Many research groups across the world are in the process of developing so-called ‘Energy Harvesting’ (EH) techniques to extract electrical energy from human actions. (see for example, Implementing a knee-energy harvester). The Choo Lab at Caltech specializes in such things, and researchers there have recently developed a system which is designed to power portable electronic […]

Hummingbirds get hot too
No machine can be 100% efficient – and Hummingbirds (Selasphorus calliope) are no exception. As a result, when they flap their wings (typically at around 50Hz) they generate considerable quantities of heat. To find out how much, investigators at the Department of Biology, George Fox University, OR, and the Division of Biological Sciences, University of […]
