The mighty Biketrans or transglide 2000

The Transglide system goes all the way back to 1997 (possibly earlier I'm not sure). I love the drawings of the system wonderful, this is elevated cycle ways as they should be. I think Milnor has got all the right ideas, elevated (naturally), stations, bikes don't have to have as structurally over designed as pedestrian or car ways,  but the clever stuff to notice is

• Separate up/down sections so you can push the air to encourage faster flow by lowering air resistance(1).  
• this means you can travel much further much faster
• Optionally charge a toll per trip ( you have on/off stations so you can do this).
•  This could make the system financially self supporting. 

I remember someone once critiqued that pumping air down was a energetically too expensive and I wrote back defending the Transglide pointing out that this was putting as much energy in as running a bus ( i.e. its still better than a car). This made me realise that in strong winds cyclists are putting in as much energy as a bus - which seems a bit much to ask, why not protect them from strong winds?

Still I'm getting off the point, Check out the transglide system it's cool.
