Get ready for all-electric flying car races, they’re coming

Posted by in categories: economics, transportation

The Airspeeder vehicle, which weighs about 550 pounds, uses a battery pack that can be swapped out during the race. The packs are expected to last for about 15 minutes. Four 32-horsepower electric motors propel the cars to a top speed of about 125 miles per hour. The vehicle tears through the air between about 15 and 130 feet off the ground.

Matt Pearson, founder of Alauda and the Airspeeder series, said:

This Car Is Powered By Salt Water: 760HP, Top Speed 186 MPH, 621 Miles/Tank

Posted by in category: transportation

German company Nanoflow Cell unveiled a sleek looking fully electric Quant 48Volt at the Geneva Motor Show this year with the goal of the company bringing the first production car in the world to be powered by saltwater. The Quant 48Volt has two tanks of liquid with dissolved metallic salt which gives them opposite charges. The liquid is separated by a membrane where positively charged ions lose an electron generating electricity.

One fill up of the tanks are good for 621 miles (1,000 km) which astonishingly is greater distance our gasoline vehicles can take us. However, to fill up the tank which has the 3x capacity of large SUV will take quite a bit of time but certainly not hours.

The salt water powered vehicle generates 560kW (760HP) and goes 0-60mph in 2.4 seconds.

Elon Musk reveals the reason behind Tesla’s cabin-facing camera

Posted by in categories: Elon Musk, sustainability, transportation

Elon Musk has revealed the reason behind Tesla’s cabin-facing camera that has been in the Model 3 for years without being used.

When Tesla launched the Model 3, it equipped the vehicle with a standard cabin-facing camera located in the rearview mirror.

Using artificial intelligence to search for new exotic particles

Posted by in categories: entertainment, information science, mathematics, particle physics, robotics/AI, transportation

Nowadays, artificial neural networks have an impact on many areas of our day-to-day lives. They are used for a wide variety of complex tasks, such as driving cars, performing speech recognition (for example, Siri, Cortana, Alexa), suggesting shopping items and trends, or improving visual effects in movies (e.g., animated characters such as Thanos from the movie Infinity War by Marvel).

Traditionally, algorithms are handcrafted to solve complex tasks. This requires experts to spend a significant amount of time to identify the optimal strategies for various situations. Artificial neural networks — inspired by interconnected neurons in the brain — can automatically learn from data a close-to-optimal solution for the given objective. Often, the automated learning or “training” required to obtain these solutions is “supervised” through the use of supplementary information provided by an expert. Other approaches are “unsupervised” and can identify patterns in the data. The mathematical theory behind artificial neural networks has evolved over several decades, yet only recently have we developed our understanding of how to train them efficiently. The required calculations are very similar to those performed by standard video graphics cards (that contain a graphics processing unit or GPU) when rendering three-dimensional scenes in video games.

National Space Society Recommends More Commercial Emphasis in House NASA Authorization Act of 2020

Posted by in categories: economics, sustainability, transportation

The National Space Society (NSS) recognizes and supports all activities that help to enable commercial space development and settlement. Unfortunately, H.R. 5666 represents a dramatic step back from such activities.

NSS agrees with the Commercial Spaceflight Federation that the bill could incur large additional costs for NASA by eliminating commercial participation and competition in key programs. For example, the bill eliminates commercial options for lunar lander operations while inappropriately dictating to NASA a particular technical design. Additionally, the bill de-prioritizes efforts to build a base on the Moon, enable commercial lunar operations, or use ample lunar resources to dramatically lower the cost of going to Mars. Overall, the bill contains many technical specifications and requirements that are best left to NASA engineers and scientists.

We would strongly encourage the House Science, Space, and Technology Committee to reconsider this bill and build on the successful model of development programs, such as Commercial Orbital Transportation Services and Commercial Crew. We also strongly urge support for the Commercial Lunar Payload Services program based on the same model. These programs effectively harness commercial participation, save taxpayer dollars, and support the development of a sustainable space economy.

Charting a course toward quantum simulations of nuclear physics

Posted by in categories: computing, cosmology, particle physics, quantum physics, transportation

In nuclear physics, like much of science, detailed theories alone aren’t always enough to unlock solid predictions. There are often too many pieces, interacting in complex ways, for researchers to follow the logic of a theory through to its end. It’s one reason there are still so many mysteries in nature, including how the universe’s basic building blocks coalesce and form stars and galaxies. The same is true in high-energy experiments, in which particles like protons smash together at incredible speeds to create extreme conditions similar to those just after the Big Bang.

Fortunately, scientists can often wield simulations to cut through the intricacies. A represents the important aspects of one system—such as a plane, a town’s traffic flow or an atom—as part of another, more accessible system (like a or a scale model). Researchers have used their creativity to make simulations cheaper, quicker or easier to work with than the formidable subjects they investigate—like proton collisions or black holes.

Simulations go beyond a matter of convenience; they are essential for tackling cases that are both too difficult to directly observe in experiments and too complex for scientists to tease out every logical conclusion from basic principles. Diverse research breakthroughs—from modeling the complex interactions of the molecules behind life to predicting the experimental signatures that ultimately allowed the identification of the Higgs boson—have resulted from the ingenious use of simulations.
