As&#160;One Laptop Per Child prepares to ship its highly anticipated XO laptops in two weeks, it is developing a &quot;supercharger,&quot; a mass battery recharger that will draw power from cows and yo-yos to help the laptops run longer.The supercharger is a box that will charge 15 batteries at a time, said Mary Lou Jepsen, chief technology officer for OLPC.The supercharger complements other environmentally friendly battery charging technologies being used or under development for the XO laptop, Jepsen said. Users can hook up handcranks, cows, yo-yos, foot pedals and solar panels to the box to recharge batteries.Last week OLPC said it was designing a cow-powered generator through a dynamo with a system of belts and pulleys using cattle to generate power.A typical charge cycle for a laptop battery should be about three hours, Jepsen said. Groups of children will be able to share batteries.Currently in design, the supercharger will be ready for manufacturing next year, Jepsen said.A laptop&#39;s mileage depends on its usage, so OLPC designed an environmentally friendly laptop that could work with a rugged, low-power battery, Jepsen said. The laptop&#39;s specially designed lithium-ferro phosphate battery consumes between 2 watts to 8 watts depending on usage, Jepsen said. It lasts five years and works in environments up to 100 degrees Fahrenheit (37 degrees Celsius), Jepsen said.The XO batteries do not work on normal laptops, which can sap up to 40 watts of power depending on usage, Jepsen said.The XO is also the first laptop that uses only alternative energy, Jepsen said. Low-cost solar panels are great as a power option where there is plenty of sunlight, Jepsen said. Energy is especially scare in developing nations, so the laptop will hopefully pass on energy preservation lessons, which could help preserve battery life in the XO, Jepsen said.The laptop goes into manufacturing this week after three years of design experimentation and attempts to reduce manufacturing cost. It will first be offered in two weeks to consumers in the Give 1 Get 1 program, in which two laptops can be purchased for about US$400, with a user getting one laptop and the other being donated.&quot;We&#39;re exhausted, but exhilarated,&quot; Jepsen said.REFERENCES:OLPC experiments with cow-powered laptops ... seriously, Oct. 24, 2007

This little OQO  machine is certainly pretty cool.  The biggest problem though is that it doesn't run Linux.  This leaves you with a device heavier than your PDA and all the insecurity and bloat of Windows and with a price tag of only sub $2000.  People don't care what OS their PDA/Handtop runs.  It can run an alternative OS and for the most part consumers don't care.  WinCE hasn't exactly been a stellar market success.  While Microsoft does have significant market share PalmOS, Symbian, and Linux are doing just fine.  Also most of the WinCE devices never have the fit and finish of their Palm and Symbian counterparts.  I don't know where OQO thinks they are going to fit in.  If they were to  ...

(InfoWorld) - Samsung Electronics will introduce an upgraded version of its Q1 ultra-mobile PC with extended battery life, high-speed cellular, and a new processor. The Q1P, a successor to the Q1, will extend battery life to five hours and connect to cellular networks based on HSDPA (High Speed Downlink Packet Access), Gee Sung Choi, president and chief executive of Samsung Digital Media Business, said Friday at the IFA consumer electronics show in Berlin. The device, to be available in the fourth quarter, will also be equipped with a processor from Via Technologies instead of Intel, which supplied technology for the first model, a company spokesman said. The spokesman declined to specify the reasons for replacing Intel, pointing only to a need to extend battery life. The Q1P will include several additional interfaces, but the spokesman declined to provide details. Pricing information was not available. The Q1 device, launched earlier this year, runs a tablet version of the Windows XP operating system and is intended to fit in the market between laptop PCs and PDAs (personal digital assistants). The new version takes advantage of HSDPA, which mobile phone network operators are rolling out with initial speeds up to 1.8Mbps. The technology is engineered for peak speeds of 14.4Mbps. Samsung's ultra-mobile PC already offers Wi-Fi connectivity.

Imagine running your laptop nonstop from New York to Tokyo -- crunch some numbers, work on a memo pop in a few DVDs -- and then do a full day of meetings, using your machine throughout the day and into the night. Imagine doing all of this without ever plugging in your computer to recharge its battery.
