Good thinking

Two brunettes and a blonde are driving in the desert when, all of a sudden, their car breaks down.

As none of them have any motoring knowledge, they decide to walk. Each of them decides to take one thing with her.

The first brunette takes some food in case she gets hungry, the second brunette takes some water in case she gets thirsty and the blonde takes a car door.

When questioned about her choice, the blonde replies:

"Well, if I get hot, I can roll down the window!"

Solar power plant

In 1980, the first U.S. government solar power plant was dedicated. It is sited in the sunny desert at Natural Bridge National Monument, Utah, and at the time the world's largest. An array of over 250,000 solar cells arranged in 12 long rows provides up to 50 kilowatts of power. The plant provides elecricity for the park's visitor center, staff residences, maintenance facilities and water sanitation system, which were otherwise 38 miles away from the nearest alternate power line. The power plant was part of a joint venture of MIT's Lincoln Laboratory and the Dept. of Energy. Huge batteries provide power at night and on cloudy days. A backup diesel generator automatically takes over if the batteries are drained too low. Its use is far less than the one the solar panels replaced, saving noise, exhaust pollution and fuel cost.«
