An induction heater operates by surrounding the object to be heated with a coil carrying high frequency AC current. Basically, the entire setup acts like a huge transformer with a shorted secondary.

Single-atom transistors are also the limiting point for Moore's law, where miniaturization can go no further. So fabricating logic circuits from these transistors will bridge the world of silicon ...

Miniature self-sensing transistor thermostats use a single transistor (BJT or FET) to serve as both a temperature sensor and stabilizing heater. These transistor thermostats are (when well designed) ...

Elaborate production methods would initially prevent single-atom phosphorus transistors from being a worthwhile addition to traditional computers, but they may be necessary one day.

Transistors consisting only of several-atom clusters or even single atoms could become the building blocks of a new generation of computers with unparalleled memory and processing power. But first ...

Induction cooktops use electromagnets, conductors, resistance and high-frequency currents to fry eggs at warp speed. Here's how they work.
