In 1911, Dutch physicist Heike Kamerlingh Onnes plunged a mercury wire into liquid helium and noticed that the wire’s electrical resistance vanished. One HTS induction heater now moving to commercialization rotates a metal ingot within a magnetic field to generate eddy currents within the metal. The wire had become a “superconductor.”

Upcoming electric passenger vehicles and light trucks from GM get most of the attention, but its new commercial EV brand is a quiet and very serious push too. Many US drivers now have a vague idea that General Motors is doing something with electric vehicles. But that was then, and this is now. Fastest development in GM history.

Over the years, memory has been made up of vacuum tubes, glass tubes filled with mercury and, most recently, semiconductors. Williams came up with the idea of using two CRTs, and storing the radar trace by passing it back and forth between the two. Without random-access memory, a computer today can’t even boot up.

But Electro didn't act on his idea, so he left in 1957 to start his own venture, Holt Instrument Laboratories , in his hometown: Oconto, Wis. Holt supplied calibration and measurement systems used for NASA 's Apollo, Gemini, and Mercury programs, and the company's devices are still used today. He retired from there in 1992.

Nor was 3M the first company to popularize magnetic media— that was Ampex , which commercialized the tape recorder in the late 1940s. military during the war, and the company revisited the idea immediately after. At first, the innovation didn’t spread outside of Germany because of World War II. The invention was used by the U.S.

Thermodynamics on Earth and in space Before we tell you about those ideas and prototypes, you need to understand the role radiation plays in maintaining Earth’s energy balance. The idea of using such a wavelength-selective emitter for radiative cooling dates back to the pioneering work of Claes-Göran Granqvist and collaborators in the 1980s.

government, and PurpleAir , created via crowd-sourcing of commercial sensors. The idea behind this motion event-triggered sensor isn't new. A hundred years ago, centimeter-scale tilt switches used a conductive blob of mercury rolling along a glass tube to close an electric circuit.
