Energy workshop for Kids!

The energy workshop for kids was held at St Elmo Village in Los Angeles.  We learned how to make passive heating (rocket stove) and cooling (zeer pot)systems.  We learned about how combustion happens and why insulation is important to retain heat. My demonstration rocket stove had flaws because I am not the best at cutting metal so view the video with one in action!

Low Tech Refrigeration Solutions – The Coolgardie Safe & Zeer Pot
We learned about the zeer pot and how various fruits and vegetables can be preserved without electricity.  We learned that refrigeration means actually removing the heat from an object to cool it. Here is a link to another passive cooling system called a Coolgardie Safe.  This was used in Australia in the harshest of climates.
