Clip-on wind turbine aims to supplement solar panels

By - August 1, 2013 5 Pictures
Crowdfunding has come to the small wind generation field with an Indiegogo campaign intended for an interesting target niche: a small wind generator designed to be clipped onto solar panels. According to his pitch, Michael Ring has not only created a prototype, but calculated possible energy returns, targeted a price point and lined up suppliers for initial deliveries and has turned to Indeigogo to get his small startup off the launch pad.

PlugBook power strip can be hidden on a bookshelf

By - June 6, 2012 10 Pictures
Power cables are a necessary evil of technological life - until we all get wireless electricity - and while a tangled and fully loaded power strip is annoying, we always find there's something insanely irksome about trying to find your seemingly hidden (and equally tangled) 'spare' extension cord. Well, PlugBook is a power strip/extension cord which has been designed to look like a book ... so that it can be neatly stored on your bookshelf when not in use. Read More

RoboReel pulls in its power cord at the touch of a button

By - April 17, 2012 3 Pictures
The winding up of extension cords is something that most of us probably don’t give a lot of thought to – we loop them on the ground, spool them around our forearm, or perhaps use a spring-activated or hand-cranked winder. If you’re someone who spends a lot of time putting cords away, however, you might want to make the job safer and easier. That’s where Great Stuff’s RoboReel comes in. It’s a portable motorized cord winder, with some interesting features. Read More

Scientists successfully manipulate qubits with electrical fields

By - December 26, 2010 3 Pictures
Until now, the common practice for manipulating the electron spin of quantum bits, or qubits, – the building blocks of future super-fast quantum computers – has been through the use of magnetic fields. Unfortunately, these magnetic fields are extremely difficult to generate on a chip, but now Dutch scientists have found a way to manipulate qubits with electrical rather than magnetic fields. The development marks yet another an important development in the quest for future quantum computers, which would far outstrip current computers in terms of speed. Read More

New graphene-based single-transistor amplifiers are a triple threat

By - October 13, 2010 2 Pictures
Graphene has already brought us the world’s smallest transistortwice – and now the one atom thick form of carbon that recently won its discoverers the Nobel Prize has been used to create a triple-mode, single-transistor amplifier. The new transistor has the potential to replace many traditional transistors in a typical integrated circuit and its developers say the device could become a key component in future electronic circuits.

Mobile phones charged by the power of speech

By - September 20, 2010 1 Picture
In the search for alternative energy sources there's one form of energy you don't hear much about, which is ironic because I'm referring to sound energy. Sound energy is the energy produced by sound vibrations as they travel through a specific medium. Speakers use electricity to generate sound waves and now scientists from Korea have used zinc oxide, the main ingredient of calamine lotion, to do the reverse – convert sound waves into electricity. They hope ultimately the technology could be used to convert ambient noise to power a mobile phone or generate energy for the national grid from rush hour traffic. Read More

Electron switch could make thin, light, high-powered organic batteries a reality

By - September 16, 2010 1 Picture
There’s no arguing that batteries are an essential element of today’s electronics landscape. Without them our mobile devices would be a lot less mobile and we might still be crank starting our cars. The explosion in mobile electronic devices enabled by batteries and miniaturization has a major downside in the form of discarded batteries, the majority of which contain toxic heavy metals. Chemists have now discovered a new way to pass electrons back and forth between two molecules that could see the development of organic batteries that are lightweight and work without the need for toxic heavy metals.
