As a rule ecomodders find that the combination of hypermiling techniques and a full aero package results in doubling the stock fuel mileage. What materials are readily available locally?
Your riding position determines your shoulder height and the top of the main shell. The optimum body shell would likely be a 3:1 airfoil shape with a Kamm tail (0.85 x length) and curved sides. See the classic sailplane designs and the HPV body shell design software at recumbents.com. Attach the shell to the frame and not the forks. This greatly reduces the effects of side winds.
