Many people are now using this tactic in Africa. This benefits us by making food healthier, tastier and safer to the environment.]]> 2017-09-20 14:17:07 UTC https://padlet.com/john_rathgeber/kv5c9hp2z2v1/wish/189339919 What I've learned furthermore about cooking things with solar energy. john_rathgeber https://padlet.com/john_rathgeber/kv5c9hp2z2v1/wish/189746458 I've learned that there are 3 different types or things that are good for cooking things with solar energy: reflector, absorber, and transmitter or something see through.]]> 2017-09-21 13:50:54 UTC https://padlet.com/john_rathgeber/kv5c9hp2z2v1/wish/189746458 What I've learned even more about reflecting, absorbing, and transmitting heat. john_rathgeber https://padlet.com/john_rathgeber/kv5c9hp2z2v1/wish/191247312 I've learned that If you set up a tin foil sheet to reflect heat to a transmitter, which will magnify the heat into the absorber, it will trap the heat into the the box of foam, which is the absorber, and will heat up the item inside.]]> 2017-09-26 13:51:10 UTC https://padlet.com/john_rathgeber/kv5c9hp2z2v1/wish/191247312 Last Entry about solar radiation. john_rathgeber https://padlet.com/john_rathgeber/kv5c9hp2z2v1/wish/191682551 I know that there are three types of materials for thermal radiation to work, absorber, transmitter, and reflector. Some materials that are good at those are tin foil as reflector, foam as absorber, and cling wrap as transmitter. Solar cookers and oven use those things to cook food. Solar cookers are open, reflecting heat from the sun to cook food. A solar oven captures the heat inside a box, and cooks food inside the box.
