LUCIDGames: A technique to plan adaptive trajectories for autonomous vehicles

Posted by in categories: information science, robotics/AI, transportation

While many self-driving vehicles have achieved remarkable performance in simulations or initial trials, when tested on real streets, they are often unable to adapt their trajectories or movements based on those of other vehicles or agents in their surroundings. This is particularly true in situations that require a certain degree of negotiation, for instance, at intersections or on streets with multiple lanes.

Researchers at Stanford University recently created LUCIDGames, a that can predict and plan adaptive trajectories for autonomous vehicles. This technique, presented in a paper pre-published on arXiv, integrates an algorithm based on game theory and an estimation method.

New nanomaterial helps obtain hydrogen from a liquid energy carrier, in a key step toward a stable and clean fuel source

Posted by in categories: chemistry, economics, nanotechnology, particle physics, sustainability, transportation

Hydrogen is a sustainable source of clean energy that avoids toxic emissions and can add value to multiple sectors in the economy including transportation, power generation, metals manufacturing, among others. Technologies for storing and transporting hydrogen bridge the gap between sustainable energy production and fuel use, and therefore are an essential component of a viable hydrogen economy. But traditional means of storage and transportation are expensive and susceptible to contamination. As a result, researchers are searching for alternative techniques that are reliable, low-cost and simple. More-efficient hydrogen delivery systems would benefit many applications such as stationary power, portable power, and mobile vehicle industries.

Now, as reported in the journal Proceedings of the National Academy of Sciences, researchers have designed and synthesized an effective material for speeding up one of the limiting steps in extracting from alcohols. The material, a , is made from tiny clusters of nickel anchored on a 2-D substrate. The team led by researchers at Lawrence Berkeley National Laboratory’s (Berkeley Lab) Molecular Foundry found that the catalyst could cleanly and efficiently accelerate the reaction that removes hydrogen atoms from a liquid chemical carrier. The material is robust and made from earth-abundant metals rather than existing options made from precious metals, and will help make hydrogen a viable energy source for a wide range of applications.

“We present here not merely a catalyst with higher activity than other nickel catalysts that we tested, for an important renewable energy fuel, but also a broader strategy toward using affordable metals in a broad range of reactions,” said Jeff Urban, the Inorganic Nanostructures Facility director at the Molecular Foundry who led the work. The research is part of the Hydrogen Materials Advanced Research Consortium (HyMARC), a consortium funded by the U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy Hydrogen and Fuel Cell Technologies Office (EERE). Through this effort, five national laboratories work towards the goal to address the scientific gaps blocking the advancement of solid hydrogen storage materials. Outputs from this work will directly feed into EERE’s H2@Scale vision for affordable hydrogen production, storage, distribution and utilization across multiple sectors in the economy.

New engine capability accelerates advanced vehicle research

Posted by in categories: energy, transportation

In the quest for advanced vehicles with higher energy efficiency and ultra-low emissions, Oak Ridge National Laboratory researchers are accelerating a research engine that gives scientists and engineers an unprecedented view inside the atomic-level workings of combustion engines in real time.

The new capability is an engine built specifically to run inside a neutron beam line. This neutronic engine provides a unique sample environment that allows investigation of structural changes in new alloys designed for the environment of a high-temperature, advanced combustion engine operating in realistic conditions.

ORNL first unveiled the capability in 2017, when researchers successfully evaluated a small, prototype engine with a cylinder head cast from a new high-temperature aluminum-cerium alloy created at the lab. The experiment was the world’s first in which a running engine was analyzed by , using the VULCAN neutron diffractometer at the Department of Energy’s Spallation Neutron Source, or SNS, at ORNL.

China’s electric car strategy is starting to go global – and the U.S. is lagging behind

Posted by in categories: energy, policy, sustainability, transportation

It seems competition is increasing.


BEIJING – In a future driven by electric vehicles, China is poised to dominate if the U.S. does not transform its automobile industry in coming years.

While California-based Tesla captured popular attention for electric cars, national policy in Beijing encouraged the launch of several rivals in China, the world’s largest auto market. Already, sales of electric cars and other new energy vehicles hit a record in September in China. Even Tesla launched a factory there last year, and is planning to sell made-in-China cars to Europe.

New class of cobalt-free cathodes could enhance energy density of next-gen lithium-ion batteries

Posted by in categories: energy, sustainability, transportation

Oak Ridge National Laboratory researchers have developed a new family of cathodes with the potential to replace the costly cobalt-based cathodes typically found in today’s lithium-ion batteries that power electric vehicles and consumer electronics.

The new class called NFA, which stands for nickel-, iron-and aluminum-based cathode, is a derivative of lithium nickelate and can be used to make the positive electrode of a lithium-ion battery. These novel cathodes are designed to be fast charging, energy dense, cost effective, and longer lasting.

With the rise in the production of portable electronics and electric vehicles throughout the world, are in high demand. According to Ilias Belharouak, ORNL’s scientist leading the NFA research and development, more than 100 million electric vehicles are anticipated to be on the road by 2030. Cobalt is a metal currently needed for the cathode which makes up the significant portion of a lithium-ion battery’s cost.

R/C Car vs 550hp Lamborghini Gallardo LP 550–2

Posted by in category: transportation

We all know you thought about it and we’ve though about it. Now we are going to do it. RC vs Supercars is a new segment we started and hopefully takes off depending on the success of this video.

What’s more exciting than racing? We pitted the Lp550-2 against our Badass Mad Drift and let them loose on a 300+ feet runway.
