Netgear Push2TV Links Your Laptop to Your TV, Sans Wires (Sorta) [Television]

With digital content becoming more prevalent, some of us want to directly link our computers to our TVs quickly and easily. But we don't all have a dedicated HTPC to make life simple. Enter Netgear's Push2TV wireless display adapter.

Netgear's solution involves the use of a box which picks up a signal from your laptop and feeds your desktop to the TV via HDMI, eliminating the need for your lappy to be tethered to your entertainment center. The only downside is that it requires an Intel-based computer with Wireless Display technology built in.

Push2TV will be available this month, bundled with select laptops at Best Buy, or sold separately for $100. Dongle plz? [Netgear]

Monsoon Volcano Is Like a Slingbox and Slingcatcher Rolled Up Into One [Streaming Media]

Dave Zatz got an early peek at Monsoon's new video placeshifter, the Volcano, and was pleasantly surprised by its feature set, which combines the functionality of a Slingbox with that of a Slingcatcher. Oh, reeaaaallly?

The Volcano can stream media from any TV or video source at 720p to PCs and cellphones, including the Android, WinMo, Blackberry and iPhone platforms. It can also playback local media via USB using the UPnP and DLNA standards, web video via YouTube and Cinema Now, plus it can off load shows from your settop box for later viewing/streaming.

But where it starts to get cool is how if you have more than one Volcano in your house, they can all stream to eachother, thanks to 802.11n and UPNP, which is nice if some rooms have a TV, but no cable connection. Zatz says the tech is still a bit unpolished, but calls it promising nonetheless. The Volcano is scheduled for a March release, and you can either get a model with 4 gigs of flash storage for $200, or one with a 250 gig HDD for $300.

Vizio Lifestyle Headphones Annoy Everyone Else on the Subway [Headphones]

Vizio's conceptual (but candidate for release) headphones have an LCD on both earpiece that can display a visualizer, album art, or picture of your cat, because the people around you really need to be subjected to that.

The headphones will be Bluetooth-enabled, so no cords muck up your affront to style. We don't know anything like pricing or availability, since they're still in the concept stage, but they're totally functional and may well see release. [Vizio]



Album2 Hands On: A Media Viewer That Frees File Sharing From The Computer [Album2]

With a 7" screen and a book-like form factor, the Album2 is well suited for sharing your digital files in a non-digital setting. It was satisfying to hold, simple to navigate and kept the emphasis on content.

Instead of audio, video, and images, the Album2 sorts your media in terms of the actions "Watch," "Look," and "Listen." But it doesn't seem like it's dumbing things down as much as it is simplifying them: the Album2 achieves a delicate balance between being a technically competent media viewer and a device that lets people enjoy their digital content without worrying about the device displaying it.

You can throw pictures, video, or audio in all the common formats onto the Album2's 4GB HD via USB or SD, or access content from Facebook, YouTube, Flickr and other big name sites via WiFi. The three simple buttons on the right side of the viewer were the only controls, and it's hard for me to imagine anyone who couldn't figure out the UI right away.

A leather cover attaches magnetically to the back of the Album2 and folds over as a stand, letting you rest the viewer on table like a digital photo frame. Whether standing on its own or being passed between friends, it's nice to see a gadget that is focused on fostering physical interaction based on the digital media we collect.

The Album2 will be available in Q2 2010 with a pricetag of $199. [Album Life]



Hands On With Compal’s Tegra 2 Android Tablet [Android]

No major companies are quite ready to bring a proper Android tablet to market, but they're edging closer. When they do, they could do worse than turn out something like this 7-inch, Tegra 2 design from Compal.

Under the hood is Nvidia's newest Tegra, which guarantees snappy interface, video and graphics performance in theory. In practice, at least on this early device which can't leverage the new graphics acceleration in Android 2.1, menu transitions are still a little slow, browser scrolling isn't instant, and the responsiveness of the touch keyboard poor enough to make typing a genuine pain in the ass. But wait wait wait—that's a software optimization issue, which can almost definitely be fixed. What about the concept?

The Archos 5 Android tablet, had its issues, from lack of 3G support to inability to play Flash content, both of which have been remedied here—this Compal has a SIM tray as well as Flash 10.1 support. A shipped product would be faster than the Archos, and the extra two inches of screen are just enough to make this feel like a tablet, not an oversized smartphone. And to be honest, I could get into this.

It's a sofa tablet, a toilet tablet, a Skype tablet, whatever—there's a market for this, at the right price. The only serious issue now is that typing on the onscreen keyboard is almost impossible on a 7-inch screen, unless your thumbs are freakishly long. I have no idea how Google—or Apple, for that matter—could solve this problem. But someone might! And that would be great.



Hands On: Use the Yogen Charger to Power Gadgets With a String Pull [Yogen]

We were pretty intrigued by the Yogen manual charger concept we saw earlier. While the production unit we saw today is markedly different—it doesn't disappoint. Instead of charging gadgets with a pedal, users now pull a chord.

Charging devices while pulling the string takes just as long as charging them via wall outlet so it won't replace plugging in, but in a pinch the compact device could be a life saver. There is super-low resistance in the chord so continuously pulling the string to charge isn't much of a chore (just tedious). The device is available now directly from Yogen for $39.99.

Using the Air as a Waste Dump

This visualization is a time-series of the global distribution and variation of the concentration of mid-tropospheric carbon dioxide observed by the Atmospheric Infrared Sounder (AIRS) on the NASA Aqua spacecraft. For comparison, it is overlain by a graph of the seasonal variation and interannual increase of carbon dioxide observed at the Mauna Loa, Hawaii observatory. This is nothing less than the people on earth using the sky as a toxic dump for waste from their energy and transportation sources. How could anyone think this is OK and would have no consequences? This visualization was done in late 2009.
