... All the wind power turbines are down.
Well, it's freezin' down in Texas.
All the wind power turbines are down, now...
Got a problem with the powerhouse baby,
down by the riverside...
Da da da dah, di-da da da,
Da da da dah, di-da da da...
It doesn't matter what blues song I start out with in my head, this one being Stevie Ray Vaughn's Texas Flood, it ends up turning into the 3rd line of Cream's Down to the Crossroads, a classic white version of the famous blues song, and continuing from there.
With a couple of exceptions and a streak of posts about our main squeeze
The eyes of the country are on Texas (but let's not ignore Louisiana either), as this Global Warming-caused deep freeze has paralyzed the place with cold and power outages. I guess not all the green sources work so well when it's all white out.* We wish the best for the poor Texans freezing their asses and hope there will be the right lessons learned from this hopefully short-term trouble. From the great blues player/singer Stevie Ray Vaughn, lost to us way back in the summer of 1990 in that helicopter crash, and his band Double Trouble here's Texas Flood. This live performance was at the El Mocambo Club in Toronto, Ontario.
* I haven't read that many details, but I was wondering whether the wind turbines froze up while in resting position due to lack of wind, or did they actually freeze up all like this even when in motion? I also wonder whether ice flies off the blades from inertial forces as it does from the outer regions of airplane propellers (the inner portions are heated up electrically, if at all). Let's see ac = ω2r. These things spin at something like 10 - 20 rpm (just calculated from tip speeds and blade length of some typical models). That's ~ 2 rad/s2 (150 ft) = 600 ft/s2. For a small aircraft prop, you've got about 2,500 rpm and a 2 ft radius to the outer edge of the portion that needs de/anti-icing. That's 262 rad/s2 (2ft) = 137,000 ft/s2**! There's no comparison. If the inner portions of aircraft propellers can ice up, then those wind turbine blades could ice up easily at their fastest speeds.
** This inertial acceleration seems so HUGE, but the math is simple. Please let me know if I screwed it up, ASAP.
