A strange compressor at constant volume:
"A device has been presented which uses the thermal energy
of a hot source. At constant volume, it allows the molecule
concentration of a gaseous fluid to increase without spending
mechanical energy. It can produce a significant temperature
increase above the temperature of the hot source which is
heating it. It could be profitable to use this process to convert
the thermal energy of a hot source into work."
Strange, isn't it ?

(this paper was rejected: it was not published during the International Conference on renewable energy utilization. The reason is because this other one was accepted:
http://www.monotherme.com/pdf/research_ ... t_pump.pdf and one paper relative to the same concept was enough).
