4 Remarkable Elements Of The All-Electric Polestar 2

Posted by in categories: sustainability, transportation

Polestar may be a young brand, but its direction is clear: be the “guiding star” for the Volvo and Geely Car Groups when it comes to technology, performance, and sustainability.

Just last year, its debut car, the hybrid-electric two-door Polestar 1, began its initial production run to satisfy approximately 150 pre-orders. Deliveries are now underway, but Polestar – naturally – is already sailing forth towards its next phase, the all-electric five-door fastback Polestar 2.


Polestar’s latest brings the young brand’s future into sharper focus, distinguishing itself from its sibling brand Volvo while quite possibly outshining the competition, too.

A model for autonomous navigation and obstacle avoidance in UAVs

Posted by in categories: robotics/AI, transportation

Autonomous unmanned aerial vehicles (UAVs) have shown great potential for a wide range of applications, including automated package delivery and the monitoring of large geographical areas. To complete missions in real-world environments, however, UAVs need to be able to navigate efficiently and avoid obstacles in their surroundings.

Researchers at Luleå University of Technology in Sweden and California Institute of Technology have recently developed a nonlinear model predictive control (NMPC)-based computational technique that could provide UAVs with better navigation and obstacle avoidance capabilities. The NMPC approach they used, presented in a paper published in IEEE Robotics and Automation Letters, is based on the structure of OpEn (Optimization Engine), a parametric optimization software developed by Dr. Pantelis Sopasakis at Queen’s University Belfast.

Japan’s Flying Car Takes Off for the First Time with a Passenger On Board

Posted by in categories: futurism, transportation

SkyDrive claims the vehicle has been engineered to be easily embraced by people. “SkyDrive’s flying car has been designed to be a coupe embodying dreams and exuding charisma, such that it will be welcomed into people’s lives and used naturally,” reads the firm’s press release.

“The company hopes that its aircraft will become people’s partner in the sky rather than merely a commodity and it will continue working to design a safe sky for the future.”

SkyDrive also revealed that it will continue field testing the flying car under different conditions to hone its technology and hopefully acquire compliance with the safety provisions of the Civil Aeronautics Act.

Fusion Power Breakthrough: New Method for Eliminating Damaging Heat Bursts in Toroidal Tokamaks

Posted by in categories: nuclear energy, particle physics, transportation

Picture an airplane that can only climb to one or two altitudes after taking off. That limitation would be similar to the plight facing scientists who seek to avoid instabilities that restrict the path to clean, safe, and abundant fusion energy in doughnut-shaped tokamak facilities. Researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) and General Atomics (GA) have now published a breakthrough explanation of this tokamak restriction and how it may be overcome.

Toroidal, or doughnut-shaped, tokamaks are prone to intense bursts of heat and particles, called edge localized modes (ELMs). These ELMs can damage the reactor walls and must be controlled to develop reliable fusion power. Fortunately, scientists have learned to tame these ELMs by applying spiraling rippled magnetic fields to the surface of the plasma that fuels fusion reactions. However, the taming of ELMs requires very specific conditions that limit the operational flexibility of tokamak reactors.

Reaction Engines testing ammonia as carbon-free aviation fuel

Posted by in categories: energy, sustainability, transportation

Reaction Engines and Britain’s Science and Technology Facilities Council (STFC) have completed a concept study into the practicality of using ammonia as a jet aviation fuel. By teaming Reaction Engines’s heat exchanger technology with STFC’s advanced catalysts, they hope to produce a sustainable, low-emission propulsion system for tomorrow’s aircraft.

Modern jet engines use a variety of fuels based on kerosene that have a very high energy density that can propel aircraft well beyond the speed of sound and carry passengers and cargoes across the globe. Unfortunately, such fuels are also derived from fossil fuels and produce significant carbon dioxide emissions, which the airline industry and many governments have pledged to reduce radically by 2050.

One way of achieving these cuts is to look at alternatives to conventional jet fuels to power airliners. The problem is that most of these alternatives have much lower energy densities than standard aviation fuels and suffer from other drawbacks. For example, present-day battery technology would require future aircraft to be very small, short-range, and with little payload capacity. Meanwhile, liquid hydrogen could be a viable alternative, but so much of it would need to be carried that planes would have to be completely redesigned and new infrastructure built.

Transparent solar panels for windows hit record 8% efficiency

Posted by in categories: solar power, sustainability, transportation

In a step closer to skyscrapers that serve as power sources, a team led by University of Michigan researchers has set a new efficiency record for color-neutral, transparent solar cells.

The team achieved 8.1% efficiency and 43.3% transparency with an organic, or carbon-based, design rather than conventional silicon. While the cells have a slight green tint, they are much more like the gray of sunglasses and automobile windows.

“Windows, which are on the face of every building, are an ideal location for because they offer something silicon can’t, which is a combination of very and very high visible transparency,” said Stephen Forrest, the Peter A. Franken Distinguished University Professor of Engineering and Paul G. Goebel Professor of Engineering, who led the research.

Elon Musk’s Las Vegas Boring Company tunnels ‘only a few months away’ from operation

Posted by in categories: Elon Musk, sustainability, transportation

The Boring Company’s Las Vegas tunnel will be operational in “only a few months,” according to company frontman Elon Musk, who updated the project’s progress on August 28.

Musk, CEO of the Boring Company, set out to create a new source of transportation in high-traffic areas several years ago while living in Los Angeles. While LA has a private test tunnel in Hawthorne, California, near the Tesla Design Studio and SpaceX Headquarters, Musk wanted to expand upon the idea and move it to other cities.


Las Vegas needed a transportation solution to handle traffic on the Strip, where many of the visitors spend the majority of their time while visiting the Sin City. However, the Las Vegas Convention Center also desired an underground people mover, and the Boring Co. was more than happy to make a $52.5 million bid on the project, which was accepted.
