Hypersonic planes could fly from Sydney to Los Angeles in just an hour. What’s standing in the way of such ultra-fast planes becoming reality is our understanding of how the turbulence they generate as they […]
A research team has developed an extrapolation-based Doppler resolution enhancement algorithm for frequency modulated continuous wave radars. The algorithm improves system performance, offering an advancement that is superior to existing ultra-high-resolution technologies.This post was originally […]
Autonomous vehicles (AVs) have been tested as taxis for decades in San Francisco, Pittsburgh and around the world, and trucking companies have enormous incentives to adopt them.This post was originally published on this site
The Société de transport de Montréal (STM), the city’s urban transit authority, plans to make its network completely electric by 2040 by adding 140 electric buses to its fleet annually to meet this target. It’s […]
By using two propellers that rotate in opposite directions, a ship can use less energy to move forward. New knowledge means that more ships can use the technology, including Hurtigruten’s Sea Zero project for its […]
Manufacturing sustainable aviation fuel with CO₂ byproducts of ethanol production could reduce carbon intensity by more than 80% compared to fossil fuels.This post was originally published on this site
A battle for control of a little-known chipmaker has threatened global auto production by choking off the semiconductor supply chain, though there are signs the crisis is inching toward a resolution.This post was originally published […]
People drive significantly less in European cities with a metro system than in cities that only have trams or no rail-based public transport at all. This is shown by a new study from the Complexity […]
A next-generation fire suppression system capable of autonomously detecting oil fires aboard naval vessels and precisely targeting and extinguishing them even in maritime environments has been developed domestically for the first time.This post was originally […]
A new study finds that composite metal foam (CMF) can withstand tremendous force—enough to punch a hole in a railroad tank car—at much lower weight than solid steel. The finding raises the possibility of creating […]
