Atmospheric concentrations of the most ubiquitous greenhouse gas reached 381 parts - per - million in 2006 after emissions of CO2 from burning fossil fuels rose to 8.4 billion metric tons (1.85 x 1013 pounds) per year, according to figures from the United Nations, British Petroleum and the U.S. Geological Survey.
Though the diesel's EPA figure of 23 mpg combined beats the gas model's 18 mpg average, its torque is mostly available at lower rpms, petering out by the time the engine reaches its most crucial point in the powerband.
So asserting that heat won't flow in figure 2 above, or will stop flowing before all of the gas reaches thermal equilibrium, is just like saying that heat won't flow between two ordinary jars of gas at different temperatures in the laboratory, and well over a hundred years of experiments, the entire refrigeration and air conditioning industry, a huge body of technology and engineering, and well understood physical theories all say otherwise.
The device in figure 2 doesn't work because it's a closed system and the work extracted will reduce the total energy of the column until eventually there's no more energy to extract at which point the gas reaches a temperature of absolute zero and has presumably vanished from this universe being totally converted to kinetic energy in the extracted useful work.
One is then left with an uncomfortable picture of the gas moving constantly — heat must be adiabatically convected downward to the bottom of the container in figure 1 in ongoing opposition to the upward directed flow of heat due to the fact that Fourier's Law applies to the ideal gas in such a way that equilibrium is never reached!
They reach # 78 / tonne in 2030 and would be enough to push the costs of gas - fired generation up above the level of mature low - carbon options in the 2020s (Figure 2).
