Blasting Rich People Into Space Is Better Business Than Uber, Somehow

Posted by in categories: business, transportation

Virgin Galactic is preparing to become the first publicly traded spaceflight company, and the venture is setting a course to be profitable by August 2021, which would put it lightyears ahead of the profitability projections of another transportation-based company that simply moves people around on Earth: Uber.

The Wall Street Journal reports that Virgin Galactic is merging with Social Capital Hedosophia Holdings (SCH), which will take a 49 percent stake and invest about $800 million into the space tourism endeavor.

Invention: Plasma-powered flying saucer

Posted by in categories: innovation, transportation

By Justin MullinsPass a current or magnetic field through a conducting fluid and it will generate a force. Numerous aerospace engineers have tried and failed to exploit this phenomenon, known as magnetohydrodynamics, as an exotic form of propulsion for aircraft. But perhaps attempts so far have all been too big.

A very small design could have a better chance of taking off, says Subrata Roy, an aerospace engineer at the University of Florida, Gainesville, US.

With a span of less than 15 centimetres, his aircraft qualifies as a micro air vehicle (MAV), but it has an unconventional design to say the least. It is a saucer shape covered with electrodes that ionise air to create a plasma. This plasma is then accelerated by an electric field to push air around and generate lift.

Antigravity water transport system inspired by trees

Posted by in categories: engineering, solar power, sustainability, transportation

Efficiently moving water upward against gravity is a major feat of human engineering, yet one that trees have mastered for hundreds of millions of years. In a new study, researchers have designed a tree-inspired water transport system that uses capillary forces to drive dirty water upward through a hierarchically structured aerogel, where it can then be converted into steam by solar energy to produce fresh, clean water.

The researchers, led by Aiping Liu at Zhejiang Sci-Tech University and Hao Bai at Zhejiang University, have published a paper on the new transport and solar steam generation method in a recent issue of ACS Nano. In the future, efficient water transport methods have in and desalination.

“Our preparation method is universal and can be industrialized,” Liu told Phys.org. “Our materials have excellent properties and good stability, and can be reused many times. This provides the possibility for large-scale desalination and in the future.”

Toyota to test solar panels for electric cars

Posted by in categories: sustainability, transportation

What’s not to like about this concept: high-efficiency solar cells gifting electric cars with mileage.

Bertel Schmitt, The Drive, said, “The solar roof could morph from mostly a marketing-device to a helpful feature.” He noted that, referring to plug-ins, “On a fair-weather day, the juice would be provided by the sun, a big improvement especially for people who don’t have their own garage.”

Toyota has ambitions over the concept and is to start testing an onboard solar recharging system where the hood, the roof, and back are covered with cells. The solar roof can charge while the car is on the move.

Demonstrations of DARPA’s Ground X-Vehicle Technologies

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

DARPA’s Ground X-Vehicle Technologies (GXV-T) program aims to improve mobility, survivability, safety, and effectiveness of future combat vehicles without piling on armor. The demonstrations featured here show progress on technologies for traveling quickly over varied terrain and improving situational awareness and ease of operation.

These demonstrations feature technologies developed for DARPA by:

Elon Musk and the electric (VTOL supersonic jet) plane that could

Posted by in categories: Elon Musk, transportation

Elon Musk is a lot of things to a lot of people, but there’s something very interesting about him that drives most others: If he thinks something is worth improving, there’s more than a coin’s toss of a chance he’s going to make a go of it.

Now, Musk is a fantastically creative guy and all, but I’m not here to shower him with accolades (today anyhow). I’m setting the stage to discuss the next so-called improbable thing he might take on in the near future.

“I have an idea for a vertical takeoff and landing supersonic jet.”

China’s Big AI Advantage: Humans

Posted by in categories: economics, education, government, robotics/AI, transportation

Seemingly “intelligent” devices like self-driving trucks aren’t actually all that intelligent. In order to avoid plowing into other cars or making illegal lane changes, they need a lot of help.

In China, that help is increasingly coming from rooms full of college students.

Airspeeder series to debut 120-mph, head-to-head, manned multicopter racing in 2020

Posted by in category: transportation

A grid full of 10 giant coaxial octocopters, each with a pilot on board, racing each other head-to-head through the air at speeds up to 200 km/h (120 mph)? That’s exactly what the Airspeeder racing series is set to introduce in 2020 with the aim of being a kind of Formula One for flying cars.
