NASA Flywheel for iPad

John H. Glenn Research Center, Cleveland, Ohio NASA Flywheel is an augmented reality application intended to highlight NASA Glenn’s research efforts in the area of flywheel energy storage systems. The app utilizes a printed optical target, available on the GRC Flywheel Program brochure and through the NASA Glenn Web portal, to present users with 3D views of flywheel hardware and space applications. Additional video and imagery are also included in the application package. The software has been compiled and bundled as an iOS app for the iPad, and is intended for release through the Apple App Store.

Three-Dimensional Photovoltaics Array for Laser-Based Power Transfer

Potential applications include situations in which there is a need to create electrical power at a remote location. Goddard Space Flight Center, Greenbelt, Maryland A standard solar array is a flat panel configured of many individual solar cells, wired in series or parallel, depending on their junction configuration and material. Since the solar flux is constant depending on the distance from the Sun, the maximum energy conversion for a given solar panel depends upon the capability to absorb as many spectral peaks as possible (different materials) across the total solar spectrum. If the radiative source is a man-made device such as a laser, parked in a different orbit or on Earth, then the impinging intensity is narrow spectrally, coherent and accurately pointed, and capable of very high intensities. Thus, the materials can be tailored to match the incoming radiation for maximum absorption.

Nanowire-Based Piezoelectric Power Generation

Energy scavenging is appealing for powering sensors, and for charging cellphones and small consumer electronics. Ames Research Center, Moffett Field, California Sensors have improved in terms of size, capability, and power consumption, but their deployment in remote areas is limited by battery power supplies. Using piezoelectric (PE) materials for energy scavenging is a possible way to remedy the situation. The technology developed in this work converts existing sources of nonpolluting energy (mechanical strain) from nature into electricity. The quantity of energy produced is not massive, but it can be easily generated from free sources such as vibration and electromagnetic waves.
