Your independent source for news, information, commentary, and discussion of One Laptop Per Child's "$100 laptop" computer, the OLPC Children's Machine XO, developed by MIT Media Lab co-founder Nicholas Negroponte.
Freeplay claims that cranking the spur gear transmission driving a 3-phase alternator with 3-phase rectification at 130-140 rpm will yield a nominal 15VDC 1500mA output. In addition, it can be cranked in either direction. Quite an achievement, eh?

I read somewhere that one minute of cranking would enable the laptops to run for 10 minutes. Great to see hand cranked power extending its horizons.
