Trap wind for turbines
I was reading how in certain places if two tall buildings are built close together they trap wind and send it rushing through the passage between them.
My idea is not to build turbines between skyscrapers as is often suggested but to build structures outside cities whose sole purpose is to trap wind and send it rushing through a narrow passage in which there are numerous turbines. The turbines can be built into the structure so only the actual turbine bit sticks out.
Given how much the turbines cost these structures could be built relatively cheaply out of concrete or maybe even plastic or wood on a metal frame.(i'm thinking flat plastic panels)
Unless i am wrong this should increase the output of each turbine dramatically.
