I’m attending the CanWEA / AWEA Wind Integration & Forecasting seminar in Calgary. While the hotel is very nice, I should’ve pegged there might be trouble when the room next door to mine is marked Crew Lounge. And yep, between 0100 and 0300, the crew was there. And they lounged loudly.
RE Imaginations – Renewable Energy Art
I was about to rush off and tell Emma Jane about RE Imaginations – Renewable Energy Art, when I discovered she exhibits on it already.
(They had a nifty display at AWEA, and I just bought an Aleksandar Rodic print.)
it’s over ….
AWEA 2006, that is. Best swag was probably the places that had USB keys; yeah, they’re only 64MB, but these are big enough for tiny Linuxes or restore tools.
Freebies aside, it was a great show, and I guess a few hundred thousand business cards changed hands.
drinking with the wind
I didn’t go to the AWEA banquet last night, but did sneak into the GE Wind event (to which I was semi-invited) at the Andy Warhol Museum, and then on to the Clipper event (to which I definitely wasn’t) at the insanely ornate Heinz Hall. I guess you could say that place amounted to a hill of beans.
Caught up with Norman & David Surplus of B9, whom I last saw more than a decade ago. As there was free drink, I am slightly fragile this morning.
And so to pack …

AWEA06: by the river (or in it, nearly)
We’re not getting the best weather for the conference, but I hear that the coincidentally-running Three Rivers Arts Festival has had rain 18 out of the 20 years it has run, so noone’s surprised.
Conference hasn’t quite started yet, but the preliminary swag is quite promising; yoyos and balsa aircraft.
I spent the day in workshop run by KidWind, who have a school science kit for teaching the basics of wind turbine effectiveness. We got to build wind turbines, and test them. Here’s mine, big wean that I am:
I guess I got some losses near the hub there, but at least it worked. I was the only developer type there (there was a DoE person, and lots and lots of Pennsylvania teachers). I came away impressed, and hope I can work with Michael Arquin of KidWind to bring the project to Ontario.
(This post has the worst GPS location ever; could only get a fix to within 100m, so that’s why the map location appears to be in the river.)
Pittsburgh: I’m only hea for AWEA
In town for the AWEA 2006 Conference. Pittsburgh looks like it has some interesting topography, and has some huge buildings downtown. Trying to get a GPS signal for the map (amid a bemused high-school prom crowd) was hard.
WindSave: All Betz Are Off!
Update, May 2005: While it’s true that WindSave appear to have made their device obey the laws of physics (at least according to their published spec), I’m keeping this posting intact.
If the data on their website are to be believed, WindSave cannot generate the figures they claim. There’s much geeky theory involved, but basically, they’re claiming efficiencies that cannot be attained.
In short, they are claiming coefficients of performance of 0.724 and 0.887 for their turbines. Unfortunately, the theoretical maximum efficiency for a wind turbine â€” the Betz limit â€” is 0.593. So something, somewhere, is screwy. I’m pretty sure it’s not my sums, as they’ve been verified by an external source.
I worry that the UK energy minister, Brian Wilson, has been taken in by this. Five minutes with a calculator and a wind energy primer shows that these things are too good to be true.
