Tesla ‘Monster’ Cybertruck concept makes traditional monster trucks look tame

In the world of extreme auto, there are no machines that are more intimidating than monster trucks. With their massive engines and giant tires, monster trucks are associated with pure automotive mayhem and insanity. And if there is anything that’s still largely missing from the monster truck scene, it is the presence of all-electric vehicles. A Tesla Cybertruck could probably change this status quo.

Automotive 3D concept specialist shubbak.3D recently shared his take on what a “Monster Edition” of the Tesla Cybertruck could look like. The artist did pretty well in his concept, adding classic monster truck flourishes to the already domineering Cybertruck. The beast of the machine is pictured with numerous modifications such as a body kit, high suspension, and giant wheels.

Tesla’s New Structural Battery Pack — It’s Not Cell-to-Pack, It’s Cell-to-Body

Tesla’s Battery Day was not just full of surprises. When you read between the slides, Tesla made a lot of product announcements, many of which are still awaiting their discovery. The one this article is about is Tesla’s new battery pack.

What most people didn’t realize is that Tesla is abandoning its famous battery skateboard design. For those who didn’t know, until now, Tesla’s vehicles were composed of the body and a flat battery “skateboard” on the bottom that, as Tesla would say, are married together in the factory. We even witnessed the ceremony in person. Originally, the skateboard design was developed because it provided a low center of gravity and strong safety benefits, as well as the ability to quickly swap battery packs instead of just Supercharging if Tesla went down that road.

How emotion AI is used in a study of distracted driving

A pioneer in Emotion AI, Rana el Kaliouby, Ph.D., is on a mission to humanize technology before it dehumanizes us.

At LiveWorx 2020, Rana joined us to share insights from years of research and collaboration with MIT’s Advanced Vehicle Technology group.

Part demo and part presentation, Rana breaks down the facial patterns that cameras can pick up from a tired or rested driver, and observations from the first ever large-scale study looking at driver behavior over time.

World’s biggest wind and solar producer now worth more than ExxonMobil

Renewable energy is now richer than the Oil industry.

In yet another sign of the pace of the global energy transition – and the massive switch taking place in the investment community – the market value of company that describes itself as the world’s biggest producer of wind and solar power, US utility NextEra, has overtaken that of what used to be the world’s most valuable company, oil major ExxonMobil.

The flip occurred last last week, when NextEra overtook ExxonMobil to become the largest energy company in the US by market value. As Forbes reported, an investment in NextEra a decade ago would have delivered to return of 600 per cent, while an investment in ExxonMobil would have returned minus 25 per cent.

The shift is as significant as the one the world has seen in the auto industry, with electric vehicle maker Tesla overtaking the biggest car companies in the world in the last year, to the point where it is now valued at more than the next five biggest global car makers combined, despite producing just a fraction of the number of cars.

Why this space age airplane could change flying forever

Airbus’s plan to bring to market a zero-emission passenger aircraft by 2035 means it needs to start plotting a course in terms of technology in 2025. In fact it needs to plot several courses.

It looks like something out of “Star Trek,” and runs on a fuel experts once thought “crazy,” but Airbus hopes that in 15 years we’ll be flying into a greener future aboard this new zero-emission aircraft concept.

Aerodynamicists reveal link between fish scales and aircraft drag

The team’s findings have been published in Nature: Scientific Reports: “Transition delay using biomimetic fish scale arrays,” and in the Journal of Experimental Biology: “Streak formation in flow over biomimetic fish scale arrays.”

Reducing drag means faster aircraft speeds and less fuel consumption—an important area of study for aerodynamicists such as Professor Bruecker, City’s Royal Academy of Engineering Research Chair in Nature-Inspired Sensing and Flow Control for Sustainable Transport, and City’s Sir Richard Oliver BAE Systems Chair for Aeronautical Engineering.

Through their biomimetic study, Professor Bruecker’s team has discovered that the fish-scale array produces a zig-zag motion of fluid in overlapping regions of the surface of the fish, which in turn causes periodic velocity modulation and a streaky flow that can eliminate Tollmien-Schlichting wave induced transition to reduce by more than 25 percent.
