Notre Dame heralds paint-on solar cells, wants to smear your home with its goop (video)
Leave it to the Fighting Irish to take a stab at solving the world's energy woes. Notre Dame researchers have successfully developed solar cells that can be easily painted on to any conductive surface. Imagine, for a moment, applying this solution to your home rather than attaching solar panels to the roof. The paint mixture incorporates quantum dots of titanium dioxide, which is then coated with either cadmium sulfide or cadmium selenide, and is then suspended in mixture of water and alcohol to create a spreadable compound that's capable of generating electricity. While its efficiency isn't currently much to crow home about -- which hovers around one-percent -- scientists are now actively pursuing ways to improve this aspect while making a more stable compound. Most importantly, the paint can be made cheaply and in large quantities, which suggests that even if efficiency remains in the doldrums, it may be a very worthwhile pursuit. Touchdown Jesus is already watching the video after the break.
Google's letting it shine as it nears $1 billion investment in solar energy
Google's feeling charitable this holiday and has pumped $94 million into a Californian solar-energy project. The photovoltaic power plant (which is a posh way of saying "lots of solar panels in the Sacramento desert valley") currently being built by Recurrent Energy will generate 88MW, enough juice for 13,000 homes. Additional investment is coming from equity fund KKR, who has already sold the first 20 years of energy to the Sacramento Municipal Utility District. It brings the search giant's investment in clean energy projects to $915 million -- with the company expected to cross the billion dollar mark some time next year, when we hope it'll get a nice loyalty bonus from Mother Nature.
Apple solar patent wants a sunny display light for your Sunny (De)light
Let's begin with the usual disclaimer: Apple patent applications do not mean the outlandish technology will be arriving in the next iPhone, just that someone in a Cupertino basement cooked it up during a marathon "imagining" session (possibly while enjoying a cool glass of purple stuff). The company's latest drawings-and-charts masterpiece concerns the construction and placement of photovoltaic cells and, more importantly, using the sun's energy to illuminate a display. By using a mirror pointed at the sky, you could reflect some rays toward your screen to supplement an LED backlight, or by turning the top lid of your Macbook into a solar panel. Although we can see one minor drawback in using solar powered backlighting -- if you have to point your display toward the sun, you're gonna need some powerful shades.
MIT researchers revolutionize solar cell printing, fold the power of the sun into your everyday home (video)
Wouldn't it be neat if you could power a few gadgets around the house with some tastefully chosen, solar cell-embedded curtains? Alright, so this MIT-pioneered tech's not quite that advanced yet, but it's destined to have a Martha Stewart Living future. By eschewing liquids and high temperatures for gentler vapors kept below 120 degrees Celsius, researchers were able to cheaply print an array of photovoltaic cells on "ordinary untreated paper, cloth or plastic." And here's some additional food for thought -- the vapor-deposition process used to create these cells is the same as the one that puts that "silvery lining in your bag of potato chips" -- science, it's everywhere. Despite the tech's home furnishing friendly approach, this breakthrough printing technique can't be done with your everyday inkjet, but it will make the cost of solar energy installations a bit cozier. Its flexible durability aside, the cells currently operate at only one percent efficiency -- so you might want to buy those drapes in bulk to see a real bottom line kickback. Foldable paper video demonstration after the break.
NTT DoCoMo to power cellphone towers with renewable energy, tenderness
When they're not busy carving handsets out of teak (or rockin' out with their pupils), the folks over at NTT DoCoMo apparently focus their efforts on saving the environment. Next year, the Japanese provider will begin outfitting its expansive cellphone tower network with ten "green transmission stations," to be powered by an artillery of biofuels, wind and solar energy. This kind of infrastructure would obviously bring a smile to the face of ol' Mama Nature, but it could also help mitigate the adverse effects of power outages and elfin insurgents. And for that, we should all be grateful.
Quantum dots could coat the world in nano-sized solar panels
We've long believed in the mystical power of quantum dots, so it makes perfect sense to us that one day they'll be used to fully harness the Sun God's rays and thereby save the planet. The nano-particles turn light into electricity, and could potentially be manufactured cheaply and abundantly enough to coat surfaces in current-generating paint. The main obstacle to this has so far been efficiency: the clever little dots just don't work very hard. However, scientists at the University of Toronto now claim to have discovered a fix. Instead of using a single layer of particles, which can only harvest one meager wavelength from the full gamut of solar light, they added a second coat on top and configured it to be sensitive to an additional part of the spectrum. By adding third and fourth layers, the researchers hope to achieve a commercially viable efficiency of 10-percent within the next five years. We humbly call on Ra to be pleased with their efforts.
Solar Cross e-bike soaks in the sun, powers your pedals
Ah, the bicycle -- that first symbol of locomotive independence from our youth. How we've often wished you came with a motor, solar power and some rechargeable batteries to make that ride less... taxing. Well, chin-up childhood glory days, because Terry Hope's done all that and a bit more. The self-described EV enthusiast outfitted a Specialized FSR bike frame -- chosen for its double crown suspension fork -- with an array of three solar slats, a 24-volt one horsepower motor, and three 5,000mAh Li-ion batteries to assist your pedaling on those grueling uphill climbs. The sun-soaked panels powering this 18-speeder's motor are a homemade mix of polycarbonate sheeting, aluminum and 18- x 6- x 6- inch mono crystalline cells that generate a combined 8.7-volt charge to the batteries of your choosing. While its beneficial turbo boost isn't intended to replace that Harley you've got covered in the garage, it will takeover on those lazy days when you just feel like cruising. Hilarious robot voice over for the environmentally-conscious cyclist after the break.
Inhabitat's Week in Green: 'round the clock solar plants, USB camping pot and wave energy farms
Green transportation soared to new heights this week as Inhabitat showcased the world's first true hybrid-electric airplane, and we spotted plans for a zero-emission hypersonic jet capable of traveling from London to New York in a single hour. Meanwhile, Japan gave the green for the construction of a blazing fast 313 MPH maglev train line, and we spotted a crazy high-speed rail concept that would allow passengers to change trains while speeding along the tracks. We also watched as an 11-year-old student piloted a 1,325 MPG hypermiling supercar and we saw an 8-ton Volkswagen beetle sculpture sink into the sea to start a new life as an artificial reef. It's been a scorching summer for solar power as Torresol opened the world's first 24/7 solar plant in Spain, and Samsung unveiled the first photovoltaic-laden laptop to be sold in the US. We also saw Aquamarine Power break ground on a massive wave energy farm in Orkney, while Germany hatched a plan to store excess wind power in abandoned coal mines. Finally, we spotted several novel incredibly odd new energy-generating gizmos -- a t-shirt that converts rock music into electricity and a power-generating USB camping pot that charges your gadgets as you cook. Speaking of renewable energy, this week we caught a first look at the amazing EDV-01 shelter -- a high-tech solar-powered building with a luminous LED facade that is capable of doubling its capacity with the flick of a switch. We also brought you Adrian Smith and Gordon Gill's plans for the world's 4th tallest skyscraper, and we showcased an ultramodern paperless office in the Netherlands that looks like a meteor fallen from space. Last but not least, we took an exclusive first look inside BIG's mountainous green-roofed eco village in Copenhagen, and tech expert Peter Rojas tackled the question of whether it's better to turn your laptop off or set it to sleep in our Ask a Tech Geek column.
Google's search for future profit targets the Sun, not just the cloud
These humble-looking contraptions were revealed in a Google patent application for a "heliostat control system" that automatically adjusts solar thermal mirrors to their optimal energy-harvesting angle. A camera and computer are housed in the central tower that receives heat from the mirrors, and together they detect when a heliostat is misaligned and then correct it using actuators. Sound like a strange distraction for an Internet company? Google thinks not. It's already invested $168 million in the world's largest solar tower in the Mojave Desert as part of its effort to both reduce its own massive electricity bill and diversify its business. It's also currently hiring three new technical staff to make this happen. Interested?
Solar Impulse completes first solar-powered international flight, Captain Piccard returns to earth
We're big fans of charming, ungainly Solar Impulse, and of Captain Bertrand Piccard and Andre Borschberg's quest to circumnavigate the globe in a solar-powered plane. In case you missed the live stream: the Swiss flier just got a little closer to that goal by completing its first international flight, taking off near Berne, Switzerland and landing in Brussels, Belgium, just under 13 hours later. That's half the flight time of an earlier test, in which the craft's 200-foot wingspan, covered with 12,000 photovoltaic solar cells, kept it aloft for 26 hours. Of course, a controlled test flight is one thing -- making solar-powered flight commercially viable means proving your plane can successfully navigate busy airspace. To see Solar Impulse come in for a smooth landing, peep the video after the break.
B-Squares bring portable solar energy and Arduino compatibility to toy blocks (video)
We've seen plenty of portable solar chargers in our time, but few have looked quite as versatile as B-Squares -- a new collection of 3D modular energy storage devices that can be arranged in various configurations, according to the kind of gadget you're looking to juice. Developed by MIT grads Jordan McRae and Shawn Frayne, each solar-powered B-Square features a sticky microsuction surface, along with magnetic and electric contacts at each corner, making it easy to connect and arrange them in different formations. Rotating a single square will change its electrical circuit, depending on its adjacent connection. Some B-Squares, for example, feature LED surfaces, allowing you to create solar-powered lanterns, while others have solar panels, or simply serve as rechargeable battery sources. There's even a square devoted to Arduino boards, along with another surface designed to dock and charge iPhones. McRae and Frayne have already put together a full "recipe book" of different configurations, though the DIY route seems a lot more enticing to us. Their B-Squares are set to leave the prototype phase on May 1st, at an as yet unspecified price. Check them out in video action after the break. [Thanks, Ryan]
Sharp's Intelligent Power Conditioner works with EVs to make your house a lean, mean, solar-powered machine
So, you've got your government-issued solar panels and you bought a plug-in EV, but being both a budget-minded and green-conscious geek, you're concerned that your home's power generation and consumption isn't exactly optimal. Put your worries aside, because Sharp has created the Intelligent Power Conditioner (IPC) to max out the electrical efficiency of your abode while working in conjunction with public utilities. It operates by temporarily storing the unused solar-generated juice from the daytime -- using both the system's batteries and the cells in your shiny new EV -- to deliver a steady stream of electrons at night. In tests with a Mitsubishi i-MiEV, the system was able to use the EV to supply 8kW of power to a home, and doled out enough electricity (4kWh) to recharge the car in a scant 30 minutes. The IPC is still in the development phase, but Sharp is looking to make it commercially available "in the near future" -- which means the finishing touches on your ultimate eco-house will have to wait.
UM students make cheap and portable solar charger / light source for developing nations
Solar power is the most egalitarian of all energy sources, yet residents in many parts of the world still lack access to electricity. Three University of Michigan engineering students have created an affordable solution to this problem -- to the delight of camping geeks everywhere -- with the Emerald, a portable solar panel that does double duty as both a cellphone charger and personal light source. We've seen the personal solar panel idea before, but the price of entry made it an untenable solution for developing nations. Solar-powered light bulbs have been around for a while too, but the Emerald's light lasts for eight hours on a charge (as opposed to the bulbs' two to six hours), and it's able to fully charge a phone in the same time it takes an outlet to do the job. They aim to sell the device for the low, low, price of under twenty bucks for customers in the developing world, which is 90 percent cheaper than other solutions and 100 percent more awesome.
Zephyr solar-powered UAV breaks three more world records
The Zephyr is a winning machine. Last we reported, QinetiQ's solar-powered drone had just completed 7-days in the air, and counting. Now, the Federation Aeronautique Internationale (FAI) has confirmed that Zephyr completed that record-breaking flight with a solid 2-weeks in the air (336 hours). If that wasn't enough to put other drones to shame, FAI found that Zephyr also destroyed records for flight duration for a UAV of its class, and the altitude record for that class at 21,562 meters, or 70,741 feet. So keep the records coming, Zephyr, because everyone loves a winner, even when that winner is a unmanned war machine.
Philadelphia Eagles going self-sufficient on stadium energy from 2011, 30 percent of it renewable
Let's skip right past the cringe-worthy "Declaration of Energy Independence" slogan and look at what the Eagles are actually doing with their pro sports venue. The franchise that dresses in midnight green is aiming to smarten up its eco-green credentials with a new partnership with SolarBlue that will provide all of the Eagles' stadium energy needs for the next 20 years, after which point the team will be free to resell any surplus electricity back to the grid. 15 percent of the total output with be generated with spiral wind turbines erected around the top rim of Lincoln Financial Field, another 15 will come from 2,500 solar panels to be installed near the stadium, and the rest will be obtained from a biodiesel / natural gas plant. So it's not all renewable, but a nice step in the right direction, nonetheless.
Puma Phone review
So it's true, we're living in an age where people would shamelessly line up for certain electronics and luxurious fashion items. Why? Just because they can, and for that reason, some swanky outlets -- namely Christian Dior, Prada, Giorgio Armani, Dolce & Gabbana, and Versace -- have attempted to exploit our gadget lust by offering self-branded phones at extortionate prices. In the eyes of every-day consumers, there's really not much appeal in these soulless devices except for the logo and some extra bling, but apparently these two factors alone are enough to make some aficionados drool a river. On the other hand, Puma -- a less luxurious but naturally more accessible fashion brand -- has decided to do more than just slapping an OS skin onto its aptly-named Puma Phone. Priced at a comparably affordable £300 ($469), this Sagem-made featurephone packs a few unusual features such as a solar panel, a sports tracker, and even a virtual cougar named Dylan. Read on to find out if we could sense the Puma spirit in this device.%Gallery-99609%
Duke study finds solar power cheaper than nuclear, Coach K stronger than Roy
Now, before you get all hot and bothered here, we should warn you that this study only uses information from within the great state of North Carolina (where Duke University is based, obviously), but the results are intriguing regardless. According to new data, the moment we're living in is a crossover one where the declining prices of solar panels may actually make sun-based energy more cost efficient to consider than nuclear. Duke found that the crossover price point was at around 16 cents per kilowatt hour (kWh), and for the first time ever in NC, the cost of one kWh of electricity from solar energy sunk below that. Of course, these results are apt to be even more impressive in sun-rich states like Arizona, Nevada and Utah, but it's fairly clear what the real purpose of the investigation was: convincing the school to shell out for solar panels to energize Krzyzewskiville during week-long campouts for UNC vs. Duke tickets.
IKAROS gets first burst of solar propulsion, wants more
Photons, man, it's all about the photons. Japan's solar sail-equipped IKAROS probe has recorded its first propulsion derived from the force of sunlight rays hitting its tender surface. The force generated is a truly minuscule 1.12 millinewtons, but that can go a long way (literally) in a frictionless environment like space. The kite's sails also soak up Sol's emitted light to generate electricity, making the most out of the one resource available to it. So now that we've figured out how to do all that, shall we get started on colonizing Mars or what?
Solar Impulse returns from 24 hour test flight 26 hours later
Rest easy, fans of solar-powered aeronautics. Captain Piccard's Solar Impulse has safely returned after 26 hours in the air -- powered by nothing but the sun. The four-engine aircraft, which features 12,000 solar cells arranged on its wingspan, reached a height of almost 29,000 feet before touching down at Payerne Airport near Berne, Switzerland today. The next step? The team is going back to the woodshed, with the hope of developing a plane that will circumnavigate the globe by 2013.
Solar Impulse begins 24-hour test flight, lets you watch the whole thing live
Boy, these Franco-Swiss research teams sure do like to exhibit their work to the world. After the Large Hadron Collider crew did a live webcast of their record-breaking 7 TeV proton collisions, here's Captain Piccard's Solar Impulse gang showing off their latest feat via a live video stream. Taking off shortly before 7AM Central European Time today, the HB-SIA craft is currently cruising above the idyllic plains of Switzerland, with the plan being for it to start gently descending through the night and plopping itself back down on terra firma early in the morning. Hit the source link to track its laps in real time, replete with sporadic commentary from the monitoring crew. It's riveting stuff.
