Spiral Spring

[FONT=verdana, arial, helvetica]I am planning to build a bicycle with mechanical regenerative braking. I am thinking of setting a spiral spring to wind during braking and use its tension to assist in climbing hills

Would such a spring give me enough power for this? is it feisible???Are there any other alternatives for this?

    Fantastic Idea! 😀

    Just one doubt though, how would one control the breaking action?

    Haven't really thought of that yet, do you have any thought on that??
    The idea really is still in its infancy.

    ambush_xx you are going the right path right now. think about the ways for now, and design a few, mindstorm, dont think if it possible or not, or if its efficient. Just design. Slowly cancel out the weaker ones and start analyzing each one.

    Actually, using just breaking to wind up a spring to actually climb a slope is like a windmill connected to a spring which winds up when the windmill is running and then when there is no wind the spring pops in action to turn the windmill to generate electrcity, this goes against energy conservation (0'th law of thermodynamics). I still think I am wrong so someone d the math please. This topic is interesting though! 😀

    That would be one big spring

    You would need to know the force required to move the bike and sustain momentum on a flat surface and then over different inclinations.
    After calculating this you would then need to determine the size of the spring being used to perform the work.
    How would you apply it? I like the idea of using a centrifugal clutch.I toyed with this when I was 12, in between trying to make a rail gun that would fire darts into concrete and a mini steam engine.
    It will work you just have to be creative,try using a geared bike with a derailer system to take the effort out of it.BTW dont sit inside and design it get out and build your structure and adapt what you have,on a lighter note if you are not having fun with it stop for a while get some mates over and brain storm,dont take it too serious,thats when ideas start to spark

    Till now I have always been lazy to start new prozx., thinking it will take a lot of time, but your words have left me with a lot to think 😀 Thank you.
