Surrey study investigates effect of group cycling on exposure to pollutants

Green Car Congress

In an open access paper in the Journal of Wind Engineering and Industrial Aerodynamics , researchers at the University of Surrey (UK) have investigated the effect of group riding on cyclists’ exposure to vehicle pollutants. With more wind, riding towards the back of the group can be a good strategy to minimize exposure.

Stanford study finds current carbon capture technology inefficient & increases air pollution

Green Car Congress

Jacobson, professor of civil and environmental engineering at Stanford University, suggests that carbon capture technologies are inefficient and increase air pollution. However, this research finds that it reduces only a small fraction of carbon emissions, and it usually increases air pollution. A study by Mark Z.

Study links PM2.5 pollution with millions of preterm births globally

Green Car Congress

Recent research has suggested that exposure to air pollution could also be a risk factor. exposures, inclusion of provider-initiated preterm births, and exposure to indoor air pollution. There are many known risk factors for preterm birth—from the mother’s age, to illness, to poverty and other social factors. Malley et al.

Odfjell first to install suction sails on deep-sea chemical tanker; bound4blue’s eSAIL system

Green Car Congress

In partnership with bound4blue , a developer of wind-assisted propulsion technology, Odfjell. The eSAIL is a type of Wind-Assisted Propulsion System (WAPS) based on active boundary layer control using suction. When exposed to wind, with the suction off, it only produces drag as with any other non-lifting structure.

WUSTL study finds use of air conditioning reduces in-car pollution

Green Car Congress

Traffic is a major source of harmful pollutants; daily peak exposures tend to occur near roadways or while traveling—or being stuck—on them. That gave them rare, real-world look at pollutant exposure. With windows closed, the pollutants took longer to enter the vehicle cabin, but also longer to exit it. the least.

DOE awards $35M to 12 ARPA-E projects to reduce methane emissions; 5 on natural gas engines

Green Car Congress

The following teams selected for the REMEDY program will work to directly address the more than 50,000 engines, 300,000 flares, and 250 mine shafts that are producing methane emissions. Natural Gas Engines. This would simultaneously reduce methane emissions and improve engine efficiency. Selection amount: $1,500,000).

Study links air pollution and cyclone intensity in Arabian Sea; suggested solutions include diesel filters and two-stroke engines running on LPG fuel

Green Car Congress

Pollution is making Arabian Sea cyclones more intense, according to a study in the journal Nature. Historically, prevailing wind shear patterns prohibit cyclones in the Arabian Sea from becoming major storms. Gonu produced category 5-strength winds in excess of 250 kilometers per hour (156 miles per hour).
