What does the new Disney movie Frozen have to do with engineering? How might the plotline of Frozen changed if any of the characters were engineers? Now, I’m not saying that engineers don’t believe in the power of sisterly love to fight climate change, but I am saying that we would not have taken the time to let our sisters freeze in hopes that we could figure something out (you’re welcome, Natalie, my awesome twin sister). You don’t believe me? I’ll prove it to you.
Below are three neat devices that student engineers have invented or are developing so that they can take temperature into their own hands.
When a baby is born and he or she is deprived of oxygen, which impedes brain function, possibly leading to cerebral palsy, mental disability, or death, what do you do?
Cool the baby.
That’s right, there is a 72 hour window in which you can lower the baby’s temperature to effectively rescue brain cells. A team of biomedical engineers at Johns Hopkins invented a $40, easy-to-use solution that is built of a clay pot, plastic-lined basket, and a sand and urea-based mixture. When water is added to the mixture (what is used in cold-packs), the heat is extracted from the basket holding the child. Brilliant!
Babies are important. Not only are they adorable, but they are the future. A group of Stanford students who understood this saw that many of the 4 million premature babies that die within the first month after birth per year are from developing countries. The main problem for these infants is regulating their temperature. These Stanford students invented a sleeping bag-like solution that can maintain a constant for up to six hours without electricity. The infant warmer is composed of a phase-change material that absorbs heat and slowly disseminates it to the infant.
Control that body temperature; don’t let it control you. And save some lives along the way.
We usually think of developing countries as warm, tropical places. This presumption is not necessarily always true, though. A portion of developing countries lie above the Tropic of Cancer and temperatures can dip low, causing a need for heating systems to avoid freezing. Students at Lulea University of Technology in Scandinavia created an “simple stove with integrated heat recovery” at a minimal cost that could be used in North Korea, Afghanistan, Mongolia, Siberia and northern China.
What other projects do you know of? Where are some areas that need improvement from engineers regarding temperature? Are there any other ways that engineers relate to Frozen?
