One famous limit of thermodynamics is that heat engines, like steam engines and internal combustion engines, must be less efficient than a Carnot heat engine (a heat engine cycle designed by French ...

One of the basic truths learned in college thermodynamics courses is that no heat-activated cycle can be devised that is more efficient than a Carnot cycle operating between the same temperature ...

Nelson Ireson June 6, 2008 Comment Now! Novel technologies to improve the efficiency of existing vehicles and combustion processes are the quickest route to improved fuel mileage. Hybrid cars are ...

The key to understanding the proposed LNG revaporization processes that follow is that the temperature difference between the heat source (a→a’) and the heat sink supplied by the liquid methane (1→4) ...

Breakthroughs, discoveries, and DIY tips sent six days a week. Terms of Service and Privacy Policy. Split cycle engines—engines that split the functions of a normal ...

Steam engines run because of statistics — the particles in the machine have a predictable overall behavior, which drives the engine’s piston up and down. But if you shrink the engine down to ...
