Americans Still Held Hostage in Algeria
“One American has died in the
Algerian hostage crisis, according to
Associated Press sources.
The State Department confirmed
earlier Friday that Americans are still being held hostage at the Algerian gas factory seized by Islamists earlier this week, though the number of hostages being held is unclear. United States officials said they will not participate in any kind of exchange with the terrorists to free the Americans. “
” Build a plane that’s as heavy as a car, but uses only as much energy as a scooter. And stay aloft with just the energy of the sun—even after sunset. That, pilot André Borschberg says, is the challenge facing the Solar Impulse team as it stares down its biggest challenge yet: flying around the world in a solar-powered plane.
You might have heard about Solar Impulse when the sun-powered plane project made its maiden flight in 2009, or in 2010 when Borschberg set the endurance record by piloting the aircraft for 26 consecutive hours, running on stored solar energy from on-board batteries after the sun went down. Now he and teammate Bertrand Piccard are off on even more ambitious ventures, which they came to New York to discuss last night. First, in 2013, they will fly their solar-powered plane across the United States. Then, in 2015, they will pilot a larger version around the world. “

” These changes in the law are going to demand that we change the way we think about lightbulbs. We’re accustomed to a lightbulb being a minor expense, but the upfront cost of an energy-efficient one is much higher. Some might cost $30 or more per bulb.
CFLs represent the best value for consumers, as they use one-fourth the power of a comparable incandescent lightbulb and last up to 10 times longer. As a result, each CFL will save the consumer at least $30 in the form of lower electricity costs over the life of the bulb. “
But There Is More To CFLs Than Energy Savings …
” Compact fluorescent lightbulbs contain a minuscule amount of mercury, and you can’t safely ignore potential contact with it .
Lightbulbs break all the time. So why would a single broken bulb in a Maine household trigger the state’s Department of Environmental Protection to refer the homeowner to a decontaminator?
The answer lies in the type of bulb that broke—a compact fluorescent lightbulb—and what was inside that bulb. Compact fluorescents, like their tubular fluorescent precursors, contain a small amount of mercury—typically around five milligrams. Mercury is essential to a fluorescent bulb’s ability to emit light; no other element has proved as efficient.
As effective as it is at enabling white light, however, mercury—sometimes called quicksilver—is also highly toxic. It is especially harmful to the brains of both fetuses and children. That’s why officials have curtailed or banned its use in applications from thermometers to automotive and thermostat switches. “
