The greening of homes and gadgets is a growing consumer trend, and many exhibitors will debut their eco-friendly products at CES 2010. Last week, we highlighted the Electronic Houskeeper and the PICOwatt, two devices that monitor in-home energy use. Today allows us to highlight the Surge, an iPhone and iPod Touch case with solar panels.

Solar chargers like Solio are chunky and need to be carried around. But the Surge solar case is sleek, ergonomic, and certified by Apple. Two hours of sun exposure power 30-60 minutes of talk time. The Surge features an LED battery-level indicator.

The charger is manufactured by Novothink, a company that vies to pair solar technology and portable devices. The California-based company is focused on creating solar chargers for devices in high demand, as the mission is to allow consumers to live off the grid easily.

The Surge may seem like a gimmick on the face of it, but it might be a perfect solution for Apple iPhone and iPod owners on the go. Emergency chargers are available, but those are often cumbersome, especially for men, who generally don't have the luxury of a purse for portable storage.

Those looking to harness the sun's energy will have to fork over $70, but it could be the right investment for consumers on the move. Novothink has already released the Surge for the iPod Touch and will make it available to iPhone users on December 15.

The iStetho Adapter converts an old stethoscope into an electronic one using an iPhone or iPod Touch and the iStethoscope Pro app.

If you're the kind of person who likes to take scissors to old gadgets, this one's for you. Start-up RidRx is now selling an adapter to connect old stethoscopes to an iPhone or iPod Touch, along with a phone dock/holder and an app that translates the audio your stethoscope captures into such delightful digital accoutrements as sound spectrograms.

And yes, the firm's easy-to-follow instructions include taking trauma shears to your old 'scope to fit it to the patent-pending iStetho Adapter. So the whole process, from tinkering with hardware to taking current heart-rate readings with the iStethoscope Pro app, promises to be a heart-healthy thrill.

Medgadget, which reported on the release of the adapter on Tuesday morning, is also publishing the following disclaimer:

U.S. FDA and other regulatory agencies are far behind the times that we live in, so they have no current policies to deal with the proliferation of mobile computing devices and their potential uses in medicine. Hence, none of the iPhone applications and attachments are classified as medical devices, so they are sold for nonmedical uses only.

In other words, the adapter can really only be marketed for recreational use. Still, I can see a wide range of medical applications for such a mobile stethoscope, including measuring the effect on my own cardiovascular health of the Microsoft vs. Mac comments that could very well somehow manage to work their way into this thread... (Ahem.)

For an informative, quiet, and ultimately entertaining tutorial on how to use the app, watch The Undercover Scientist's presentation below:

For a "limited time," the adapter is $29.99. And if you don't have an old stethoscope lying around, you can pick up their recommended Trimline stethoscope for $79.99. The app itself, which has been available for a few months, will set you back 99 cents.

Hive for the iPhone: brilliant fun

Back when I used to work at Sony Online Entertainment many, many years ago, I became a board game geek. The game designers and producers gathered once a week to share their sizable collections and obscure finds up in Mira Mesa, Calif., and I got hooked. The fact that the Game Keeper chain of stores was simultaneously going out of business and liquidating their supplies encouraged me to start building my own game cabinet, and I profess without shame that I rapidly became a full-blown board game geek.

I still like hunting for new games, and a few years ago at the New York Toy Fair I came across the brilliant and simple tile-based game called Hive.

Like a cross between chess and dominos, Hive's hexagonal pieces are shaped like insects, each of which can move differently on their mission to surround the opponent's queen bee. I tried to order Hive online but it wasn't available, and no local game retailer would stock it. I finally found the game in a small town in Devon, England, while visiting my in-laws, and paid close to $35 for it.

This long story comes to a quick point: I found Hive on the iPhone App Store last week for $4.99, and instantly bought it. I hope this trend continues, and it should.

Hive joins my collection of Settlers of Catan, Go, Mancala, and what I'm sure will be many, many more board games shrunken to pocket-size on my iPhone. It's wonderful, and I feel like it's groundbreaking, too.

Board games on the iPhone

While game systems like the Nintendo DS and PSP have had a variety of fantastic titles, they'd certainly never proceed into European board games. The low overhead and microprices on Apple's ever-enormous App Store becomes, for both developers and consumers, a great live petri dish to grow a new legion of board game fans.

Ever wondered what some of the graphical differences are in games that make use of the newer hardware in the latest versions of Apple's iPhone and iPod Touch? So were we. That's why we put together a screenshot comparison gallery of 13 games, all of which are either packing extra OpenGL ES 2.0 goodies, or that more complicated graphics modes that run a whole lot better on the beefier hardware spec.

As for our testing, we ran each title on an iPhone 3G and a third-generation iPod Touch, the latter of which packs the faster innards required for some of the advanced OpenGL effects.

To our surprise, there were very few apps on the App Store that made use the new graphical spec, and even fewer that required a standalone version of that application to do so. However, many of the developers we talked with said that they were cooking up new titles that would be pushing these new devices a little further than what they had already created. That's good news for those with a newer iPhone or iPod Touch, but a definite thorn in the side of those who might not be able to play some of near-future App Store releases on their original iPhone or iPhone 3G.

Click on our slideshow link below to get started. We've also included links to each version of each app (in case there are variations), all of which open up in iTunes. Also, in case we missed any, feel free to leave them in the comments and we'll try to add them later.

Update: We've added bonus screenshots of Ravensword, the upcoming 3D RPG, as well as top-down pinball game Wild West Pinball.

New 3D games are available for Zune HD owners, and they're all free.

Zune HD owners have something to smile about today. The latest firmware update, version 4.3, not only brings a handful of general fixes (including accurate playcounts), but also ushers the Zune HD into a proper 3D gaming device.

To celebrate the new capability, six new games have been added to the Zune Marketplace software, which users can download to their updated Zune HD at no cost. Games include PGR: Ferrari Edition, Lucky Lane Bowling, Vans Sk8: Pool Service, Piano, Checkers, and Audiosurf: Tilt. We're not exactly jumping out of our seat over Piano and Checkers, but the rest of the titles look genuinely fun--and did we mention they're free?.

Just like the existing games available for the Zune HD, the new titles also show a brief advertisement upon start-up.

A news release e-mailed to us from Microsoft also states "we will be delivering additional applications for Zune HD including Facebook and Twitter in the future."

So you've managed to get your hands on one of the world's most sought-after MP3 players, the Apple iPod Touch. This sleek and innovative device will keep you plenty entertained for sure--especially with new music apps from Pandora and AOL adding Internet radio capability--but you'll soon realize that a little extra investment can help you get the most out of your player.

For one thing, those stock Apple earbuds aren't the best-sounding--or most comfortable--headphones to be had. The first step is to upgrade, and our top headphones list is an excellent place to start. Pay special attention to models with built-in mics, such as the Klipsch Image S4i, which not only allow you to take advantage of the player's voice apps but also include an inline remote with playback controls.

Once you get your music piping through some decent headphones, check out some other add-ons that can help you protect and enhance your player. Also, don't overlook the player's value in terms of home audio and be sure to check out our top iPod speakers.

The iPhone gets HD radio.

Staying competitive in an iPod-ruled marketplace is a challenge, and not just because of the player's built-in virtues (or Apple's massive marketing budget). The reigning king of the MP3 players has an advantage simply because it resides at the top of the heap, and that advantage comes in the form of feature-adding third-party accessories. Case in point: the Gigaware In-Line Remote with HD Radio, an $80 add-on for the iPhone and iPod Touch.

That's right, kids...that would be the iPod addressing a major selling point and advantage of the Zune HD. Please don't act surprised. You knew this day was coming. And yes, the Gigaware remote does allow display of track information on the iPod screen as well as song tagging, which let's you find songs easily for later purchase.

So let's recap: 32GB Zune HD costs $289; 32GB iPod Touch with HD radio addition costs $379. Not exactly apples to apples, but which one do you find more attractive? Does HD radio even matter? Discuss.

In news that shouldn't come as a shock to anyone who's perused our Holiday Gift guide, sampled our list of top MP3 players, or remembers what happened to last year's iPod Touch, the third-generation iPod Touch now proudly bears the CNET Editors' Choice badge.

As I mentioned back in September, I deliberately held off on awarding the Touch an Editors' Choice early on, waiting to see what Archos and Zune had up their sleeves before handing down final judgment. Well, all the reviews are in now and the iPod Touch remains king of the hill. Whether you're buying one for yourself or giving it as a gift, the third-generation iPod Touch does not disappoint.

To all you Zune HD fans out there who feel betrayed by our choice, feel free to pour your anger into the comments section below.
