Engineers at Los Angeles' McCulloch Corp. believe that they may have found a solution. In an effort to improve McCulloch's portable electric-starting chain saw, they developed a new method of recharging ordinary nickel-cadmium batteries - the same as those used in transistor radios, electric toothbrushes and other household appliances. Ordinarily, it takes as long as twelve to 15 hours to recharge such batteries from wall out lets. With their system, say the McCulloch engineers, the job can be done in ten to 15 minutes...
...crystalline waters that tumble from Alps near Reichenau, Switzerland, are choked with wastes by the time they pour into the North Sea, 820 miles away. At Basel, the Rhine picks up city sewage; the chemical industries near Mannheim dump acids, oils, phenols, ammonia, dyes, chlorine, sulphate, iron, copper, bleach, cadmium and formaldehyde into its waters; the coal mines near the confluence of the Ruhr disgorge calcium deposits and sludge; the steel mills of Cologne contribute iron dross, furnace slag, oils and fats. As a result, the Rhine has come to be known as "Europe's longest sewer...
...would have a total of 53 stations where their batteries could be recharged. The floor of Caltech's minibus was covered with 20 lead-cobalt batteries, on top of which were pads where off-duty drivers slept. M.I.T.'s team borrowed a set of $20,000 nickel-cadmium batteries. Characteristically, the engineers used linear equations to work out a handicap system...
Quick Zap. A.M.C.'s hopes rest on a piggyback system of two 25-lb. nickel-cadmium batteries and two 75-lb. lithium batteries being developed by Gulton Industries of Metuchen, NJ. The lithium batteries are for sustained speeds, can store 15 times as much energy per pound as lead-acid batteries now used in conventional cars. For quick acceleration-a safety factor lacking in present electric-car designs-the nickel-cadmium batteries would cut in briefly, could zap the car from a standstill to 50 m.p.h. in 20 seconds. And for longer battery life between charges, the Amitron would...
...into the lungs than it could on its own; without particles to carry it, the gas can be exhaled relatively easily from the upper respiratory tract. Other participates act as catalysts in the atmosphere, speeding the conversion of sulphur dioxide into more harmful sulphuric acid. Particles of arsenic, beryllium, cadmium, lead, chromium and possibly manganese, discharged into the atmosphere by a variety of man-made processes, may contribute to cancer and heart disease...
