It doesn't move like a human. It has digitigrade legs and a forward-backwards horizontal balance thing. It runs, I guess, like a raptor. It's not a big shock

It's not a big shock that things built for speed can run faster than humans can. Horses can also run faster than humans. So can cheetahs. Ostriches, if you want something bipedal.
- throwaway7767 12y agoExactly. It also can't move in any of the other ways a human can, it certainly won't be climbing obstacles. It's not as if humans are the pinnacle of power efficiency. We're versatile, but inefficient. So if you're going to compare a machine to human movement, it should be on the basis of versatility. A car is way more efficient than a human at moving on a flat track.
- maxerickson 12y agoA human uses less energy going a mile on foot than a car does. So for one definition of efficient, the human wins. They should still win even if they are carrying a modest load. I guess I would have used effective where you said efficient. (If you add in the energy used by modern agriculture to produce the food the human ate, the car probably wins: http://ideas.4brad.com/holy-cow-walking-consumes-more-gasoline-driving http://ideas.4brad.com/holy-cow-walking-consumes-more-gasoli...)
- rquantz 12y agoHow much energy does a human use when he carries a car for a mile?
- maxerickson 12y agoI'm curious how I could have better phrased my comment so as to not invite responses like this. I guess I realize that 'efficient' vs 'effective' is a quibble, but I was trying to respond to the ambiguous usage of 'efficiency', not trying to give the final answer on the comparison.
- rquantz 12y agoSorry, I realized you were trying to be circumspect, I just was instantly visited with a vision of a guy trudging around a track with a car on his back.
- ori_b 12y agoHow much of that comes from bipedal motion, vs the way that humans break down their food?
