Sustainable Tech Hack Night
Details
Let's get to work!
A few of us are already hard at work on a thermosiphon solar air heater based on this design (http://www.builditsolar.com/Projects/SpaceHeating/mssungrabber.htm). The heater works but we're not yet sure how well so we're building some instruments to measure it.
Feel free to join in or bring ideas of your own!
