Mirror Switches Between Reflective and Transparent States

A flexible mirror film electrically switches between reflective and transparent states. By applying (+) voltages, hydrogenation occurs and creates transparency. When (-) voltages are used, the switchable mirror returns to its original reflective state within 10 seconds. The technology allows switchlevel control of the passage of solar radiation, thereby reducing cooling load.

Hovering Aerial Vehicles Use Wireless Energy Supplied from Ground

New electrically charged, polarized, proprietary alloys create thrust to lift small aircraft, commonly referred to as Personal Ultralight Vehicles (PAVs), without the need of a propeller, jet, balloon, or rockets. The ion electric air propulsion is considered a clean technology that has none of the carbon emissions or volatile fuels involved with combustion engines. A ground-based broadcast power system and onboard rectenna eliminates the need for onboard power storage and results in more lift range and higher payload.

Fast-Charge Technology Finds Battery “Sweet Spot”

A technology recharges batteries in up to one-tenth the time of conventional methods. The device creates conditions within the battery that allow power to be input as fast as the cell can accept the charge. By creating a charging “ecosystem,” the optimum battery charging conditions are present which, in turn, cause the necessary redox reactions to occur at a very fast rate, with little to no side reactions occurring from an input of excess energy.

Technology Produces Electrically Conductive Polyester

New polyester compositions feature desired electrical characteristics without unduly deteriorating the other valued melt viscosity, processing, and shaped article properties. The electrically conductive polyester has strong conductivity at low carbon black loading. The use of carbon black with specific physical properties is critical for achieving the desired mix of electrical and processing traits. The carbon black component may be added at the monomer stage, such as with the dicarboxylic acid or with the glycol, or to the initial (trans)esterification product.

Magnetic Device Separates Hydrogen from Oxygen

High temperatures have been used to dissociate water, but in many cases, the oxygen and hydrogen recombine when temperatures drop. A new device magnetically separates hydrogen from oxygen at elevated temperatures. Steam enters a reaction chamber, heats to over 150 °C in a focused solar beam, and dissociates into hydrogen and oxygen. The ionic gases then pass through a magnetic field, where they experience opposing forces and can be drawn off individually. Once the ions are diverged, they are separated by a physical barrier. The temperature then rapidly decreases, causing the separated ions to recombine into H2 and O2.

Piezo-Driven Pressure Controller Saves Heat

Using a piezo-actuated valve and an integral, closed-loop pressure control circuit, a modular controller maintains the pressure of non-corrosive to mildly corrosive gases. The Active Pressure Controller (APC) consumes minimal power (

Piezo-Electric Actuator Provides Motion Control Alternative

An alternative piezo-electric ceramic actuator simultaneously provides greater force and deflection, while producing no appreciable magnetic field or heat. The RLP domed piezo, a PZT disk laminated between two metal layers under heat and pressure, increases deflection 1,000-fold from an unmodified 0.2 micron to 200 microns. Viva, a scalable actuator, utilizes a pre-loaded stack of PZT ceramic piezos that flex against a fixed base. The device has one or two output arms that mechanically amplify movement. Without the magnetic signature, Viva’s linear motion can be converted to rotary motion to replace brushless DC motors.
