Elon Musk had a sexual relationship with a former SpaceX intern, who he later hired onto his executive team, according to The Wall Street Journal. He also had a sexual relationship with a second employee. And a third woman alleged that Musk asked her several times to have his children; she refused. He then denied her a raise and complained about her performance.

One of the women who Musk had a sexual relationship also drew the ire of SpaceX President Gwynne Shotwell, who accused her of having an affair with Shotwell’s husband. When the woman reported this to HR, HR told Shotwell. “Shotwell told the HR department at SpaceX that she wanted the woman removed from the office of the chief executive,” The Wall Street Journal wrote.

The Journal’s article cites text messages, emails, and other documents. It is based on interviews with more than 48 people, including friends and family members of the women, as well as former employees.

Musk didn’t reply to WSJ’s requests for comment. Shotwell said the WSJ’s request for comment “paint[s] a completely misleading narrative” of what working for SpaceX is like, and that the WSJ story doesn’t reflect SpaceX’s culture. She also said that SpaceX investigates all harassment complaints and responds appropriately.

Kenworth has unveiled its latest innovation, the SuperTruck 2, at the Advanced Clean Transport expo in Las Vegas. This sleek and aerodynamic truck is the result of a six-year collaboration with the U.S. Department of Energy aimed at improving freight efficiency without abandoning diesel as the primary energy source.

Pushing the boundaries of efficiency

The SuperTruck 2 surpassed the company’s expectations, achieving a remarkable 136% improvement in efficiency over the 2009 Kenworth T660, which was considered the most fuel-efficient truck at the time. This feat was accomplished through a combination of improved fuel efficiency, reaching up to 12.8 mpg, and a significant weight reduction of over 7,000 pounds.

Aerodynamic design and weight savings

The aerodynamic design of the SuperTruck 2 is a standout feature, resembling a bullet train with a central cockpit, a narrowed nose, and sloped forehead. The truck also features low skirts, fully enclosed wheels within the bodywork, and slim camera stalks with night vision capabilities, replacing the traditional side mirrors. These design elements contribute to an astonishing 48% reduction in drag.

Weight savings were also a crucial factor, with the SuperTruck 2 tractor and trailer weighing in at 26,100 pounds, representing a 7,100-pound reduction compared to a typical tractor-trailer configuration. Lightweight, low-rolling-resistance tires, a smaller 80-gallon fuel tank, and innovative materials and design considerations all contributed to this significant weight reduction.

TESLA SEMI’S IMPRESSIVE PERFORMANCE ON ICE MARKS ANOTHER MAJOR TRIUMPH

Power train and driver amenities

The SuperTruck 2’s power train is equally impressive, combining a PACCAR MX-11-based diesel engine, a TX-12 automated transmission, and a 48-volt electric generator to create a mild hybrid system. This system charges lithium-ion batteries through regenerative braking, powering electric fans, steering, coolant, and HVAC systems, which were previously mechanically driven.

In bench testing, this power train achieved a record 55.7% engine efficiency rating, a significant improvement over today’s modern diesel engines, which demonstrate around 47% efficiency.

For drivers, the SuperTruck 2 offers a unique experience with a panoramic view from the central cockpit, a configurable 15-inch digital display and a sleeper berth featuring a fold-down bed and a rotating tabletop for added convenience.

Future-proofing and commercialization

While the SuperTruck 2 is powered by a diesel engine, Kenworth designed the overall layout to be power train-agnostic, capable of accommodating battery-electric or hydrogen fuel cell-powered drive systems in the future.

Kenworth acknowledges the challenges ahead in achieving a carbon-neutral society by 2050 and views the SuperTruck 2 program as an opportunity to explore and commercialize new technologies more quickly.

Kurt’s key takeaways

Kenworth’s SuperTruck 2 is a remarkable achievement, showcasing the company’s commitment to innovation and pushing the boundaries of efficiency in the trucking industry. While the SuperTruck 2 itself may not go into production, the technologies and design concepts developed during this project could pave the way for future commercial vehicles that are more efficient, environmentally friendly, and driver-focused.

Elon Musk has dropped his lawsuit against OpenAI and its CEO, Sam Altman, accusing the company of a breach of contract and allegedly abandoning its mission of creating AI technology to benefit humanity. As reported earlier by CNBC, the case was dismissed without prejudice, meaning Musk can file it again.

Musk’s decision to withdraw the lawsuit, filed in a California state court in February, comes just one day before a scheduled hearing where the judge would’ve reviewed OpenAI’s request to dismiss the case. It’s also one day after Musk said he would ban Apple devices at his companies if the company integrates OpenAI’s technology into the iPhone and Mac “at the OS level,” among other bizarre threats.

His lawsuit alleged that OpenAI breached an agreement reached with Musk and other founding members, all of whom committed to making OpenAI a nonprofit and keeping its technology open source.

Musk is straightforwardly alleging that OpenAI breached a contract that does not exist. It is simply not a thing! The complaint makes reference to a “Founding Agreement,” but no such Founding Agreement is attached as an exhibit, and the breach of contract claim admits that the “Founding Agreement” is basically a vibe everyone caught in some emails.

OpenAI denied Musk’s claims shortly after he filed the lawsuit, saying the billionaire wanted “absolute control” of the company by merging it with Tesla. The company also said there is “no agreement at all” with Musk.”
