The most important news you'll hear all week

This is the most important thing you'll hear all week. I don't care if Russia captures Kiev and hangs Zelenskiy by his toes, this is more important.

Archimedes wind turbine

This brochure for the Archimedes wind turbine looks pretty cool.  Until you read it, that is.

Unfortunately, at normal ground-level wind speeds (5-10mph), it produces negligible power (well under 10% rated). It starts being effective (near 50% rated power) with 20mph winds, but is only rated for 28mph (100/550 watts), and then cuts out at 31mph (140/780 watts).

That's a very narrow window of effectiveness to produce, at best, a few score (small) / hundred (large) watts of power.  It doesn't help that the brochure is self-contradictory in places.  Do they need a better editor, or better (more consistent) facts?

On the other hand, how many could you fit on the average rooftop?  The big one is five feet across, 6¼ feet long, and weighs 620 pounds.  The little one is 2.5' x 3.6' and weighs a 'mere' 135 pounds, but only produces about one-fifth the power.
