The team behind the Tortuga are looking to take the sport of trike drifting up a notch

Trike drifting, a sport that originated in New Zealand in 2009 and has since spread all around the globe, is typically the plaything of adrenaline junkies with long and winding downhill runs at their disposal. Drift-enthused DIYers have further indulged their taste for sideways movement by fixing motors to their rides, making it possible to slip and slide over flatter terrain. The Florida-based Tortuga Trikes is looking to take things up a notch, whacking a 6.5 hp (4.8 kW) motor on the back to bring the hobby a little closer to a drift car experience.  Read More

MIT proposes building floating nuclear power plants located 5 to 7 miles into the ocean, e...

The most frightening part of a tsunami hitting a nuclear power plant is what comes after – radioactive leaks that contaminate the water around the plant are exceedingly difficult to contain. The clean up of the radioactive water around the Fukushima Daiichi nuclear plant in Japan, which was struck by a tsunami in 2011, is expected to take decades. MIT researchers have come up with an alternative; they propose building floating nuclear plants, far enough offshore to simply ride out a tsunami and emerge unscathed.  Read More

Festo has applied the same methodology used in its robotic SmartBird to harvest energy fro...

Back in 2011, Festo created a natural-flight mimicking bionic seagull with flapping wings dubbed SmartBird. The company is now looking to apply similar principles in order to convert wind power into electricity with its DualWingGenerator system.  Read More

The BuffaloGrid is a solar charging hub for mobile phones

Mobile phones have proven invaluable for connecting communities in developing countries where there is no wired telecoms infrastructure. Often, however, there is no electricity infrastructure either, making device charging problematic. BuffaloGrid solves this by providing solar charging hubs to communities, and sharing its profits.  Read More

A rubber mat forms the 'carpet,' and sits atop a grid of hydraulic actuators, cylinders an...

Many organizations around the world are looking at ways to harness the power of waves as a renewable energy source, but none are covering quite the same ground as a team of engineers from the University of California (UC), Berkeley. The seafloor carpet, a system inspired by the wave absorbing abilities of a muddy seabed, has taken exploring the potential of wave power to some intriguing new depths.  Read More

An inexpensive high capacity organic battery has been developed by Professor Michael Aziz ...

Researchers at Harvard have developed an inexpensive, high capacity, organic battery that uses carbon-based materials as electrolytes rather than metals. The researchers say the technology stands to be a game-changer in renewable energy storage by solving the intermittent generation problems faced by renewable sources, such as wind and solar. The battery offers large volume electricity storage not possible with solid-state batteries and at a fraction of the cost of existing flow battery technology.  Read More

Professor J.C. Chiao and his postdoc Dr. Smitha Rao of the University of Texas at Arlington have developed a MEMS-based nickel alloy windmill so small that 10 could be mounted on a single grain of rice. Aimed at very-small-scale energy harvesting applications, these windmills could recharge batteries for smartphones, and directly power ultra-low-power electronic devices.  Read More

The small-scale prototype of the system

Among the concepts put forth for decreasing the range anxiety associated with electric cars, one is to embed electrical coils within the asphalt. This would allow vehicles to wirelessly draw power from the road as they traveled, although it would also involve having to tear up existing roads to install those coils. An alternative could be on its way, however. Scientists at North Carolina State University are developing a system in which power could be transmitted from stationary roadside stations to mobile receiver coils in cars passing by.  Read More

A group of researchers at NIST working with engineers from Colorado-based Scientech has developed a new approach to measuring laser power using a mirror and a scale. This method, which measures the force on the mirror driven by the radiation pressure of the laser light, presents a more rugged and more portable solution than current meters.  Read More

A newly developed silicon supercapacitor could allow for the seamless integration of energ...

A team of researchers at the Vanderbilt University in Nashville, Tennessee has designed a supercapacitor made primarily of silicon that has shown much improved power density over its commercially available alternatives. The advance could allow for interesting integration of battery technology in everyday electronics, from solar cells to smartphones.  Read More
