... are seen in both artificial and biological entities. A more extreme example of this would be to say that any biological entity which makes use of friction is a tread, which is every single thing in existence. We designed a tread off the principle of equal and opposite force, which gives rise to ...

... that wind-farms use that sort of strategy, in that they use a small energy input (gas or recycled electricity) to overcome the coefficient of friction so their blades can spin at optimum efficiency. But in that case, the energy input is wind. Anyway, I think the original topic is of particular ...
