Concorde's air intake system, developed 40 years ago, is still leading-edge technology today. Flying at Mach 2—roughly 1,350 miles per hour—wind friction quickly raises the surface temperature ...

Radio amateurs often have a love-hate relationship with home-made inductors, sharing all kinds of tips and tricks as to how the most stable nanohenry inductor can be wound. But there’s another ...

The ventilation system is integrated nicely into the ... A higher value denotes better air circulation. Induction cooktops with downdrafts should have a minimum 300CFM rating.

This induction heater has a trick up its sleeve, too. Instead of using an air coil to generate heat in the cookware, this one uses an iron core instead. The project’s creator [mircemk] built an ...

Nowadays, for low-power and highly integrated electronic systems, embedded inductor-based SRs show several limitations that can be overcome by the use of inductorless SR architectures. This paper ...
