This is a foil I generated in a couple hours based on a challenge.

It has a fairly high lift coefficient over a very large alpha range, if the Reynolds number is high enough. For low Reynolds numbers it still has a high max lift coefficient. Note it is not optimized for drag. Giving up about 10% max lift allows cutting the drag about in half. But the goal was lift, regardless of drag.

It is too interesting not to publish, so...

It might be useful as a starting point for wind turbine blades or possibly even rigid sails.
