1. An apparatus comprising: a cathode;an anode, wherein the anode and cathode are receptive to a first power source to produce an anode electric potential higher than a cathode electric potential;a gate positioned between the anode and the cathode, the gate being receptive to a second power source to produce a gate electric potential selected to induce electron emission from the cathode;a suppressor positioned between the gate and the anode, the suppressor being receptive to a third power source to produce a suppressor electric potential selected to provide a force on an electron in a direction pointing towards the suppressor in a region between the suppressor and the anode; and wherein at least one of the gate and suppressor is responsive to a current to vary at least one of the gate and suppressor electric potentials. 2. The apparatus of claim 1 wherein the gate is responsive to current to vary the gate electric potential. 3. The apparatus of claim 1 wherein the suppressor is responsive to current to vary the suppressor electric potential. 4. The apparatus of claim 1 wherein the at least one of the gate and suppressor is responsive to current produced by the electrons emitted from the cathode to vary at least one of the gate and suppressor electric potentials. 5. The apparatus of claim 1 wherein the at least one of the gate and suppressor is responsive to current produced by an external source to vary at least one of the gate and suppressor electric potentials. 6. A method corresponding to an apparatus having a cathode region, a gate region, a suppressor region, and an anode region arranged in a pattern, the method comprising: applying a gate electric potential from the gate region to selectively release a first set of electrons from a bound state in the cathode region; applying a suppressor electric potential from the suppressor region to selectively release a second set of electrons from emission from a bound state in the anode region, the anode region having an anode electric potential that is greater than a cathode electric potential of the cathode region;passing a portion of the first set of electrons through a gas-filled region and binding the passed portion of the first set of electrons in the anode region; and changing the pattern. 7. The method of claim 6 wherein the cathode region and the gate region are separated by a cathode-gate separation distance, and wherein changing the pattern includes changing the cathode-gate separation distance. 8. The method of claim 6 wherein the suppressor region and the anode region are separated by a suppressor-anode separation distance, and wherein changing the pattern includes changing the suppressor-anode separation distance. 9. The method of claim 6 wherein the cathode region and the anode region are separated by a cathode-anode separation distance, and wherein changing the pattern includes changing the cathode-anode separation distance. 10. The method of claim 6 further comprising: measuring a current in the anode region; and changing the pattern based on the measured current. 11. The method of claim 6 wherein changing the pattern includes: applying a force to an element in at least one of the cathode region, gate region, suppressor region, and anode region. 12. The method of claim 11 wherein the force includes a magnetic force. 13. The method of claim 11 wherein the force includes a mechanical force. 14. The method of claim 13 further comprising: applying the mechanical force with a MEMS. 15. The method of claim 13 further comprising: applying the mechanical force with a piezoelectric actuator. 16. The method of claim 6 further comprising: measuring a relative thermodynamic efficiency of the apparatus; and changing the pattern based on the measured relative thermodynamic efficiency. 17. The method of claim 6 wherein changing the pattern includes: applying a resonator to an element in at least one of the gate region and the suppressor region; and changing the pattern substantially periodically with the resonator. 18. The method of claim 17 wherein changing the pattern further includes: tuning the resonator. 19. The method of claim 6 further comprising: measuring a current in the anode region after changing the pattern; and changing the pattern based on the measured current. 20. The method of claim 6 wherein changing the pattern includes: applying a grid electric potential from a grid region to vary the trajectory of the first set of electrons. 21. The method of claim 6 wherein changing the pattern includes: changing at least one of the gate electric potential, the suppressor electric potential, and the anode electric potential. 22. The method of claim 6 wherein each of the cathode region, gate region, suppressor region, and anode region has a relative position, and wherein changing the pattern includes: determining an initial relative position corresponding to at least one of the cathode region, gate region, suppressor region, and anode region; and changing the pattern to resume the initial relative position.
