Tesla Roadster 2.5 gets 119 MPGe rating from EPA, still as expensive as ever (updated)

Move over, Nissan, because there's a new MPGe king in town. Yesterday, the EPA anointed Tesla scored its Roadster 2.5 with an MPGe rating of 119, which would make it the most fuel-efficient car on the market. That places the plug-in ahead of both the Nissan Leaf (99 MPGe) and Chevy Volt (93 MPGe). According to the government-approved mock-up window sticker, Tesla's EV can last for up to 245 miles on a single, eight-hour charge, while getting the equivalent of 112 miles per gallon on the highway and 124 in the city. The original Roadster, meanwhile, received an MPGe score of 111 yesterday, with ratings of 105 on the open road and 116 in the city. Both models scored a perfect 10 for their greenhouse gas and smog emissions, though those ratings probably didn't factor in all the cash you'd have to burn to actually buy one.

Update: We just heard from the EPA, which clarified that this is not their official rating for the Roadster 2.5. These numbers are Tesla's, and the window sticker itself is a mockup - not a legitimate sticker from the EPA. Still, if you'd like to see it, it's down after the break.

Barnes & Noble clarifies battery life on new Nook, calls out Kindle

Wondering which electronic reader reigns supreme when it comes to extreme battery life? If you ask Amazon, it's the Kindle, but Barnes & Noble begs to differ -- and it has some numbers to back that up. Earlier today we received a statement from the company explaining just how thrifty the new Nook is when it comes to sipping from cells. With WiFi disabled on both devices, B&N says it managed 150 hours on the new Nook when turning a page every minute. The current-gen Kindle, meanwhile, petered out after 56. That's almost three times as long and maybe, just maybe, enough to finally get you through Anna Karenina on one charge -- or at least through the Cliffs Notes version. More details on the testing overview below, which we promise can be rather more rapidly ingested.

With up to two months on a single charge, the All-New NOOK has the longest-battery life in the industry and superior battery performance to Kindle 3. In our side-by-side tests, under the exact same conditions, continuous use of the device resulted in more than two times Kindle's battery life. While reading at one page a minute, the All-New NOOK battery lasts for 150 hours where the Kindle battery, using the same page-turn rate, lasts for only 56 hours (both with Wi-Fi off). We've also done a continuous page turn test and at one page turn per second, the All-New NOOK offers more than 25,000 continuous page turns on a single charge.

Third Rail iPhone case has detachable battery, probably won't electrocute you

For humans, coming into contact with the third rail will likely void your personal lifetime warranty, but one accessory manufacturer hopes to apply a similar concept to your iPhone -- in much smaller doses, of course. For $90, the Third Rail System includes an iPhone 4 Slim Case, which always surrounds your device, and a 1250 mAh Smart Battery that you can slide into place whenever you need a boost. The removable batteries can charge other devices over micro USB, and can be stacked up to four deep for charging multiple gadgets at once (at $60 a pop). It's also designed to be compatible with future cases, negating the need to purchase another complete solution each time you upgrade your phone. We'd love to see a similar device that includes inductive charging as well, but for now, this is one of the most intuitive external battery solutions we've seen.

FCC reveals Seagate GoFlex Satellite, a WiFi-capable battery-powered external hard drive

For a purportedly doomed manufacturer of magnetic storage, Seagate sure is spinning some interesting ideas these days -- last year, we got modular, upgradable cables, and now the company's testing external hard drives that don't need pesky wires to function. According to filings, the Seagate GoFlex Satellite not only plays the network-attached-storage card with built-in 802.11 b/g/n WiFi, it's also got a 3.7V battery inside its case... making the product's name somewhat apt, don't you think? According to a leaked description, Seagate's also planning a companion iOS app called "GoFlex Media" to let your iDevices stream content directly from the device. Mind you, none of that means you won't be able to dock with your Satellite the old-fashioned way -- FCC docs also mention a USB 3.0 cable that delivers data and power simultaneously.

HTC Thunderbolt inductive charging back hits FCC, makes life with LTE a little easier

That inductive-charging backplate for the HTC Thunderbolt just hit the FCC, which means keeping the battery-devouring device juiced is about to get a little less inconvenient. Instead of having to plug in three times a day just to keep that LTE radio happy you'll simply be able to rest it on a charging mat... three times a day. The part made a brief appearance in the Verizon shop for $39, but the rumored April release date came and went without so much as a peep from Big Red. While we still can't say for sure when it will land, at least we know it's coming sooner rather than later -- and we've got one less reason to reconsider that pocket-busting extended battery.
