Project: Next-generation internal-combustion engine
Principal institutions: General Motors/University of Michigan Collaborative Research Laboratories
New technology combining elements of spark ignition and diesel engines promises to be 15 percent more fuel-efficient than conventional gas engines.
Project: Active traffic Management
Principal institutions: U.S. Department of Transportation
Wireless communication between vehicles and roadway infrastructure could reduce congestion by providing real-time information to drivers and traffic managers.
Project: Carbon-nanotube ultracapacitors
Principal institutions: MIT
Advanced ultracapacitors for hybrid and electric cars would charge and discharge much faster than batteries.
Project: National Bus Rapid Transit Institute
Principal institutions: University of South Florida
Is working to combine buses with intelligent transportation technologies to create systems that can substitute for light rail or subways in cities.
Project: Aviation biofuels
Principal institutions: Boeing
Different biofuels are being tested for use in commercial jets.
Project: The Civitas Initiative
Principal institutions: European Commission
Is developing integrated technological and policy-based approaches to energy-efficient transportation in cities.
Project: Lithium-air batteries
Principal institutions: IBM
Technology that could store 10 times as much energy as conventional lithium batteries.
Project: Next-generation train
Principal institutions: German Aerospace Center
This new system would use half as much energy as other high-speed trains and be 25 percent faster.
Project: Energy Biosciences Institute
Principal institutions: University of California, Berkeley; Lawrence Berkeley National Laboratory; University of Illinois; BP
Plans to develop biofuels using synthetic biology.
Principal institutions: U.S. Air Force, Boeing
The first demonstration of an unmanned military space plane will take place in January 2010. In theory, a space plane could take passengers from London to Sydney in four to five hours.

China’s losing its taste for nuclear power. That’s bad news.
Once nuclear’s strongest booster, China is growing wary about its cost and safety.
The record for high-temperature superconductivity has been smashed again
Chemists found a material that can display superconducting behavior at a temperature warmer than it currently is at the North Pole. The work brings room-temperature superconductivity tantalizingly close.
Climate change’s highest cost: Overheated employees too miserable to work
The US economy could lose $221 billion annually by 2090 as people stop working as much or as hard.
