Taking the Measure of the Earthquake That Destroyed Tokyo

Cars That Think

In Tokyo, the fires merged into a firestorm so intense that it created its own wind system and set alight the city’s many wooden buildings. Palmieri’s seismograph consisted of U-shaped tubes filled with mercury. When the ground shook, the mercury would close an electrical circuit and stop an attached clock.

The Birth of Random-Access Memory

Cars That Think

Over the years, memory has been made up of vacuum tubes, glass tubes filled with mercury and, most recently, semiconductors. Williams , Tom Kilburn , and Geoff Tootill developed and built the machine and its storage system—the Williams-Kilburn tube—at the University of Manchester. One such researcher was British engineer F.C.

Generating Power on Earth From the Coldness of Deep Space

Cars That Think

On the rooftop of a quiet building, a set of panels cools the rooms within and keeps the lights on, removing heat and generating electricity using the coldness of the sky. That cold isn’t in the air around the building—the night is warm. It’s a summer night. Sound crazy? Admittedly, this technology isn’t fully available just yet.
