Garden hoses are the devil. They lay there, quietly baking in the hot summer sun, just waiting for some dumb schmuck to come along and try to take a sip—then BAM! A faceful of scalding hot water. More »

It’s estimated that in the US alone there’s over 140,000 miles of train tracks criss-crossing the country. So a team of researchers from New York’s Stony Brook University have developed a simple railside generator that’s able to convert the vibrations from a passing train into usable electricity. More »

Scientists use nanotechnology to harvest electricity from temperature fluctuations
Posted in: Today's Chili 
So far your footsteps, breath and nervous energy have all been tapped to charge up batteries, and now researchers from the Georgia Institute of Technology scientists have pulled it off using thermal changes. They did it with so-called pyroelectric nanogenerators, which use polarization changes to harvest heat energy from temperature fluctuations. Normally output current is too low for commercial electronics, but by making one with lead zirconate titanate (PZT), the team was able to create a device that could charge a Li-ion coin battery to power a green LED for a few seconds. The researchers predict that by doubling the surface area, they could drive wireless sensors or LCDs using only environmental temperature changes from an engine or water pipe, for instance. The result could be green power, but without all that pesky moving around.

The first commercial offshore wind turbine that Siemens created 30 years ago had 5-meter long blades and produced a paltry 30kW. A lot can change over three decades. The company’s newest offshore model isn’t just the biggest in the sea; it’s the biggest anywhere. More »

Homeowners in northern states have already had to turn on their furnaces and boilers this fall. And a lot of them are already paying too much to make the house warm and keep the lights on. The thing is, you don’t have to be a glutton to waste energy—many homeowners with good intentions still end up blowing money this time of year. More »

Urine-powered generator produces six hours of electricity per bathroom break
Posted in: Today's Chili 
We’ve all heard the expression “haste makes waste,” but how about waste making energy? At the fourth annual Maker Faire Africa in Lagos, Nigeria, a quartet of teenage girls ages 14 through 15 have created a urine-powered generator. This eco-friendly energy source cranks out six hours of electricity for every liter of human bodily fluid by separating the excretion’s hydrogen with an electrolytic cell. While this method of human waste disposal seems promising, the device has the potential to be a pee-powered biobomb and will need more than its limited safety measures before you’re able to pick one up at your local hardware store. However, if this can help us save a few bucks on our energy bill, then we need to introduce these girls to these guys posthaste.

IBM announces Smarter Energy Research Institute, aims to improve energy grids (video)
Posted in: Today's Chili 
IBM is no stranger to energy concerns, and now its founded the Smarter Energy Research Institute in partnership with Canada’s Hydro-Québec, the Netherlands’ Alliander, and the US’ DTE Energy to help build a better grid. The partnership will leverage Big Blue’s computing and analytic oomph to help the utility companies predict and detect anomalies within infrastructure, identify areas of the grid that need to be developed, integrate new energy sources and increase efficiency among other improvements. What’s this mean for you? For one, power outages should be less frequent and shorter lived when they do occur. Thanks to the distributed nature of the project, research will be spread throughout IBM’s worldwide network of research labs. If you’d like to hear more details straight from the folks involved, hit the jump for a video and the full press release.

Kaspersky Labs preps its own OS to guard vital industry against cyberwarfare
Posted in: Today's Chili 
Kaspersky Labs’ namesake Eugene Kaspersky is worried that widely distributed and potentially state-sponsored malware like Flame and Stuxnet pose dire threats to often lightly protected infrastructure like communication and power plants — whatever your nationality, it’s clearly bad for the civilian population of a given country to suffer even collateral damage from cyberattacks. To minimize future chaos and literally keep the trains running, Kaspersky and his company are expanding their ambitions beyond mere antivirus software to build their own, extra-secure operating system just for large-scale industry. The platform depends on a custom, minimalist core that refuses to run any software that isn’t baked in and has no code outside of its main purposes: there’ll be no water supply shutdowns after the night watch plays Solitaire from an infected drive. Any information shared from one of these systems should be completely trustworthy, Kaspersky says. He doesn’t have details as to when the OS will reach behind-the-scenes hardware, but he stresses that this is definitely not an open-source project: some parts of the OS will always remain confidential to keep ne’er-do-well terrorists (and governments) from undermining the technology we often take for granted.

As gadgets become more and more compact and portable, one thing that continues to stand in the way is the limitation of current battery technology. Just think of how the majority of space and weight inside your tablet or smartphone is its battery pack, and they still often run out of juice before you’re done for the day. As companies continue to work on improving battery life, and decreasing consumption, it would be nice to be able to generate more power when you need it. One conceptual device hopes to help a little bit, by harnessing the energy you expend when you walk or run.
While industrial designer Toby Blake’s Kinetic Charger concept isn’t the first such gadget, it’s definitely one of the more stylish and compact attempts to create a kinetic-energy storage device. The small USB charger would simply clip onto your beltline or a pocket, and would harvest energy you expend as you move around throughout the day, using reverse electrowetting technology.
Blake envisions that each one could store up to 4 watts of power, and you could connect multiples together to increase available energy levels.
Now there are probably some practical challenges that would limit the effectiveness of such as small kinetic-capture device, and there’s really not much room inside of it for a supplemental battery pack to store that energy in either. Still, it’s a cool design, and I’d love to see it come to market someday.
