Non carbon based Alternative renewable fuel sources..Ideas out side of the Box. #1. WIND POWER using a gigantic wind sock. A Wind Drome. Lets imagine a high tensil lightweight material 1000 feet across and 1000 feet high funneling down to an opening only 10 feet by 10 feet at the small end. ( supported by Helium dirigibles tethered with high strength cables, or towers with guidlines). The first 75 % of the structure would be the fabric the smaller 25% would be rigid with the outlet feeding a high speed turbine to a direct drive non geared Generator. louvers on the ridged structure would control the output of the wind velosity going into the turbine. It would make propeller driven windmills obsolete, because of the friction loss through gearing necessary to turn electrical generators at the speed required to produce power. These Wind Dromes could be located in mountain passes which naturally channel wind, or at locations of known constant wind and wind direction. They could be designed to rotate 45 degrees from center in either direction, left or right. I hear there is research going on right now on this same topic. Can anyone comment or direct me to the proper forum?
