 200 homes it was touted to power. The flag on the Medieval Times building was blowing fairly straight out, so wind speed was about 10 - 15 knots. If you can't make power at that speed, then when can you? If that marvel of technology is supposed to be a portend of how wind power will change our lives, then freezing / sweltering and eating cold food in the dark looks like the best we can hope for. But wait, the coal fired plants are still burning, the nukes are still nuking, so those 200 homes can still cook, still heat and air-condition, still read the paper and most importantly, surf the web.
