1/2 the World's New Buildings are Built in China

(source: Popular Science, 8/07)

China has built the equivalent of the U.S. highway system in a decade, and has surpassed the U.S. to become the world's #1 emitter of green house gases. By 2025, 400M Chinese will move from the countryside to the cities - the largest migration in world history. China is seeing a 10% increase in GDP each year - 2x that of the U.S. during the DotCom boom. It adds the electricity use of Norway to its grid every year. China last year produced 2.3B tons of coal, more than the U.S. and Russia combined. China made 8% of world's emissions in 1980, up to 18% by 2004. It is home to 7 of the world's 10 dirtiest metropolises.

Fly Nepal Airlines...

and Leave the Sacrificing to Us

(source: AirWise News)

Officials at Nepal Airlines, Nepal's state-run airline, have sacrificed two goats to appease Akash Bhairab, the Hindu sky god, following technical problems with one of its Boeing 757 aircraft.

The goats were sacrificed in front of the troublesome aircraft at Nepal's international airport in Kathmandu in accordance with Hindu traditions, an official said.

Everybody wins here: They avoid costly  maintenance procedures and pass the savings on to you.

Windows Up or Down?

A study published by Duke Energy purports to put to rest the debate over whether it is more efficient to drive with your car windows down w/o the AC on, or to roll them up and run the AC.

The verdict:

AC off = better mileage

AC on = worse mileage

As with most rules of thumb, there are exceptions, like for highly streamlined sports cars whose aerodynamic efficiency depends on the total body configuration.

Think Your Electric Utility Bills Are Shocking?

(source: USA Today)

Following deregulation and lifting of rate freezes, one couple in St. Louis, IL, got a bill for $1,024.31, up from $172 a few months earlier. This is happening all over the country. Here are some recent rate increases:

State Change from 2002 to 2006
Texas 57.7%
Mass. 55.6%
Conn. 53.2%
Rhode I. 47.9%
Florida 36.8%

D.C. 23.8%
U.S. Avg. 23.3%
It is a good thing for the bureaucrats that this is not figured into inflation numbers.

About RF Cafe

Webmaster:

    Kirt Blattenberger,

    BSEE - KB3UON

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
