Tesla Model Y Powered By Solar Panels On Its Roof — Smart Move?

Posted by in categories: sustainability, transportation

An intrepid DIY Tesla Model Y owner has done what many dream of doing — directly powered his Tesla with solar panels. That’s right, not happy with simply powering his car with house rooftop solar panels, he’s doing it with a solar panel array on the roof of his crossover.

This Tesla Model Y Performance owner created a folding solar array capable of charging 20-60mi per day via a 2000W-4000W system.

500-mile Tesla Semi starts delivery, features 1-megawatt charging

Posted by in category: transportation

Tesla late on Thursday started customer deliveries of its semi-trailer truck, which is dubbed the Semi.

The first customer was Pepsi, which placed an order for 100 of the Class 8 trucks following the debut in 2017. Budweiser and Walmart are among the other customers for the fully electric semi truck which features a central driving position, just like the McLaren F1 supercar.

Waymo’s Driverless Cars Are Hitting the Highway Sans Safety Drivers in Arizona

Posted by in categories: business, robotics/AI, sustainability, transportation

To back up the decision, Waymo pointed to its safety record and history building and operating self-driving trucks on highways. (The company shuttered its self-driving truck project last year to focus on taxis.) Including highways should also decrease route times for riders—especially from the airport—with some rides taking half the time.

Although highways are simpler to navigate than city streets—where cars contend with twists, turns, signs, stoplights, pedestrians, and pets—the stakes are higher. A crash at 10 or 20 miles per hour is less likely to cause major injury than one at highway speeds. And while it’s relatively straightforward (if less than ideal) for a malfunctioning robotaxi to stop or pull to the side of the road and await human help in the city, such tactics won’t do on the highway, where it’s dangerous for cars to suddenly slow or stop.

World’s First Hydrogen-Powered VTOL Jet Has BMW DNA and It Seems Like a Waste of Tech

Posted by in categories: biotech/medical, transportation

The world of VTOLs is fast expanding and promises to forever change the way air travel is made. There are several driving forces behind this expansion, ranging from the need to declutter our very congested cities and airports to the need to find better, faster, and cleaner means of transportation.

Scientists Train AI to Be Evil, Find They Can’t Reverse It

Posted by in categories: robotics/AI, transportation

How hard would it be to train an AI model to be secretly evil? As it turns out, according to AI researchers, not very — and attempting to reroute a bad apple AI’s more sinister proclivities might backfire in the long run.

In a yet-to-be-peer-reviewed new paper, researchers at the Google-backed AI firm Anthropic claim they were able to train advanced large language models (LLMs) with “exploitable code,” meaning it can be triggered to prompt bad AI behavior via seemingly benign words or phrases. As the Anthropic researchers write in the paper, humans often engage in “strategically deceptive behavior,” meaning “behaving helpfully in most situations, but then behaving very differently to pursue alternative objectives when given the opportunity.” If an AI system were trained to do the same, the scientists wondered, could they “detect it and remove it using current state-of-the-art safety training techniques?”

Unfortunately, as it stands, the answer to that latter question appears to be a resounding “no.” The Anthropic scientists found that once a model is trained with exploitable code, it’s exceedingly difficult — if not impossible — to train a machine out of its duplicitous tendencies. And what’s worse, according to the paper, attempts to reign in and reconfigure a deceptive model may well reinforce its bad behavior, as a model might just learn how to better hide its transgressions.

This hydrogen-powered supercar can drive 1,000 miles on a single tank

Posted by in categories: energy, sustainability, transportation

Hyperion, a California-based company, has unveiled a hydrogen-powered supercar the company hopes will change the way people view hydrogen fuel cell technology.

The Hyperion XP-1 will be able to drive for up to 1,000 miles on one tank of compressed hydrogen gas and its electric motors will generate more than 1,000 horsepower, according to the company. The all-wheel-drive car can go from zero to 60 miles per hour in a little over two seconds, the company said.

Hydrogen fuel cell cars are electric cars that use hydrogen to generate power inside the car rather than using batteries to store energy. The XP-1 doesn’t combust hydrogen but uses it in fuel cells that combine hydrogen with oxygen from the air in a process that creates water, the vehicle’s only emission, and a stream of electricity to power the car.

DARPA’s Mysterious X-Plane Will Revolutionize Flight by Breaking This Century-Old Aviation Design Paradigm

Posted by in category: transportation

DARPA is preparing to revolutionize flight as it moves forward with the development of its experimental X-plane, which the agency says will upend a century of flight technology with an aircraft featuring no moving control surfaces.

The X-65, a technology demonstrator with a 30-foot wingspan weighing slightly more than 7,000 pounds, is expected to be capable of reaching Mach 0.7.

The agency has been working with its partners at Aurora Flight Sciences, who were recently given the green light to construct a full-scale experimental aircraft that will demonstrate the company’s novel active flow control (AFC) actuators for its flight control system.

AI comes up with battery design that uses 70 per cent less lithium

Posted by in categories: robotics/AI, solar power, sustainability, transportation

Artificial intelligence can accelerate the process of finding and testing new materials, and now researchers have used that ability to develop a battery that is less dependent on the costly mineral lithium.

Lithium-ion batteries power many devices that we use every day as well as electric vehicles. They would also be a necessary part of a green electric grid, as batteries are required to store renewable energy from wind turbines and solar panels. But lithium is expensive and mining it damages the environment. Finding a replacement for this crucial metal could be costly and time-consuming, requiring researchers to develop and test millions of candidates over the course of years. Using AI, Nathan Baker at Microsoft and his colleagues accomplished the task in months. They designed and built a battery that uses up to 70 per cent less lithium than some competing designs.
