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.

One possible scenario for the electricity system in the Western US in 2026-29. Under a range of resource cost scenarios, most coal power plants would be replaced by solar, wind, gas, and/or nuclear generation, with intermittent renewable sources providing at least 17% and as much as 29% of total power by 2030.

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.

EPA proposes rule for nationwide 30% cut in GHG from existing power plants by 2030 relative to 2005

Green Car Congress

EPA is using four “building blocks” to determine state-specific goals: Reducing the carbon intensity of generation at individual affected electric generating units (EGUs) through heat-rate improvements. Lower the electric system’s overall carbon intensity by shifting generation among existing EGUs. Expanded lower-carbon generation.
