Automobiles on Steroids

“This paper estimates the technological progress that has occurred since 1980 and the trade-o ffs that manufacturers and consumers face when choosing between fuel economy, weight and engine power characteristics. The results suggest that if weight, horsepower and torque were held at their 1980 levels, fuel economy for both passenger cars and light trucks could have increased by nearly 50 percent from 1980 to 2006; this is in stark contrast to the 15 percent by which fuel economy actually increased.”

Polynesian stick chart

“The Polynesians, scattered as they were over 1,000 islands across the central and southern Pacific Ocean, were master navigators who tracked their way over huge expanses of ocean without any of the complex mechanical aids we associate with sea fairing. They didn’t have the astrolabe or the sextant, the compass or the chronometer. They did however have aids of a sort, which though seemingly humble, were in fact the repositories of an extremely complex kind of knowledge. Called Rebbelibs, Medos. and Mattangs, today we call them simply Stick Charts.” Via Tecob. Related: Satellite navigation in the 18th century.
