Researchers are questioning the received wisdom regarding the promotion of electric vehicles in towns and cities. They suggest that the evidence of benefits in terms of energy usage and emissions points to electric vehicle use in sub-urban and rural settings as being much stronger.
In the race to secure clean energy in the future, engineers are reinventing a piece of technology which has so far only been used in labs to diagnose cancer, detect explosives, and even analyse grand artistic masterpieces.
It has been known for several years that sulfuric acid contributes to the formation of tiny aerosol particles, which play an important role in the formation of clouds. A new study shows that dimethylamine can tremendously enhance new particle formation. The formation of neutral nucleating clusters of sulfuric acid and dimethylamine was observed for the first time.
New tools will merge urban design with scientific analysis to improve the decision-making process associated with large-scale urban developments. One such tool, called LakeSim, has been prototyped with an initial focus on consumer-driven energy and transportation demand.
A new online meter combines a live data feed drawing on European data, updated regularly to show the precise level of CO2 in the earth's atmosphere today, and comparison tools to show how CO2 levels have changed over time.
Some 380 million tonnes of construction and demolition waste are generated every year and most of it ends up in landfills. Re-using and recycling components and materials is good for the environment and saves money, but industry has been less than enthusiastic. An EU-funded research project has laid the foundations for change - it is promoting concrete, ceramics, gypsum and plastics recycling around Europe.
This innovative engine integrates the traditional electric motor with the air-con compressor, typically two separate units. This novel, space-saving design allows the use of bigger batteries, which can increase the range of electric vehicles by an additional 15 to 20 per cent.
