At 5% efficiency for humans, food to movement, a bigmac (no cheese) is about 8 energizer alkaline batteries.

Don't ask me who eats their bigmacs without cheese, I have no idea.]]>Dec 15th 2006 4:41PMhttp://www.engadget.com/2006/12/15/olpcs-pull-string-power-system-going-commercial/http://www.engadget.com/2006/12/15/olpcs-pull-string-power-system-going-commercial/Dec 15th 2006 9:45PMhttp://www.engadget.com/2006/12/15/olpcs-pull-string-power-system-going-commercial/http://www.engadget.com/2006/12/15/olpcs-pull-string-power-system-going-commercial/Dec 15th 2006 4:26PMhttp://www.engadget.com/2006/12/15/olpcs-pull-string-power-system-going-commercial/http://www.engadget.com/2006/12/15/olpcs-pull-string-power-system-going-commercial/Dec 15th 2006 4:36PMhttp://www.engadget.com/2006/12/15/olpcs-pull-string-power-system-going-commercial/http://www.engadget.com/2006/12/15/olpcs-pull-string-power-system-going-commercial/Dec 15th 2006 7:37PMhttp://www.engadget.com/2006/12/15/olpcs-pull-string-power-system-going-commercial/http://www.engadget.com/2006/12/15/olpcs-pull-string-power-system-going-commercial/
Now, some people may not need to drop the cals- starving shouldn't use this. But if you eat 4 cheeseburgers, that's gonna be probably enough to keep you going and charge a laptop a couple times.]]>Dec 15th 2006 9:47PMhttp://www.engadget.com/2006/12/15/olpcs-pull-string-power-system-going-commercial/http://www.engadget.com/2006/12/15/olpcs-pull-string-power-system-going-commercial/Dec 16th 2006 8:03AMhttp://www.engadget.com/2006/12/15/olpcs-pull-string-power-system-going-commercial/http://www.engadget.com/2006/12/15/olpcs-pull-string-power-system-going-commercial/Dec 16th 2006 9:47AMhttp://www.engadget.com/2006/12/15/olpcs-pull-string-power-system-going-commercial/http://www.engadget.com/2006/12/15/olpcs-pull-string-power-system-going-commercial/Dec 16th 2006 3:21PMhttp://www.engadget.com/2006/12/15/olpcs-pull-string-power-system-going-commercial/http://www.engadget.com/2006/12/15/olpcs-pull-string-power-system-going-commercial/James wrote on Dec. 15, 2006 . . .

"The one thing that would kill this project dead quicker than any other design error would be to use a proprietary plug. Who's with me?"


Hi James . . .

Yes, this would be a deal killer. But the question remains as to what connector they ARE using. I've emailed Quanta (manufacturers of the XO) and Potenco (makers of the power supply) as well as numerous others associated with the OLPC project. It's apparent that it's an off-the-shelf barrel connector of some sort (judging by various photos) but nobody seems to know (or, for some strange reason, wants to tell anybody) what particular size connector they are using and which way they have it polarized.
