Some examples of appropriate technology are well-known to us; things like life straw, Q drum is one of them.]]> 2021-10-12 05:32:44 UTC https://padlet.com/LEEDONGHU/u0xlos5xgqrvu2o81645023690/wish/1809746773 https://padlet.com/LEEDONGHU/u0xlos5xgqrvu2o81645023690/wish/1809748319 1. Fill the gap between the large and small jars with wet sand.
2. Put food in a small jar and cover it with a wet cloth.
(The refrigerator is made using the principle of vaporization heat, which takes away heat as moisture vaporizes.)

It is usually used to store harvested vegetables or fruits, and the timing of use is determined in consideration of weather and demand.
Currently, it is distributed and used in 11 states in Nigeria.]]> 2021-10-12 05:33:41 UTC https://padlet.com/LEEDONGHU/u0xlos5xgqrvu2o81645023690/wish/1809748319 https://padlet.com/LEEDONGHU/u0xlos5xgqrvu2o81645023690/wish/1809757970 WHO? Mohammed Bah Abba
WHEN? 1995
WHY? Because it was difficult to supply electricity in Africa, there was no refrigerators there
ADVANTAGES: Cheap price($1), easy to use, Eco-friendly, Can keep food for 20 days in a cool condition]]> 2021-10-12 05:39:32 UTC https://padlet.com/LEEDONGHU/u0xlos5xgqrvu2o81645023690/wish/1809757970 https://padlet.com/LEEDONGHU/u0xlos5xgqrvu2o81645023690/wish/1815683718 WHO? Professors at Massachusetts Institute of Technology (=non-profit organization)
WHEN? 2005
WHY?  It was almost impossible for the African children to use internet. Some of them didn't even know the existence of internet.
ADVANTAGES: Cheap price ($100)
PRINCIPLE: OLPC is trying to enjoy the benefits of education by delivering a strong and economical XO laptop to children in the third world as a valid means to solve that problem.
It is only a small textbook and has a built-in wireless Internet card, so you can use the Internet outdoors.]]> 2021-10-14 02:08:14 UTC https://padlet.com/LEEDONGHU/u0xlos5xgqrvu2o81645023690/wish/1815683718 https://padlet.com/LEEDONGHU/u0xlos5xgqrvu2o81645023690/wish/1817644645 [1] Prevention of diseases
Diseases can be prevented because vegetables can be kept fresh for more than 20 days.
[2] Profit increase
Fresh vegetables sold at high prices and farm income increases.
[3] Employment effect
Jobs are provided to people as the profits generated by selling crops enable them to hire people on farms.
[4] Education
Children can go to school because their livelihood stabilizes as their profit increases.
[5] Vaccine/Medicine storage
In areas without refrigerators, pot-in-pot coolers can be used to store vaccines or medicines.]]> 2021-10-14 16:34:51 UTC https://padlet.com/LEEDONGHU/u0xlos5xgqrvu2o81645023690/wish/1817644645 https://padlet.com/LEEDONGHU/u0xlos5xgqrvu2o81645023690/wish/1817705010 The combination of scientific theory and wisdom of life to create pot-in-pot coolers and the improvement of African people's quality of life seem to be representative examples of appropriate technology. On the surface, it was similar to Korean crocks, but it was impressive that it used sand and water. It's not grandiose, but I think it's great that it improved the living environment of African people.]]> 2021-10-14 16:59:08 UTC https://padlet.com/LEEDONGHU/u0xlos5xgqrvu2o81645023690/wish/1817705010 https://padlet.com/LEEDONGHU/u0xlos5xgqrvu2o81645023690/wish/1818673188 It is certain that OLPC(One laptop per children) is a great invention, since it made people in economically poor countries use internet in a low price. Even though it is a invention that has made more people use internet, I do not think that OLPC has the same significance as other inventions made by using appropriate technology. This is because although OLPC is much more cheaper than other laptops, it is almost impossible for the poor to pay $100 for a laptop. Therefore in conclusion, I do not deny with the fact that OLPC is a good invention, but it should lower the price if they really want to give one laptop per a child.]]> 2021-10-15 02:37:44 UTC https://padlet.com/LEEDONGHU/u0xlos5xgqrvu2o81645023690/wish/1818673188 https://padlet.com/LEEDONGHU/u0xlos5xgqrvu2o81645023690/wish/1826195439 I felt sorry that African people didn't know that the Internet existed in the world, and I'm so grateful that they made such a good thing. ]]> 2021-10-19 05:26:28 UTC https://padlet.com/LEEDONGHU/u0xlos5xgqrvu2o81645023690/wish/1826195439 https://padlet.com/LEEDONGHU/u0xlos5xgqrvu2o81645023690/wish/1847726311 Pot in pot is a great invention to save foods for a underdevelopment citity who does not have a refrigerator like us.
