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.

Bromine then reacts with a gaseous form of mercury, turning it into a pollutant that falls to Earth’s surface. In the spring of 2008, satellites detected increased concentrations of bromine, which were associated with a decrease of gaseous mercury and ozone.

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.

Another example of this effort is Honda’s Russells Point, Ohio, transmission plant, which is the first auto plant in America to utilize on-site wind power for a substantial portion of its energy use.
