Petroleum Wind

As sailors we are well acquainted with the centuries old idea of using the wind to move things (except when they capsize).  Harvesting energy from wind today is increasingly fashionable and visible with wind farms everywhere.

But we usually think of wind as the product of the weather - heating, cooling, isobars, coriolis effect, etc. 

But here is a proposed bridge in Lisbon which takes a more imaginative look at a wind to harness - ironically produced by the burning of fossil fuels in internal combustion engines.

The proposed bicycle bridge across a busy highway has 2,188 lightweight rotating panels which produce electricty. As traffic goes by under the bridge the turbulence produced turns the panels.
