I'm sure I'm way behind on this, but yesterday I flew on a new 737-800 with "Split Scimitar" winglets. One airline claimed 3% fuel savings. That seems optimistic to me, but every little bit helps. Is anybody working on adaptations for gliders?

3% compared to no winglets or compared to previously used winglets?
Hmmmmmm

"Each traditional pair of winglets on the 737 cuts fuel consumption by 3.5% to 4% on flights of more than 1,000 nautical miles. The split scimitar upgrade--which costs $545,000, before discounts-will reduce fuel burn by up to 2% more, says United, which hopes to save up to $60 million a year because of the devices, once its fleet is outfitted."
