Thursday, May 6. 19»2 Wind, An Important Source For Electrical Power' By Christopher D. Turner Appalachian State University lies at the base of Howard’s Knob in Boone. North Carolina. On top of Howard’s Knob a 2 - million watt turbine built for the Department of Energy and NASA acknowledges the wind as an energy resource in the Blue Ridge Moun tains. Dr. J.L. Mackey wanted to prove that small scale wind machines could also harvest the wind as a source of electrical power. He wrote a proposal to the Department of Energy’s Appropriate Technology - Small Grants Program to demonstrate two small scale wind systems. One would be a 1500 watt wind generator designed to in terface with the utility, and the other would be an 1800 watt wind generator designed to store energy in batteries. In his proposal, Mackey stated that he would hold several workshops open to students and members of the community. The workshops would be taught at the Episcopal Mission Farm in Valle Crucis on land the Mission was allowing the Earth Studies Program to develop as an appropriate technology showcase. Although the Department of Energy did not provide the funding Mackey had FREE SOLAR SEMINAR 8:00 P.M. Friday, May 21st.

The Department of Energy also specified that it wanted both wind machines to interface with the utility. With these restrictions in mind, Mackey purchased twolsoo watt Enertech wind generators in the Spring of 1980. To help him teach the wind workshops, Mackey hired Charlie Hall from West Topsham, Vermont. Since 1971 Hall had been going out West to collect old wind generators and towers, and then bringing them back to Vermont for rebuilding and resale. Mackey and Hall had met at Goddard College when Hall was teaching a wind workshop there. The workshops began after the Spring semester of 1980. Mackey taught the theoretical portions and Hall the “hands on” techniques. The first workshop was held on a weekend which suited people who were not students better than the longer three week session which followed it. Both workshops stressed the fundamentals: Assessing your energy needs; measuring the wind as an energy resource; how power in the wind is converted to electrical energy; how electrical energy can be stored in batteries; how to figure how much storage you need, how a wind electric system can tie in with a utility; how to erect a tower from the ground up; how to install and service a wind system; tower safety, and the use of hand signals for communicating from ground to tower. As a member of the three week workshop, I can report that Mackey and Hall gave an intense workshop. We would often go from 7:30 in the morning until 7:30 in the evening. Over a three week period beginning June 9, 1980, Ron Duncan, Roland Grigley, Cindy Kiger, Kevin Parker, Jeff Whittington and myself became a skilled team and erected the 65 foot tower and safely installed the 375 pound generator on top of it. The wind system was dedicated on June 25, 1980, a month and a half after the initial grant was announced. Next to repelling out of a helicopter, working on top of a tower using a safety belt is about the most exciting thing I‘ve ever done. The thrill we experienced in installing the wind system and actually seeing it convert wind into electricity is something we shall always cherish. The Enertech 1500 is a horizontal - axis, down wind machine just like the two THE CHOWAN HERALD magawatt machine on Howard’s Knob. Unlike the big, two bladed wind generator, Enertech used three blades with a total diameter of 13 feet. The big wind machine has a blade diameter of 200 feet. Since the power you can get from the wind is directly related to the square of the Made diameter and the cube of the wind speed, you can see why the big wind generator is so much more powerful. Both the Big wind generator and the Enertech interface with the utility lines. Unlike the large generator which needs transformers and complex synchronizing gear, the Enertech simply plugs into a 20 amp wail outlet. The Enertech uses as induction motor • generator which receives its excitation from the utility line. For this reason, it will not operate when the utility power goes off. A wind measuring device called an anemometer is wired to the control panel. When the wind measures 10 miles per hour the anemometer signals the motor to start the machine up. Once the generator spins over 1800 revolutions per minute it begins to generate power. The generator reaches its rated power at a wind speed of 21 miles per hour. Winds over 40 will cause the machine to automatically shut down to avoid severe stresses. The Enertech System uses the utility as a storage system. When the wind machine produces more power than is being used by the owner, the excess feeds into the utility line. If the wind machine does not produce all the needed power the power company supplies it. The usual procedure for metering involves two meters; one for measuring power used and one for power produced. The utility pays you for your power at wholesale rate far then power at retail rate which is higher. I i . Hugh Brownlee, David Wood, Katie Spitzer, and Russell Taylor took the 1981 Summer Wind Workshop under Dr. J.L. Mackey. Integrated Energy Systems of Boone constructed and installed the tower and the students placed the Ener tech upon it using ropes and a gin pole. The gin pole is a sturdy steel pole about eight feet long which is clamped to the tower. The rope runs from a truck through a pulley at the bottom of the tower and up through another pulley at the top of the gin pole and back down to the generator. To get the generator to the top, the person on the tower signals the truck driver to back up until the generator is at the desired level. This is the method students used to mount the first machine in Valle Crucis and the second machine at Doughton Park on the Blue Ridge Parkway.

With that, the legislators and the people they represent probably will rejoice. But there may be trifle little for anyone to be rejoicing. One last final look at the redistricting argument might be enlightening. And probably no one hopes it will be the last look more than those who have been writing about redistricting. As things now stand, and of course they may crumble, the North Carolina primary date will be June 29. There will be only one primary (except for runoffs where applicable). The change from last week’s June 10 date is a result of the Justice Department agreeing to final redistricting lines, but only if North Carolina would allow extension of filing dates and a little extra time for campaigning. The extension of filing dates and extra time for campaigning are excellent objectives. The short time of the June 10 date was selfishly motivated by legislative incumbents who didn’t want opposition. But the rub comes because of where the directive came from - Justice had said they would approve N.C. redistricting with certain changes in a couple of districts - they had not even ventured into the area of primary dates (at least not publicly). The directive for ex tension, one might suspect, would have been more appreciated had it come from fair-minded legislators. It didn’t. In effect, the U.S. Justice Department again reneged on its word by threatening to veto the plans unless they got something else in ad dition to further district line changes (extension). Unfortunately, the legislators wanted the June primary date so badly, that they couldn’t tell the Justice Department to go jump and to take the matter to court - some of them were just too fed up with the whole mess. The words of Rep. Bill Watkins, D-Oxford, may have been those of a prophet G R O F 1 \ BUILDING CONTRACTOR <jj CUSTOM BUILT HOMES i V RESIDENTIAL - COMMERCIAL A V ADDITIONS - REMODELING - SIDING A A “QUALITY t GOOD WORKMANSHIP” J l FREE ESTIMATES , | l P.O.

Watkins had warned the General Assembly early-on to quit trying to satisfy the bureaucrats and take it to court. Watkins had cited UNC’s success against Washington intrusion as inspiration. Some say it’s too bad the legislators weren’t inspired. PERRY....At least North Carolinian Gaylord Perry is inspiring and inspired. The winning est active baseball pitcher won number 299 last week and might get number 300 this week. Only 14 major league pitchers have won 300 games in a career before. He is almost a certainty for the Baseball Hall of Fame, upon retirement. But why should he retire? The Seattle Mariners’ manager says the 43-year old fast-ball pitcher was the best on his staff during spring training, and Perry looks awful good right now.
