That would be a truly remarkable number for a fairing with open sides! I hope you're right ... it would be great if some university engineering department took an interest in this .

It's the best I've seen and frankly satisfies all my motorcycle requirements . I'm going to sell my current bike and buy a BMW 650 Cross Country , a very light fuel injected machine that would perfectly fit with a Vetter (style) fairing. I'd buy one from Craig Vetter if I lived a few thousand kilometers closer .

With a fairing like the one above the BMW should be good for 120 US mpg or 2 litres / 100 km at 60 mph. I'd be entirely happy with that and also with the enclosed storage area and lack of wind noise ... that last one might just be the most pleasant !
