We were totally digging Volvo's ReCharge plug-in hybrid concept when they were showing it off last year at the Frankfurt Motor Show, but unfortunately it wasn't much more than a cutaway demonstration model at that point. Lucky for us, Volvo decided to take it legit, and built a full-on working concept model of the Volvo C30-based car. The company is teamed up with Saab in a five-year plan to develop plug-in hybrids, and they're currently planning a fleet of 10 cars to be tested in Sweden. Volvo plans to announce a hybrid version of one or more existing models within the next five years, but they're certainly playing it safe -- though the lithium-polymer batteries and in-wheel electric motors might prove them otherwise.

According to reports, a team of scientists have developed a battery which uses "betavoltaic" cells to keep chugging along for up to 30 years without the need for a recharge. If you believe what they say (and that's a big "if"), the battery uses a non-nuclear form of radioactive material as the basis for power, and that material gives off energy as it decays. Apparently, the batteries are small and thin, and when they've cashed in their energy-producing chips, they're totally non-toxic and inert. Sound too good to be true? Well you're not alone. Rupert Goodwins, of ZDNet, cleanly separates the wheat from the chaff by pointing out a number of problems with claims being made over the batteries, pretty much dashing any real hopes that these things will end up in your next laptop. Raining on the parade, Mr. Goodwins says that the atomic structure of the cells tends to fall apart when hit with high energy electrons, the "inert" battery would still be toxic should its housing ever crack, conversion efficiency would be 25-percent (an abysmal number, which also means 75-percent is heat), and finally, the cells would weigh something like 72-times more than conventional batteries. Guess we'll get back to watching the Orbo progress.

Unless you're one of the few, the proud who not only can manage to find a seat on an airplane with a power outlet, but can remember your adapter as well, you're probably like us and SOL when it comes to battery powered devices on long flights. That's why we're pretty stoked to see this InFlight USB Power Unit. The concept is pretty simple, but fairly ingenious. You just stick the mini jack of the Power Unit into your seat's headphone port and crank the volume. The device trickle charges for 3-5 minutes, and then can power a connected USB device for a minute, after which the cycle starts all over again. The $35 charger will work with small devices like an iPod, PDA or cellphone, and you can get the Power Gomadic TipExchange Bundle for $50, plus $5 for extra tips, to work with 700 different devices. We'd love to see if this thing can keep up with an iPod's rapid battery depletion, but you know the real reason we want this thing is to power our deco lights for a bit of home-away-from-home on those long flights.
