An air heater is provided for use in buildings or other structures. The air heater uses infrared lamps to generate a temperature rise in a forced air chamber that contains several infrared lamps, in which two ends of the chamber act as an inlet and an outlet, and in which the chamber has a highly reflective interior surface that reflects the light being emitted by the lamps to multiply the thermal effect of the infrared light sources. An alternative embodiment uses a closed chamber, in which the temperature rise causes the unit to act as a detonator.

The invention claimed is: 1. A detonator apparatus, comprising: an enclosure that substantially encompasses a volume of gas, said enclosure having an inner surface and an outer surface, at least a major portion of said inner surface being highly reflective, said enclosure being substantially gas-tight; a layer of explosive material that is positioned along at least a portion of the outer surface of said enclosure; an elongated member that is positioned substantially within said volume; at least one light source mounted to said elongated member, said at least one light source being powered by electricity, said at least one light source being positioned so that, when energized, it emits radiant energy that is directed substantially toward said highly reflective portion of the inner surface of said enclosure; wherein: (a) when energized, said at least one light source emits radiant energy, much of which is reflected by said highly reflective portion of the inner surface of said enclosure, which thereby increases an effect of raising a temperature of said gas within the volume; (b) as the temperature of said gas is raised, a temperature of said enclosure is raised; (c) as the temperature of said enclosure is raised, a temperature of said layer of explosive material is raised; and (d) when said layer of explosive material reaches a predetermined ignition temperature, it detonates. 2. The detonator apparatus as recited in claim 1, wherein said enclosure comprises thermally-conductive material, and said enclosure is raised in temperature in a substantially uniform manner, such that substantially all portions of said enclosure achieve substantially a same higher temperature at substantially the same moment, and thereby increases a uniformity of the detonation. 3. The detonator apparatus as recited in claim 1, further comprising an outer housing that is positioned around at least a substantial portion of the layer of explosive material. 4. The detonator apparatus as recited in claim 1, wherein said gas is pressurized above one atmosphere. 5. The detonator apparatus as recited in claim 1, wherein said at least one light source comprises a plurality of light sources that are spaced apart in a linear direction along a longitudinal axis of said elongated member. 6. The detonator apparatus as recited in claim 1, wherein said at least one light source comprises a plurality of light sources that are positioned in a radial direction with respect to a longitudinal axis of said elongated member. 7. The detonator apparatus as recited in claim 6, wherein said plurality of light sources are spaced apart from one another in a radial direction at a single position along said longitudinal axis of the elongated member. 8. The detonator apparatus as recited in claim 7, wherein said plurality of light sources are grouped in a plurality of banks, and each bank of the plurality of light sources is spaced apart from the other said banks in a linear direction along said longitudinal axis of the elongated member. 9. A detonator apparatus, comprising: an enclosure that substantially encompasses a volume of gas, said enclosure having an inner surface and an outer surface, at least a major portion of said inner surface being highly reflective, said enclosure being substantially gas-tight; a layer of explosive material that is positioned within said enclosure; an elongated member that is positioned substantially within said volume; a plurality of light sources mounted to said elongated member, said plurality of light sources being positioned so that they emit radiant energy substantially toward said inner surface of the enclosure and extend radially from said elongated member, said plurality of light sources being spaced-apart from one another in which a spacing between said plurality of light sources and said inner surface of the enclosure allows much of the radiant energy to be reflected by said inner surface in a direction that does not directly intersect the plurality of light sources which, when said plurality of light sources are energized, thereby increases an effect of raising a temperature of said gas within the volume; wherein: (a) when said plurality of light sources emit radiant energy, a temperature of said gas is raised; (b) as the temperature of said gas is raised, a temperature of said enclosure is raised; (c) as the temperature of said enclosure is raised, a temperature of said layer of explosive material is raised; and (d) when said layer of explosive material reaches a predetermined ignition temperature, it detonates. 10. The detonator apparatus as recited in claim 9, wherein said enclosure comprises thermally-conductive material, and said enclosure is raised in temperature in a substantially uniform manner, such that substantially all portions of said enclosure achieve substantially a same higher temperature at substantially the same moment, and thereby increases a uniformity of the detonation. 11. The detonator apparatus as recited in claim 9, further comprising an outer housing that is positioned around at least a substantial portion of the layer of explosive material. 12. The detonator apparatus as recited in claim 9, wherein said gas is pressurized above one atmosphere. 13. A method for heating a detonator apparatus, said method comprising: providing a heating chamber having an enclosure that substantially encompasses a volume of gas, said enclosure having an inner surface and an outer surface, at least a major portion of said inner surface being highly reflective, said enclosure being substantially gas-tight; providing a layer of explosive material that is positioned within said enclosure; providing an elongated member substantially within said volume; providing a plurality of light sources that are mounted to said elongated member; emitting radiant energy from said plurality of light sources toward at least a portion of said highly reflective interior surface of the enclosure member; reflecting, at said highly reflective interior surface of the enclosure member, much of said radiant energy in a direction that does not directly intersect said plurality of light sources, thereby increasing an effect of raising a temperature of said gas within the volume; raising a temperature of said enclosure, as the temperature of said gas is raised; raising a temperature of said layer of explosive material, as the temperature of said enclosure is raised; and detonating said layer of explosive material when it reaches a predetermined ignition temperature. 14. The method as recited in claim 13, wherein said plurality of light sources extend radially from said elongated member. 15. The method as recited in claim 14, wherein said plurality of light sources are spaced apart in a linear direction along a longitudinal axis of said elongated member. 16. The method as recited in claim 15, wherein said plurality of light sources are grouped in a plurality of banks, each of said banks having a plurality of said light sources that are spaced apart from one another in a radial direction at a single position along said longitudinal axis of the elongated member, and each of said banks of the plurality of light sources being spaced apart from the other said banks in said linear direction. 17. The method as recited in claim 13, wherein said enclosure has a cylindrical form, and said elongated member is positioned substantially along a centerline of said enclosure. 18.
