Personal Rapid Transit (PRT) is an automated, elevated, small-vehicle public transit system that could "un-gridlock" the world's cities.
This sort of thing has been done often, but only on a small scale--rides at theme parks, for example. *Lots* of folks have tried for many years to come up with a design that would work on a *city-size* scale, but it's a lot harder than it first seems!
For example: a single loop of this system would use about 1,600 vehicles, and eventually a large city would have roughly six to ten loops. So we're talking *lots* of vehicles here!
After over a decade, we think we've solved all the problems, IF...we can get our ten-foot-long, two-seat vehicle bodies to come in at about 250 pounds.
The big challenges here are: *durability!!*, low parts count--probably around a dozen molded parts, bonded together; and of course high rigidity.
We're looking for someone who can *play with this* along with us for a share of the equity, for a year or so while we try to raise funds for the first prototype, half-mile-long loop.
If you're interested, check our website at //ourworld.cs.com/PRTDesign/ , or email me.
Thanks to all--and Carl!--for the forum.
