The generator is removably attached to the top panel and is connected to the foot treadles so the generator is operated by actuating the foot treadles. The power generator comprises an electrical connection, such as a USB connector, for a computer or other electrical device. ## Claims ### Claim 1 An apparatus for providing electrical power to a computer or other electrical device, comprising: a manually operable generator for providing electrical power; a desk comprising a top surface portion, side portions and foot treadles pivotally mounted inside said desk portion; connecting means for connecting the foot treadles to the generator; wherein, operation of the foot treadles by the user provides mechanical motion which operates the generator to produce electrical energy. ### Claim 2 (depends on 1) The apparatus of claim 1, wherein said desk is foldable and collapsible for ease of transport. ### Claim 3 (depends on 1) The apparatus of claim 1, wherein said generator is removably mounted to said desk. ### Claim 4 (depends on 1) The apparatus of claim 1, wherein said generator comprises a coil, a magnet internal to said coil, and a wheel comprising an eccentric for creating reciprocal motion, wherein said magnet is connected to said eccentric by means of a connecting rod, and wherein reciprocal movement of the magnet inside the coil generates electricity. ### Claim 5 (depends on 4) The apparatus of claim 4, wherein the connecting means comprises a flexible cord and is connected from the foot treadles to the wheel of the generator such that operation of the foot treadles by the user causes the wheel to rotate. ### Claim 6 (depends on 1) The apparatus of claim 1, further comprising means for electrically connecting the generator to the computer or other electrical device. ### Claim 7 (depends on 1) The apparatus of claim 1, wherein said generator further comprises electrical circuitry to provide the proper electrical voltage to said computer or other electrical device. ### Claim 8 A portable desk having a manually operated generator for providing electrical power to a computer or other electrical device, comprising; a foldable desk comprising a top surface portion, left and right side portions, and a back portion, wherein said top, left and right side portions are foldably attached to said back portion; a left treadle foldably attached to a bottom edge of said left side portion; a right treadle foldably attached to a bottom edge of said right side portion; wherein the foldable desk may be configured to form a box having a top, sides and back, and an open side having the treadles accessible to be manually operated by a user; an electrical power generator removably attached to one of the portions of said foldable desk, said power generator comprising; a coil; a magnet located inside said coil, such that when said magnet is moved reciprocally inside coil, electrical energy is generated; reciprocating means connected to said magnet for creating reciprocal motion of said magnet; an electric circuit connected to said coil for controlling the voltage applied to an output terminal; and means for connecting said left and right treadles to said reciprocating means; whereby, operating said left and right treadles in a up and down motion by said user causes said reciprocating means to move the magnet back and forth inside said coil to generate electrical energy. ### Claim 9 (depends on 8) The portable desk of claim 8, wherein said portions of the desk may be folded together for ease of carrying. ### Claim 10 (depends on 9) The portable desk of claim 9, further comprising a carrying handle at one edge. ### Claim 11 (depends on 8) The portable desk of claim 8, wherein said means for connecting said left and right treadles to said reciprocating means comprises a flexible cord. ### Claim 12 (depends on 8) The portable desk of claim 8, wherein said reciprocating means comprises a wheel mounted on an axis connected to said back portion of the foldable desk, wherein said flexible cord is circumferentially positioned around said wheel such that operation of said left and right treadles creates reciprocating circular motion in said wheel, causing reciprocal motion in said magnet in generating electrical energy. ### Claim 13 (depends on 8) The portable desk of claim 8, wherein said output terminal comprises an electrical connector for connecting said electric circuit to a computer. ### Claim 14 (depends on 13) The portable desk of claim 13, wherein said electrical connector comprises a USB connector.
