Diffus Solar Handbag charges your cell during the day, may actually leave the closet


Sure, solar-paneled bags are occasionally practical and always geeky, but the women in our lives wouldn’t dream of letting us walk around with one, let alone using one themselves. That soon may change. The Solar Handbag from Diffus, a Danish design studio, integrates 100 “solar sequins” in a pattern that ladies may actually find socially acceptable, perhaps even attractive. During the day, the bag is capable of generating 2 watts of power, enough to charge many portable gadgets. After the sun sets, however, any leftover energy is redirected to a set of optical fibers, which glow whenever you open the bag to search for mascara, ABC gum stuffed in crumbled receipts, or whatever else you’ve decided may never leave your side. There’s no word on whether the bag will actually come to market, but if it does go to production, it may just end up being affordable, given that many handbag budgets far exceed the amount we set aside for gadgets.

Mizzou Professor says nantenna solar sheet soaks up 90 percent of the sun’s rays, puts sunscreen to shame

Photovoltaics suffer from gross inefficiency, despite incremental improvements in their power producing capabilities. According to research by a team led by a University of Missouri professor, however, newly developed nantenna-equipped solar sheets can reap more than 90 percent of the sun’s bounty — which is more than double the efficiency of existing solar technologies. Apparently, some “special high-speed electrical circuitry” is the secret sauce behind the solar breakthrough. Of course, the flexible film is currently a flight of fancy and won’t be generating juice for the public anytime soon. The professor and his pals still need capital for commercialization, but they believe a product will be ready within five years. Take your time, guys, it’s not like global warming’s getting worse.

Inhabitat’s Week in Green: floating trains, dead bees, dirt-powered phones and Cornish pasties

Each week our friends at Inhabitat recap the week’s most interesting green developments and clean tech news for us — it’s the Week in Green.

Did you know that the cell phone in your pocket could be causing the collapse of bee colonies? This week Inhabitat reported the alarming news as Swiss researchers confirmed that cell signals confuse bees and are leading to their deaths. We also looked at a Bill Gates-funded plan to power cell phones using dirt, and we spotted a new phone battery that can be charged by yelling at it — much to the chagrin of everyone else on the bus.

Alternative transportation got a boost this week as Japanese engineers unveiled a levitating high-speed electric train that flies over the earth, and we shined a light on Berkeley’s new solar-powered Impulse racer, which is gearing up to blaze a trail in the 1,800-mile World Solar Challenge. It was a big week for biofuels as well as Ford and Georgia Tech unveiled plans to create the first hydraulic hybrid U.S. school bus and UK scientists cooked up a plan to power cars with Cornish pasties.

In other news, this week a New Jersey Toys “R” Us unveiled plans to build the largest solar roof in the United States, and HyperSolar rolled out a magnifying film that can increase the efficiency of photovoltaic panels by 300%. In green lighting news, we watched Google flip the switch on its brilliant Android-controlled LED bulb, and we announced the Philips and Inhabitat Bright Ideas Lighting Design Competition, which is awarding $1,000 to the designer of the most stunning eco-friendly lamp. Finally, we got excited for the start of summer with a look at the Lapin Kulta Solar Kitchen, which will be serving up sun-cooked meals all across Europe!

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.

Inhabitat’s Week in Green: sugar-covered lamps, IKEA’s solar lamp, and the 30MPH all-wood racing bike

Each week our friends at Inhabitat recap the week’s most interesting green developments and clean tech news for us — it’s the Week in Green.

Several breakthroughs sent shock waves through the field of renewable energy this week as Inhabitat reported on a new type of “invisibility cloak” that could supercharge solar cells and researchers at MIT harnessed viruses to improve the efficiency of dye-solar cells by a full third. We also cast a keen eye on the royal wedding, which is expected to produce 6,765 tons of CO2, and we explored a new wireless charging technology being developed by Toyota and WiTricity. And if futuristic eco cities float your boat, check out this self-sustaining ecotopia designed to produce energy and food in the North Sea.

We also showcased several novel electric vehicles, including the crazy Uno 3 transforming scooter which is now available for pre-order. Alternative fuels also took off as a Kentucky man unveiled a car that runs on bourbon and a mobile greenhouse powered by renewable energy hit the streets of New York City. And from the realm of pedal-powered transportation we brought you the SplinterBike – a bicycle made entirely from wood that can hit a record-breaking 30 miles per hour.

In other news, energy-efficient lighting advanced by leaps and bounds this week as we flipped the switch on IKEA’s new solar-powered Solvinden lamp and we spotted a crystalline “Stardust” LED lamp made from sugar at the Milan Furniture Fair. Finally, we shined a spotlight on Katy Perry’s debut on American Idol as a LED-studded Extraterrestrial, and we took an exclusive look inside New York City’s first LEED gold skyscraper – the Hearst Tower!

Nanocones make solar cells more efficient, sinister looking

Going green is de rigeur, so the sun is becoming a much-preferred source of power. However, solar cells’ inefficient harvesting of heliacal energies is a major reason they haven’t usurped the power of petroleum. Good thing the big brains at Oak Ridge National Laboratory are looking to change that with nanocone-based solar technology. The teeny-tiny cones are made of zinc oxide and create “an intrinsic electric field distribution” to improve electrical charge transport within solar cells. We aren’t sure what that means, but we do know the prickly-looking design provides a 3.2 percent light-to-power conversion efficiency that’s a substantial improvement over the meager 1.8 percent offered by today’s flat photovoltaics made of similar materials. That’s 80 percent more efficient, and 100 percent more awesome.

MIT’s genetically modified viruses boost solar-cell efficiency by herding nanotubes

The wizards of MIT have done it again. Having checked artificial leaves and Operabots off the to-do list, they’ve moved on to improving the efficiency of solar cells. Their technique combines a genetically modified version of the M13 virus with carbon nanotubes, which have already been shown to increase efficiency. Unfortunately, some nanotubes enhance solar cell performance, while others inhibit it – and both types tend to clump together, negating their benefits. The modified M13 virus, however, can separate the two types as well as prevent clumping; we’ve seen similar use of the Tobacco mosaic virus to build better electrodes. Adding virus-built structures to dye-sensitized solar cells increased power conversion efficiency by almost one-third and, with only one additional step in the manufacturing process required, the new approach could be rapidly taken up by existing production facilities. MIT: proving once again that viruses are good for more than just smiting your enemies.

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]

Inhabitat’s Week in Green: solar panel roads, floating golf, and the 2,564.8 MPG race car

Each week our friends at Inhabitat recap the week’s most interesting green developments and clean tech news for us — it’s the Week in Green.

Building technology got a tremendous boost this week as Inhabitat reported on a new type of graphene super paper that is 10 times stronger than steel and six times as light. We also took a look at several remarkable new infrastructure projects popping up around the world – from a self-sufficient floating golf course in the Maldives to London’s gleaming new cable car system, to the Netherlands’ plan to supercharge its roadways with solar panels.

Speaking of hot asphalt, this week the ultra-efficient Alerion race car blazed a trail at the Shell Eco-Marathon, clocking in an incredible 2,564.8 miles per gallon. Meanwhile, Fisker announced that its sexy electric Karma sedan will hit the road this summer, and we were surprised to hear that Marcelo da Luz was forced to pull his solar-powered X of 1 car across Ontario due to road regulations. The New York Auto Show also kicked off with a blast this week as Lexus unveiled its next-gen LF-Gh concept hybrid and Porsche rolled out a 911 GTR 3 in a Facebook colorway that got a lot of “likes”.

Finally, we looked at several futuristic example of wearable technology this week including a pair of RoboCop-like glasses that are capable of scanning 400 faces per second at public events. We also brought you a brilliant LED backpack that lets cyclists send signals to drivers, a pollution-detecting t-shirt, and a clock that tells time by knitting a new scarf every year.

Newly discovered properties of light promise better solar batteries, really great tans

Are you tired of waking up to the same old semiconductor-based solar array? Do you yearn for a change? We know you do and, thanks again to the wonder and mystery of magnetic fields (they’re not just for stopping speech anymore), there’s a new day dawning. University of Michigan scientists were shooting lasers at glass, as they do, and made a remarkable discovery: light passing through a non-conductive surface like glass generates impressive magnetic effects – up to 100 million times greater than expected. The resulting magnetic force could replace the electric effect exploited by current technology, paving the way for “optical batteries.” Though different from the Wysips transparent photovoltaic cell, the technology could have similar applications and may render obsolete those massive solar farms. No need to worry, though — your stylish solar backpack is as fly as it ever was.
