Not a discovery
Via RCS, a supposedly new finding about half-pipes used as wings.
Their figure:

Note that the half-pipe pushes downward at lower velocities, and upward at higher speeds.
Turn this upside-down and you get a half-pipe open upward, which gives extra lift at lower velocities. This upside-down principle was explored for a long time, with good practical results but little commercial success, by
Custer Channel Wing. CCW was mainly based in Enid and I had some indirect connections with it. I was never convinced that the company was trying to succeed; it looked and acted more like a tax dodge, a manufacturer of writeoffs.
