OLPC experiments with cow-powered generator for laptops

Now cow fodder will be expensive , i wonder what it will be to cost to mail you guys through a laptop if any body could afford one, we will be charged on the basis of cow hours instead of watts or likes , they mention solar , wind , water power unfeasable , this is disgusting ,really frustrating , you did not mention humans that are also plentifull far outnumbering cows , can`t you guys employ humans for the same and leave cows for milk supply there humans cannot supply

Um, I don't think they are planning on converting the cows into laptop food, just make them walk around in circle (presumably). And the laptops come with a crank, so the human is the planned power of last resort... and what human wouldn't take the initiative and hook up his dog/cow/goat/whatever if he could figure out how to do it. The cost/benefit is there for people to figure out all for themselves.

FYI, they are projects that use humans for power... I read here somewhere about a children's playground that pumps water into a large storage tank as they play on a big spinning carousel-type thing.
