Abstract: The current invention uses a combination of technologies from dye-sensitized solar cells, and from thermionic generators, to form a unique, efficient, broad spectrum solar radiation to electric power converter. Light passing through the cell first passes through a dye-sensitized matrix of nanoporous semiconductor. Light within the absorption spectrum of the dye is absorbed and converted into electrons which are injected into the conduction band of the semiconductor matrix. Light, which is not absorbed by the dye, passes on to cathode. The cathode is heated upon absorbing the incoming radiation. At a temperature dependent on the work function of the cathode, the cathode emits electrons thermionically, thereby cooling the cathode. These electrons replenish the electrons in the dye, thus completing the flow of current between cathode and anode. The hot cathode is thermally isolated from portions of the device at ambient temperature, thereby minimizing parasitic thermal loss.

Abstract: A reciprocating internal combustion engine is based on Homogenous Charge Compression Ignition (HCCI) that occurs in a deformable, resonant combustion chamber and that is coupled mechanically to efficient, resonant, electromechanical transducers acting as motors and generators. The mechanical coupling also implements fuel/air intake valves and exhaust valves. Embedded sensors allow an electronic control system to start the engine and thereafter to maintain operational configuration of the moving components in response to the effects of imperfect mechanical fabrication and/or assembly and dynamic changes in mechanical properties of the materials with run-time temperature and engine life.
