Technology and Software from Siemens are making the world's largest container ships more energy-efficient. The Korean shipbuilding company Daewoo is building 20 container ships for the Danish shipping...
View ArticleAmazing engines promise 60 to 100 mpg
It would be a mistake to count out the internal-combustion engine as yesterday's technology, soon to expire in a puff of exhaust gas. Electrification is coming, but meanwhile engineers have offered...
View ArticleAir pollution study clears the air on diesel versus gas emissions
(Phys.org)—Are gasoline-fueled cars or large diesel trucks the bigger source of secondary organic aerosol (SOA), a major component of smog? UC Berkeley researchers have stepped into this debate with a...
View ArticleWhen pollution gets a whiff of trees: City and tree emissions mix it up...
It's easy to visualize particles and gases from vehicle exhaust or burning trash wafting into the atmosphere. It's harder to envision similar gases and minute particles emitted from trees and plants in...
View ArticleOrganic vapors affect clouds leading to previously unidentified climate cooling
University of Manchester scientists, writing in the journal Nature Geoscience, have shown that natural emissions and manmade pollutants can both have an unexpected cooling effect on the world's climate...
