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.
Renewable energy sources are becoming increasingly important for the worldwide power mix. Nevertheless, experts are still deliberating which market model is best for transitioning to renewables. However, one of the major technological challenges in this regard, namely balancing the fluctuations that are caused by wind and solar power, may soon be solved.
Researchers are developing a methodology and framework to accurately calculate carbon emissions from supply chains. The approach considers user needs and the requirements of different stakeholders: producers, transporters, wholesalers and political bodies.
Some plastics can be recycled, but transparent film plastics are presently not considered worth reclaiming from landfill. An EU project aimed to change that, promoting flexible painted and laminated plastic film (commonly used for food, toys, cosmetics, and industrial parts) as a valuable recycling resource.
A fleet of 130 virtual electric cars is set to commence on the roads of Munich, Germany. A smartphone's software records and processes the driving data to reveal how electric vehicles would perform the corresponding operational cycles in environmental and economic terms.
