Portable Solar Powered Speaker

We live in a world where just about any mobile device that one carries these days – be they smartphones or tablets, are capable of playing back some music. And the amount of storage that these portable devices hold can reach insane levels, in fact, a whole lot more than your regular hard drive back in 2000. This would mean you would be spoilt for choice when it comes to the amount of songs that you can listen to, and chances are you would not have enough time to go through the entire playlist in a single setting. The thing is, sometimes, you want to share your eclectic taste in music with your mates, and your smartphone’s speaker just ain’t cutting it. Good thing there are alternatives out there like the $99.95 Portable Solar Powered Speaker.

The Portable Solar Powered Speaker not only lets you share your favorite tunes with the general public within an acceptable radius, but as its name implies, it is capable of offering an infinite amount of charging for your compatible power hungry devices – as long as the sun shines, that is. The speaker would pair up with a Bluetooth-enabled smartphone, tablet, or other wireless music player, where audio is played back via a 2.5”, 3-watt full-range speaker which delivers crisp sound. Its rechargeable battery has been rated to deliver up to eight hours of operation from a five-hour charge thanks to its built-in solar panel, and it comes with a rugged, water-resistant IPX4-rated exterior to boot.

Inhabitat’s Week in Green: Darth Vader lamp, 3D-printed inchworm and a cheap invisibility cloak

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.

DNP Inhabitat's Week in Green TKTKT

As scientists and renewable-energy developers continue to make advances in solar and wind technology, it’s becoming more apparent than ever that clean energy doesn’t just represent the future — it’s also the present. Spain proved that this week, when the Mediterranean country announced that it produced an impressive 54 percent of its total energy in April from renewable sources. Researchers at Yale University discovered a way to boost the efficiency of solar cells by 38 percent simply by coating them with a fluorescent dye. In another promising development, scientists at the University of Georgia developed a way to harness the photosynthetic process to generate clean energy from plants. And at a conference in California, NRG unveiled a mini prefabricated solar canopy that could soak up rays in any garden or commercial lot.

Sherpa 50 Solar Charger Keeps Your Gadgets Powered up, away from the Outlet

If you’re on the go a lot, away from a power outlet you may have tried all sorts of things to help get more run time from your gadgets. A new solar power kit has turned up and features a small portable battery that can be recharged from the sun or a wall outlet. The charging kit is called the Sherpa 50.

sherpa50

The first time the Sherpa 50 turned up was during CES 2012 and it was delayed over a year and a half coming to the market. The good news is that it is here now and for $399.95(USD) you can get the complete kit including an AC inverter and a portable battery. The device can also be purchased a la carte – without the AC outlet or the solar panel, for as little as $199.95.

In addition to the standard AC outlet, the device also has a USB port for charging devices and a special port for your laptop. The battery weighs less than a bottle of water according to the manufacturer and can give you one full recharge for most laptops, and multiple recharges for other gadgets.

The battery can be charged completely in about five hours using only the included solar panel. You can also recharge the battery from the wall outlet in about three hours.

The Sherpa 50 is available now from GoalZero.

University of Georgia stops plant photosynthesis to generate solar power

University of Georgia interrupts plant photosynthesis to make truly green energy

There’s a more efficient way to harvest energy from the backyard than by wiring up hapless critters. Researchers at the University of Georgia have proof: they’ve discovered a way to generate electricity from plants through hijacking the photosynthesis process. By altering the proteins inside a plant cell’s thylakoids, which store solar energy, scientists can intercept electrons through a carbon nanotube backing that draws them away before they’re used to make sugar. While the resulting power isn’t phenomenal, it’s still two orders of magnitude better than previous methods, according to the university. The protein modification method may have a rosier future, as well: the team believes that it could eventually compete with solar cells, producing green energy in a very literal sense.

Earl Android tablet is solar powered and battle-ready

Most Android tablets are pretty much the same nowadays, traditionally. However, one company is looking to shake things up with an Android tablet that’s meant for the outdoors person in all of us. The Earl, as it’s called, is solar powered and comes with a thick robust outer shell to protect from the outdoor elements.

Screen Shot 2013-05-08 at 3.08.18 PM

The tablet is referred to as a “backcountry survival tablet,” and it comes with all the features that most hikers would want out of such a device, including the typical wireless connections including NFC, as well as GPS with topographical maps that are preloaded onto the tablet. There’s a two-way walkie-talkie built in to chat with other hikers who have an Earl tablet as well.

Screen Shot 2013-05-08 at 3.11.36 PM

The device sports a 6-inch e-ink display, so it’s certainly nothing that you would watch movies or play games on, and there’s also no camera to take photos, but we’re guessing you’d use your dedicated shooter anyway if you wanted to take photos of the beautiful scenery. It won’t be a tablet for most everyday users, but it seems that it’s an option for the survivalists.

As for price and availability, the Earl tablet is actually trying to raise money to fund its production. The tablet’s website is currently taking pre-orders at $250 a pop, which is 30% off the retail price of the tablet when it eventually launches. The company is seeking $250,000 and they’ve raised almost $13,000 so far as of this writing, with 32 days left to go.

Graphene paint aims to solar-power future homes and electronics

Scientists from the University of Manchester have discovered that by combining Graphene, a one-atom thick layer of graphite, with the transition metal dichalcogenides, a material that can react to light, they are able to create a product that can generate electricity from sunlight. They can form thin sheets of the product that can be placed on buildings to absorb sunlight and turn it into electricity.

Graphene paint aims to solar-power future homes and electronics

The product can give solar panels a run for their money, but the scientists aren’t going to stop there. They intend to find a way to use this technology to produce a paint that can be used for homes, as well as other objects. However, Professor Kostya Novoselov, one of the scientists who discovered graphene, stated that the development of the paint isn’t going to happen until much later in the future.

The graphene paint can be used to power a number of devices, with one emphasis being on mobile phones. The scientists believe that graphene paint would bring in a “new generation” of mobile phones that are solar powered and are ultra-thin. Not only can graphene paint be used to power objects, scientists believe that they will be able to make it change colors on-demand as well.

The scientists are optimistic about the development of graphene. Not only is the material harder than diamond, and able to conduct electricity, there are many more possibilities for it as well. Professor Novoselov stated that they would be able to use graphene to develop different types of products with a variety of properties other than producing solar powered energy. He states,

“We have been trying to go beyond graphene by combining with with other one atom thick materials. What we have been doing is putting different layers of these materials one on top of the other and what you get is a new type of material with a unique set of properties. It is like a book – one page contains some information but together the book is so much more. The implementations would go much further than simple solar powered cells”

Solar Impulse sets off on its journey across the US (video)

Solar Impulse sets off on its journey across the US

Early this morning at Moffet Air Field in Mountain View, California, Solar Impulse finally took off on the first leg of its barnstorming tour across the US. Of course, this isn’t the first time the sun-powered plane and its pilots, Bertrand Piccard and Andre Borschberg, have flown long distance, but it is the first time it’s taken wing through American airspace. Why has it come across the pond? To raise pubilc and political awareness about the benefits of going green and increasing energy efficiency — and perhaps pick up an additional sponsor or two for its second-gen aircraft (currently in development) meant to fly around the world in 2015. “With the technologies we have onboard, we can divide by two the energy consumption of our world, and produce half of the rest [energy we need] with renewable sources” according to Piccard.

This first portion of the journey will end in Phoenix, and it’ll take around twenty hours to get there, as the plane’s meager output limits its average speed to around 40MPH. Should any of you want to join along with Piccard and Borschberg as they fly across the country, you can hit the Solar Impulse Across America website to see a livestream from the cockpit, along with real-time altitude, air speed and battery status of the aircraft. And, you can watch a video of Solar Impulse taking off on its North American journey and hear Borschberg talk about learning to fly it after the break.

Solar Window Socket: Stick up and Plug in

If only harnessing the power of the Sun could be as simple as sticking an outlet with a solar panel onto your window. That’s the idea designers Kyuho Song and Boa Oh are pushing for with their Window Socket concept design.

Window Socket

It’s basically an outlet you fasten onto any clear window so that it charges up by absorbing the sun’s solar energy. When you want to power something up, simply stick the plug into the socket and that’s it.

window socket 2

The design description indicates that the solar energy will be transformed into electrical energy by a converter, although I can’t really see where they could have crammed that circuitry inside of the small puck-like device.

Window Socket1

I think the Window Socket is a grand idea, and it would be awesome if they actually managed to turn it into a reality.

Pilot to fly across US on solar-powered plane

A major milestone for solar technology is coming up, as one pilot will be taking on the task of flying from San Francisco to New York on a plane that’s powered only by solar energy. Bertrand Piccard will be taking off in a plane that he and his design partner André Borschberg call Solar Impulse, which has been in the works for almost 10 years.

solarimpulse-large

Solar Impulse has a wingspan of 207 feet, which is 2/3 the length of an American football field and the same wingspan as many commercial jets. The plane also sports 12,000 solar cells and 900 pounds of batteries to keep it going for a prolonged period of time. The team of two tested-flew the plane in 2010, and it was able to stay in the sky for 26 hours straight.

However, only Piccard will be making the journey across the country, but it won’t be as fast as what a commercial jet could make the trip in. Solar Impulse has a top speed of around 50 miles per hour, so it’s expected to take a few days for the plane to reach New York, whereas a jumbo jet could make the trip in just a few hours.

If the Piccard name sounds familiar, than you’re on to something (no, not Star Trek). In 1999, Piccard circled the globe in a gas-powered balloon, and his father, Jacques Piccard, was the first person to descend to the bottom of the Mariana Trench in 1960. After Piccard completes the flight across the US, his next goal is to take the plane around the entire world, just like he did with the balloon.

Space rock rips through ISS solar panel, gives hull a miss

Space is a dangerous world. Debris is flying around everywhere, including small space rocks (read: bits of asteroid or meteoroid), which means that the International Space Station is constantly prone to getting hit by these small objects, and when you’re traveling at 4.8 miles per second, even small objects can have a big impact. ISS Commander Chris Hadfield tweeted a photo of a hole in the one of the solar panels where a space rock ripped through.

BJCPKUcCAAAd3dp

Few details are known at this point, but Hadfield referred to the damage on the solar panel as a “bullet hole,” and said that he was “glad it missed the hull.” We’re not sure exactly what would happen if a small rock like that collided with the ISS hull, but judging from Hadfield’s sigh of relief, nothing good would come out of it.

We’re guessing that the hole didn’t cause too much severe damage to the solar panel, or else the ISS would be in deep trouble. We’re not sure how large the small hole is, but it doesn’t look big at all — merely a small speck compared to the sheer size of the solar panels on the station.

Of course, this isn’t the first time that Hadfield has talked about small meteoroids hitting the ISS. He hosted a Reddit AmA back in February where he discussed “micro-meteorites would sometimes hit the hull and make a loud “ping” noise, which leaves dents on the outside of the station. However, Hadfield notes that a larger piece of rock could come along and cause greater damage.
