Indeed, in some very fun circumstances, there are situations in which systems can work with much more than 100 percent efficiency. There is, for example, this lovely fuel cell with exotic materials that works at more than 100 percent efficiency. It's just that it's only over 100 percent on the side of the cycle that uses the fuel. The side that produces the fuel requires a lot more energy input, and the net of a closed cycle is much less than 100 percent. The 2nd law talks about entropy. This can be related to efficiency, but only in certain conditions. One example is a heat engine working between two different temperature volumes. It cannot be easily related to efficiency in the general case. Thus "no system" is not the correct basis of stating the 2nd law. > that contradicts the conservation laws. The 2nd law most certainly does not contradict conservation laws. Energy, for example, is conserved in thermodynamics. > when the 2nd law of TD is on duty you cannot apply the conservation > laws. You do not seem to understand this at all. The 2nd law is *always* true. If it contradicted conservation laws, there would be none. Socks
