Colo. State Installs Lightning-Prediction System
s-orbital writes "According to Colorado State's Rocky Mountain Collegian, CSU has installed four ThorGuard Lightning Prediction systems for under $25,000 to help prevent a lightning-related death or injury on campus. Colorado has the third highest lightning death rate in the US, and this system provides up to 20 minutes of early warning by 'analyzing the electrostatic field within a two-mile radius of the device. When a set amount of lightning-producing electrostatic buildup is detected, a horn will sound and a yellow strobe light will begin flashing, signaling that people in the area should seek shelter because lightning is imminent.'" -

Wind Power Falls Under $0.01/kwh
js7a writes "Colorado State University's Rocky Mountain Collegian reports that, "as of June [the price of wind power] dropped to 1 cent per kWh." Even without further expected improvements in turbine technology, the U.S. would now need to use less than 3% of its farmland to get 95% of its electricity demand satisfied by wind power. Plus, wind power is the only mitigation of global warming, because if the whole world converted to wind power in 15 years, the amount of power being extracted from the atmosphere would be more than the increase in greenhouse gas atmospheric energy forcing since 1600. Don't say goodbye to coal and oil, yet, though; unless cell technology increases substantially, when we run out of oil we will convert coal to synthetic fuel." Update: 09/15 13:40 GMT by T : Note: the "1 cent" figure refers to the premium paid for the power over conventionally supplied electricity, rather than the final per-kWh price. -
