The phase-change incubator is a low-cost, low-maintenance incubator to help test for microorganisms in water supplies. It uses small balls containing a chemical compound that, when heated and then kept insulated, will stay at 37°C (approx. 99°F) for 24 hours. This allows cultures to be tested without the need for a laboratory or an expensive portable incubator. Thus it is particularly useful for poor or remote communities. The phase-change incubator was developed in the late 1990s by Amy Smith, when she was a graduate student at MIT. Smith has also started a non-profit organization called ''A Drop in the Bucket'' to distribute the incubators and train people to use them for testing water quality. Embrace, an organization that came out of Stanford University, is applying a similar concept to design low-cost incubators for premature and low birth weight babies in developing countries. == See also == *Appropriate technology 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Phase-change incubator」の詳細全文を読む スポンサード リンク
