Just posting to say thank you to Bondo and everyone who's kept the "aerocap" concept alive here. I found this thread back when it started, looking for ways to improve my father's F-250 diesel pickup. I now own a 2006 Tacoma and am thinking of ways to improve it's lackluster 18 mpg (the F-250 gets that!
).
If I still had free time I would mock up some molds, but I just started medical school and I am barely managing to find time for the wife and dog anymore... hopefully I'll be able to buy an aerocap in 4 years after I graduate!
