Sandia Labs harnessing the sun's energy with tiny particles

Engineers at Sandia National Laboratories, along with partner institutions Georgia Tech, Bucknell University, King Saud University and the German Aerospace Center (DLR), are using a falling particle receiver to more efficiently convert the sun's energy to electricity in large-scale, concentrating solar power plants.

Environmentally friendly cement is stronger than ordinary cement

New research from the Niels Bohr Institute shows that cement made with waste ash from sugar production is stronger than ordinary cement. The research shows that the ash helps to bind water in the cement so that it is stronger, can withstand higher pressure and crumbles less. At the same time, energy is saved and pollution from cement production is reduced.

Reusable materials from metallurgical plant dumps reduces imports of raw material

Metallurgical plant dumps harbor important raw materials such as metals and minerals that often have not been used yet. The reason: comprehensive data regarding the exact reusable material potential of these dumps is missing. To close this gap, Fraunhofer UMSICHT is coordinating the REStrateGIS project. The objective is to develop a multi-scalar resource register for metallurgical plant dumps.

Tiny plankton could have big impact on climate

As the climate changes and oceans' acidity increases, tiny plankton seem set to succeed. An international team of marine scientists has found that the smallest plankton groups thrive under elevated carbon dioxide levels. This could cause an imbalance in the food web as well as decrease ocean CO2 uptake, an important regulator of global climate.

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.
