Can a vehicle be built which can go directly downwind, faster than the wind (DDWFTTW), powered only by the wind, steady state? Thin Air Designs, in collaboration with the San Jose State University Aero department, along with generous corporate sponsors intend to definitively answer this question. Follow our quest.
Here I've started making the rear axle/transmission enclosure frame.
This frame is 6ft wide and will stay this width for dyno testing etc. When we take the cart outside, it is designed to accept a plywood box beam built around it that will double it's width for stability.
