Dousing Flames with Low-Frequency Sound Waves

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 [...]

Precision Nanobatteries by The Billions

Tiny batteries formed inside nanopores demonstrate that properly scaled nanostructures can use the full theoretical capacity of the charge storage material. These nanobatteries delivered their stored energy efficiently at high power (fast charge and discharge) and for extended cycling.

Precise structures can be constructed to assess the fundamentals of ion and electron transport in nanostructures for energy storage and to test the limits of three-dimensional nanobattery technologies.

Nanostructured batteries, when properly designed and built, offer promise for delivering their energy at much higher power and longer [...]

Renewable Energy from Evaporating Water

An immensely powerful yet invisible force pulls water from the earth to the top of the tallest redwood and delivers snow to the tops of the Himalayas. Yet despite the power of evaporating water, its potential to propel self-sufficient devices or produce electricity has remained largely untapped — until now.

Laser-Arc Coating vs Friction

Coating engine components with hard carbon reduces friction to almost zero – a development that could save billions of liters of fuel worldwide every year. Now researchers have developed a new laser method to apply the coating on the production line

Scientists already know how to coat components with diamond-like carbon to minimize friction. But now Fraunhofer researchers have developed a laser arc method with which layers of carbon almost as hard as diamond can be applied on an industrial scale at high coating rates and with high thicknesses.

By applying carbon coatings to engine [...]

Tesla Energy is Elon Musk’s Battery System That Can Power Homes, Businesses, and The World

Tesla has finally taken the wraps off Tesla Energy, its ambitious battery system that can work for homes, businesses, and even utilities. The system breaks down into two separate products: the Powerwall is a home battery system, that comes in a 10 kWh version for $3,500, or a 7 kWh model for $3,000, excluding installation and the inverter. The unit is about three feet by four feet in size and six inches thick, and comes with integrated heat management and can fit either on the inside or outside of the wall of your home.

The system is connected to the internet — Elon Musk said that the system can be used to create “smart microgrids” — and can be used as a redundancy [...]

Adopt a Cloud Server and Heat Your Home for Free

Data centers may be out of the public eye, but 17 percent of technology’s overall carbon footprint is due to their work. Some of the largest data centers host hundreds of thousands of running servers and sit on hundreds of acres of land. In the US, which hosts approximately 40 percent of the world’s data centre servers, it is estimated that server farms consume close to 3 percent of the national power supply. All these servers produce massive amounts of heat, and their cooling requires more massive amounts of energy. While big companies like Google, Facebook, and Microsoft are looking into a variety of ways to make the cooling process greener, one particularly clever solution is coming [...]

Fracking is building up a disaster waiting to happen in oil-rich Oklahoma

At first glance the small town of less than 8,000 inhabitants looks like typical country America, the kind of place that John Updike might once have written about. Except Cushing, in north-east Oklahoma, is very different.

Moses Lake Inventors Unveil Engine Enhancer

Mike Archer and his team at A PADLE say their new combustion engine enhancer can help lower engine emissions, decrease fuel consumption and increase engine life and engine power. Together, Archer, Keith Simpson, Bill Plonske and Eli Kliemonv, have spent the last seven to eight years perfecting the technology. Their engine enhancer breaks down water molecules into hydrogen and oxygen gas which is highly combustible and causes fuel in an engine to burn more completely. HHO generators already exist, but the ones currently on the market are flawed mostly because they use a catalyst to extract the hydrogen and oxygen gases from water, said Simpson. That can lead to units producing an excess [...]

Researchers Discover N-type Polymer for Fast Organic Battery

Researchers at the Univ. of Houston have reported developing an efficient conductive electron-transporting polymer, a long-missing puzzle piece that will allow ultrafast battery applications.The discovery relies upon a "conjugated redox polymer" design with a naphthalene-bithiophene polymer, which has traditionally been used for applications including transistors and solar cells. With the use of lithium ions as dopant, researchers found it offered significant electronic conductivity and remained stable and reversible through thousands of cycles of charging and discharging energy.The breakthrough, described in the Journal of the American Chemical Society, addresses a decades-long [...]
