• at least one combustion chamber;
• at least one compressor constructed and arranged to provide a compressed gas to said at least one combustion chamber;
• and
• at least one turbine blade constructed and arranged to be driven by a pressurized gas formed in said combustion chamber;
• wherein said combustion chamber comprises:
• a wall structure defining an interior chamber;
• a first reflecting surface for reflecting a pressure wave within said interior chamber;
• a second reflecting surface for reflecting said pressure wave within said interior chamber, wherein said first and second reflecting surfaces being constructed and arranged to resonate said pressure wave in said interior chamber;
• at least one first inlet for introducing a first gas into said interior chamber, said first inlet being located where the pressure in said combustion chamber varies, and said first inlet comprising a first inlet valve for controlling the flow of said first gas into said interior chamber, said first inlet valve being constructed and arranged to open and close in sync with said resonating pressure wave whereby said first inlet valve is open when lower than average interior chamber pressures are prevalent against said first inlet valve and closed when higher than average interior chamber pressures are prevalent against said first inlet valve;
• at least one second inlet for introducing said compressed gas into said interior chamber being located where a pressure varies in said combustion chamber, and said second inlet comprising a second inlet valve for controlling the flow of said second gas into said interior chamber, said second inlet valve being constructed and arranged to open and close in sync with said resonating pressure wave whereby said second inlet valve is open when lower than average interior chamber pressures are prevalent against said second inlet valve and closed when higher than average interior chamber pressures are prevalent against said second inlet valve, said second inlet being connected to said at least one compressor;
• and
• at least one outlet from said interior chamber for drawing off said pressurized gas from said chamber and being constructed and arranged to supply said pressurized gas to said at least one turbine blade, wherein said first inlet valve and said second inlet valve comprise a rotary valve.

A method of forming a pressurized gas having a temperature lower than a combustion temperature of a combustible gas used to form said pressurized gas comprising the steps of:

• introducing a combustible gas into a combustion chamber having first and second reflecting surfaces that are constructed and arranged to provide a resonating pressure wave reflecting between said first and second reflecting surfaces, said combustible gas being introduced into said combustible chamber at a frequency such that said resonating pressure wave ignites said combustible gas to thereby form a resonating pressure wave;
• introducing a second gas into said combustion chamber at a location and frequency such that said pressure wave compresses and combines with said second gas to form a pressurized gas having a temperature lower than a combustion temperature of said combustible gas;
• and
• withdrawing said pressurized gas from said combustion chamber, wherein said first and second gases are introduced into said combustion chamber through a rotary valve.
