Fuel plasma vortex combustion system

A combustion system comprising:

• a combustion chamber having a fuel inlet;
• a preheating chamber surrounding the combustion chamber having an air inlet for tangentially feeding combustion air to the preheating chamber, the combustion chamber having an elongate slot for admitting preheated air in circulating motion to said combustion chamber, a plasma chamber coupled to said combustion chamber, and having an inlet aperture for receiving combusting fuel-air plasma from said combustion chamber, and an outlet aperture for expelling combusted gas, said plasma chamber having an inverted end wall surrounding said outlet aperture operative for forming an imploding vortex in said plasma chamber, wherein said plasma chamber has an internal wall of substantially spherical shape, and a center;
• including a central sphere in said plasma chamber for generating standing waves in said plasma chamber, said central sphere having an inner cavity, a sonic tube fluidly connecting said cavity with said combustion chamber, said sonic tube operative for transmitting sonic waves from said cavity to said combustion chamber.
