...unexpectedly grim unemployment numbers released yesterday. While the rate increased only slightly to a 26-year high of 9.5 percent, from 9.4 percent, the raw numbers led many to warn that economic recovery isn't on the horizon. The U.S. economy lost 467,000 jobs in June, marking the first time the monthly losses increased after they had been steadily shrinking from the January peak of 741,000....In addition to the basic unemployment rate, everyone points to worrying signs from the so-called underemployment rate, which includes part-time workers who can't find full-time work and those who have given up looking, that has increased to 16.5 percent.
That may only be one-tenth of a percentage point higher than the previous world-record holder, but it's the first advance in 21 years. Commercial silicon solar cells are much cheaper than GaAs, but have an efficiency of just 10 to 12 per cent and are also bulkier. The Quantasol device can cope with much brighter light without becoming overloaded, making it possible to use a very small solar cell to absorb light collected by a system of cheap lenses and mirrors.
