         4 . The heat generator as set forth in  claim 2 , wherein:
 the heating element is comprised of a first and a second heating elements.   
     
     
         5 . The heat generator as set forth in  claim 4 , wherein:
 the first enclosures include a first eccentric opening for receiving a connecting end of the first heating element;   the second enclosures include a second eccentric opening for receiving a connecting end of the second heating element.   
     
     
         6 . The heat generator as set forth in  claim 5 , wherein:
 the first eccentric opening of the first enclosure at the first distal end of the heater chamber is non-aligned with the second eccentric opening of the second enclosure at the second distal end of the heater chamber;   wherein: the non-aligned first eccentric opening and the second eccentric opening enable the first heating element and the second heating element with elongated structures to have overlapping spanning lengths within the heater chamber.   
     
     
         7 . The heat generator as set forth in  claim 1 , wherein:
 the heater chamber is comprised of a plurality of heater chambers, with a first heater chamber connected to a next heater chamber by a connecting chamber.   
     
     
         8 . The heat generator as set forth in  claim 1 , wherein:
 the mechanism is comprised of:   motor pump and filter.   
     
     
         9 . The heat generator as set forth in  claim 1 , wherein:
 heated heat delivery medium is move to an external device for heating the external device and is returned to the expansion tank as cooled-OFF heat delivery medium.   
     
     
         10 . A heating device, comprising:
 a heat chamber;   a heat distribution system for delivery, distribution, and collection of a heat delivery medium to and from the heat chamber;   an air circulation system for circulating ambient air through the heat chamber; and   a mixer-aeration system for conveyance of waste;   wherein: the waste is dried within the heat chamber as a result of application of heat by the heat delivery medium and movement of waste due to mixer-aeration system;   wherein: bacterial levels of the waste are reduced as a result of generation of electrostatic discharge within the heat chamber due to differences in a moisture content of the waste inside the heat chamber and outside ambient air circulated into the heat chamber by the air circulation system as waste is moved and mixed and aerated by the mixer-aeration system.   
     
     
         11 . The heating device as set forth in  claim 10 , wherein:
 the heat chamber includes:   an ingress opening for receiving waste;   an egress opening for removal of waste;   a passive enclosure that opens and closes the ingress opening based on a level of the waste accumulated with the heat chamber.   
     
     
         12 . The heating device as set forth in  claim 10 , wherein:
 the heat distribution system includes a heat distribution compartment position adjacent the heat chamber;   wherein: the heat delivery medium is moved through the heat distribution compartment, supplying heat to an interior of the heat chamber by conduction and convection.   
     
     
         13 . The heating device as set forth in  claim 10 , wherein:
 the air circulation system includes:   an intake vent opening through which ambient air is pulled into the heat chamber; and   an evacuation opening through which air within the heat chamber is removed.   
     
     
         14 . The heating device as set forth in  claim 10 , wherein:
 the mixer-aeration system, includes:   a drive mechanism that moves a mixer-aeration mechanism to mix and aerate waste.   
     
     
         15 . A heating device, comprising:
 a heat chamber that is comprised of a double walled cylindrical hollow body through which waste is moved by an auger;   a heat distribution system for delivery, distribution, and collection of a heat delivery medium to and from the heat chamber; and   air removal system for removal of moisture from within the heat chamber;   wherein: the waste is dried within the heat chamber as a result of application of heat by the heat delivery medium.   
     
     
         16 . The heating device as set forth in  claim 15 , wherein:
 the double walled cylindrical hollow body of the heat chamber forms a compartment through which heated heat delivery medium is circulated, supplying heat to an interior of heat chamber by conduction and convection.   
     
     
         17 . The heating device as set forth in  claim 15 , wherein:
 the auger is a hammer auger.
