When is a hybrid coming? FES plus a 10hp generator would be the ideal combination.

Solar cells.

It shouldn't be long before it's economic to embed solar cells under a thin smooth transparent layer (would gelcoat do?) of the entire upper surface of the wing.

At current efficiencies, a single seater with 10 sq m of wing will get about 2 hp, not 10, but that will still help as it'll be working almost all the time.
