All-electric cars may be worse for environment

December 16, 2014 8:02 am | by Associated Press, Seth Borenstein | News | Comments

People who own all-electric cars where coal generates the power may think they are helping the environment. But a new study finds their vehicles actually make the air dirtier, worsening global warming. Ethanol isn't so green, either. The study examines environmental costs for cars' entire lifecycle, including where power comes from and the environmental effects of building batteries.

Small engine packs a punch

December 5, 2014 8:15 am | by Rob Matheson, MIT News Office | News | Comments

Noise, excessive vibration and relative inefficiency are drawbacks of the piston-based internal combustion engines (ICE) that power today’s lawn and garden equipment, such as leaf blowers and lawn trimmers. But now Massachusetts Institute of Technology startup LiquidPiston has developed a rotary ICE that it says is significantly smaller, lighter and quieter, as well as 20% more fuel-efficient than the ICEs used in small-engine devices.

Advancements in battery technology shaping the future of electronic vehicles

November 21, 2014 9:57 am | by Canadian Light Source | News | Comments

Scientists at the Canadian Light Source are on the forefront of battery technology using cheaper materials with higher energy and better recharging rates that make them ideal for electric vehicles (EVs). The switch from conventional internal combustion engines to EVs is well underway. However, limited mileage of current EVs due to the confined energy storage capability of available battery systems is why these vehicles aren't more common.

Could hydrogen vehicles take over as the “green” car of choice?

November 20, 2014 7:59 am | by American Chemical Society | News | Comments

Now that car makers have demonstrated through hybrid vehicle success that consumers want less-polluting tailpipes, they are shifting even greener. In 2015, Toyota will roll out the first hydrogen fuel-cell car for personal use that emits only water. An article in Chemical & Engineering Newsexplains how hydrogen could supplant hybrid and electric car technology.

Self-driving vehicles generate enthusiasm, concerns worldwide

October 31, 2014 8:22 am | by Bernie DeGroat, Univ. of Michigan | News | Comments

Despite safety concerns about equipment failure, a majority of drivers on three continents have high expectations for autonomous vehicles. Building on an earlier study on public opinion regarding self-driving vehicles in the U.S., Great Britain and Australia, a team from the Univ. of Michigan Transportation Research Institute expanded their survey to include more than 1,700 respondents in India, China and Japan.

Electric-car drivers trading gas for solar power

October 28, 2014 5:33 pm | by Dee-Ann Durbin, AP Auto Writer | News | Comments

Owners of electric vehicles have already gone gas-free. Now, a growing number are powering their cars with sunlight. Solar panels installed on the roof of a home or garage can easily generate enough electricity to power an electric or plug-in gas-electric hybrid vehicle. The approach is not cheap, but advocates say the investment pays off over time and is worth it for the thrill of fossil fuel-free driving.

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

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.
