Used cigarette butts offer energy storage solution

Scientists in South Korea have developed a new way to store energy that also offers a solution to a growing environmental problem.
 
Reporting their findings in the IOP Publishing journal Nanotechnology, the research team successfully converted used cigarette butts into a high performing material that could be integrated into computers, handheld devices, electric vehicles and wind turbines to store energy.
According to the study, this material outperforms commercially available carbon, graphene and carbon nanotubes. It may someday be used to coat the electrodes of supercapacitors: electrochemical components that can store extremely large amounts of electrical energy.
"Our study has shown that used cigarette filters can be transformed into a high performing carbon-based material using a simple one step process, which simultaneously offers a green solution for meeting the energy demands of society," says co-author Professor Jongheop Yi of Seoul National University.

Easy monitoring with weather sensors from Lufft

Professional weather sensors form the heart of large solar plants supporting their operation and performance. Lufft was the first manufacturer to combine several sensors in one housing, bringing the largest multiparameter weather sensor family with 19 members into being. Many of them are well-suited for solar site assessment and continuous monitoring. The most commonly used one is the WS600 delivering data on temperature, air pressure, wind, relative humidity and precipitation. Through its open protocol, it can easily be attached to radiation sensors e.g. from Kipp&Zonen. Other models have an integrated Silicon, Second Class or Secondary Standard radiation sensor.
