One example of energy transfer is the use of solar refrigeration systems. Here is a typical solar refrigerator found in Utinta about 1450 kilometers from Dar es salaam in Tanzania, it was installed since 2002.

  1. David hi, you have to explain what TYPE of heat transfer you can see in the photograph (convection, conduction or radiation). Also please note that the thing(s) you photograph should be outside the scope of pharmaceutical cold chain. It must be from daily life. Do not forget o add a TITLE to your postings. Cheers UMIT
