Abstract:
A photovoltaic system (10) comprising planar photovoltaic elements (12), the top of which is hit by solar irradiation (S) such that electricity is generated that is fed into a power grid (14) and/or is supplied to a battery unit, is characterized in that a cooling coil (20) that communicates with a first heat pump via a heat pump cycle is arranged below each photovoltaic element (12). Said cooling coil (20) feeds the process heat generated during operation of the photovoltaic element (12) to the first heat pump which communicates with a first carrier medium cycle (22) containing a first carrier medium. Furthermore, a heat accumulator unit (24) containing a heat accumulating medium is arranged in the first carrier medium cycle (22), the thermal energy of the first carrier medium being transferred to the heat accumulating medium within the heat accumulator unit (24). In addition, at least one other heat consumer cycle (30) containing a second carrier medium communicates with the heat accumulator unit (24), and the thermal energy of the heat accumulating medium is transferred to the second carrier medium of the other heat consumer cycle (30) as needed.
Abstract:
A method and device to optimize the cumulative beneficial effect of harvesting all available forms of lost energy, including energy that is lost while a vehicle is in motion (e.g., kinetic, inertia, friction, thermodynamic, and aerodynamic losses). The cumulative energy that is recovered is converted to electrical energy which powers the on-board electrolyzer to produce more hydrogen and oxygen while the system is in operation and stationary. Stationary, passive means of energy, solar, wind, hydro, etc. will also be available to power the electrolyzer. The system also contemplates utilizing passive means of energy to power a non-mobile system which incorporates an internal or external combustion engine in place of a fuel cell.
Abstract:
Different types of energy storage systems are described, in particular hydro-pneumatic storage systems. In one, energy is stored by compressing gas in a chamber (44,45,54,55) with a liquid piston and released by gas expansion. A spray head or grid at the top of the chamber (44,45,54,55) supplies liquid as a shower through the gas being compressed or expanding in the cylinder (11,12) to maintain an isothermal condition. In another, energy is stored from an array of solar cells connected to an array of supercapacitors forming an auxiliary storage, and a main energy storage device such as a hydro-pneumatic storage system, for supply to an AC or DC network. The efficiency is improved by connecting the solar cells via the array of supercapacitors to the AC or DC network. An immersed hydro-pneumatic storage device for off-shore/on-shore power generation systems comprises a cylinder that is immersed in a liquid mass, wherein energy is stored by compressing gas with a liquid piston and energy is released by gas expansion. The mass of liquid maintains an isothermal condition in the cylinder during compression and expansion.

Abstract:
A method and apparatus which includes a displacement engine which is capable of moving itself and a payload from one location to another without the expulsion of reaction mass or without applying reaction forces to the external environment. This displacement engine constitutes a unidirectional motion machine which accomplishes a displacement of its location by making a series of small jumps which upon completion leave the machine with the same linear momentum it had initially. The machine components basically include a bolus projector (18) for projecting a bolus (16) of projection material, preferably a heavy fluid like material over a distance at high speed to a bolus receiver (20). From the bolus receiver (20), the material flows at a low speed through a reservoir (22) which provides projection material for a new bolus to the bolus projector (18). One or more displacement engines of this type are attached to a vehicle (138) in space and are electrically powered by solar cells and/or vehicle batteries (138).

Los velos colectores cuelgan de una estructura de portales de gran altura y están constituidos por espejos adheridos a una trama de cables, formando una superficie de topología variable, que puede variar su forma y posición estirando e inclinando su estructura de soporte, la cual, puede girar para el seguimiento de la posición del sol. Además, se establece un receptor que se instala en un puente que se desarrolla longitudinalmente y en altura sobre el campo solar. Para cada mecanismo de recepción, existe la alternativa de unidades receptoras modulares móviles tipo funicular o un sistema fijo adherido al puente en series longitudinales. La estructura del puente mantiene una vía de servicio, una zona longitudinal para la instalación de tubos matrices de fluido térmico y una red de evacuación de potencia según el mecanismo de recepción incorporado.
