GreenDisk: a viable e-waste solution?
April 1, 2008 09:11 AM - , Triple Pundit

Computers are becoming cheaper and easier to manufacture by the minute. Intel's new Atom processor is bound to create a whole new set of net-enabled devices at extremely low cost. While the processor is not out yet and prices are not set in stone, rumors price new "net-top" computers below $200. Cheaper computers make electronic recycling all the more relevant. Computers and gadgets are being replaced more frequently as electronics become obsolete in a matter of months.

EPA criticized over new lead paint rule
April 1, 2008 12:20 AM - Reuters

WASHINGTON (Reuters) - The U.S. Environmental Protection Agency offered a new rule on Monday aimed at shielding children from the risks of lead-based paint, but a watchdog group said the rule needs to be tougher.

Ordered by Congress in 1992, the rule takes effect in April 2010.

Invention: Diamond-cooled nuclear reactor
March 31, 2008 09:37 AM - New Scientist

Nuclear plants can fail when the heat from the reactor is not removed quickly enough from the core. This can happen in pressurised water nuclear reactors if the water in the cooling system boils, because steam is a much poorer conductor of heat than liquid water. These reactors have a primary water cooling system that directly takes heat away from the reactor. It is sealed under huge pressure to prevent it boiling and conducts heat to a secondary water cooling system that is not sealed.

Susan Greenfield and her girlfriend Llina Kempner couldn't wait for their new memory-foam mattress top to arrive. For months, they'd heard friends rave about how the high-tech material molds itself to your body. But when they unwrapped the three-inch-thick pad in their Manhattan apartment, they noticed a strong, acrid odor. "My nose and my lungs were miserable," recalls Greenfield. For the two nights Kempner slept on the mattress top, she felt nauseated. After Greenfield, who is chemically sensitive, had an asthma attack in the middle of the night, the couple returned the mattress pad. But its stench lingered in the apartment for weeks.
