Will Urban Air Mobility ‘Take Off?'

A Tech Briefs TV video demonstrates NASA’s rotary-wing “air taxi” concept. The vehicles, in theory, have the capacity for vertical take-off and landing, eliminating the need for long runways.

In 2015, Chris Valasek and Charlie Miller demonstrated a hack of the Jeep Cherokee. Valasek tells Tech Briefs what has changed since then.
Don’t hold your breath, says Jeff Crystal from Voltaic Systems.

Imagine a world where cell phones and laptops can be charged in a matter of minutes instead of hours, rolled up and stored in your pocket, or dropped without sustaining any damage. It is possible, but the...

Fuel cells generate electricity directly from hydrogen and oxygen and produce only water vapor as emissions. But most fuel cells are too expensive,...

Question of the Week: Aerospace
How Strong is the ‘Ionic Wind?’

MIT has built the first-ever plane with no moving parts. Instead of turbine blades, propellers, and fans, the aircraft relies on an “ionic wind” — a silent but strong flow of ions, produced onboard, which generates enough thrust to propel the plane over a sustained, steady flight.

Low-Light Night Vision Imaging and Video Capture

Conventional night vision goggles all use image intensification (I2) tube technology that multiplies ambient, visible, and near-infrared light several thousands of times, allowing a user to see and operate in very-low-light conditions. One shortcoming of I2 tube night vision devices is that they...
