摘要： A storage heater for storing heat and for heating a fluid, such as water, has an enclosure defining a chamber therein. The chamber has a lower portion and an upper portion with a heating element being disposed within the enclosure. A tube through which the fluid flows has an inlet and an outlet, both being disposed outside of the enclosure, and has a portion interconnecting the inlet and the outlet that passes through the enclosure. A densely packed bed of phase change material pellets is disposed within the enclosure and is surrounded by a viscous liquid, such as propylene glycol. The viscous liquid is in thermal communication with the heating element, the phase change material pellets, and the tube and transfers heat from the heating element to the pellets and from the pellets to the tube. The viscous fluid has a viscosity so that the frictional pressure drop of the fluid in contact with the phase change material pellets substantially reduces vertical thermal convection in the fluid. As the fluid flows through the tube heat is transferred from the viscous liquid to the fluid flowing through the tube, thereby heating the fluid.

摘要： A storage fluid heater for heating a fluid, employs a heat storage unit, a heating element thermally coupled to the heat storage unit, and a heat recovery tube thermally coupled to the heat storage unit. The recovery tube is made from a material having a coefficient of thermal expansion so that as the average temperature of the heat storage unit near the heat recovery tube increases, the surface area of gaps between the heat recovery tube and the storage unit increases, causing the contact resistance between the heat storage unit and the heat recovery tube to increase. The temperature of the fluid flowing within the heat recovery tube is thereby limited to a predetermined maximum. A structure that relieves excess pressure when the flow of fluid through the tube is stopped has an expansion tank connected to the fluid inlet of the tube.

摘要： A rectenna is a combination of an antenna and a rectifier (diode). Because of limitations in nanotechnology fabrication, it has not been possible to develop rectennas that can operate in the visible frequency range. Current work has gone to producing rectennas that operate in the far infrared (thermal emission) frequency range. To harvest solar energy with rectennas to produce electric power and since rectennas cannot operate at such high frequencies, the present invention provides rectenna configurations to overcome this problem.

摘要： A process and device to capture of CO2 at its originating source, such as a power plant, is disclosed. Absorbent material is recharged by desorbing CO2, so that it may be sequestered or used in another application. Continual recharging results in loss of absorbent surface area, due to pore plugging and sintering of particles. Calcium oxide or calcium hydroxide was immobilized to a fibrous ceramic-based fabric substrate as a thin film and sintered, creating an absorbent material. The samples were characterized, showing continuous cyclic carbonation conversions between about 62% and 75% under mild calcination conditions at 750° C. and no CO2 in N2. Under the more severe calcination condition at 850° C. and 20 wt % CO2 in N2, yttria fabric was superior to alumina as a substrate for carbon dioxide capture and the reactivity of the calcium oxide absorbent immobilized to yttria was maintained at the same level in the 12 cycles.
