(With reference to the the green hand crank)
On the page http://wiki.laptop.org/go/Product_News
there is a link to the Freeplay Hand crank spec sheet
Page 1 of the spec sheet (under the section of Benefits) mentions that the Crank can work upto 500,000 revolutions.
Cranking at the rated rpm(130rom), it means that it can do 500000/130 = 3846 minutes = 64 hours.
One session of cranking takes about 3 hours, which means that the laptop can only be charged 64/3 = 21 times.
