Glushko eugene.glushko@scientist.com 1 Institute of Semiconductor Physics of the NAS of Ukraine, Nauki Ave, Kiev, Ukraine In this paper, the problem of increasing the energy capacity of compressed air used as a mobile carrier of energy is considered. An idea of preliminary Joule-Thomson self-heating of the compressed air with the following heat redistribution to obtain the maximal work at maximal power is considered. A simple circle combination of a heat exchanger and a throttle device-Linde-Hampson anti-machine - is analyzed. Calculations performed in the framework of modified van der Waals gas model show essential increasing of accumulated specific energy of compressed air fuel to the range 0.5-1.0 MJ/kg which is comparable with electrochemical fuel energy. A concept of compressed air fuel production is discussed. http://pubs.sciepub.com/ajer/1/3/4/ajer-1-3-4.pdf compressed air energy capacity Joule-Thomson process heat exchanger pneumatic vehicles pollution free fuel
