“It should be borne in mind that electrical energy obtained by harnessing a waterfall is probably fifty times more effective than fuel energy. Since this is the most perfect way of rendering the sun’s energy available, the direction of the future material development of man is clearly indicated. He will live on “white coal.” Like a babe to the mother’s breast will he cling to his waterfall. “Give us our daily waterfall,“ will be the prayer of the coming generations. Deus futurus est deus aquae deiectus!”

“The transmission of power has interested me not only as a technical problem, but far more in its bearing upon the welfare of mankind. In this sense I have expressed myself in a lecture, delivered some time ago.

“Since electrical transmission of energy is a process much more economical than any other we know of, it necessarily must play an important part in the future, not matter how the primary energy is derived from the sun. Of all the ways the utilization of a waterfall seems to be the simplest and least wasteful. Even if we could, by combining carbon in a battery, convert the work of the chemical combination into electrical energy with very high economy, such mode of obtaining power would, in my opinion, be no more than a mere makeshift, bound to be replaced sooner or later by a more perfect method, which implies no consumption of any material whatever.”

Sometimes the best way to appreciate a flow is standing still. In and the syrup flowing down a stack of pancakes have a lot in common. To me, this is one of the most beautiful parts of fluid dynamics: physics of flows on different length-scales and time-scales – even in different fluids – are still very much the same.
