Well actually I'm wondering if the following is possible. If you put enough dynamos on a bycicle wheel could they produce enough energy to keep the wheel spinning?A kind of a perpetuum mobile maybe?Why shoudn't it be possible when you can put many dynamos?But will the friction be so huge that...
So my question is actually really simple.I want to know approximately how much energy does a normal dynamo produce when a bicycle wheel is spinning (at let's say 10 km/h).Please answer me with a number not with a formula because I'm really bad at physics but i just want to test a theory of mine...
