The biggest difference between the Sabbath and this "Do Nothing" challenge is that you eat on the Sabbath. Traditionally three Sabbath meals are in fact required, though you can't do the labor to prepare them or use energy to heat them. It is odd that the OP and every comment thus far on HN skip over that aspect. As OP describes it this is also a fast.
