H 1 By Barb Bierman Construction of a small wind-powered electric generating system north of Lincoln should be completed this week, according to the associate dean -of the UNL College of Engineering and Technology. Donald Edwards, wno has been active in promoting wind generators as an alternate energy source, said erection of a Pinson Cycloturbine on the John Carter property at 7300 N 7th St., could provide as much as 38 percent of the power needs of the Carter home. The generating system is part of the U.S. Department of Energy's (DOE) pro gram for Small Wind Energy Conversion Systems (SWECS), Edwards said, and is being put up through cooperation with the Lincoln Electric System (LES). SWECS is administered by Rockwell International and Nebraska is participating in the pilot program in which Rockwell hopes to place two conversion machines in each state. Edwards said sites were screened throughout Nebraska last summer and the two selected were the Carter property north of Lincoln and the Robert Scott home in Grand Island. Spiraling costs In these days of spiraling energy costs, wind as a possible' renewable energy source definitely must be explored, Edwards said. The cycloturbine being erected north of Be careful who you meet going to Walpurgisnacht By Lucy Bighia A word of warning to anyone planning to let loose and get into the spirit of things at tonight's Walpurgisnacht festivities: read on before making that possibly fatal decision. The Union Program Council may be bill ing Walpurgisnacht as Lincoln's own "All Night Winter Festival," but the real occasion has a much different history, Walpurgisnacht-German for "Walpur gis Night"-was historically a witches holi day observed the night before May 1. The holiday, also known as a witches' fire festival, marked an important Sabbath for witches and sorcerers. Rumor has it the witcheswould ride to the Brocken, the highest peak in the German Harz Mountains, on the backs of demons in the form of goats or asses or through the air on broom sticks. There they would hail their master, Lucifer, with cries of "ooroorake "-from which the word "eureka" is said to be de-rived-a shout which conjures up fire. Those covens (groups of witches) that found the Brocken too crowded for their taste would congregate in open places or at crossroads to perform their rites and re affirm their subservience to their master. The witches supposedly anointed them selves with oil made from the fat and marrow of murdered babies to attend their service, which was actually a parody of the Catholic Mass. Novices were accepted into the coven, and members swore fealty to the master while placing one hand on the head and holding the sole of the foot with the other. The initiate would then receive a new name while being pinched by an imp to make an indelible blue mark. Then came the real fun. The witches would feast on stolen food ' and dance wildly around with their backs to the center of a huge circle. The devil would pick one lucky young lady to be his partner for the evening,' while the rest of the witches paired off into couples, and the whole group then engaged in a frenzied orgy until dawn. The namesake of such merrymaking-an English nun-would probably be scandal ized 1 at the turn of events her holiday had taken. St. Walpurga, who died in 778, was best known for founding religious houses throughout Germany. Her name later be came linked with the Sabbath, much to many Christians' dismay. So the Christians decided to fight back, They picked up the habit of ringing con secrated bells to ruin the rhythm of the witches" merrymaking. Lincoln is a horizontal axis machine manu factured by Pinson Energy Corporation of Marston Mills, Mass. According to Ed wards, it is not typical of most wind energy converters as it resembles "an egg-beater". LES is working to connect the system with power lines, using the principle that if the home needs the power, it goes there, otherwise excess power goes into the line, Edwards said. ' "It is a complex situation trying to balance those loads," he said. A different machine will be installed by the Grand Island Utility Department on the Scott property. The Grand Island site will be used to i iL . c .. .: l analyse uie acceptance ui wmu niacmiica in nlmnst nrhan settings. Edwards saidl' "We're trying to see how close to resi dential areas we can put them in. Factors such as noise, radio and TV interference, and aesthetic value are all things we don't know for sure how to deal with," he said. Which is best? Placement of the wind machines is critical, but Edwards said they are not certain which is best. The Lincoln site is on a hilltop, whereas the Grand Island generator will be located on a flat area. "Who knows, perhaps updrafts along the bluffs by the Missouri could be our next site to experiment," he said. Edwards said data from the two sites will be collected and analyzed for the next two years. "Response to the project has been so favorable that there might be a possibility of getting two more SWECS for Nebraska by mid-1980," Edwards said. While work on storing wind energy is still in the experimental stage, Edwards said two other researchers at the university are working with projects utilizing .wind energy. Wayne Martin, professor of engineering mechanics, has been trying to reduce the -high costs of windmill motors by con structing them out of high-strength con crete. Since costs are 10 to 20 times too high for economical power production,-., alternative building materials may be the answer. Nitrogen compounds Richard Gilbert, professor of chemical engineering, has been experimenting with using wind to create nitrogen compounds for use in agricultural fertilizers. Edwards said these projects have potential, not only for wind, but for solar applications as well. . "Solar and wind systems provide a dif fused source of energy, while oil, gas and coal are more concentrated," he said. Though most projects are still in experi , mental .stages, .the. , application . of .older; principles to new technology could provide a solution to the energy crunch, Edwards said. "It would be a tremendous accomplish ment if someday 5 to 10 percent of our energy would come from the wind," he added.
