U.N. Kills Any Plans to Use Mercury as a Rocket Propellant

Cars That Think

A recent United Nations provision has banned the use of mercury in spacecraft propellant. Although no private company has actually used mercury propellant in a launched spacecraft, the possibility was alarming enough—and the dangers extreme enough—that the ban was enacted just a few years after one U.S.-based Mercury is a neurotoxin.

5 Big Ideas for High-Temperature Superconductors

Cars That Think

In 1911, Dutch physicist Heike Kamerlingh Onnes plunged a mercury wire into liquid helium and noticed that the wire’s electrical resistance vanished. But the materials could show up sooner in a wide array of practical applications, including wind power, energy storage, and nuclear magnetic-resonance machines.

This lithium-free battery startup just raised $78M in Series C funding

Baua Electric

The company’s first battery storage product is called Alsym Green, and it says it’s the “only high-performance, non-flammable option suitable for stationary and grid storage in situations where the risk of fire increases as the mercury rises.”

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.

Lotfi Zadeh and the Birth of Fuzzy Logic

Cars That Think

His career goal, for as long as he can remember, was to be an engineering professor. Rather, he thought of scientific and engineering research as a type of religion, practiced at universities. Zadeh received an electrical engineering degree from the University of Tehran in 1942. He doesn’t yell or scream.
