22 Feb THE SCIENCE INSIDE - WiFi

In light of the challenges currently faced by the South African national power utility Eskom, we look at how scientists at the Massachusetts Institute of Technology (MIT) found alternative ways of harvesting electricity from WIFI signals. In unscience, we discuss how new research findings suggest that the brain is able to subconsciously learn new vocabulary from a new language during the upstate of sleep. Lastly we spoke to Dr Kahesh Dhuness from the Council for Scientific and Industrial Research about their underwater communication technology that is able to connect deep sea vessels to other networks wirelessly, using wet-end sonar transducers and arrays designed for specialised underwater applications.
