2-2 ① How It Got Started (20230 임준이)
Even if there was no refrigerator in poor parts of Africa, there was a problem with food storage because the supply of electric energy was not smooth.
2-2 ② How It Got Started (20222나연우)
Many clay pots from around 3000B.C. were discovered in the Indus Valley Civilization and are considered to have been used for cooling as well as storing water.

2-3 How it operates (20229 이현민)
A small pot put in a pot it can store food cold. There is sand between a small pot and a pot and next pour the water into the sand. It can usually store vegetables and fruits. The method is that moisture takes away the heat and lowers internal temperature.

The meaning of appropriate technology(20222 나연우) https://padlet.com/LEEDONGHU/7afm21rj4joykqbw1645023696/wish/1818630599 Appropriate technology is a technology that helps a life of human's quality improve in consideration of political, cultural, and environmental considerations.]]> 2021-10-15 02:18:56 UTC https://padlet.com/LEEDONGHU/7afm21rj4joykqbw1645023696/wish/1818630599 My opinion- Your criticism of the technology https://padlet.com/LEEDONGHU/7afm21rj4joykqbw1645023696/wish/1818645794 20229 이현민
Technology can create a comfortable life for humans. However, we will not grow because the convenience of technology eliminates the need for humans to try. And then robots will develop more than human. Our brain have limit but robots have big dater so robots will be smarter than us. Technology will develop further and we will not be able to catch up with the knowledge of robots. Therefore, we may be dominated by technology. 

20227 이서정_The reason why I think the technology is important.
Nowadays, We store some foods easily in the refrigerator. This is because the cold air in the refrigerator keeps the food fresh so that it doesn't go bad, but in the past, there was no refrigerator because the technology was not much advanced than now. In the past, when there was no refrigerator, it was difficult to store some foods for a long time. However, the pot refrigerator which is made by scientific principles, helped Africans to keep food cold instead of refrigerators. It can store food fresh for about a month. If we hadn't had a good idea of a pot refrigerator at that time, we might not be able to use a good refrigerator now.
