Turn up the Thermostat and Get a Fan for Most Comfort and Power Saving

Written by , on February 10, 2017

A university study has shown that thermal comfort, perceived air quality and symptoms of sick building syndrome are reported to be equal or better at 26°C and at 29°C, rather than at the common “set point” of 23°C, if a personally controlled fan is used.  Read more »

Wind Turbine Mimics a Hummingbird

Written by , on January 6, 2017

A Tunisian startup, Tyer Wind, has developed a “wind converter” which is equipped with flapping wings rather than blades. The action of the wings mimics the motion of hummingbird wings  Read more »
