Can expert commissions develop solutions for controversial issues that will enjoy broad democratic support? Researchers from the IASS have analysed the work of Germany's "Coal Exit Commission" using a set of new criteria. While the authors view positively the Commission's success in reaching a compromise, they criticise its failure to deliver an outcome that promotes the common good, particularly with respect to high costs of the coal exit and its unambitious contribution towards climate goals.
New mechanisms for converting sunlight to electricity more efficiently are also beneficial for extending the lifespan of solar panels
A new system developed in the lab of Zhen (Jason) He uses bacteria to filter wastewater while creating electricity.
A new experiment shows that the more energy consumed by a clock, the more accurate its timekeeping. This is the first time that a measurement has been made of the entropy - or heat loss - generated by a minimal clock tens of nanometers thick and 1.5 millimeters long. Understanding the thermodynamic cost involved in timekeeping is a central step along the way in the development of future technologies, as systems approach the quantum realm.
Training the artificial intelligence models that underpin web search engines, power smart assistants and enable driverless cars, consumes megawatts of energy and generates worrying carbon dioxide emissions. But new ways of training these models are proven to be greener.
Researchers from Japan Advanced Institute of Science and Technology (JAIST) have successfully established a new humidity in situ measurements for anion conducting polymer thin films.
Induced bank filtration is a key and well-established approach to provide drinking water supply to populated areas located along rivers or lakes and with limited access to groundwater resources. It is employed in several countries worldwide, with notable examples in Europe, the United States, and parts of Africa. Contamination of surface waters poses a serious threat to attaining drinking water standards.
The introduction of lithium-ion (Li-ion) batteries has revolutionized technology as a whole, leading to major advances in consumer goods across nearly all sectors. Battery-powered devices have become ubiquitous across the world. While the availability of technology is generally a good thing, the rapid growth has led directly to several key ethical and environmental issues surrounding the use of Li-ion batteries.
The famed northern and southern lights have been studied for millennia, but they still hold secrets. In a new study, physicists led by the University of Iowa describe a new phenomenon they call "diffuse auroral erasers," in which patches of the background glow are blotted out, then suddenly intensify and reappear.
Solar-power developers need to explore using lower-quality agricultural land for solar energy, incentivize dual-use (combined agriculture and solar) options, avoid concentrated solar development and engage communities early to achieve New York's green energy goals, according to forthcoming Cornell University research.
