AI Thread Summary
A laser device designed for wind measurement is being used on windmills to assess wind speeds several hundred meters ahead, allowing for real-time adjustments to the blade angles for optimal efficiency. This technology not only enhances wind turbine performance but also has potential applications in aviation for detecting windshear in front of airplanes. Additionally, similar laser technology is utilized in astronomy to correct atmospheric distortion for telescopes. Information on suppliers or manufacturers of these laser devices is sought for further exploration.

Hey there

Some months ago I read about a little gadget that was being mounted on windmills, a laserdevice, that could meassure windspeeds a couple of hundreds of meter in front of the mill, and adjust the angle of the blades accordingly. Do any of you people know anything about such a device ( the laserthingy ), please supply links to suppliers and/or producers... Thank you in advance.

Best regards

Thomas Hansen

It would be great for detecting windshear ahead of airplanes. A similar laser is used for correcting "seeing" (twinkling stars) through air for feedback to terrestrial flexible telescopes.

Thread 'ChatGPT Examples, Good and Bad'

I've been experimenting with ChatGPT. Some results are good, some very very bad. I think examples can help expose the properties of this AI. Maybe you can post some of your favorite examples and tell us what they reveal about the properties of this AI. (I had problems with copy/paste of text and formatting, so I'm posting my examples as screen shots. That is a promising start. :smile: But then I provided values V=1, R1=1, R2=2, R3=3 and asked for the value of I. At first, it said...

Thread 'MS 365 Profile Badge colour'

Sorry if 'Profile Badge' is not the correct term. I have an MS 365 subscription and I've noticed on my Word documents the small circle with my initials in it is sometimes different in colour document to document (it's the circle at the top right of the doc, that, when you hover over it it tells you you're signed in; if you click on it you get a bit more info). Last night I had four docs with a red circle, one with blue. When I closed the blue and opened it again it was red. Today I have 3...
