Happy Birthday Ted Lewis! 4Kids seriously had a great pool of VA's and Ted Lewis is no exception. He has such a great deliciously evil Brit voice for Giovanni and Yami Bakura and he was also excellent as Ryo Bakura, Bandit Keith, Tracey Sketchit, Zangulus, King Dedede, Escargoon and The Ultimate Ninja.
Energy was used during the process. We lost energy as extra heat, friction (created by the turbine), and products of combustion (smoke, carbon dioxide, water). In the end, the natural gas that is combusted is equal to all of the other forms of energy that it was transformed into. Potential and Kinetic Energy. All energy is either potential or kinetic.
Propane is bought and stored in a liquid form (LPG), and thus fuel energy can be stored in a relatively small space. Compressed natural gas (CNG), largely methane, is another gas used as fuel, but it cannot be liquefied by compression at normal temperatures, as these are well above its critical temperature.
