U.S. Navy Tests Unmanned Underwater Vehicles Powered by Hydrogen Fuel Cells
The Navy's large-displacement UUV is a new class of undersea vessels designed to conduct intelligence, surveillance and mine countermeasure missions of longer than 70 days.
Graphene Device Can Convert Cars' Waste Heat to Electricity
The advantage of a graphene-based nano-rectifier is its high conversion efficiency from an alternating current to a direct current at room temperature.
Self-Driving Bus Taps Power of IBM Watson
Olli utilizes the computing capability of IBM Watson Internet of Things to analyze and learn from high volumes of transportation data produced by more than 30 embedded sensors.
Tesla Considers a Commercial-grade Pickup
According to CEO Elon Musk, Telsa may be on the brink of developing a commercial-grade pickup meant to rival Ford’s popular F-150.
New Molecular Design to Get Hydrogen-Powered Cars Motoring
Using formic acid to produce hydrogen traditionally has not been considered viable because it requires high temperatures to decompose and produces waste byproducts.
Damage to Highways from Heavy Trucks Assessed
The findings will be incorporated into software that can be used by any road agency in the country to assess the impact of super-heavy loads on pavements.
Improved Aerodynamics Helps Volvo Big Rig to 30% Fuel Reduction
The Volvo Concept Truck uses a 40% improvement in aerodynamic efficiency to the tractor and trailer to achieve the fuel savings.
Video: Drones may be stopped by technology being tested at U.S. airports. Big Apple gardens may help manage stormwater runoff. Trucks use waste heat to help power them.
Drones may be stopped by technology being tested at U.S. airports. The Big Apple plants gardens to help manage stormwater runoff. And trucks use their waste heat to help power them along roadways.
Aluminum-Cerium Alloys Could Boost Engine Efficiency and Rare Earth Production
Rare earths are a group of elements critical to electronics, alternative energy and other modern technologies. Yet there is no production occurring in North America at this time.
Dual-Fuel Garbage Trucks to Showcase Hydrogen's Transport Potential
The trucks, converted to run on hydrogen and diesel, are expected to reduce carbon emissions and improve air quality in densely populated urban areas.
Truck Reuses Engine Heat for Power
According to KTH, the system could save vehicles hundreds of liters of fuel and reduce their carbon emissions by as much as 2 to 3 metric tons per year.
Laser Surface Preparation Yields Superior Joining of Composites, Aluminum
The team found that using a laser to remove layers of material from surfaces prior to bonding improves the performance of the joints and provides a path toward automation for high-volume use.
Ford Tests CO2-Based Foams
Use of captured carbon in place of petroleum as a plastic foam feedstock potentially helps reduce CO2 in two ways.
ORNL Team Bonds CFC and Aluminum with Lasers
The technique uses a laser to prepare the surfaces for a bond that the researchers say is less expensive and that may yield stronger automotive joints.
Toward Greener Urban Transport
Increasing traffic congestion and escalating air pollution globally are leading to schemes for encouraging the wider use of public transport.
Roadside Sensors Could Cut Salting Costs
The sensors utilize WiFi networks to transmit data on road-surface temperatures to local authorities and highways agencies that use it to target precisely where salt is needed.
A City Car for the Masses
The total through-life costs for a production equivalent of the vehicle would be 34% less than for a typical “city car.”
Trams to Carry Collision Avoidance, Auto-Braking Tech
The system combines radar and video sensor technologies derived from Bosch's automotive division together with a rail control unit.
