First Night Flight Using Solar Energy On the Horizon

The Solar Impulse HB-SIA - the first airplane designed to fly day and night without fuel - left the ground yesterday for the first time. Recent results from ground tests had verified the prototype's controllability, acceleration, braking paths, and engine power.

Reflective Switch Employed in Wind Turbines for RPM Sensing

The OPB732 Series long distance infrared reflective switch from TT electronics OPTEK Technology (Carrollton, TX) has been employed in a 6kW wind turbine for RPM sensing. Placed at the turbine rotor, the switch is used internally to sense RPMs, and that data is then transmitted to a customer-accessible Web site via GPRS.

New Pathway to Forming Hydrogen Storage Compounds

Scientists at the Carnegie Institution for Science have found that high pressure can be used to make a unique hydrogen-storage material. The researchers found that the normally unreactive, noble gas xenon combines with molecular hydrogen under pressure to form a previously unknown solid with unusual bonding chemistry.

Using Aerospace Approach, Engineers Design Wave Energy System

Aerospace engineers from the U.S. Air Force Academy are applying the principles that keep airplanes aloft to create a new wave energy system that is durable, efficient, and can be placed anywhere in the ocean - regardless of depth. While still in early design stages, computer and scale-model tests of the system suggest higher efficiencies than wind turbines.

NASA's Algae Bioreactor Licensed to Algae Systems, LLC

Earlier this year, NASA introduced an algae photo-bioreactor that grows algae in municipal wastewater to produce biofuel and a variety of other products. The NASA bioreactor is an Offshore Membrane Enclosure for Growing Algae (OMEGA), which won't compete with agriculture for land, fertilizer, or freshwater.
