1. A system for generating electrical energy, comprising:

  • a micro-combustor having a fuel inlet, an exhaust outlet, a combustion chamber and an igniter operative to initiate combustion of fuel within said combustion chamber which produces hot exhaust gas directed to said exhaust outlet;

    a micro-controller coupled to said igniter of said micro-combustor;

    a fluid control device which supplies fuel from a source to said micro-combustor, said fluid control device being coupled to said micro-controller which controls opening and closing of said fluid control device;

    a thermoelectric module having a first end mounted in thermal communication with said micro-combustor, and a second end spaced from said first end, a temperature differential being produced between said first and second ends of said thermoelectric module which induces said thermoelectric module to generate a first supply of electrical energy; and

    a micro-turbine communicating with said exhaust outlet of said micro-combustor to receive said hot exhaust gas, said micro-turbine being effective to generate a second supply of electrical energy.
