second embodiment
[0036]FIG. 3 shows the invention that maximizes the heat differential within the thermocouple 78. Waste heat reclamation device 70 thereof includes a thermocouple 78 and a conditioning unit 100. Thermocouple 78 has a first conductor 80 and a second conductor 82 joined by junction 77. As with the embodiment of FIG. 2, junction 77 is bound to heat sink 74 by a thermally conductive but electrically insulating layer 76. Heat sink 74 is thermally conductively attached to waste heat generating component 72. Leads 84 and 90 connect thermocouple 78 to conducting wires 94 and 96 to conduct a current to conditioning unit 100. The current so supplied to conditioning unit 100 by thermocouple 78, through conducting wires 96 and 94, is conditioned to provide a constant current to outputs lines 104 and 106. Power Lines 98 and 102 provide additional power to conditioning unit 100 as needed to convert the varying current supply by thermocouple 78 into a more stable, steady current.

third embodiment
[0039]FIG. 4 shows a third embodiment in the form of a typical conduction unit 120 for use in the invention. Conduction unit 120 is comprised of a diode OR 122. A suitable such diode is made by Linear Technology Corp and sold as chip LTC 4412. A power supply is fed into input 136 of diode OR 122 through conducting wires 126 and 124. Diode OR 122 is also connected to a thermocouple waste heat reclamation device by means of conducting wires 128 and 130 at input 138. Diode OR 122 supplies a constant, steady current to wires 132 and 134 at output 140 so long as current is provided at least from the power source feeding input 136. As current is fed into diode OR 122 through input 138, the amount of current the diode OR 122 accepts through input 136 decreases accordingly. The current provided through output 140 is always equal to the sum of the inputs received from inputs 136 and 138. In this fashion, conditioning unit 120 maintains a constant and stable output current strength.
fourth embodiment
[0040]FIG. 5 shows a waste heat harnessing device 150 of the present invention. In this embodiment, waste heat harnessing device 152 is a thermocouple device having a series of thermocouples within it. This is a relatively common configuration for thermocouple devices. It is well know in the art to combine two or more thermocouples into a series of many thermocouples in much the same way the electric batteries are placed in series. Heat harnessing device 152 is attached by means of thermally conductive electrically insulating layer 174 to heat sink 166 which is attached to waste heat generating device 164. Heat sink 166 is also attached in a thermally conductive way to heat dissipating device 168 having a plurality of fins 170. There exist many heat sinks which themselves have a series of fins extending outwardly from them instead of a separate heat dissipating device attached to it. Fan 172 in this embodiment aids in the dissipating of heat through fins 170 and also helps to mainta...
