Why drop in oil prices has downside for U.S. economy

October 13, 2014 4:38 pm | by Jonathan Fahey - AP Energy Writer - Associated Press | News | Comments

Low oil prices sure feel nice. But there are downsides to the recent plunge in oil prices. Low fuel prices can help boost economic growth by reducing fuel bills and leaving consumers and companies with more money to spend on other things. Problem is, two factors behind the oil-price drop—a weaker global economy and a stronger dollar—could hurt the U.S. economy by reducing exports, employment and spending.

World's first bullet train, made in Japan, turns 50

October 1, 2014 10:23 am | by Emily Wang and Ken Moritsugu, Associated Press | News | Comments

It was, retired Japanese railway engineer Fumihiro Araki recalls, "like flying in the sky." Zipping cross-country in a super-high-speed train has become commonplace in many countries these days, but it was unheard of when Japan launched its bullet train between Tokyo and Osaka 50 years ago Wednesday.

New algorithms lets owners swap, recharge battery modules in electric cars

September 17, 2014 1:51 pm | News | Comments

Imagine being able to switch out the batteries in electric cars just like you switch out batteries in a photo camera or flashlight. Engineers in California are trying to accomplish just that, in partnership with a local San Diego engineering company. Rather than swapping out the whole battery, which is cumbersome and requires large, heavy equipment, engineers plan to swap out and recharge smaller units within the battery, known as modules.

Manufactures of turbine engines for airplanes, automobiles and electric generation plants could expedite the development of more durable, energy-efficient turbine blades thanks to a partnership between Argonne National Laboratory, the German Aerospace Center and the universities of Central Florida and Cleveland State. The ability to operate turbine blades at higher temperatures improves efficiency and reduces energy costs.

Nanotechnology to provide cleaner diesel engines

September 9, 2014 8:32 am | by Bertel Henning Jensen, Technical Univ. of Denmark | News | Comments

When it comes to diesel engine catalysts, which are responsible for cleansing exhaust fumes, platinum has unfortunately proved to be the only viable option. This has resulted in material costs alone accounting for half of the price of a diesel catalyst. Researchers in Denmark say they have developed a new way to manufacture catalysts that may result in a 25% reduction in the use of platinum.

Tesla selects Nevada for battery plant

September 4, 2014 8:55 am | by Justin Pritchard and Scott Sonner, Associated Press | News | Comments

Coming to Nevada's high desert: A massive, $5 billion factory that will pump out high-tech batteries for hundreds of thousands of electric vehicles. That's assuming state leaders deliver on the economic incentives they packaged to entice Tesla Motors to Nevada rather than four other states competing for the factory and the economic jolt it promises to bring.

NIST develops prototype meter test for hydrogen refueling stations

July 22, 2014 2:20 pm | News | Comments

Three automakers plan to begin selling hydrogen-fueled vehicles to consumers in 2015. To support the fair sale of gaseous hydrogen as a vehicle fuel, researchers at NIST have developed a prototype field test standard to test the accuracy of hydrogen fuel dispensers. Once the standard is field tested, it will serve as a model for constructing similar devices for state weights and measures inspectors to use.

What makes cities in India and China so frustrating to drive in makes them ideal for saving fuel with hybrid vehicles, according to new research by scientists at Lawrence Berkeley National Laboratory. Heavy traffic, aggressive driving style and few freeways allow hybrids in these countries to deliver as much as a 50% increase in fuel savings over conventional internal combustion vehicles.

Driving down fuel usage

March 10, 2014 10:57 am | by Rob Matheson, MIT News Office | News | Comments

Despite their potential to reduce carbon dioxide emissions and fuel consumption, electric and hybrid cars and trucks struggled for years to find a solid customer base. Much of the reason came down to cost and convenience: Electric car batteries are expensive, and charging them requires plug-in infrastructure that’s still sparse in the U.S.
