Toyota built an internal combustion engine that sips hydrogen, and it sounds awesome

Posted by in categories: sustainability, transportation

Japanese auto giant Toyota is working on a new-age hydrogen vehicle. When the words Toyota and Hydrogen are in the same sentence, the hydrogen-powered Toyota Mirai comes to mind. Still, the Mirai is a hydrogen-electric car or FCEV (fuel-cell electric vehicle). It uses hydrogen fuel to convert electricity and power an onboard electric motor. This time, Toyota came up with something different.

“At the end of last year, we built a prototype that provided that ‘car feeling’ that car lovers love, such as through sound and vibration, even though we were dealing with environmental technology, said Koji Sato, Chief Branding Officer, and Gazoo Racing Company President. ” It was only recently that I realized, as one thing led to another, that we could use technologies that we had on hand.”

The Race to Build Self-Driving Trucks Has Four Horses and Three Jockeys

Posted by in categories: robotics/AI, transportation

It’s likely that safety drivers will remain in cabs for years to come as companies hone their sensor technology and train their software for every highway scenario. It’s expensive and painstaking work that can overwhelm even the best-run start-ups. The consensus within the industry is that three contestants stand the best chance to make it to the finish line: “It’s TuSimple, Aurora and Waymo,” says Grayson Brulte, co-founder of Brulte & Co., a consulting firm focused on transportation. TuSimple, a San Diego based-company that raised $1.35 billion in an initial public offering in April, is in the pole position, as Brulte sees it, because of its singular focus on trucking and its partnership, begun three years ago, with Navistar International to build autonomous trucks. “They’ve got the head start on it,” says Brulte.


These are the companies set to dominate the highways of tomorrow.

Oshkosh takes victory lap over Postal Service delivery truck contract

Posted by in categories: sustainability, transportation

Oshkosh can make 100% battery-electric delivery trucks for the U.S. Postal Service, likely dashing Workhorse’s hopes of reigniting the competition.


Oshkosh Truck Corp. (NYSE: OSK) can make 100% battery-electric delivery trucks for the U.S. Postal Service, undercutting an assertion by Workhorse Group (NASDAQ: WKHS) that its being passed over for the contract dooms the mail service to remaining a source of planet-warming greenhouse gas emissions.

Here’s how the Koenigsegg Gemera’s 600bhp camless engine works

Posted by in categories: business, transportation

One critical part of the Koenigsegg Gemera’s brain-scrambling powertrain is its ‘Freevalve’ petrol engine. You might have glossed over it while trying to compute the outputs, and they way that engine combines with three electric motors to produce, er, 1700bhp in all. Or in metric, 1.27 Megawatts. Or the power draw of a couple of hundred houses cooking dinner.

Christian von Koenigsegg, though, will talk for hours about this engine. He’s so affectionate about the thing he’s got a nickname rather than the usual dreary car-business habit of codenames. This, then, is the Tiny Friendly Giant.

Giant because 600bhp. Tiny because it’s just two litres and three cylinders. Maybe two litres isn’t that tiny in displacement (though CvK’s cars have mostly had big V8s) but it’s physically very small and easy to package. It has just the three cylinders, and no overhead camshaft casings, and no camshaft drive on the front.

Swap and go: electric trucks to run between Sydney and Brisbane using exchangeable batteries

Posted by in category: transportation

“It’s usually the diesel engine that’s worn out, not the rest of the truck,” he said, “so, instead of spending money on the rebuild, they can convert their trucks.”


Batteries can be swapped in three minutes, removing the need for trucks to plug in and charge.

Jetoptera VTOL aircraft design features “bladeless fans on steroids”

Posted by in categories: energy, transportation

Seattle-based company Jetoptera says its air-accelerating Fluidic Propulsive System, which works a lot like a Dyson “bladeless” fan, produces thrust for half the fuel of a small turbojet while being the “most silent propulsion system in the skies.”

New Artificial Neuron Device Runs Neural Network Computations Using 100 to 1000 Times Less Energy

Posted by in categories: mathematics, robotics/AI, transportation

Training neural networks to perform tasks, such as recognizing images or navigating self-driving cars, could one day require less computing power and hardware thanks to a new artificial neuron device developed by researchers at the University of California San Diego. The device can run neural network computations using 100 to 1000 times less energy and area than existing CMOS-based hardware.

Researchers report their work in a paper published recently in Nature Nanotechnology.

Neural networks are a series of connected layers of artificial neurons, where the output of one layer provides the input to the next. Generating that input is done by applying a mathematical calculation called a non-linear activation function. This is a critical part of running a neural network. But applying this function requires a lot of computing power and circuitry because it involves transferring data back and forth between two separate units – the memory and an external processor.
