Ferroelectric material could make your smartwatch run longer
Elon Musk's big plan involves charging your electric car with shingles that are solar panels. While that's incredibly impressive -- not to mention ambitious -- it uses only one form of alternative energy. Finnish scientists have a different idea: harnessing heat, kinetic energy and sunlight simultaneously to help power your gadgets. This involves using a ferroelectric material (think: the stuff inside ultrasound machines or fuel injectors for diesel engines), KBNNO, to generate electricity from heat and pressure. That's according to a post on Phys.org.
Elon Musk to show SolarCity rooftop panels October 28th
We knew that Elon Musk was working on a roof made of solar panels, and now we know when we'll see them: October 28th, according to a tweet from the real life Tony Stark. Assuming San Francisco's trademark fog doesn't make a surprise appearance too, that is. He says that the SolarCity demo will take place in the Bay area and that we'll also see how the tech integrates with his other projects, the Powerwall 2.0 in-home battery and a Tesla charging system. I'm sensing a theme here...
Urine-powered generator produces six hours of electricity per bathroom break
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.
Greenpeace boosts Apple's rating, but barely
Greenpeace recently released an environmental report on Apple and upgraded the company's score from an F to a D, says a report in Wired. Greenpeace pointed to Apple's commitment to use alternative power at its North Carolina and Oregon data centers as the reason for this small boost in score, but wanted additional details on how the Cupertino company was going to carry out its plans. Apple has said publicly that it expects to power 60 percent of its North Carolina data center and 100 percent of its Newark, California center with renewable energy. Its upcoming Oregon data center will be power by a combination of hydro, geothermal and wind energy. The environmental watchdog also listed several recommended steps Apple should take if it's serious about the environment. These steps include choosing a renewable-powered utility for its Oregon Data center and seeking alternatives to using the "dirty electricity" from Duke Energy. Instead of relying on coal-based power, Greenpeace encouraged Apple to "use its buying leverage with Duke Energy and other utilities to push for cleaner electricity options."
Study says wind turbines raise surrounding area temperature, but only at night
Who said the butterfly effect couldn't apply to renewable energy? Though wind farms are considered pretty green on the energy-generating spectrum, it looks like they, too, have an impact on the planet. According to a study published today in the journal Nature Climate Change, turbines can raise the local temperature -- albeit slightly. From 2003 to 2011, researchers monitored satellite data for west-central Texas, which is home to 2,350-plus turbines and four of the world's largest wind farms. In that decade, scientists observed a temperature increase of 0.72 degrees in wind farm regions compared to areas without turbines. That warming trend was especially marked at night, when the temperature difference between the ground and the air is highest. The temperature increase was also higher in winter; researchers say that these cooler, windier conditions cause turbines to generate more electricity and therefore create more heat. Since the study didn't find any change in daytime temperatures, it looks like we don't have to ring the global warming alarm just yet.

Has James Bond gone green? Bulletproof electric roadster in the works
Warding off assassins while saving the environment just became a cake walk with the Jo-Mojo, an upcoming creation by Lativian armored vehicle company DARTZ. This two seat convertible roadster brandishes an 80 horsepower electric engine capable of pushing zero to 60 mph in 9.5 seconds and a top speed of 125 mph -- yet most of its "mojo" is outside the hood. Custom seating, color-changing chameleon paint finish, bulletproof tires, and others are just a few of the many "drooling" features. The sunroof is given a task with flexible solar panels built-in, good for juicing up the batteries while idle or on the go. Aimed to hit the market at the end of Q2 2012, its estimated price tag starts at 30,000 euros (~ $40,000), within range of most low-end luxury automobiles. Check past the break for a video slideshow of this snazzy piece of metal by Gray Designs, DARTZ's partner in the venture.
Aptera fresh out of greenbacks, closes up shop
Bummer for fans of teardrop shaped three-wheelers, as your favorite chariot, Aptera's 2e, will never see the light of day. Despite getting the ball rolling on a $150 million loan from the DOE, subsequent funding and time just weren't on the startup's side. An unfortunate prognosis, as CEO Paul Wilbur revealed the company had been working on a $30,000 mid-sized sedan that would have touted 190 miles of electrical range. He's still adamant the company had "never been closer" to realizing its vision, but hopes someone else can carry on Aptera's torch. Those nuggets and more await in what is possibly the company's final tell-all after the break.
Navy blends Jet A and algae-based biofuel, uses it to power Seahawk chopper (video)
Considering that helicopters are entirely dependent on a spinning rotor to remain in the air, an MH-60S Seahawk doesn't exactly seem the most likely candidate for experimental fuel. That didn't seem to stop the US Navy, however, which successfully completed a test flight with a 50 / 50 blend of algae-based biofuel and Jet A (traditionally the flavor of choice for turbine-based aircraft). The mixture used is known as Solajet HRJ-5 Jet fuel, which doesn't quite have the same ring to it as good ole Jet A -- but it does happen to be based on a renewable resource and managed to keep the rotor spinning. There's no word on how much the new fuel costs to produce or when it might be ready for commercial use, but if all goes to plan, we may soon be using the green stuff for more than just sushi rolls and miso soup.
Thin film coating makes everlasting energy a piezoelectric possibility
Let's be honest, it's no big secret that we're running out of dead dinosaurs to fuel our lives. And with recent natural catastrophes proving atomic energy isn't what you'd call 'safe,' it's a good thing the researchers down at the RMIT University in Melbourne have been hard at work figuring out how to turn you into a self-sustained energy source. Marrying piezoelectrics with a thin film microchip coating, those scientists Down Under have for the first time identified just how much energy your pressure can generate. This is certainly not the first time the tech has been put to use -- Orange UK's been doing something similar, albeit bulkier, for the Glastonbury fest each year. What are some practical uses, you ask? Imagine a gym powered by a sea of workout-hamsters, each producing significant energy from the soles of their feet. Curious for more? Try a pacemaker that runs solely on blood pressure, or a laptop charged by banging out Facebook updates. Who knows, maybe even RIM can put this to use in its next Storm. Just sayin'.

eGenius electric plane takes flight with Airbus backing
It's been mere months since we introduced you to Deutschland's PC-Aero Elektra One, and now the Germans are at it again with the maiden flight of a new electric flying machine: eGenius. The aircraft successfully completed a 20-minute flight on May 26th, followed by a two-and-a-half hour trip on Sunday. Where the Elektra one boasted cruising speeds of 160 km/h (about 99 MPH), eGenius is capable of hitting 235 km/h (146 MPH) for up to 400 kilometers (248.5 miles). It sports a 60-kilowatt motor, weighs 850 kilograms (1,874 pounds), and has some big backing from the likes of Airbus. Considering its relatively limited range and equally limited capacity -- it fits two humans with a combined weight of 397 pounds -- we have a feeling it'll be a bit before we're popping pretzels on one of these bad boys.
Google backs Alta Wind Energy Center, boasts $400 million clean energy milestone
Google announced today that it's throwing $55 million dollars to the wind... energy, that is. A post to the official Google blog said the company has invested the aforementioned amount in the Alta Wind Energy Center, which is set to generate 1,550 megawatts of energy -- enough to reportedly power 450,000 homes -- from a batch of turbines in the Mojave Dessert. Developed by Terra-Gen Power, the operation will carry the resulting energy via transmission lines to "major population centers." The ever-humble internet giant pointed out that this particular injection of funds marks a total investment of $400 million in the clean energy sector. In fact, El Goog signed a deal last year to power several of its data centers with wind power, and most recently announced the opening of a seawater-cooled data center in Finland.
ORNL energy harvester turns heat waste into electricity, converts hot machines into cool customers
We've heard of turning yesterday's lunch into tomorrow's electricity, but a new energy converter coming out of Oak Ridge National Laboratory harnesses the power of a different type of hot waste. The as-of-yet unnamed thermal waste-heat converter has the potential to cool electronic devices, solar cells, and computers while generating electricity from excess heat. Its creators see the new conversion process being used to reduce the massive amounts of heat generated by petaflop computers. The converter employs up to one thousand tiny cantilevers attached to a one square inch surface (e.g. a computer chip) to produce between one and ten milliwatts of electricity -- admittedly a very small amount of energy. However, it's creators are quick to point out that a slew of these converters could generate enough power to perform small tasks in the heat-generating device -- things like sensing when a server room gets too hot for comfort. Sure it's a small step, but if they can get this stuff to save our future babies from cooking, we're all in. Full PR after the break.
Biodiesel can be harvested from leftover food, kids no longer have to clear their plates
The best dishes always contain 30 per cent fat minimum. This doesn't merely ensure a level of hearty satisfaction (Windows 7 Whopper anybody?), it also means the leftovers contain plenty of the greasy good stuff, which can be cleverly harvested and metamorphosed into biodiesel. The technology behind this process has been around for a while, but now British firm Greenergy claims it is ramping up commercial production. The firm's CEO reckons each of his new £50million ($80million) biodiesel plants will digest a sufficient volume of waste pies, fries and taramasalata to "fill out a cruise ship every year". Mmmm, pie.
Obama says federal fleet to run on alternative fuels starting in 2015
Chances are the Secret Service won't be ditching its signature black SUVs for these things anytime soon, but if all goes according to President Obama's new energy plan, even the Commander in Chief's armed guards will be rolling more eco-friendly in the next three years. In a speech given at Georgetown University Wednesday, the President said he expects all government agencies "to purchase 100 percent alternative fuel, hybrid, or electric vehicles by 2015." Now, that doesn't mean they'll have to get rid of pre-existing gas guzzlers, but any new purchases made after the cutoff date will be expected to comply -- the government's current fleet consists of 660,000 vehicles, 400,000 of which run on gasoline. Among other things, the President also called for increased infrastructure for the production of biofuels made from things like wood chips and switchgrass. So no, Cadillac One probably won't be replaced by a rechargeable egg car, but if Uncle Sam's taking suggestions, we'd be happy to make a recommendation -- Wheego Whip LiFe One does have a nice ring to it. Doesn't it?
MIT professor touts first 'practical' artificial leaf, signs deal with Tata to show up real plants
A professor at MIT claims to have Mother Nature beat at her own game. Dr. Daniel Nocera says his invention is ten times more efficient at photosynthesis than a real-life leaf, and could help to bring affordable alternative energy to developing countries. Described as an "advanced solar cell the size of a poker card," the device is made of silicon, electronics, and inexpensive catalysts made of nickel and cobalt. When placed in a gallon of water under direct sunlight, the catalysts break the H2O down into hydrogen and oxygen gases, which are then stored in a fuel cell -- the energy produced is apparently enough to power a single house for a day. Of course, this isn't the first time we've seen scientists try to one-up nature, in fact, we've seen solar-powered leaves before, but this thing actually looks poised for the mass market -- Nocera signed a deal with Tata in October. Full PR after the break.
H2O Shower Powered Radio blasts the Biebs by way of micro-turbine
Forget the tablet, 2011 is the year of the shower radio! Last week we reported on Toshiba's wirelessly connected water-proof song box and, just as our nerves began to settle from the excitement, someone came along and dropped this eco-friendly, shower-ready gem on us. Not only is the H2O Shower Powered Radio waterproof, but it actually uses the water from your shower to pump out the jams. The thing connects directly to your shower hose, and uses the flow of water to set a micro-turbine spinning, thus charging an integral battery and eliminating the need for disposables. As the video below points out, the radio "doesn't just offer 80s classics -- it has the full spectrum of FM," and its creators say it's compatible with 99 percent of showers, but what we really want to know is: how well does it crank the Ke$ha? Video after the break.
Self-repairing solar cells could also fix our energy dependency
It doesn't take much for a photovoltaic cell to not work quite as well as it used to. Sure, a big hail storm or the like will do a number on your megabucks rooftop installation, but the sun itself, the very thing those cells are designed to capture, gradually damages their internals, reducing efficiency. The fix, according to a team at MIT, is self-assembling (and therefore self-repairing) solar cells made up of a synthetic molecular soup containing phospholipids that, when mixed with a solution, attach themselves to a series of carbon nanotubes for alignment. Other molecules that react with light then attach to the phospholipids and, with a little illumination, start firing out electrons like mad. After a few hours of solar pummeling the whole thing can be broken down and automatically re-created, returning efficiency to maximum. Overall efficiency of the system is extremely low currently, thanks to a low concentration of those photon-catching structures, but individually they capture about 40 percent of the light's energy, meaning a higher concentration could make for very hearty soup indeed.
Airborne electricity is ripe for the picking, claim researchers
Electricity might not grow on trees, but it is freely available in the air -- provided you know how to catch it. Such is the contention presented by Dr. Francesco Galembeck of Brazil's University of Campinas at the 240th annual American Chemical Society shindig. He and his crew have shown how tiny particles of silica and aluminum phosphate become electrically charged when water vapor is passed over them. This aims to prove two things: firstly, that airborne water droplets do carry an electric charge, and secondly, that metals can be used to collect that charge. Detractors have pointed out that Dr. Galembeck's team may be generating the droplets' electrical charge by the act of pumping the air over the metals -- which might imply you couldn't practice this technique with still, humid air -- while there's also the rather large caveat that the little electricity they were able to collect from vapor was a hundred million times less than what you could obtain from a solar cell of equivalent size. Still, it's another new door unto a potential alternative energy source and we don't ever like having to close those.
Photon enhanced thermionic emission could double efficiency of solar cells
Engineers at Stanford have developed a process which can harness the light and heat of the sun simultaneously, which could lead to solar cells that are twice as efficient as those currently available. Called photon enhanced thermionic emission -- or PETE for short -- the process differs from traditional cells which lose efficiency as temperatures rise, and the materials needed to build the cells are cheap and widely available. The engineers got around the lower efficiencies by coating a piece of semiconducting material with a thin layer of the metal cesium, which enables the material to use both heat and light simultaneously. While the materials as currently demonstrated work best in very high temperatures, the researchers indicate that in the near future, the materials could have wide enough application to make them competitive with traditional forms of energy. Hit the source for the full story.
