We write a lot about Unmanned Aerial Vehicles (UAVs) in military use but, as is so often the case with technology developed for the military, this kind of equipment is increasingly finding its way into civilian applications. The latest example to catch our eye is the Flying-Cam III E Special Aerial Response Autonomous Helicopter (SARAH) – a fully electric quasi-UAV camera platform for getting those majestic soaring shots for film and television shoots.

Got a last-minute hot date? Meeting with the boss? Getting snide comments about your ‘porn star mustache’? Or just couldn’t be bothered? Whatever your reason for needing a quick shave at work, the Thanko USB Electric Razor is your savior. Just plug it into the USB port on your computer, and whiskers-be-gone. And if your monitor’s nice and shiny, who needs a mirror? Read More

Renault will show four new electric vehicle concepts at next week’s Frankfurt Motor Show, previewing what is expected to become a new Zero Emission product range from the French manufacturer. No details of the four cars have been made available, but sketches of the four vehicles have been released showing them from above, and the most exciting concept appears to be a very small and narrow single seat four-wheeled personal transport concept (pictured). Check out the from-above images of all four vehicles inside. Read More

Idaho-based Solar Roadways founder Scott Brusaw is excited that his company has a received a USD$100,000 U.S. Department of Transportation (DOT) grant to develop further his prototype that turns roads in giant electricity-generating solar panels. Apart from providing energy to power our homes, street lighting and so on, the roads could contain thousands of embedded LEDs to provide better street signage and make driving safer. He also believes the solar panel roads could last up to three times longer than the current petroleum-based asphalt surface and even be heated in winter to discourage dangerous ice build ups.

Indian electric car company REVA will unveil two new electric cars at the forthcoming Frankfurt International Motor Show (IAA) on September 16. The REVA NXR is a four-seater, three-door hatchback family car aimed at urban drivers while REVA’s showcar, the NXG, is a sporty two-seater with a targa roof that was designed by Dilip Chhabria of internationally-renowned automotive design company DC Design. REVA says it has added a unique technology to its cars that addresses ‘range anxiety’ – worrying about running out of charge mid-journey. The REVive telematics technology acts like an invisible reserve fuel tank. Drivers telephone or SMS REVA for an instant remote top-up should they run out of charge. At present, details are scarce about how REVive actually works but REVA assures us all will be revealed at IAA. Read More

So what do you do when you challenge yourself to come up with a design to make traveling around busy, congested cities as easy and stress-free as possible? According to the folks behind the YikeBike - which was officially launched at Eurobike 2009 trade fair in Friedrichshafen Germany this month - you start with a blank sheet of paper, throw a good-sized front wheel in for stability, swap pedals for a brushless electric motor and abandon the familiar forward-leaning riding position of the bicycle altogether.

The race to provide ecologically responsible mobility is on and Korean giant Hyundai is preparing an interesting range for the Frankfurt Motor Show with the first showing of the ix-Metro (pictured) and i10 Electric. The ix-Metro is a Hybrid Electric CUV for the European sub-B segment and the i10 Electric is a production-ready plug-in 49kW electric vehicle set to go on sale in Korea in the second half of 2010 with a range of 100 miles and top speed of over 80 mph.

As part of man's ongoing quest to extract the greatest benefits from solar power, Salt Lake City-based company Ceramatec, the R&D arm of CoorsTek, has made what it believes to be a massive breakthrough in batteries for storing energy harnessed from the sun. The company is making impressive inroads on the prototype of a deep storage battery, the size of a small refrigerator, that safely operates at room temperature, consists of everyday materials, and can output household power at 2.5c per kWh. What’s more, Ceramatec says it will be cheap to purchase. Read More

It's fascinating to think that while Edison and Tesla battled over the ascendancy of AC versus DC, most of the world didn't think this electricity thing was going to take off - I mean, who was going to spend trillions of dollars rolling out great coils of copper wire to bring this thing to the masses? Nikola Tesla was thinking along the same lines, and the Serbian genius's mysterious Wardenclyffe Tower was to be an experiment in beaming electricity wirelessly across the world, eliminating the need for a wired power grid altogether. But wireless electricity has been enjoying a cautious revival in the past decade - mainly at short distance and for reasonably trivial applications like charging cell phones and other battery-powered equipment. And as Eric Giler's great ten-minute demonstration at this year's TEDGlobal shows, wireless power seems very close to breaking through into the mainstream market. Read More
