Show Windmill Farms' Farms In In tile Future If experiments conducted by bythe bythe bythe the National Aeronautics and Space Administration and the National Science Foundation prove successful electricity for your home may someday come from windmills NASA and NSF are arc working working working work work- ing on on a year five-year program to study wind energy systems This program is one aspect of Project I Independence designed to reduce US U.S. dependence on foreign energy sources As part of the wind energy study Lockheed Corp has been awarded a contract contract contract con con- tract to design develop and test a huge set of windmill blades The blades will be used to power an experimental wind turbine generator at al a NASA station in Ohio Two 60 blades long foot forming a rotor will be mounted on a foot foot tower Transmission equipment will drive the generator at 1800 rpm generating kilowatts of electricity enough electricity enough to power 1000 watt bulbs A supplied NASA-supplied mechanism adjusts adjusts adjusts ad ad- justs the blades to the speed of the wind keeping them moving at a constant 40 rpm If the system proves practical and economically competitive we may see a day when five to 10 per cent of our power will come from windmill farms predicts predicts pre pre- diets Tom Higgins Lockheed's manager from NASA programs pro pro- grams |
