NOVELTY - An object is moved by providing a catalyst (105) on a substrate (108). Reactants are placed in contact and interact with the catalyst. They generate phonons that propagate into the substrate and away from the catalyst. The phonons are directed towards the object.    USE - Extraction of electrical or mechanical energy from chemical reactions occurring on the surface of a catalyst before thermal equilibrium has been reached by the forms of the released energy. Electricity is generated using photon to electric energy or even phonon to piezoelectricity energy conversion using nanoclusters in the catalyst.    ADVANTAGE - The catalyst is operated at a high surface power density (excess of 10 W/cm2) or peak surface power density to enhance the efficiency of the photovoltaic semiconductors. The combination of high volume and mass power density, simplicity and lower temperatures operation makes the method and devices competitive and uniquely useful.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for:    (A) a method for generating electricity comprising forming species in highly excited states on a catalyst to radiate electromagnetic energy, and converting the electromagnetic energy into electricity with a photovoltaic collector;    (B) an electricity-generating device comprising a catalyst arranged on a substrate having a substrate diode (109) for receiving charge carriers from the catalyst; and    (C) a fluid-moving device comprising a catalyst, a substrate, and a hydraulic fluid in contact with a bottom side of the substrate. The catalyst acts as an acoustic waveguide for the phonons. It conveys the phonons to the bottom side of the substrate to move the hydraulic fluid in a preferred direction.    Upon Introduction of fuel (102) and an oxidizer (103) in the electricity-generating device to contact with the catalyst, charge carriers are emitted by the catalyst and an electrical potential is developed across the substrate.
