Organic Photovoltaics - Forecasts for the Next Decade

Today there are multiple devices available for harnessing solar energy. Each device offers a different set of characteristics. Wafer-based devices consist of mono or polycrystalline and are the most mature technology due to the experience borrowed from the microelectronics industry.

Hybrid Power Management-Based Vehicle Architecture

Hybrid Power Management (HPM) is the integration of diverse, state-of-the-art power devices in an optimal configuration for space and terrestrial applications. The basic vehicle architecture consists of a primary power source, and possibly other power sources, that provides all power to a common energy storage system that is used to power the drive motors and vehicle accessory systems.

Enhanced Fuel-Optimal Trajectory-Generation Algorithm for Planetary Pinpoint Landing

An enhanced algorithm has been developed that builds on a previous innovation of fuel-optimal powered-descent guidance (PDG) for planetary pinpoint landing. The PDG problem is to compute constrained, fuel-optimal trajectories to land a craft at a prescribed target on a planetary surface.

Cool and Green: Vehicle Thermal Management

Air conditioning is a ‘must-have’ for most new cars. But the fluorocarbon refrigerant HFC-134a – the global standard – is one of the ozone-depleting greenhouse gases causing global warming. With these concerns, the European Union has passed regulations phasing out the compound beginning in 2011 and mandating the use of alternatives with less environmental impact.

Spring Tire

A new tire is made from helical springs, requires no air or rubber, and consumes nearly zero energy. The spring tire provides greater traction in sandy and/or rocky soil, can operate in microgravity and under harsh conditions, and is non-pneumatic.

LED Lighting for Maintenance and Construction Vehicles

Strobe or rotating beacon-type emergency lighting is a requirement on all Minnesota Department of Transportation (Mn/DOT) maintenance and construction vehicles. There is an effort to replace the standard warning lighting with LED-based lights in order to reduce cost of replacement and maintenance.

Revolution in Fasteners Helps Bridge the Gap 
to Greener Vehicles

With auto sales down as much as 40 percent, it can feel to some like the industry is coming apart. But a "revolution in fasteners" may soon help bridge the gap to greener vehicles, while increasing sales and lowering recall and warranty rates.
