Tube conveyor
Moves bicycles, skates, scooters, wheelchairs and prams. | |
A flexible tube is laid along the ground. It is designed to lay flat, with the top part of the tube laying on the bottom part of the tube.
Now water or air is pumped through the tube, causing the top and bottom to separate a little.
When a bicycle is ridden on the tube, it pinches the top to
the bottom and the pressure builds up so that the tube increases in height behind the wheel.
Thus the wheel rolls downhill and forwards.
A bit like a peristaltic pump in reverse?

I think your city council has nearly uncovered a diabolical plan of some sort, likely involving flooding something. But if it's too expensive to investigate, they should just forget about it. |

What does that have to do with tube conveyors? |
|

Good idea, [Ling]. Only issue I see is the material wearing out. |

so basically the bike acts as a constriction in the line which is pushed forward by the water pressure. the problem is that it would take a heavy weight to keep the constriction water tight. any real pressure would lift the wheel and water would leak through. |

I didn't mean it to be water tight. A slight constriction should do the job. As you say, "any real pressure would lift the wheel". That's what I want, and it has the advantage that many riders can use the conveyor together, since water can leak through to the next wheel position. |

that's a long way to go for a little bit of transport |
