...energy imparted to the electrons by the radio wave is in the form of mass. As a result, each electron increases its mass 40,000 times, and has acquired about 20 billion electron volts (BEV) of energy by the time it reaches the far end of the copper tube. There, the extremely powerful stream of charged particles passes through a beam "switchyard," where giant electromagnets direct it into one or another of two target buildings, or split it between both...
...shortage will probably get worse before it gets better. Among other things, Zambia's political decision to stop shipping copper through Rhodesia creates a bottleneck that may by year's end leave 150,000 tons of Zambian copper awaiting transport. To copper producers, the great danger is that higher prices and uncertain supplies may cause copper users to switch rather than fight...
Some big customers are already looking for ways to cut copper requirements...
...gobbles copper, and so does prosperity. In the U.S., 13% of copper production is now reserved for Viet Nam military needs. At the same time, demand for color TV sets, appliances and cars has helped boost consumption 17% this year to a rate of 2,344,000 tons, nearly half of the metal's world output. With Europe and Japan also using more copper, the extra demand has come too fast to be met by producers plagued by strikes in Chile and by tensions between white Rhodesia and black Zambia...
...result is a world copper shortage and strong upward push on prices. Earlier this year the price rose to a breath taking 98¾? a lb. on the London Metal Exchange, a small-volume speculative market to which users turn when regular sources fail. In April, Chile, unable to resist temptation, broke a producers' agreement that had pegged the price at 42? a lb., went up to 62?. Zambia then decided to sell at L.M.E. prices, now 72?, and Peru-based companies followed suit. Last week Chile again hiked its price, this time...
