A dead satellite can become a high-speed hazard in an orbit that is already packed with working spacecraft. That risk is why ...

If you have an interest in audio there are plenty of opportunities for home construction of hi-fi equipment. You can make yourself an amplifier which will be as good as any available commercially, and ...

How electronic charge is distributed over a molecule determines to a large extent its chemical properties. Here, we demonstrate how the electrostatic force field, originating from the inhomogeneous ...

Electrostatic motors are now common in MEMS applications, but researchers at the University of Wisconsin and spinoff C-Motive Technologies have brought macroscale electrostatic motors back. [via ...

A British audio speaker company claims its in-vehicle sound technology can boost range for electric vehicles with lighter weight and less energy consumption. The "electrostatic speakers" can ...

The original version of this story appeared in Quanta Magazine. Imagine, for a moment, that you’re a honeybee. In many ways, your world is small. Your four delicate wings, each less than a centimeter ...

Car hi-fi speakers are heavy, bulky and wasteful of power. Packaging the speakers in the doors or dash is a headache. So is getting rid of the heat they generate. Now imagine a speaker that isn’t a ...

What if the very principles that have powered industry for over a century were suddenly turned on their head? For decades, electromagnetic motors—reliant on copper windings and rare earth magnets—have ...

Whether you're a casual gardener or someone who needs to disinfect surfaces frequently for their actual job, you may have encountered the need for a sprayer at some point. In the past, all kinds of ...

Ferroelectric fluids use a strong transverse electrostatic force to climb 80 mm, enabling lightweight, low-voltage motors and compact energy-efficient actuators. (Nanowerk News) Researchers have ...

Electrostatic precipitators (ESPs) have been used for over 100 years to remove entrained solid particulates or fine mists from gas flows in the power, cement, metal production, paper, and other ...
