Innovative hybrid diesel engine developed to run on natural gas (w/video)

Researchers at ETH Zurich have developed an internal combustion engine that emits less than half the CO2 compared to a regular engine without compromising performance. This corresponds to fuel consumption of less than 2.4l per 100km. This natural gas-diesel hybrid engine is based on a system of sophisticated control engineering.

Cilantro, that favorite salsa ingredient, purifies drinking water

Reporting on research done by undergraduate students at a community college, Douglas Schauer, Ph.D., said that cilantro - also known as coriander and Thai parsley - shows promise as a much-needed new 'biosorbent' for removing lead and other potentially toxic heavy metals from contaminated water.

Delaying climate policy would triple short-term mitigation costs

Further delay in the implementation of comprehensive international climate policies could substantially increase the short-term costs of climate change mitigation. Global economic growth would be cut back by up to 7 percent within the first decade after climate policy implementation if the current international stalemate is continued until 2030 - compared to 2 percent if a climate agreement is reached by 2015 already, a study to be published next Tuesday by scientists of the Potsdam Institute for Climate Impact Research (PIK) shows.

Gas flaring and household stoves speed Arctic thaw

Gas flaring by the oil industry and smoke from residential burning contributes more black carbon pollution to Arctic than previously thought - potentially speeding the melting of Arctic sea ice and contributing to the fast rate of warming in the region.

Coffee grounds could be a promising energy resource for the future

For many of us, it's the fuel that wakes us up and gets us started on our day. Now, University of Cincinnati researchers are discovering that an ingredient in our old coffee grounds might someday serve as a cheaper, cleaner fuel for our cars, furnaces and other energy sources.

The new allure of electric cars: Blazing-fast speeds

Already noted for saving gasoline and having zero emissions, electric cars have quietly taken on an unlikely new dimension - the ability to reach blazing speeds that rival the 0-to-60 performance of a typical Porsche or BMW, and compete on some race courses with the world's best gasoline-powered cars, an authority said here today at a major scientific conference.

Scientists calculate the energy required to store wind and solar power on the grid

Renewable energy holds the promise of reducing carbon dioxide emissions. But there are times when solar and wind farms generate more electricity than is needed by consumers. Storing that surplus energy in batteries for later use seems like an obvious solution. But a new Stanford University study finds that when you factor in the energetic costs, grid-scale batteries make sense for storing surplus solar energy, but not for wind.
