Geothermal Energy OffersCapab'dityOf Powering Industry KLAMATH FALLS Ore. (AP) -- Klamath Basin, a rolling prairie in the shadow of 'he Cascade Mountains in southern Oregon, is the focus of a new American land rush. It has nothing to do with farming or precious minerals, but with hot water. Geologists believe this region sits atop one of the earth's richest stores of geothermal energy: , vast, subterranean reservoirs of high-pressure steam and hot water capable of spinning turbine generators, producing electricity, powering industry, casing the burden on dwindling fossil fuel supplies. "More heat energy lies within one mile of the surface in ·southeastern Oregon than in all of America's oil fields," sale! Dick Bowen, economic geologist with the Oregon Department o'i Geology and Mineral Industries. "Of course, we can't recover all of -that. But even i we could tap 1-lOOOth of it, it would be significant -- something on the order of the Norll: Slope of Alaska." Early this year, after prod' ding from scientists, industry leaders and politicians, the U.S Bureau of Land Management began accepting applications for leases to explore for geo thermal energy' on the vas tracts of-federal land in its do main. L LEASE APPLICATIONS The bureau was deluged. In the first four months of 1974 bureau regional offices in the Western stales received 3,50 geothermal lease applications covering 7,768,778 acres. Applications came from many ot the l a r g e oil com panics'-- Mobil, Gulf, Chevron Phillips, Sun -- and dozens o smaller ones. Geothermal energy is nolhin new in these parts. A hunderi years ago the Klamath Indian were using hot surface spring to cook their food and sooth arthritic limbs. In ».he early 1920s, crud wells were dug and siibsurfac hot water was lapped for horn heating. Today, geotliermal wells this town of 16,000 provid clean, and almost cost-free hea for some 500 homes, sehoo and businesses along what called the Hot Springs Belt -an area of several square mile that outlines a vast hotwate reservoir 300 to 400 feet down This is believed to be Ih most extensive use of gcothe mat home beating. anywhere. The economic savings of ge thermal energy, - even at tl fundamental level of direct h water heating, can be conside _. able: · . ECONOMIC SAVINGS stitute of Technology, a four- year, state-owned college on the outskirts of Klamath Falls, was spending $94,000 a year for heating oil. Today, on a new, larger campus healed by geothermal wells, the annual heating bill is about $8,000. For example, Oregon In- Public Schools Supt. Earl Ferguson heals his home with a hot-water well and says it costs him about 3 cents a day. Ferguson's geolhermal system takes no hot water out of the ground. A city ordinance bans it to prevent depiction of supplies. Instead, in what is called a down-bole eychanger, cold water is piped into the well, heated to near boiling within the pipe by the hot ground water, then pined back up and into the house. The exchange water, which never leaves a closed pipe system, goes through a heat transfer device similar .to a car radiator, through which air is forced by a fan. The heated air is channeled through the house by ducts. When the circuit is complete the spent exchange w a t e r is piped back down the well to be - ilslf. reheated and the cycle repeats itself. The water also heals the home's tap water in a pipe- within-a-pipe arrangement tha eliminates the need for a con ventional water heater. NEW GEOPHYSICAL THEORY Bowen says "a'new body o! geophysical theory points to two sources of hot water, botl virtually inexhaustible: natura decay of radioactive maleria in the earth's crust, and fric lion from migrating crusla plates. The crust is not the slalic lifeless shell it was one thought 'to be, but a dynami system of endlessly shifting plates, he says. The friction created by thi movement produces incredible amounts of heat, capable t, melting the surrounding bee rock to bubbling liquid that ex pands and seeps upwar through faults and fissures. This heat, combined with that from radioactive decay, is conducted upward through layers of rock. It heats reservoirs of ound water in its path to any times the surface boiling aint. But the water, under tons geologic pressure, doesn't »il. It remains liquid. A well tapped into such t. ·essurized chamber ot super eated water brings the liquid cketing to the surface like an 1 gusher. On contact wilh at lospheric pressure, it flashes r turns instantly to steam. Occasionally, the subterra ean water gets so hot it boils lousands of feet down and sur aces as dry sleam, packing lore pressure and generatin. lore power than wet steam roduced by flashing. The dry earn converts more readily t .ectrieity.

Bid For Games NAIROBI, Kenya (AP) -Kenya, Africa's leading track and field nation, is making a firm bid to stage the 19B2 Commonwealth Games in Nairobi. Isaac Lugonzo, chairman of the decision-making Kenya National Sports Council, said the Ken, r a Olympic Association had jeen entrusted with the advance work In connection with ;he Kenyan offer. KOA chairman John Kasyoka said five; other nations -- Nigeria, Australia, Trinidad and Tobago, India and Malaysia -have already indicated an interest in hosting the games, billed as a "mini-Olympics." If the Games are held here, they will be the first ever held on African soil since they were in- itiatd 44 years ago in Ontario. Democratic presidential nomi nation it is open to all comers. But even if Kennedy does not run, Udnll is competing against better-known Democratic prospects and at least two of them already are spending more money and traveling harder than he is. Sens. Henry M.

' : Kennedy has said publicly he would like to be president but that does't mean he'll run. Sens. Edmund S. Muskie ot Maine and Hubert H.
