...Brick and masonry homes with metal framing do not burn. Wood is the culprit - the fuel for fire. Building-permit rules should disallow the use of wood in all new construction. Communities in fire-prone areas should also think about stocking forested and undeveloped lands with goats. These creatures could devour the underbrush that dries and fuels firestorms. Firefighters could better spend their time tending the goats than periodically risking their lives on uncontrolled fires. The goats could become part of the firefighters' arsenal, as important as trucks, hoses and protective gear. Incentives from insurance companies could help defray...
During the week, Gupta uses the plane to train engineering students and flight attendants. On weekends, under the billing Aeroplanet, it is open to the public and school groups. Poor villagers and students can visit free. "Passengers" check in, receive boarding passes and climb a steep metal staircase to enter the plane. Flight attendants then run them through the safety procedures, serve them snacks and cold drinks and answer questions about how an aircraft works. In a nod to a more innocent time, passengers are free to visit the pilots in the cockpit. "We are fulfilling life wishes," says Gupta...
...saving bits of energy and environment here and there add up, then Finland's Enfucell has a battery that will help people make a difference by cutting down on all the metal, lithium and alkaline that leaks from conventional cells. "Our battery doesn't have to go to the battery-recycle bin. It's disposable as household waste," says Jaako Happonen, 50, Enfucell's chief executive...
...paper. Its SoftBattery works much the same way as ordinary "button" batteries (like the one in your watch) and "finger" batteries (think AA). Ions travel from an anode, pass through a solution called an electrolyte to a cathode and emerge as an electrical charge. Instead of running ions through metal casings full of toxic and corrosive substances like lithium and alkaline, Enfucell uses a thin paper sheet as a conduit. It pastes one side with zinc and the other side with manganese dioxide. Ions flow through an electrolyte solution of water and zinc chloride within the paper...
