Tracking down the whale-shark highway

Abuja, african inspired, BLOGS, BUSINESS, IkaTv, Innovation, Innovation Africa, wazobia companies, Youths
Did you know that August 30 was International Whale Shark Day? Whale sharks are the largest fishes on Earth, growing up to 18 meters (60 feet) long, but they feed mostly on tiny drifting animals such as copepods and, occasionally, small fish such as anchovies. To satisfy their immense appetites, whale sharks travel long distances to find dense swarms of prey.MBARI biological oceanographer John Ryan recently worked with biologists who have been tracking whale sharks in the Eastern Tropical Pacific Ocean. They...Powered by WPeMatico

New device could turn heat energy into a viable fuel source

By monitoring the optical response of an externally probed laser cavity before and after gain clamping, a University of Central Florida and Yale collaboration reveals the underlying mechanisms driving the cavity's responsesSince the realization of the first laser cavity countless questions have been asked for which laser light has provided the answer. Numerous questions have also...Powered by WPeMatico

Smart buildings through innovative membrane roofs and façades

Abuja, african inspired, BLOGS, BUSINESS, IkaTv, Innovation, Innovation Africa, wazobia companies, Youths
The Cooperative Research Project FLEX-G started on June 1, 2017 under the federal construction technology initiative named ENERGIEWENDEBAUEN funded by the German Federal Ministry for Economic Affairs and Energy (FR 03ET1470A). The main goal of the research project is to investigate technologies for the manufacturing of translucent and transparent membrane roof and façade elements with integrated optoelectronic components. The focus lies on a switchable total energy transmittance (often referred to as the solar factor or solar heat gain and “g-value” in Europe) and on flexible solar cell integration to significantly contribute to both energy saving and power generation in buildings.Solar modules and a variety of energy management systems are well established in small and large buildings to
