Tesla on Thursday delivered its first electric semitrailer truck to PepsiCo, as the electric vehicle maker expands its offerings beyond passenger cars.
Elon Musk, the CEO of Tesla, drove a Semi to the delivery event, which was held at a factory near Reno, Nevada.
The Semi is the automaker’s all-electric, class-8 cargo trucks with a range between 300 and 500 miles on a single charge, depending on the model.
Massachusetts Institute of Technology (MIT) researchers are building swarms of tiny robots that have built-in intelligence, allowing them to build structures, vehicles, or even larger versions of themselves.
The subunit of the robot, which is being developed at MIT’s Center for Bits and Atoms, is called a voxel and is capable of carrying power and data.
“When we’re building these structures, you have to build in intelligence,” MIT Professor and CBA Director Neil Gershenfeld said in a statement. “What emerged was the idea of structural electronics — of making voxels that transmit power and data as well as force.”
Dahn, a world-renowned battery scientist and NSERC/Tesla Canada Chair, presented the exciting news during his keynote presentation (titled: More than a million miles and a century of life) at the international battery seminar (IBS) held 28–31 March 2022 in Orlando, Florida.
The term “Million Mile” battery first came to life after Dahn’s 2019 open access publication in Journal of The Electrochemical Society (JES) stating “we conclude that cells of this type should be able to power an electric vehicle for over 1.6 million kilometers (1 million miles) and last at least two decades in grid storage”.
Researchers advance efforts to create groups of robots that could construct almost anything.
When it comes to the manufacturing of commercial aircraft, different parts are manufactured at various locations. Before finally bringing them all together in a central plant and putting the finished aeroplane together, the tail components, the fuselage, and the wings are made at different plants.
Many other large structures, besides aircraft, are also built in sections.

LONDON, Nov 28 (Reuters) — Britain’s Rolls-Royce (RR.L) said it has successfully run an aircraft engine on hydrogen, a world aviation first that marks a major step towards proving the gas could be key to decarbonising air travel.
The ground test, using a converted Rolls-Royce AE 2100-A regional aircraft engine, used green hydrogen created by wind and tidal power, the British company said on Monday.
Rolls and its testing programme partner easyJet (EZJ.L) are seeking to prove that hydrogen can safely and efficiently deliver power for civil aero engines.
Researchers at the UPC’s Department of Electronic Engineering have developed a new type of magnetometer that can be integrated into microelectronic chips and that is fully compatible with the current integrated circuits. Of great interest for the miniaturization of electronic systems and sensors, the study has been recently published in Microsystems & Nanoengineering.
Microelectromechanical systems (MEMS) are electromechanical systems miniaturized to the maximum, so much so that they can be integrated into a chip. They are found in most of our day-to-day devices, such as computers, car braking systems and mobile phones. Integrating them into electronic systems has clear advantages in terms of size, cost, speed and energy efficiency. But developing them is expensive, and their performance is often compromised by incompatibilities with other electronic systems within a device.
MEMS can be used, among many others, to develop magnetometers—a device that measures magnetic field to provide direction during navigation, much like a compass—for integration into smartphones and wearables or for use in the automotive industry. Therefore, one of the most promising lines of work are Lorentz force MEMS magnetometers.
The test is a stepping stone to achieving carbon neutrality by 2050.
In what can be considered a promising first step towards transforming the aviation industry to become carbon-neutral, a project led by Rolls Royce and easyJet has successfully tested a modern-day jet engine that runs solely on hydrogen.
The prototype for the experiment, which was conducted at a test facility at the Ministry of Defence Boscombe Down, U.K., was a commonly-used Rolls-Royce AE-2100A regional aircraft engine. The turbine was supplied with ‘green’ hydrogen, which was made by splitting water into its constituent components at European Marine Energy Centre in the Orkney Islands, U.K.
“We are pushing the boundaries to discover the zero carbon possibilities of hydrogen, which could help reshape the future of flight,” Grazia Vittadini, chief technology officer of Rolls-Royce, said in a statement.
Tesla Semi carried 81,000 pounds for 500 miles on a single charge.
Just a few days before Tesla begins shipping the truck, Elon Musk has verified that Tesla Semi, the company’s Class 8 semi-truck, has successfully completed a crucial voyage.
Although there is no reason to question the outcome, it would be interesting to learn more about speed and energy usage. We are pretty interested in seeing some impartial vehicle tests.
Tesla.
Elon Musk recently tweeted that a Tesla Semi completed an 800-kilometer (500-mile) drive carrying 81,000 pounds (36,740 kilograms), which is nearly 100 percent of its Gross Combination Weight (GCW) of 82,000 pounds.
