An American entrepreneur has developed the innovative "Kanso" hand towel that cleans itself to need significantly less washing than standard hand towels. The correspondingly lower water and electricity consumption makes the hand towel environmentally-friendly and cost efficient. The basic material consists of bamboo so that the hand towel is very soft and faster drying than a conventional towel. Polygenic silver ions are also worked into it to provide it with a cleaning effect. These can remove 99% of all bacteria and fungi, and are already used by companies such as Adidas and Patagonia.
Researchers at the California Institute of Technology have created the first battery based on fluoride that can be used at room temperature. This aims to make it possible for smartphones to require charging only once a week. In contrast to lithium, fluoride's high atomic mass allows it to create not positively but negatively charged ions to produce electricity and it thereby works more efficiently. The flow of ions at low temperatures is made possible through the use of a special electrolyte concentration.
