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. It refers to materials that superconduct above −195.79 °C, the boiling point of liquid nitrogen. The wire had become a “superconductor.” High temperature” isn’t room temperature.

Recent Hybrid Braking Complaints Highlight Regenerative Braking Design Issues

Green Car Congress

Likewise, a vehicle with a battery pack that happens to be near the upper range of its charge window (~70% to 80% for many hybrids) will also be limited in its ability to convert braking force to stored energy during a given braking event. Some early hybrid vehicles employed regen in tandem with a conventional hydraulic braking system.

In the NTSC standard, colors are determined by the phase difference between the color signal and a color reference signal transmitted at the beginning of each line.) Mercury News criticized the “flashbulb effect” noticeable during the swimming event. There are two basic modes in the Commodore 64: character-mapped and bit-mapped.
