Electric motors and gas-alcohol engines could slash pollution levels and greenhouse gases from long-haul trucks.

Radar technologies were originally designed to identify and track airborne military targets. Today, they're more often used to detect motor vehicles, weather formations, and geological terrain. Until now, scientists believed that radar accuracy and resolution are related to the...

The Swingbed software applications provide for the control, command, fault detection, fault recovery, and telemetry monitoring aspects of the Amine Swingbed experiment. These software components are the Swingbed Loader Computer Software Configuration Item (CSCI),...

NASA Goddard Space Flight Center has developed technology that uses inductive power transfer (IPT) for wireless power interfaces between spaceflight elements (such as the payload, vehicle, and pad). Current spaceflight systems require traditional hardwire connections for power interfaces. This...

The EHD pump uses electric fields to move a dielectric fluid coolant in a thermal loop to dissipate heat generated by electrical components with a low-power system. The pump has only a few key components and no moving parts, increasing the simplicity and robustness of the system. In...

Designing any product — from complex car parts to wrenches — is a balancing act with conflicting performance tradeoffs. Making something lightweight, for instance, may compromise its durability.
