Hydrogen power is gaining momentum, but critics say it’s neither efficient nor green enough

Posted by in categories: chemistry, energy

Hydrogen is already a key component of chemical industrial processes and in the steel industry. So making clean hydrogen to use in those industrial processes is critical to reducing carbon emissions, says Jake Stones at market research firm Independent Commodity Intelligence Services (ICIS).

But as an energy source itself, hydrogen’s big advantage is its versatility according to Sunita Satyapal, who oversees hydrogen fuel cell technology for the Department of Energy.

“It’s often called the Swiss Army knife of energy,” she says.

High-Speed Train Builder Wins Appeal Over Land Use

Posted by in categories: law, transportation

(TNS) — The legal tug-of-war over development of waterfront land in Baltimore’s Westport neighborhood has tilted in favor of a high-speed maglev train operator seeking to build a passenger station on the site where a developer separately proposed housing.

The Court of Special Appeals, the state’s second-highest court, granted the appeal of Baltimore Washington Rapid Rail LLC, which is planning a $10 billion project to link Washington and Baltimore and eventually New York with a superconducting magnetic levitation rail system.

The opinion clears the way for Rapid Rail to pursue its eminent domain lawsuit against Westport property owner Stonewall Capital, prolonging a monthslong dispute.

How Changes in the Neural Code Unlock the Brain’s Inner Learning

Posted by in category: neuroscience

Summary: Findings shed light on how plastic and stable neural populations are able to co-exist in the brain.

Our brains are highly skilled at learning patterns in the world and making sense of them. The brain continually learns and adapts throughout our lives, and even the neurons supporting learned behaviors, such as the daily walk to work, are constantly changing.

U.S. eliminates human controls requirement for fully automated vehicles

Posted by in categories: robotics/AI, transportation

WASHINGTON, March 10 (Reuters) — U.S. regulators on Thursday issued final rules eliminating the need for automated vehicle manufacturers to equip fully autonomous vehicles with manual driving controls to meet crash standards.

Automakers and tech companies have faced significant hurdles to deploying automated driving system (ADS) vehicles without human controls because of safety standards written decades ago that assume people are in control.

Last month, General Motors Co (GM.N) and its self-driving technology unit Cruise petitioned the U.S. National Highway Traffic Safety Administration (NHTSA) for permission to build and deploy a self-driving vehicle without human controls like steering wheels or brake pedals.

Amazon and Virginia Tech launch AI and ML research initiative

Posted by in categories: information science, robotics/AI

Amazon and Virginia Tech today announced the establishment of the Amazon – Virginia Tech Initiative for Efficient and Robust Machine Learning.

The initiative will provide an opportunity for doctoral students in the College of Engineering who are conducting AI and ML research to apply for Amazon fellowships, and it will support research efforts led by Virginia Tech faculty members. Under the initiative, Virginia Tech will host an annual public research symposium to share knowledge with the machine learning and related research communities. And in collaboration with Amazon, Virginia Tech will co-host two annual workshops, and training and recruiting events for Virginia Tech students.

“This initiative’s emphasis will be on efficient and robust machine learning, such as ensuring algorithms and models are resistant to errors and adversaries,” said Naren Ramakrishnan, the director of the Sanghani Center and the Thomas L. Phillips Professor of Engineering. “We’re pleased to continue our work with Amazon and expand machine learning research capabilities that could address worldwide industry-focused problems.”

Army Special Operations Forces use Project Origin systems in latest Soldier experiment

Posted by in categories: robotics/AI, transportation

DUGWAY, Utah — Army Green Berets from the 1st Special Forces Group conducted two weeks of hands-on experimentation with Project Origin Unmanned Systems at Dugway Proving Ground. Engineers from the U.S. Army DEVCOM Ground Vehicle Systems Center were on site to collect data on how these elite Soldiers utilized the systems and what technology and behaviors are desired.

Project Origin vehicles are the evolution of multiple Soldier Operational Experiments. This GVSC-led rapid prototyping effort allows the Army to conduct technology and autonomous behavior integration for follow-on assessments with Soldiers in order to better understand what Soldiers need from unmanned systems.

For the two-week experiment, Soldiers with the 1st Special Forces Group attended familiarization and new equipment training in order to develop Standard Operating Procedures for Robotic Combat Vehicles. The unit utilized these SOPs to conduct numerous mission-oriented exercises including multiple live-fire missions during the day and night.
