Emissions Control

The International DuraStar at the Hybrid Truck Users Forum in South Bend, Ind.

With the spiraling cost of fuel and the average cost of diesel in 2008 climbing around 39 percent versus last year, it’s no surprise that truck manufacturers are looking to lighten the burden on trucking operators. To this end Navistar, makers of the LoneStar, has expanded its line of diesel electric hybrid trucks with the unveiling of their International DuraStar Hybrid tractor at this week’s Hybrid Truck Users Forum in South Bend, Indiana. Navistar claims that the new diesel electric hybrid Class 7 tractor has the proven capability to provide fuel savings of 20-25 percent on standard in-city pickup and delivery applications.  Read More

Proterra's HFC35 hybrid-electric bus

Proterra is presenting a prototype of its HFC35 composite body, hybrid-electric bus at the American Public Transportation Association expo in San Diego. Scheduled to start service in early 2009 in a nationwide trial, the 37-seat HFC35 contains a fuel cell hybrid-electric powertrain that emits only water, qualifying the bus as a zero-emission vehicle. However, it can also incorporate diesel, gasoline, and compressed natural gas engines.  Read More

Planning ahead: US electricity generation sources

While the current Wall Street financial crisis has many on edge in regard to the short term future of the economy, Google has displayed some far-sighted corporate leadership in releasing its plan for how to reduce fossil fuel use by 2030. "Clean Energy 2030" is designed to stimulate debate on a range of energy consumption issues and includes proposals to slash vehicle oil consumption and CO2 emissions by 38% and reduce US reliance on fossil fuel-based electricity generation by 88% through a significant boost to solar, wind and geothermal output. Importantly, the report also focusses on the "win-win" potential for this aggressive attack on climate change, citing a figure of $1.0 trillion net savings over the 22-year life of the plan.  Read More

Renault's all-electric Z.E. Concept Car

Renault has taken a holistic approach to energy saving with its latest concept car. Based on the new Kangoo be bop, the Z.E. (Zero Emission) Concept incorporates a number of innovations across all aspects of the vehicle to ensure optimum range is achieved from the lithium-ion battery powered 70kW (95hp) electric motor. These include the use of heat-reflective paint, acid green-tinted glass and air-insulated body panels designed to reduce reliance on energy-sapping climate control systems, along with roof-mounted solar panels, extensive use of LEDs and aerodynamic enhancements like the replacement of drag-producing exterior mirrors with low-energy cameras. There's also an on-board electric scooter that uses the car's charging system and provides an even greener option for short city trips.  Read More

The Volvo 7700 Hybrid system

In addition to reducing the discharge of particles and nitrous oxides by 40-50% compared with a diesel-only bus, the Volvo 7700 Hybrid has 30% lower fuel consumption which the company estimates will allow bus operators to recoup the extra cost of the vehicle within seven years.  Read More

GEM Peapod set for 2009 production

A decade after its launch and with 38,000 zero-emission electric vehicles produced and in use, Chrysler LLC's GEM brand has launched the first of its next-generation designs - the Peapod. Scheduled for production in 2009, the low-speed neighborhood commuter can cover up to 30 miles without recharging at a top speed of 25 mph. In keeping with the company's "lots of love" slogan, the new fully-enclosed pod design uses eco-friendly recycled and recyclable materials in its construction and should keep a lid on road rage by virtue of its smiling facade (both front and rear), as well as keeping those inside the car happy with new ergonomic mesh seating and a freshly designed center console featuring iPod integration and hands-free iPhone support.  Read More

In photosynthesis, protons and electrons would be converted to carbohydrates for the plant...

An international team of researchers led by Monash University has used manganese, a chemical involved in photosynthesis, to split water into hydrogen and oxygen using only sunlight and an electrical potential of 1.2 volts. Scientists claim the process could provide a clean, cheap method of producing hydrogen for fuel cells and energy generation.  Read More

Carbon Capture and Storage slashes CO2 emissions into the atmosphere, but requires an incr...

Carbon capture and storage is a climate change mitigation technology characterized by sporadic and unreliable government support and plagued with accusations that it will worsen the environmental disaster it seeks to address. Yet, despite the negative stigma, CCS has been labeled by the IPCC and the Stern Report as an essential measure in reducing the impact of fossil fuels. Gizmag's Kyle Sherer takes a closer look.  Read More

The unnamed 110cc prototype

August 8, 2008 Fuel injection arrived on two wheels with the release of Honda’s CX500 Turbo a quarter of a century ago, and Honda has been developing smarter and more intricate computer controlled fuel injection systems for its two wheelers ever since. These days its advanced PGM-FI (Programmed Fuel Injection) technology is fitted across the range from 50cc scooters through its MotoGP race machinery, offering broader and smoother power, better throttle response and vastly reduced fuel consumption and emissions. A prototype being quietly shown around Asia suggests that it might also lead to some lightning fast scooters in the near future.  Read More

Nissan ECO pedal meter

With rising petrol prices and a focus on climate change, the automotive industry is looking to pioneer new methods of fuel consumption, both in terms of developing new propulsion systems and making existing technology more efficient. News on the latter approach comes from Nissan, which has unveiled technology designed to help drivers use less fuel by using an "eco-pedal" system that resists excess pressure being applied to the accelerator.  Read More
