Rob, but windmills may not be suitable for all cities or places. I my place we had implemented wind farms at certain areas, where wind is available atleast for 200 days/year. Other areas EB (Electricity Board) has instated solar panels for power generation. In certain places, they had implemented hybrid model, consisting of both windmill and solar.
"You don't normally find a wind turbine in the middle of a large metropolitan area, .......... has developed a wind turbine that can be positioned between, or atop, skyscrapers and large buildings to harvest wind areas in urban areas."
Elizabeth, but in my country we can see small wind mills over most of the buildings as a part of hybrid power generator. They used to install small turbine type windmill (hybrid mode) along with solar panels to generate power.
Nice story, Elizabeth. Interesting that wind could deliver half the world's energy needs by 2030. I'm sure that would require advances in technology. This window-based energy collector may be a contribution to that.
