An energy generating system for a telecommunications facility includes a hydrogen fuel supply system. The hydrogen fuel supply system includes a source of liquid hydrogen which uses a high pressure expansion tank along with additional storage tanks. The system also incorporates first and second stage heat exchangers. The first stage exchanger is used to benefit from the endothermic reaction created when liquid hydrogen transforms into vapor. The cooling provided from this state change is transferred into a second medium which is delivered into a second stage heat transfer device and then used for air conditioning purposes. The system also includes a hydrogen generator which may be used to create AC power by combusting vaporous hydrogen.

The method of claim 22, comprising: absorbing heat into at least one of said liquid and vaporous hydrogen from a heat transfer medium; and using said heat transfer medium for cooling purposes. 28. The method of claim 27, comprising: selecting a fluid to serve as the heat transfer medium. 29. The method of claim 27, comprising: selecting ethylene glycol to comprise a part of said heat transfer medium. 30. The method of claim 27, comprising: receiving said heat transfer medium after said heat has been absorbed out of it; and cooling with said heat transfer medium. 31. The method of claim 30, comprising: air conditioning a portion of said facility using cooling provided by said heat transfer medium. 32. The method of claim 22, comprising: including said conduit in a housing; ventilating said housing; and transmitting said heated air in and out of said housing. 33. The method of claim 22, comprising: drawing heat energy from a power-generating device in creating said heated air. 34. The method of claim 22, comprising: drawing heat energy from an internal combustion engine in creating said heated air. 35. The method of claim 22, comprising: drawing heat energy from the same device used to accomplish said generating step in creating said heated air. 36. The method of claim 22, comprising: deriving a heat-delivering medium from a power-generating device in creating said heated air. 37. The method of claim 36, comprising: selecting as said heat-delivering medium a fluid used to cool said power-generating device. 38. The method of claim 37, comprising: pumping said heat-delivering medium from an engine jacket on said power-generating device in creating said heated air; and returning said heat-delivering medium to said engine jacket after it has been used in creating said heated air.
