Driving at night might be a scary challenge for a new driver, but with hours of practice it soon becomes second nature. For self-driving cars, however, practice may not be enough because the lidar sensors that often act as these vehicles’ “eyes” have difficulty detecting dark-colored objects. Research published in ACS Applied Materials & Interfaces describes a highly reflective black paint that could help these cars see dark objects and make autonomous driving safer.

Lidar, short for light detection and ranging, is a system used in a variety of applications, including geologic mapping and self-driving vehicles. The system works like echolocation, but instead of emitting sound waves, lidar emits tiny pulses of near-infrared light. The light pulses bounce off objects and back to the sensor, allowing the system to map the 3D environment it’s in. But lidar falls short when objects absorb more of that near-infrared light than they reflect, which can occur on black-painted surfaces. Lidar can’t detect these dark objects on its own, so one common solution is to have the system rely on other sensors or software to fill in the information gaps. However, this solution could still lead to accidents in some situations. Rather than reinventing the lidar sensors, though, Chang-Min Yoon and colleagues wanted to make dark objects easier to detect with existing technology by developing a specially formulated, highly reflective black paint.

Researchers in China have developed a water-based battery, which is claimed to be much safer and energy-efficient than “highly flammable” non-aqueous lithium batteries.

Interestingly, the researchers say that these new batteries will be twice as energy-dense as traditional lithium-ion options. This holds the potential to revolutionize the electric vehicle industry.

Moreover, aqueous batteries use water as the solvent for electrolytes, enhancing their safety. Traditional non-aqueous lithium-ion batteries have a high energy density, but their safety is compromised due to the flammable organic electrolytes, a component that allows the battery to charge and discharge, they utilize.

They arrived back to a hero’s welcome as thousands gathered to witness the landing. Both Rutan brothers and Yeager were each awarded a Presidential Citizens Medal by President Ronald Reagan, who described how a local official in Thailand at first “refused to believe some cockamamie story” about a plane flying around the world on a single tank of gas.

“We had the freedom to pursue a dream, and that’s important,” Dick Rutan said at the ceremony. “And we should never forget, and those that guard our freedoms, that we should hang on to them very tenaciously and be very careful about some do-gooder that thinks that our safety is more important than our freedom. Because freedom is awful difficult to obtain, and it’s even more difficult to regain it once it’s lost.”

Richard Glenn Rutan was born in Loma Linda, California. He joined the U.S. Air Force as a teenager and flew more than 300 combat missions during the Vietnam War.
