Inhabitat’s Week In Green: solar panels, solar planes, solar trains

The Week in Green is a new item from our friends at Inhabitat, recapping the week’s most interesting green developments and clean tech news for us.

It was an interesting week in green tech, as Inhabitat explored the past and future of solar technology. We dug up the world’s first modern solar panel (still working after 60 years!) and wrapped our brains around MIT’s plan to create super-efficient photovoltaic panels by folding them up like origami. Not to be outdone, IBM unveiled plans to roll out a new solar desalination system that could transform entire expanses of desert into rivers.

Solar power also took to the skies this week as the Solar Impulse plane made its first successful flight. And speaking of futuristic transportation, Minority Report-style podcars may be just around the corner if this solar powered urban transit system takes off. We were wowed by Finland’s new all-electric supercar, which will be vying for the Progressive Auto X Prize this summer.

We also took a look at several innovative kid-friendly designs including an incredible Game Boy made from paper and a biometric baby monitoring alarm clock that lets parents monitor their babies’ temperature and heart-rate remotely, as well as cue up lullabies from anywhere.

The past week also produced several promising developments from the realm of energy storage as Hitachi announced that it’s developing lithium-ion batteries that last twice as long. And finally, meet BOB, a battery the size of a building that is capable of powering an entire town in Texas. The gigantic sodium sulfur backup battery can store up to 4 megawatts of power for up to 8 hours.

Hitachi claims secret chemical formula will improve cathodes, double battery life

Before lithium-ion batteries, portable gadgets were a nightmare, forcing road warriors and Discman-toting teens to either swap disposable cells or deal with rechargables that (with few exceptions) were tricky to recharge. Of course, Li-ion batteries also have a downside: as laptop and cell phone users have no doubt found out, they too become disposable before long. One reason why is that acid in the electrolyte can corrode the cathode material — and now, Hitachi claims it’s found a way to strengthen its own. Using an undisclosed combination of elements to replace some of the manganese used in the company’s cathodes, Hitachi claims they can strengthen their crystalline configuration to resist acid, reduce cost, and best of all, double effective battery life to about ten years. We’ve heard similar claims before, of course, with other battery manufacturers promising us twenty years, but it looks like this technology might make it out of the lab. NEDO, a Japanese government organization, has commissioned Hitachi to bring these batteries to life for industrial applications like wind farms. Cell phones, sadly, will have to wait.

Dual Electronics iPod touch GPS cradle review

The notion of an iPod touch GPS cradle has two big factors working against it from the start. For one, dedicated navigation units are readily available for as little as $100 (or less) and, in general, get the job done quite well. Secondly, more and more cellphones are becoming more and more capable as navigation devices and, again, are relatively inexpensive (phone contracts aside). On the other hand, a lot of people have iPod touches, and most of them really like their iPod touches. So, in that respect, there is a potentially big market for something like Dual Electronics new iPod touch GPS cradle. Will it actually help carve out a new niche in the crowded navigation market? Read on to find out.

Casio’s solar-powered Pathfinder watch plays the green card twice

Plotting their latest spread of watches this spring, Casio executives decided it was time to “go green.” Some poor schmuck in R&D took them at their word. Thankfully for mother nature, the Casio Pathfinder PRG110C-3 is more than meets the eye; the watch — suited for argonauts needing an altimeter, barometer, thermometer and digital compass — also has a miniature solar cell built into its face to automatically recharge the battery. Though Casio’s claim that this last will cut down on the three billion batteries Americans trash each year seems a little reaching — watch batteries last a lot longer than a AA — the timepiece does help the planet some merely by being packaged in recyclables. The $250 device will be available exclusively from Amazon, and yeah, the color you see here is the color you’ll get.

ExoPC delayed till summer, getting specification upgrades to dull the pain

Now that the tablet PC revolution is upon us (for the second time in as many decades, if you’ll recall), there’s bound to be a few that really stick out, and a few that get left in the dust. ExoPC is doing its darnedest to be grouped in the former, and it’s choosing to hold off on rushing things out in hopes of delivering a superior product to the world this summer. If you’ll recall, we heard that the 8.9-inch slate would originally be out and about this month, but the company’s own Jean-Baptiste Martinoli has informed us directly why the ship date is being pushed back a few months. For starters, production has been shifted from China into Canada thanks to a freshly signed deal with CiaraTech. And if you’re wondering what you’ll get in return for waiting just a few more months to get your hands on one, we’ve excellent news. Here’s the good word straight from the outfit:

“With [CiaraTech’s] help we are improving the specs: better processor, graphics, better battery life, thinner, better screen and touch panel. We should hit FCC soon. As we have more time we are adding more features in the ExoPC UI Layer (ex. an app / media store).”

We aren’t exactly big on waiting, but we’ll let that other tablet keep us company until this one finally gets its shipping papers. Summer ain’t too far out, now is it?

Stanford develops safer lithium-sulfur batteries with four times the charge of lithium-ion cells

Longer battery life is high atop our list of gadget prayers, and the brainiacs at Stanford are one step closer to making our dreams come true with a new lithium-sulfur technology. Half of this trick lies in the silicon nanowire anode that the same team developed back in 2007, whereas the new cathode consists of a similarly commodious lithium sulfide nanostructure. Compared to present lithium-ion batteries, Stanford’s design is “significantly safer” and currently achieves 80 percent more capacity, but it’s nowhere near commercial launch with just 40 to 50 charge cycles (Li-ion does “300 to 500”) due to the compound’s rapid degradation. That said, we’re promised a theoretical quadruple boost in capacity as the technology matures, so until then we’ll keep that hamster running in our backpack.

Dead iPad battery? Never mind replacing it, Apple just sends another iPad for $99

Whoa, Nelly! Isn’t this something? Apple has just posted details on its iPad battery replacement service, which is really not a battery replacement service at all. Check out the company’s opening line:

“If your iPad requires service due to the battery’s diminished ability to hold an electrical charge, Apple will replace your iPad for a service fee.”

Now, let’s compare that to the verbiage found in the iPhone’s battery replacement program details:

“If your iPhone requires service only because the battery’s ability to hold an electrical charge has diminished, Apple will service your iPhone for a service fee.”

We can see the puzzled look on your face from here, and we’re sharing in the same disbelief. Apple is actually saying that it won’t bother cracking open your withered iPad, replacing the battery and sending it back your way; instead, you’ll pay $105.95 (including shipping) for a completely different iPad, which certainly has its pros and cons. On one hand, you’re getting a new (or potentially refurbished, actually) iPad in around “one week,” but on the other, you’ll be waving goodbye to every morsel of personal data on the device that you send in — unless you backup beforehand, of course. Here’s Apple’s take on answering “will the data on my iPad be preserved?”

No. You will receive a replacement iPad that will not contain any of your personal data. Before you submit your iPad for service, it is important to sync your iPad with iTunes to back up your contacts, calendars, email account settings, bookmarks, apps, etc. Apple is not responsible for the loss of information when servicing your iPad.”

Lovely, don’tcha think? Head on past the break for the full text.

[Thanks, David]

Scientists discover method for rapid charging Li-ion batteries

Huzzah! Yet another discovery for us to add to our ever-expanding list of “awesome things that’ll never actually happen!” Ibrahim Abou Hamad and colleagues from Mississippi State University have reportedly devised a method of charging batteries that could hasten the process rather significantly, and better still, it could provide “an increase in battery power densities” as well. The only problem? Lithium-ion batteries have been disappointing tech users for years, and so long as Energizer and Duracell are calling the shots, we kind of doubt a lot will be done to improve the longevity of ’em. Skepticism aside, the new method involves some fancy black magic surrounding molecular dynamics simulations, and researchers have found a way to boost charging time by “simulating the intercalation of lithium ions into the battery’s graphite anode.” We know we just went way over your heads on a Friday afternoon, but if techobabble’s your thing, all you can handle is right there in the Source link.

MSI Wind Lasts 15-Hours On One Charge

imageb

MSI’s new Wind netbook uses the low-power Intel Atom N450 “Pine Trail” CPU and manages to get an almost ridiculous 15-hours of battery life. Even if we viciously slash that time in half, to simulate real-life use, seven hours is impressive on a mere six-cell battery, and we’d expect something close to ten.

The specs are otherwise similar to all other netbooks: 10-inch display, 160GB hard drive, a gig of RAM and Windows 7. But the case itself features some rather neat additions. First, it comes in gold (or black), has a glowing MSI logo on the back, and the power button sits in the hinge – hardly useful, but certainly cool-looking. Best is the big trackpad, which has no edges and just disappears into the main body of the computer. The keyboard is more stylish, too, featuring MacBook-alike chiclets. MSI has even made the comma and period keys the right size instead of the tiny vestigial buttons on the original Wind.

The U160 is $430. That’s not bad, but we have a feeling that a certain $500 “tablet” computer might cause the netbook market to be even less attractive than it is already.

Sanyo Eneloop lite Ni-MH rechargeable batteries are cheap, less filling

If you’re a gadget fan (and let’s face it: you are) then there’s simply no excuse for using disposable batteries. Environmental concerns aside, rechargeables have advanced such that it just makes economic sense to switch. We’ve been unapologetic fans of Sanyo’s Eneloop series of Ni-MH batteries for years. Hell, we like any modern rechargeable that’s sold fully charged and is capable of maintaining that state even after years inside the family junk drawer. Today, Sanyo is announcing its Eneloop lite series scheduled for a June 22nd launch in Japan with a global release set for sometime later. These cells are meant to tempt you by their relatively low, up-front purchase price of ¥780 (about $8.64) for a pair of 1.2V 950mAh AAs or ¥640 ($7.09) for a pair of 1.2V 550mAh AAAs — each capable of about 2,000 recharges saving you at least $1,000 over their lifetime. They’re not going to power your hotshoe flash but they will handle the relatively low to medium power requirements of all the remote controls in your life. Do it.
