Black carbon is an air pollutant which harms human health and can contribute to climate change - so cutting emissions may have many benefits. The European Environment Agency (EEA) has published a report on the measurement of black carbon in the air.
An innovative new three-year research project will see the aquaculture, agriculture and biogas sectors working together to develop renewable energy. The initiative demonstrates how improving sustainability, reducing waste and achieving operational efficiencies can be achieved simultaneously.
Half-Heusler compounds are especially suited for manufacturing thermoelectric modules. Waste heat can be converted to electricity with them. Researchers have manufactured the alloys for the first time in kilogram quantities.
Loofahs, best known for their use in exfoliating skin to soft, radiant perfection, have emerged as a new potential tool to advance sustainability efforts on two fronts at the same time: energy and waste. A new study describes the pairing of loofahs with bacteria to create a power-generating microbial fuel cell.
Through a process known as thermionic conversion, heat energy can be converted into electricity with very high efficiency. Because of its promise, researchers have been trying for more than half a century to develop a practical thermionic generator, with little luck. That luck may soon change, thanks to a new design, dubbed a thermoelectronic generator.
