MIT team proposes SCR emission control for hybrid aviation turbines; reducing NOx by 95%

Green Car Congress

Now, MIT engineers are proposing using an ammonia-based selective catalytic reduction (SCR) system that could result in an approximately 95% reduction in NO x emissions in exchange for a ~0.5% The trend towards smaller engine cores with smaller mass flow rates in the core stream, presents new opportunities for emissions control.

Algorithm Uses Evolution To Design Robots

Cars That Think

To accomplish tasks, they need both a well-designed body and a “brain,” or controller. But there are few ways to optimize a robot’s design at the same time. Unless the designer is an algorithm. They presented the system at this year’s Conference on Neural Information Processing Systems. The same is true for robots.

MIT team develops new lane-change algorithm for autonomous cars

Green Car Congress

Most existing lane-change algorithms for autonomous cars have one of two drawbacks: Either they rely on detailed statistical models of the driving environment, which are difficult to assemble and too complex to analyze on the fly; or they’re so simple that they can lead to impractically conservative decisions, such as never changing lanes at all.

Video Friday: Robot Crash-Perches, Hugs Tree

Cars That Think

Here, we present a method that relies on passive wing morphing for crash-landing on trees and other types of vertical poles. Inspired by the adaptability of animals’ and bats’ limbs in gripping and holding onto trees, we design dual-purpose wings that enable both aerial gliding and perching on poles.
