A new type of extinguisher that uses sound waves to put out fires has been built by two engineering students in the US. Both chemical- and water-free, the invention offers a relatively non-destructive method of fire control, which could find applications in fighting small fires in the home, and the researchers now hold a preliminary patent application for their device.
While the concept of using sound waves to extinguish flames is not new, previous attempts to realize the principle – including efforts by teams at West Georgia University and the US Defense Advanced Research Projects Agency (DARPA) – had not been successful.
Undeterred by this, as well as initial [...]
That may explain why 42% of America’s major urban highways remain congested, costing the U.S. economy an estimated $101 billion in wasted time and fuel annually. And pollution wasn’t even factored into the equation.
How much capital would be needed to significantly improve U.S. road conditions? About $170 billion, according to the Federal Highway [...]
Generating electricity with a bicycle seems like a natural combination: tap some of the energy that goes into turning the wheels and convert it to power to light your way. Miami startup Spinetics takes that idea to the next level with the CydeKick, a generator that not only powers lights, but also charges USB devices such as phones, cameras and GPS units on the fly.
At the same time, the generating process has been improved to cause less drag on the wheels.
The Cydekick Pro consists of a wheel-mounted generator and a handlebar-mounted headlight and USB charging unit, all of which can be installed by the user. An optional taillight accessory is available as well. The [...]

Talkitt is the winner of the 2015 Edison Gold Award for Verbal Communication. It is the only solution that enables people who have speech disabilities due to motor, speech and language disorders to easily communicate using their own voice. The Voice2Voice application translates unintelligible pronunciation into understandable speech and runs on any mobile or wearable device allowing the person to communicate freely, anywhere.
With Swiss pilot André Borschberg at the controls, the solar-powered, single-pilot Solar Impulse 2 airplane took off from Nanjing Lukou Airport in China today bound for Hawaii on the longest leg of its round-the-world flight.
This isn’t just a major leg of the Solar Impulse 2 solar-powered circumnavigation, it is also an attempt at the longest duration flight ever by a solo pilot in any type of aircraft. Confined to his cockpit not much larger than a first class airline seat, Borschberg will be in the air for 130 hours, or about five nights, as he flies 8,172 km (5,078 mi) on his way to the Hawaiian Islands. During this time, he will be in constant contact with [...]
