...apartment buildings. He is also developing a smaller model, the size of a flashlight, that he hopes to market for homeowners and motorists at $50 to $100 each. Now Cottell is experimenting with a new emulsion that will consist of 55% oil, 30% water and 15% sludge, the slushy sediment produced by partially treating sewer wastes. Recycled sewage, he says, may well be a fuel of the future...
...dryer needs almost ten times as much. A standard hot water heater burns 4,219 kwh. annually, v. 4,811 kw-h., or $110.17 worth for a deluxe, quick-recovery model. Opening the tap at the base of most water heaters at least monthly drains out heat-robbing sediment...
Died. Dr. Hans Albert Einstein, 69, son of the late famed physicist, and a professor of hydraulic engineering at the University of California at Berkeley, who was best known for his researches into the transportation of sediment in flowing water; following a heart attack; in Falmouth, Mass...
Trudged. Trudging, a moving upstream in a steep riverbed; the sediment becoming softer and deeper, the further one goes. This is her motion, now, walking; her motion in life always, these days. Invisible fetters are wrapped around her limbs; her arms and legs; flimsy but horribly restricting. To move at all is a victory. To appear to move 'normally', miraculous. She sees the same gentle restraining threads on everyone; scarf-like chains on every person near her; even threaded to their roving eyes. She sees them and smiles, feeling tired. Her walk slows. There are moaning pains in her toes...
Writing in Science, Emiliani reports that the earth has undergone at least eight periods of extreme cold and seven of torrid heat in the past 400,000 years. His conclusion is based on cores of ocean sediment from the Caribbean. Composed of the remains of tiny sea animals, the layered sediment provides a record of climatic changes. When the oceans warm up, there is a decrease in the ratio of the isotope oxygen-18 to ordinary oxygen in the shells of the little creatures; when temperatures go down, the concentration of oxygen-18 goes up. Moreover, the proportions are preserved...
