The turn signal is projected onto the road in a dynamic movement and indicates when the car is changing direction. Thanks to the high luminous intensity, the signal is clearly visible even in daylight.

Engineers evaluate reliability of pressure relief valves for liquid natural gas tanks in train derailment scenarios
In this image, natural gas is discharged through a two-inch diameter pipe and ignited as part of an SwRI-conducted test to evaluate pressure relief valves. Temperatures and heat fluxes were measured at different standoff distances to provide computer model validation data that can aid future researchers as they investigate a variety of accident scenarios.

Hundreds of cities have achieved zero road deaths in a year—here’s how they did it
Credit: Pixabay/CC0 Public Domain It’s National Road Safety Week and it comes on the back of a year in which 1,286 people died on Australian roads. The rising road toll—up 8.2% for the year to March—included 62 children. Tragically, road deaths remain the number one killer of children in Australia. Road deaths are not inevitable. […]
NASA uses small engine to enhance sustainable jet research
The DGEN380 Aero-Propulsion Research Turbofan (DART) is a small-scale jet engine NASA uses to test new aviation technology. DART is seen here inside its host facility, the Aero-Acoustic Propulsion Laboratory at NASA’s Glenn Research Center in Cleveland. This soundproofed chamber ensures researchers can understand the level of noise the engine is producing, as well as […]
Reducing operation emissions and improving work efficiency using a pure electric wheel drive tractor
Battery ballast system. Credit: Engineering (2024). DOI: 10.1016/j.eng.2024.01.026 Electric tractors are intended to be used in the field instead of traditional fuel tractors and can be used in greenhouse planting, indoor farming, mountainous operations, and other special operating scenarios. Unlike traditional fuel tractors, electric tractors have no exhaust emissions, rapid drive system response, flexible power […]
