Sorry about the appallingly writen article, but the idea is interesting. I will be very surprised, if something similar hasn't already been tried.

Interesting it is. They would work fine with a wind generator, but I wonder how they would go in an automotive alternator and 7 or 8 thousand RPM.

I also wonder what, apart from endless springs would be used as flexible bits.
