         21 . A method for cooking, the method comprising:
 providing a refillable gas container comprising at least one of aluminum, aluminum alloy, titanium, titanium alloy, nickel, nickel alloy and stainless steel and containing a hydrogen-methane gaseous mixture comprising hydrogen gas in an amount in a range of 30 to 95 volume percent of the gaseous mixture and methane gas in an amount in a range of 5 to 70 volume percent of the gas mixture;   providing a cookable material;   discharging the hydrogen-methane gaseous mixture from the gas container;   combusting the hydrogen-methane gaseous mixture with oxygen to create heat; and   applying the heat to the cookable material.   
     
     
         22 . There method of  claim 21 , wherein the refillable gas container comprises a gas cylinder. 
     
     
         23 . The method of  claim 21 , wherein the gas container does not contain a solid filler material. 
     
     
         24 . The method of  claim 21 , wherein the step of using the heat source comprises using the heat source as at least one of a stove or grill. 
     
     
         25 . The method of  claim 21 , further comprising providing a source of oxygen for the combustion with the hydrogen-methane gaseous mixture, wherein the source comprises at least one of ambient air, compressed air, or compressed oxygen. 
     
     
         26 . The method of  claim 21 , wherein the combusting step provides a flame that has minimal or is free of soot. 
     
     
         27 . The method of  claim 21 , wherein the hydrogen gaseous mixture comprises hydrogen gas in an amount in a range of 85 to 95 volume percent of the gaseous mixture and methane gas in an amount in a range of 5 to 15 volume percent of the gaseous mixture. 
     
     
         28 . The method of  claim 21 , wherein the hydrogen gaseous mixture comprises hydrogen gas in an amount in a range of 93 to 95 volume percent of the gaseous mixture and methane gas in an amount in a range of 5 to 7 volume percent of the gaseous mixture. 
     
     
         29 . The method of  claim 21 , wherein the gaseous mixture comprises no more than 1000 parts per million of carbon monoxide. 
     
     
         30 . The method of  claim 21 , wherein the gaseous mixture comprises no more than 1000 parts per million of carbon dioxide. 
     
     
         31 . A method for cutting, brazing, soldering or heating a metal, the method comprising:
 providing a refillable gas container comprising at least one of aluminum, aluminum alloy, titanium, titanium alloy, nickel, nickel alloy and stainless steel and containing a hydrogen-methane gaseous mixture comprising hydrogen gas in an amount in a range of 30 to 95 volume percent of the gaseous mixture and methane gas in an amount in a range of 5 to 70 volume percent of the gas mixture;   providing a metal to be cut, brazed, soldered or heated;   discharging the hydrogen-methane gaseous mixture from the gas container; and   combusting the hydrogen-methane gaseous mixture with oxygen to create heat.   
     
     
         32 . There method of  claim 31 , wherein the refillable gas container comprises a gas cylinder. 
     
     
         33 . The method of  claim 31 , wherein the gas container does not contain a solid filler material. 
     
     
         34 . The method of  claim 31 , wherein the step of using the heat source comprises using the heat source as a torch. 
     
     
         35 . The method of  claim 31 , further comprising the step of providing a source of oxygen for the combustion with the hydrogen-methane mixture, wherein the source comprises at least one of ambient air, compressed air, or compressed oxygen. 
     
     
         36 . The method of  claim 31 , wherein the combusting step provides a flame that has minimal or is free of soot. 
     
     
         37 . The method of  claim 31 , wherein the gaseous mixture comprises hydrogen gas in an amount in a range of 85 to 95 volume percent of the gaseous mixture and methane gas in an amount in a range of 5 to 15 volume percent of the gaseous mixture. 
     
     
         38 . The method of  claim 31 , wherein the hydrogen gaseous mixture comprises hydrogen gas in an amount in a range of 93 to 95 volume percent of the gaseous mixture and methane gas in an amount in a range of 5 to 7 volume percent of the gaseous mixture. 
     
     
         39 . The method of  claim 31 , wherein the gaseous mixture comprises no more than 1000 parts per million of carbon monoxide. 
     
     
         40 . The method of  claim 31 , wherein the gaseous mixture comprises no more than 1000 parts per million of carbon dioxide.
