a: chlorophyll ~
b: windmill
What:
WTF you say? Yes. How can this association be? The point of similarity is that both things convert energy from one from to another. A windmill coverts wind energy into useful mechanical energy, usually to pump water from a well. A more modern application is converting wind energy into electrical energy for general consumption.
Chlorophyll does something similar. It coverts the energy of a photon, light energy into chemical energy that is used to create sugar during photosynthesis.
Both of these things act as intermediaries in their respective energy conversion systems.
Useful?
