    Remember that USS Enterprise-esque ocean research vessel we first ran across back in 2005? Yes, the one that was originally slated to hit the open waters in 2008 or 2009. After catching heat for its lofty ambitions for the last 12 years, the SeaOrbiter is finally set to begin construction later this year. The ship is slated to measure 170 feet (51 meters) tall, but to stabilize the vessel over half of the vehicle would stay below the surface, providing all sorts of collection systems and useful tools. Not only does it look like something out of Minority Report, but the SeaOrbiter is 100% sustainable. The ship's power is set to come from solar, wind and wave power with biofuel in case nature doesn't cooperate -- when the vessel isn't adrift via ocean currents. Funding has been obtained for the $52.7 million undertaking, which will produce an endless amount of data on global warming and marine biology around the globe. For a look at some renders of the massive vehicle, click though the gallery below for a quick peek. %Gallery-158595%

    Have you ever harbored delusions of living in an underwater city inhabited by the likes of Ariel or those aliens from The Abyss? Yeah, well keep dreaming, because this engineering feat won't necessarily lead to that (the fictional mer people part, that is). What it will pave the way for is a new means of harnessing the sun's rays below sea level to power submerged sensor systems and platforms. The research, carried out by a team of U.S. Naval scientists, forgoes traditional crystalline and amorphous silicon photovoltaic cells for those based on the more efficient gallium indium phosphide. The reason? Turns out those latter semiconductors are well-suited to absorbing photons in the blue / green spectrum -- precisely the wavelengths that diffused sunlight take on under water. Using this newer approach, the team's proven that about 7 watts of energy can be generated per square meter of these deployed cells at a depth of up to 9.1 meters (30 feet). Further refinements and testing are, naturally, on deck, but soon enough we may be looking at a whole new world of possibilities under the sea. [Image courtesy Flickr]

    The Impulse solar-powered plane has successfully completed its first transcontinental journey. It took 19 hours to jet between Madrid and Morocco -- with the plane's 12,000 solar cells swallowing enough power to keep it going long into the night. Pilots Bertrand Piccard and Andre Borschberg can now look forward to planning their next voyage: a round the world cruise penciled in for 2014.

  • Solid state solar panels are more affordable, say researchers, don't leak

    Researchers at Northwestern University have found one way to stop a leak: get rid of the liquid. A new variation on the Grätzel solar cell replaces a short-lived organic dye with a solid alternative. The molecular dye the solid substance replaces was corrosive, at risk of leaking and only lasted about 18-months -- by replacing it, researchers plan to pave the way for a more affordable (and less toxic) alternative. Northwestern's new design flaunts a 10.2-percent conversion efficiency, the highest ever recorded in a solid-state solar cell of its type -- but that's still only half of what traditional sun collectors can do. Researchers hope to improve conversion in the long run, but expect that the cost reduction alone will be enough to get the party going. It may not be the greenest solar technology we've ever seen, but who are we to judge?

    While initially announced in the summer of 2011, the Son-X Octavia has been working its way into reality ever since. As of this month, though, the solar-powered "interactive sound device" is now shipping to schools in Europe. For those unfamiliar, the coconut-esque device straps onto a conventional swing set in order to keep kids outside -- using technology to prevent kids from becoming supersaturated with technology, if you will. The company has designed it with tight school budgets in mind, making it completely wireless, self-contained and easy to install. Once in place, swingers can activate three aural games, each of which act to "awaken the natural curiosity in children to explore the possibilities through activity." Not surprisingly, it's designed to be upgraded over time, with new titles to be made available on USB drives. The outfit's still not offering 'em direct to consumers, but those with B2B connections can grab one for €499 ($624).

    The sun-powered Solar Impulse plane is gradually working up to a trip around the globe, with the most recent benchmark being its first international flight in 2011. Now Bertrand Piccard and Andre Borschberg are taking the jumbo jet-size plane on its first transcontinental journey. The Solar Impulse set off for Morocco today, and its pilots will stop in Madrid along the way. The goal is to complete the 1,554-mile trip by next week, and the big challenge will be crossing cloudy regions like the Pyrenees mountains separating France and Spain. In a 2010 test flight, the Impulse's 12,000 solar cells soaked up enough rays to keep the plane going through the night, but in case something goes wrong this time, the pilots are prepared with parachutes. If all goes well on this trial run, Piccard and Borschberg will be just one step away from their goal of circumnavigating the world in 2014.

    We're used to batteries powering a lot of devices, but the University of California, Riverside is upping that a notch by charging up a whole floor's worth. The school's Winston Chung Global Energy Center is walking the eco-friendly walk and has started using a huge bank of rare earth, lithium-ion batteries from Balqon to produce 1.1 megawatts, enough to keep Winston Chung Hall's entire first floor humming along while tapping renewable energy sources like solar and wind power. The batteries bank their energy overnight, keeping the throngs of students happy without having to recharge as much or use the regular power grid as a fallback. While it's considered a testbed, the university's giant battery is considered a blueprint for cellular towers and the green power sources themselves -- the combination of which could keep your smartphone up and running with a lot less of an environmental hit.

    If you'd been by the shore of the Sumida River in central Tokyo this past weekend, you would have noticed that it was glowing a distinct shade of blue. That's because Panasonic decided to kick off the first-ever Tokyo Hotaru (fireflies) festival by sending 100,000 EVERLED light bulbs down the river, both to mimic fireflies as well as to pay homage to a Japanese tradition of floating candles on the water. Before you cringe too much at the thought of the environmental impact, rest assured that Panasonic minimized the footprint of its aquatic LED parade. All the bulbs ran on solar power (presumably, charged during the day) that kept Evolta batteries fed inside, and the entire lot was scooped up in a large net afterwards. We love the exhibition as a large-scale demo of sustainable lighting -- you may just want to avoid fishing along the Sumida's shoreline for awhile in case you catch a straggler. Update: We've found a video of this spectacular event -- check it out right after the break.

    It's been two years since we last heard of the 98-foot-long solar-powered boat, which at the time was gearing up for its big journey around the world. Well, some 19 months and 37,286 miles after setting sail from Monaco, the MS Turanor PlanetSolar has finally made it home. The PlanetSolar broke four Guinness world records along the way, including the all-important "first circumnavigation by solar-powered boat," and it made stops on six continents to promote solar energy. Oh, and the team fended off Somalian pirates in the process, too. Now that it has a moment to catch its breath and soak up some rays at leisure, the MS Turanor could become any number of things -- from the world's largest solar battery to a "green luxury yacht." The latter option would certainly befit its chichi home port.

  • Logitech unveils its Solar Keyboard Folio for the new iPad and iPad 2, we go hands-on

    There are all sorts of ways to go green these days, from driving an EV to installing super efficient light bulbs, and now Logitech's given us an environmentally friendly way to type tactilely on a tablet. It's a new iPad and iPad 2-friendly case called the Solar Keyboard Folio, which packs a Bluetooth keyboard powered by ambient light using the same solar cell tech found on the firm's computer keyboards. Once topped up with photons, Logitech claims its battery will keep you typing for over 1,000 hours even in complete darkness. The case is crafted of black, soft-touch, faux leather embossed with a small Logitech logo and has perforations for the iPad's speakers, plus a portal for the tablet's camera. Its keyboard is made of gray plastic, and pecking at the grid is a similar experience to using the one found on Logitech's other recently released iPad typing peripheral, the Ultrathin Keyboard Cover. Buttons are short-throw and provide satisfying clicky feedback, but the space bar and shift keys have a hollow feel when pressed. Perhaps the Folio's most intriguing design feature is the feet on the corners of the cradle in which the iPad is placed. Those little nubs allow for two viewing angles -- your slate can be seated in a more upright position behind the keyboard for typing, or in the notches outside the two shift keys for a more obtuse viewing angle when the keyboard isn't needed. What's this bit of green gear cost? It goes on sale in the US and Europe this month with an MSRP of $130.

  • USC develops printable liquid solar cells for flexible, low-cost panels

    Solar cells are becoming more viable sources of energy -- and as they become more efficient, they're only getting smaller and cheaper to produce. Liquid nanocrystal cells are traditionally inefficient at converting sunlight into electricity, but by adding a synthetic ligand to help transmit currents, researchers at USC have improved their effectiveness. The advantage of these liquid solar cells? They're cheaper than single-crystal silicon wafer solutions, and they're also a shockingly minuscule four nanometers in size, meaning more than 250 billion could fit on the head of a pin. Moreover, they can be printed onto surfaces -- even plastic -- without melting. Ultimately, the goal of this research is to pave the way for ultra-flexible solar panels. However, the scientists are still experimenting with materials for constructing the nanocrystals, since the semiconductor cadmium selenide they've used thus far is too toxic for commercial use.

  • Spinach-based solar cells get $90,000 development funds from EPA, Popeye delighted

    A biohybrid solar panel that substitutes expensive silicon components for a spinach protein has been granted some substantial Phase II funding from the EPA. Students from the Vanderbilt School of Engineering managed to stand out from 44 other university teams vying for funding at the National Sustainable Design Expo held in Washington DC. The team's large-scale panel only ekes out a small amount of electricity from the photosynthetic proteins at the moment, but according to Professor Kane Jennings, the cash injection from the EPA will help achieve higher energy conversion ratios over the next few years. Perhaps you could try wrapping them up into giant 3D cubes, Professor. [Thanks Brandon]

    If you've ever dreamed of thumbing your nose at big energy and its expensive, polluting ways, then Tesla and a solar panel leasing company called SolarCity might be taking you a baby-step closer to reality. Although recognized mostly for its EVs, Tesla reckons it knows enough about batteries to solve a key problem in the solar energy chain -- namely the storage of power for use when the sun, power grid, or both go offline. The battery design, consisting of many laptop-style lithium ion batteries stacked together, was chosen after two years of research and a $1.8 million energy grant. The two companies are now waiting for tax credits from the Fed and California before rolling out the tech. And being kissing cousins -- with Elon Musk as both Chairman of SolarCity and CEO of Tesla -- certainly can't hurt.

    Panasonic has been touting its eco-minded efforts for quite some time now, but it's gone one step further at the currently-happening Fortune Brainstorm Green Conference. The company has announced the formation of a new Eco Solutions business unit, which will be focused on "end-to-end energy solutions" for the United States and Canada. Things remain a bit vague beyond that, but the company will apparently help design, implement and finance various renewable and energy efficient projects, and Panasonic hopes that the new unit will help it become "the leader in green innovation in the electronics industry by 2018." It does have one firm commitment to get things started though; the new division has partnered with the Denver-based Renewable Social Benefit Funds to develop commercial-scale solar projects in North America -- something Panasonic itself already has a fair bit of experience with.

    Japan is often on the cutting edge of technology, but one of the things it apparently does not have is a collection of large solar power plants. Kyocera, better known state side for its interesting cell phone designs, is looking to change that by teaming up with IHI and Mizuho Corporate Bank on a large facility in Kagoshima City. The 314 acre sun farm will collect solar rays on 290,000 Kyocera-built panels capable of generating 70 megawatts of electricity, increasing the country's sun-powered production by almost 40-percent and keeping roughly 22,000 homes thoroughly juiced. The project can't quite match some of the largest such plants here in the US, but it will go a long way towards getting the island nation back on track following the fallout of the tsunami. The ¥25 billion ($309 million) construction is expected to start in July. For more info check out the PR after the break.

    A team of German researchers is working on technology that could let you ski all day without worrying about your smartphone battery, says a report in GlobalPost. Scientists from the Fraunhofer Institute in Berlin, TEXSYS and the Technical University in Berlin have created a solar helmet that charges your mobile device while you ski. The helmet has a curved solar panel skin, integrated headphones and a microphone so you can use your phone or mp3 player on the slopes. They've also designed a special set of gloves that can control your mobile device. Though it might not appeal to your casual, recreational skier, this solar system could be useful for adventurers who need extra juice for a long day mountaineering as well as mountain rescue teams who would appreciate the always-on communication.

  • Delaware Ph.D. student hopes to solve energy woes with renewable hydrogen production

    Hydrogen fuel is a fickle mistress. On one hand, it teases us with the promise of renewable energy and a cleaner tomorrow. On the other hand, it's most often produced with natural gas as the source -- hardly the clean break from fossil fuels that many had envisioned. Fortunately, there are other methods to harness this abundant element, and a doctoral student at the University of Delaware may have created a worthwhile process. Similar to previous research we've seen -- which relies on ceric oxide and energy from the sun -- Eric Koepf has designed a reactor that combines zinc oxide powder, solar rays and water to derive hydrogen as a storable energy source. Most intriguing, it's thought that the zinc oxide byproduct from the reaction will be reusable -- a potential gateway to sustainable energy. Koepf will spend the next six weeks in Zurich at the Swiss Federal Institute of Technology, where his reactor prototype will be put through its paces to determine its efficiency and effectiveness. If successful, his advisors envision that one day, we may see giant versions of Koepf's reactors producing hydrogen on an industrial scale. We certainly won't fault them for dreaming big.

    You've probably heard that the sun is strong enough to power our planet many times over, but without a practical method of harnessing that energy, there's no way to take full advantage. An incredibly thin and light solar cell could go a long way to accomplishing that on a smaller scale, however, making the latest device from researchers from the University of Austria and the University of Tokyo a fairly significant discovery. Scientists were able to create an ultra-thin solar cell that measures just 1.9 micrometers thick -- roughly one-tenth the size of the next device. Not only is the sample slim -- composed of electrodes mounted on plastic foil, rather than glass -- it's also incredibly flexible, able to be wrapped around a single strand of human hair (which, believe it or not, is nearly 20 times thicker). The scalable cell could replace batteries in lighting, display and medical applications, and may be ready to be put to use in as few as five years. There's a bounty of physical measurement and efficiency data at the source link below, so grab those reading glasses and click on past the break.

  • Powering an iPhone 4/4S with the sun: Etón's Mobius solar battery case

    There are times where you absolutely need to charge up your iPhone 4 or 4S, but you're nowhere near a power outlet. In those situations, you might fall back upon an iPhone battery case like the trusty Mophie Juice Pack Air I carry with me, but what happens when that battery runs out? No problem, as long as you're carrying the Etón Mobius (US$80) rechargeable battery case with a solar panel and it's a sunny day. The Mobius has a hefty capacity -- 1800 mAh -- and can be charged the time-honored way by plugging it into a USB port. But for those times where you're hiking, biking, camping or just not near a power outlet, you can place the case into the sunlight to charge the battery pack. Since your iPhone (and any other mobile phone) can react badly to exposure to laying in the sun, Etón recommends taking the Mobius off of the iPhone before setting it in a sunny place for charging. Especially with the black Mobius case, you'll want to take care picking it up after it's been sitting in the sun for a while as it can get quite warm. %Gallery-151365% One hour of sunlight is enough to help you out of a jam, providing 25 minutes of talk time, 20 minutes of 3G internet use, 35 minutes of video playback, or 145 minutes of audio playback. If you leave the Mobius in the sun long enough to get a full charge (Etón does not give an estimate of full charge time as it is dependent on a number of factors), your iPhone gets another 5 hours of talk time, 8 hours of 3G internet, 8 hours of video playback, or 32 hours of audio playback. As you'd expect with any device that has an internal battery, the Mobius has some bulk to it. The case is 2.44" x 5.1" x 0.875" (61.9 x 129.5 x 22.2 mm) in size and adds 3.4 ounces (96.4 gm) to the weight of your iPhone. By comparison, that Mophie Juice Pack Air I was referring to earlier has the same price tag, only a 1500 mAh battery, doesn't offer solar charging, adds 2.5 ounces (71 gm) of weight, and is only about .2" (5 mm) thinner. The case comes in black and white; as you can see from the small gallery above it's a pretty standard-looking battery case. That blue high efficiency monocrystal solar panel is the one outside feature that really makes this case stand out. I did run into some issues trying to charge the Mobius by placing it in a window. Although the window was in full direct sunlight, the device failed to charge. I'm assuming that it was because of the anti-UV coatings on my windows, since it did charge nicely when I put it outside in the bright Colorado sunshine. Even if you don't use the Mobius as your regular day-to-day iPhone case and battery pack, it can be a useful addition to an emergency preparedness kit. Having the ability to charge your iPhone when the power's out or you're stuck in the car somewhere could be a lifesaver.

    In Insert Coin, we look at an exciting new tech project that requires funding before it can hit production. If you'd like to pitch a project, please send us a tip with "Insert Coin" as the subject line. Have any immediate plans to go to war, escape nuclear fallout or get shipwrecked in the middle of the Pacific? Boy has Snow Lizard got the iPhone case for you. The Aqua Tek S is rugged, waterproof, battery-powered, solar panel-packing and in some cases camouflaged -- all said, it looks to be a beast of an iPhone 4 / 4S case that'll make your Otterbox case look like Samuel L. Jackson in Unbreakable. The twist ending here is that the case is currently seeking funding over on Kickstarter, with less than a month to reach its lofty goal of $75,000. When it hits, it's expected to run a pricey $130. Press info and a video of the case in action, after the jump.
