When urban development takes place, a traffic impact assessment is often needed before a project is approved: What will happen to auto traffic if a new apartment building or business complex is constructed, or if a road is widened? On the other hand, new developments affect foot traffic as well — and yet few places study the effects of urban change on pedestrians.

A group of MIT researchers wants to alter that, by developing a model of pedestrian activity that planners and city officials can use in much the same way officials evaluate vehicle traffic. A study they have conducted of Melbourne, Australia, shows that the model works well when tested against some of the most comprehensive pedestrian data available in the world.

“Our model can predict changes in pedestrian volume resulting from changes in the built environment and the spatial distribution of population, jobs, and business establishments,” says Andres Sevtsuk, an associate professor in MIT’s Department of Urban Studies and Planning (DUSP) and lead author of a newly published paper detailing the results. “This provides a framework to understand how new developments can affect pedestrian flows on city streets.”

Tokyo-based aircraft manufacturer Tetra Aviation revealed its first commercially available personal eVTOL (electric vertical take-off and landing) Mk-5 just a short while ago. It happened in July at this year’s AirVenture OSHKOSH event in Wisconsin, touted the world’s greatest aviation celebration. Now the company follows with a flight demonstration of the aircraft in California.

How do you settle an argument with someone who’s clearly in the wrong? Well, you show them a live demonstration, even if it means putting your life on the line but in the end, you have to show them who’s the boss am I right?

That’s exactly what Destin Sandlin from SmarterEveryDay YouTube channel did by shutting off the helicopter midair to prove a point. A few years ago, Neil deGrasse Tyson had made a statement that “An airplane whose engine fails is a glider. A helicopter whose engine fails is a brick.” which did not sit well with the Youtuber and he decided to prove Tyson and everyone once and for all, that that statement was in fact wrong and the reality was different. The video was shot in 2016 but it has been making the rounds once again.

Tesla Giga Shanghai has officially exceeded the Fremont Factory’s output, according to Elon Musk’s calculations. As Tesla’s main export hub, Giga Shanghai’s output will play a significant role in the company’s global growth.

“We have three new factories. Giga Shanghai has done an incredible job. And Giga Shanghai now exceeds Fremont in production,” Musk announced at the 2021 Annual Shareholders Meeting.

Musk pointed out that Tesla Giga Shanghai took roughly 11 months to build and reached full volume production a year later. Since Giga Shanghai started operations, Tesla’s production and delivery numbers have noticeably increased.

The Artemis I Orion spacecraft is currently undergoing final checkouts before the critical milestone of transportation to the Vehicle Assembly Building for final stacking, integration, and checkout ahead of launch.

Meanwhile, the Orion crew modules for the Artemis II, III, and IV missions are also continuing assembly in their processing flows.

It’s okay, you’ve not clicked on “Green Plane Reports”, but every so often something from beyond the world of cars catches our attention.

This time, it’s electric flight. The concept is nothing new, and it’s even been alluded to by people like Elon Musk of Tesla, but for the time being it remains a true flight of fancy, rather than a working concept for passenger transportation.

Solar Impulse 2 which landed in Abu Dhabi, is first plane powered by the renewable energy source to tour the globe.

In a new paper, the researchers explain how the robot can impressively locate and retrieve an item, even if it is covered by other objects and completely out of view of the main camera. All the robot’s owner has to do is attach RFID tags — cheap, battery-free tags that send signals to the antenna — to their valuable possessions.

“This idea of being able to find items in a chaotic world is an open problem that we’ve been working on for a few years. Having robots that are able to search for things under a pile is a growing need in industry today. Right now, you can think of this as a Roomba on steroids, but in the near term, this could have a lot of applications in manufacturing and warehouse environments,” senior author Fadel Adib explained in MIT’s statement.
