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

Researchers are developing a real-life tractor beam, with the goal of pulling defunct satellites out of geostationary orbit ...

This remarkable miniature rotorcraft is so lightweight and efficient that it can lift its own mass given nothing but sunlight. The entire thing weighs about as much as four paperclips, and it can fly ...

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 ...

Over on his YouTube channel [Ryan Inis] has a video about how electrostatic motors are breaking all the rules. He explains that these days most motors are electromagnetic but suggests that may be ...

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 ...

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 ...

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 ...
