Patent ID: 7302795

Claim:
An internal combustion engine (ICE)/water source system comprising: (a) an ICE assembly including an ICE and an exhaust duct for flowing exhaust gases from said ICE; and, (b) a water source assembly for providing liquid water, said water source assembly comprising: (i) a compressor fluidly connected to said exhaust duct, said compressor adapted for receiving exhaust gases from said exhaust duct and compressing them to a predetermined pressure value, said predetermined pressure value being substantially greater than the pressure inside said exhaust duct; (ii) a condenser fluidly connected to said compressor, said condenser adapted for receiving compressed gases from said compressor and cooling them to below a dew point to induce condensation of liquid water therefrom; (iii) a reservoir fluidly connected to said condenser and adapted for receiving and collecting liquid water therefrom; (iv) a backpressure device fluidly connected to said reservoir and adapted for releasing excess compressed gases; and wherein said ICE assembly further includes a coolant system having a flow of liquid coolant maintained by a thermostatic valve at a temperature between about 10 degrees Centigrade and about 50 degrees Centigrade; and at least one of said compressor, said condenser and said reservoir is in a good thermal communication with said flow of liquid coolant.
