The best use of the sun's energy is to make hydrogen, according to a Duke University researcher. Engineer Nico Hotz earlier this week detailed results from his research around a rooftop solar panel that generates hydrogen from the sun's heat. The hydrogen gas--which is made by breaking off hydrogen atoms from a water solution--can be stored and used to make electricity in a fuel cell. In his experiment, Hotz determined that his system creates more usable energy than solar photovoltaic panels which convert sunlight directly into electricity. He calculated the cost could be lower, too. There have been research efforts--and a commercial product from a company called Nanoptek --to make hydrogen from sunlight. Hotz's system, though, uses a new technique that relies on methanol, also known as wood alcohol, and a nano-engineered catalyst. Under the glass of Hotz's solar collector are copper tubes, coated with aluminum and aluminum oxide, which carry water and methanol. Once the liquid is heated to a sufficient temperature, a catalyst is added to cause hydrogen atoms to break off. That hydrogen gas is then piped and pressured for storage in a tank, where it can be drawn on to make electricity in a fuel cell.

Ford and solar-panel maker SunPower have created a solar-powered electric-car package. Buyers of Ford's electric vehicles will have an option to have SunPower's rooftop solar panels installed for about $10,000 after a federal tax rebate. The companies estimate that the 2.5-kilowatt array will generate enough juice, about 3,000 kilowatt-hours a year, to fuel acar for about 1,000 miles a month of driving. The "Drive Green for Life" program means drivers can cut the cord on fossil fuels by generating power during the day and charging at night, according to the companies. Ford plans to release an all-electric Ford Focus and its C-Max Energy plug-in hybrid in 19 states next year and in Europe in 2013.

They can look benign from a distance - solar panels glistening in the sun or turbines gently churning with the breeze to produce electricity for hundreds of thousands of homes. But building and maintaining them can be hazardous. Accidents involving wind turbines alone have tripled in the past decade, and watchdog groups fear incidents could skyrocket further - placing more workers and even bystanders in harm's way - because a surge in projects requires hiring hordes of new and often inexperienced workers. Last year, the solar industry grew 67 percent and doubled its employment in the U.S. to 100,000 workers, according to the Solar Energy Industries Association. The wind industry supports more than 75,000 jobs. "We're hearing about more and more incidents," said Lisa Linowes, executive director of watchdog organization Industrial Wind Action Group. "One of these days, a turbine's going to fall on someone." Many wind turbine technicians work in a bathroom-size space 20 stories above ground surrounded by high-voltage electrical equipment. Some inspect turbine blades while suspended alongside them, on sites whipped by strong winds. Components can weigh more than 90 tons.
