Harnessing waste heat to produce electricity
By Darren Quick
21:13 November 19, 2009 PST
That heat emanating from your computer as you sit reading this article amounts to nothing more than wasted energy. And your computer is not alone. More than half of the energy consumed worldwide is wasted, most of it in the form of excess heat. But new research at the Massachusetts Institute of Technology (MIT) indicates it might be possible to harvest much of the wasted heat produced by everything from computer processors to car engines and electric powerplants, and convert it into usable electricity. This kind of waste-energy harvesting might lead to mobile phones with double the talk time, laptop computers that can operate twice as long before needing to be plugged in to mains power, or energy plants that produce more electricity for a given amount of fuel.

Shelf car sunshade generates solar power
By Jeff Salton
21:58 November 16, 2009 PST
As the motoring world moves ever-closer to the welcome infiltration of electrically-powered cars, one thing holding them back is the availability of charging stations to “refuel” the vehicles which so far have an average range of around 120 miles between charges. The Shelf, a concept by Chinese designer Leon Zhu, takes advantage of the sun’s solar energy and collects enough of the stuff on a hot day to power the car’s air conditioner, tail lights and other electronic equipment, therefore extending the life of the car’s onboard batteries. What’s more, the solar panel protects your vehicle’s expensive duco from long exposure to the sun. Just don’t try to extend the solar panel while you’re driving. Read More
mPower Emergency Illuminator lights up after 20 years
By Jeff Salton
22:58 November 15, 2009 PST
Perhaps the best piece of advice I never got was "leave your flashlight in an obvious, easily accessible place”, because the one time you’ll really need it will be during a power outage or a blown fuse and the last thing you want at that time is wonder where the heck you put it. Oh, and keep it fully charged (you know why). While the mPower Emergency Illuminator won’t insist you keep it close by, it does have some impressive features – battery technology that will last up to 20 years (though not if you use it continuously) and a USB outlet which lets you charge other devices.

The Wall of Sound: the world's most powerful iPod dock unleashed
By Paul Ridden
02:51 November 5, 2009 PST
In a world where miniaturization rules the roost, it's refreshing to see some things getting bigger and bigger. Just last week we featured Regen's enormous ReVerb iPod dock which stands tall and slim at 35 inches (90cm). Now from Sweden comes the colossal 37.5 x 49 x 12 inch (95cm x 125cm x 30cm) "Wall of Sound", which can boom out 125 Watts of ground-shaking, tube-driven audio from its 28 speakers. Read More
Samsung STORY Station external drives cut standby power consumption to less than 1W
By Darren Quick
00:25 October 20, 2009 PDT
Samsung’s STORY Station drives will be the first 3.5-inch external hard drives to boast a standby power consumption of less than 1W. The typical standby power consumption of external hard drives is around 2.5W, so lowering that figure to 0.09W constitutes a reduction of more than 95 percent. The reduced standby power level easily meets requirements for the forthcoming European Union’s EuP (Energy Using Products) Directive for Standby Regulation, which is effective from January 2010.

Belkin's Conserve Surge helps reduce power consumption
By Jude Garvey
00:18 October 1, 2009 PDT
We first looked at Belkin’s Conserve Surge protector early last year. The company has just released a new version that includes a clever automatic timer to control power usage. The surge protector has eight outlets – two keep PCs and critical devices permanently on, while the other six outlets are automatically turned off after 11 hours. This allows you to power down non-essential office equipment at night and on weekends, saving valuable energy and money. Read More
Smart Grid City now online
By Paul Ridden
16:18 September 16, 2009 PDT
Boulder, Colorado has just become the world's first city to benefit from an intelligent power supply monitoring system. The Smart Grid City system aims to make outages easier to predict and/or prevent, manage power flow throughout the infrastructure and give customers greater access to energy information and more control over how much they use. Xcel Energy constantly monitors the grid network for any irregularities, allowing the company to fix problems before they happen. Read More
VW enters the home power market
By Paul Lester
21:28 September 15, 2009 PDT
Volkswagen has recently announced a rather ambitious project that, for a change, has nothing to do with cars. Teaming up with regenerative-power company Lichtblick, it aims to install 100,000 co-generation power units in Germany as part of a concept called ‘SchwarmStrom’ which, literally translated, means ‘swarm power’. Successful application would allow Germany to abandon the use of nuclear and coal power stations and provide adequate backup to renewable energy sources, reducing carbon dioxide emissions by up to 60%.

Really green power - running an electric circuit from trees
By Darren Quick
22:45 September 8, 2009 PDT
Researchers at the University of Washington (UW) have taken the term ‘green power’ literally by running an electric circuit from the power generated by trees. Sure, there isn’t much electrical power to harness, but the researchers say it should be enough to run wireless sensors that could be used to detect environmental conditions or forest fires and could also be used to gauge a tree’s health.

New Sony rechargeable battery charges faster and lasts longer
By Darren Quick
01:51 August 12, 2009 PDT
We cover our fair share of battery technology breakthroughs here at Gizmag, from lithium-sulfur batteries to NanoEnergy batteries. But it’s less often that we get to report on new and improved batteries actually hitting the market. So it was nice to learn that Sony has launched a new type of rechargeable Li-ion battery that promises an extended life span more than four times that of existing Li-ion batteries and can be charged to 99 percent of its full capacity in 30 minutes - approximately half the charge time of Sony’s current Li-ion battery line up.

Canadian startup proposes nuclear fusion power plant at a bargain price
By Darren Quick
00:40 August 4, 2009 PDT
Nuclear fusion offers a completely clean method of producing vast amounts of energy. So far the major stumbling block for scientists has been creating a controllable fusion reaction that achieves “net gain”, meaning it gives off more energy than is needed to trigger it. But Canadian startup, General Fusion, is claiming it can build a relatively low-tech prototype nuclear fusion power plant within the next decade for less than a billion dollars. Read More
Nissan’s 2010 EV in detail
By Jeff Salton
07:34 July 29, 2009 PDT
Nissan has showcased its electric vehicle (EV) platform on a Tiida-based hatchback model. The Nissan EV-11 prototype seats four-five adults, has a top speed of around 87mph (140kmh), a cruising range of 100 miles (160km) between charges and, being a full EV, produces zero local CO2 emissions. The in-house developed electric motor delivers 80kW (107hp) for “high response and powerful acceleration”. Nissan has also plans some clever IT for its EV platform, like remote ON/OFF charging via a cell phone or the Internet, useful mapping features including automatic updates on the nearest charging stations, a global data center providing 24/7 support and a scheme that could even see non-contact charging introduced in carparks.
