Biomechanical Energy Harvester Converts Human Motion Into Electricity

September 4, 2008 7:22 am | by Jason Lomberg, Technical Editor | Blogs | Comments

The inherent weakness of any portable device is its isolation from a constant power source, such as electricity. Thus, battery technology has evolved alongside the iPod and laptop computer. But batteries themselves are inefficient, because they either deplete themselves, or in the case of rechargeables, require electricity supplied from a power grid. But what if you could harness the energy produced by the natural motion of the human body? Bionic Power is endeavoring to accomplish that with its “Biomechanical Energy Harvester.”

The Mathworks Kicks Off EcoCAR Competition

August 25, 2008 9:19 am | by Jason Lomberg, Technical Editor | Blogs | Comments

On August 14th, 2008, The Mathworks held the kick-off to “EcoCAR,” a collegiate advanced technology vehicle competition (ATVC). EcoCAR’s subtitle (“The NeXt Challenge”) says it all- this is the spiritual successor to “Challenge X,” a similarly-themed ATVC contest that, last year, ended with Mississippi State University taking home the gold. In speaking with personnel from the DOE, The Mathworks, and GM (all event sponsors), I concluded that the biggest obstacle to ATV’s greater viability is a lack of young, qualified engineers.

“Green” Project Aspires to Reduce IT's Carbon Footprint

August 7, 2008 11:42 am | by Jason Lomberg, Technical Editor | Blogs | Comments

According to Doug Ramsey of UC San Diego, “The information technology industry consumes as much energy and has roughly the same ‘carbon footprint’ as the airline industry.” This is because of the unparalleled growth in high-speed electronic equipment, and the corresponding electricity requirements. Not only is energy necessary for the systems themselves, but as IT equipment blossoms, so does their cooling requirements.  It’s an implacable scenario that currently plagues the IT industry. Similar to hipster environmentalist celebrities who globe-trot on private jets, how do you conduct scientific research into efficiency issues when your investigative process gobbles up energy?


Energizer Stays One Step Ahead by Catering to Diminutive Device Trend

July 31, 2008 9:55 am | by by Jason Lomberg, Technical Editor | Blogs | Comments

“Quad A” may soon become part of the common vernacular. Although the AAAA battery (or Quad A) has been commercially available since 1989, it’s mostly been a niche product, difficult to find on shelves. But with consumer electronics moving towards smaller, more lightweight devices, with decreasing power requirements, the battery industry is adapting. Quad A has long been an internal industry standard for 9 V batteries (6 Quad A’s linked together, each generating 1.5 V, equals 9 V), but it could soon displace the AAA as the battery of choice for portable electronics.

EPA Creates Bedlam With Amendment for Residential Light Fixtures

July 22, 2008 5:17 am | by Jason Lomberg, Technical Editor | Blogs | Comments

Ayn Rand, one of capitalism’s greatest proponents, once said, “I am an innovator. This is a term of distinction, a term of honor, rather than something to hide or apologize for. Anyone who has new or valuable ideas to offer stands outside the intellectual status quo.” Governmental interference in private enterprise is always disastrous. What’s worse is when innovation is stifled by bureaucratic finagling and pc notions of impartiality (or as some would say, preventing a “competitive disadvantage”). You can’t give a chimp a skateboard and call him Tony Hawk.

Report Suggests Plug-in Hybrids Threaten to Strain Freshwater Resources

July 9, 2008 10:47 am | by Jason Lomberg, Technical Editor | Blogs | Comments

Advanced technology vehicles are the wave of the future, but they aren’t the elegant solutions advocates posit them as. The conservation of one resource inevitably comes at the expense of another resource. A report by Carey W. King and Michael E. Webber of the University of Texas suggests that plug-in hybrid electric vehicles (PHEVs) will place a strain on the nation’s freshwater resources. The research compares miles driven with a conventional internal combustion engine vs. a PHEV.

New Study Calls for World-Wide Reduction in Energy Consumption

July 3, 2008 8:42 am | by Jason Lomberg | Blogs | Comments

A Swiss Academic Study, “The 2000 Watt Society,” is gaining a lot of traction in the environmental movement.  First developed by researchers at the Swiss Federal Institute of Technology, the latest treatise ("Smarter Living") was coordinated by Novatlantis, and is an urgent call to action.  In short, it proposes an overall reduction in energy consumption to the world-wide average of 2,000 watts per capita by the year 2050.  Naturally, the US bears the brunt of the scorn.

Innovative Technology to Maximize Output of Solar Panels

July 1, 2008 6:14 am | by Jason Lomberg | Blogs | Comments

In 1839, French physicist Alexandre Edmond Becquerel discovered the “photovoltaic” effect, or the natural phenomenon which allows the conversion of solar into electrical energy. Over the next 150 years, this inexorably led to solar-powered satellites, solar cars, and solar-panel technology for domestic use. Among their many strengths, financial savings (after the initial investment), environmental conservation, and minimal upkeep, solar panels always suffered weaknesses inherent in a technology that relies on a giant ball of ionized gas 150 million kilometers away.


Nextreme Strives to Increase Efficiency of Heat-to-Power Conversion

June 30, 2008 10:47 am | Blogs | Comments

With soaring energy costs, all sectors are feeling the crunch, including the thermoelectrics industry. But Nextreme Thermal Solutions has a plan to stem the tide. One potential solution is to convert a system’s thermal energy byproduct into a functional resource. Using a grant from the North Carolina Green Business Fund, Nextreme plans to optimize their thin-film growth process with the goal of doubling the power output of a single device from 250mW to 500mW.

Chip Uses Novel Sleep Mode to Set Low-Power Record

June 24, 2008 4:23 am | Product Releases | Comments

A low-power microchip developed at the University of Michigan uses 30,000 times less power in sleep mode and 10 times less in active mode than comparable chips now on the market.The Phoenix Processor, which sets a low-power record, is intended for use in cutting-edge sensor-based devices such as medical implants, environment monitors or surveillance equipment. The chip consumes just 30 picowatts during sleep mode.

“Challenge X” Vehicles Strut Their Stuff In Manhattan

May 19, 2008 6:56 am | by Alix Paultre | Blogs | Comments

It may have been a cold and damp morning in Manhattan, but that didn’t damp the passions of the participants in the Challenge X national collegiate engineering competition. This year’s challenge, sponsored by the US Department of Energy and General Motors, focuses on technology integration and full-vehicle development of advanced alternate-technology drivetrain and subsystems. By participating in the Challenge X program, the students gain real-world engineering skills and hands-on learning to better prepare them for a future career in engineering.

Printed Flexible Solar Cells Provide Embedded Renewable Power

May 12, 2008 6:43 am | Blogs | Comments

With the cost of energy approaching the insane, new and improved methods of creating better and more easily deployable solar power cells are very welcome. This advance in manufacture by Konarka Technologies promises to deliver cheaper power cells in large quantities. I hope they can commercialize the technology to the point we can use solar as a tricke-charge backup in every powered application exposed to the sun.
