14 GalfsbufQ Registe^Mail, JSajesbwgJH. : fridoy, June J&,A9?& It's a wind tunnel model of an advanced technology Remotely Piloted Vehicle being designed for NASA's Ames Research Center, Mountain View, Calif. Such an all-wing RPV h'as wide potential for civil and military New Design uses. The final craft will have a 90 horsepower engine, 22-foot wingspan, and will cruise around 130 knots. Weight will be about 500 pounds. NEA Earth's Magnetic Field Is Eyed as Source of Power By CARL A. VINES KNOXVILLE, Tenn. (UPI) Back in the early 19th century, Michael Faraday decided he could put electrodes into a river current and make use of the earth's magnetic field to generate electricity. Energy World The idea didn't offer much prospect for power generation then, and the World, including Faraday, went in other directions. But the notion is alive and well in Tullahoma, Tenn. It isn't river current and earth magnetism that's being used. But researchers at the University of Tennessee Space Institute at Tullahoma are using the same principle in power generation studies. And they're so convinced they have proposed to Congress that $300 million be appropriated for a full-scale power plant by the 1980s. One of Two Dr. John Dicks is head of the program investigating mag- netohydrodynamic power generation at the Space Institute. His is one of two major projects in this field, and the only one studying coal-fired generation. There's another at Everett, Mass., where the clean fuels- natural and petroleum gas—are being looked into. And eventually, the process may be extended to nuclear powered generation. The idea is that gas from the coal. burning. process, laced with a potassium compound to make the gas conduct electricity, is run . through a magnetic field to produce electricity. "The coal is burned with preheated air, perhaps with some oxygen," Dicks says. "The gas is fed through a nozzle to get it moving fast—about 3,000 feet per second. Then it runs through the magnetic field, and the electrical current is picked off with electrodes surrounding the gas." Temperature Is Key The key to the whole thing is the high temperatures attained from the burning coal, about 3,300 degrees kelvin or roughly 6,000 degrees fahrenheit. That's about three times as hot as a conventional coal-fired steam plant gets in its operation and is much higher than the temperatures of conventional nuclear power plants. Such high temperatures required development of special materials for the equipment involved, of course. Part of the solution was to use coal ash to coat the electrodes, Dicks said. The coal ash acts on the electrodes in much the same way as the ash in the bottom of an old coal heater protects the bottom of the stove from being burned The,re are a number of attractive aspects to the process. First, in' introduction of potassium to the heated gases, the sulphur content of the coal is completely precipitated out as potassium sulfide. And through simple chemical procedures both the sulfur and the potassium can be recovered for other uses. " Heat waste Is cut 50 per cent, compared to other generating processes. The power plant lasts longer because it practically has no moving parts. And the process is far more efficient in power production than other procedures. For instance, the average coal-fired plant is about 40 per cent efficient while convention' al nuclear plants have an efficiency of about 32 per cent. But with the MHD procedure, efficiency climbs to around 65 per cent. Alexis Appropriations. Trustees Include Provision For Waste Works Program ALEXIS—A $523,250 appropriation ordinance for the 1973-74 fiscal year—including $369,255 to upgrade Alexis' sewage treatment plant if federal and state funds for the work are also received—has been approved by the village Board of Trustees. The waste works project would cost the village about $80,000, with the federal and state governments providing the balance. IN.OTHER BUSINESS at their meeting Monday night, trustees agreed to seek federal assistance to develop low- rent housing for the elderly. Board members will meet with state and county officials to discuss the proposal. Trustees noted that the project is probably some time away. The federal government in January imposed an 18-month moratorium on funds for such projects. Other action taken by the trustees included: —Accepting the $650 low bid of Harney-Morgan Co., Aledo for a 10-horsepower tractor and 42-inch mower, including trade-in. —Agreeing to require payment of water bills by 15 days after the first of each month. Trustees said the village would charge $10 to turn on water if it is shut off for nonpayment. —SETTING THE CHARGE for connecting to the water system at $150 which, trustees said, would cover the actual cost of the work to the city. Costs have risen 100 per cent in the past few years, board members said. —Approving two requests to annex adjoining property, including two acres along North Henderson Road owned by Paul Davis and a half-acre on North Henderson Road owned by David Winkler Jr. Also at Monday night's meeting, trustees ordered village officials to contact persons responsible for property where grass and weeds are higher than permissible and junk cars and trash are stored. Offenders will be asked to remedy the situation.
