I always envisioned a covered bike path, possibly elevated, using solar and wind generators for power for lighting, ventilation and such. At various points along the pathway blowers would feed in wind creating a non stop tailwind to help "push" folks. The isolated pod idea, while visually cool, leaves too many search and rescue in the case of failure issues on the table.
Kudos to them for actually building a prototype though, at least someone's trying something. There has to be follies and failures before someone hits the nail on the head.
Not everything can be properly envisioned in 3DCAD.
Now work in a gearing assist, and you have a human powered roller coaster baby!!!
