< IMG SRC = "/Uploads/Blogs/C2/B9/IB-FRUL8T77L_7C6FC931.jpg" Alt = "three students invented a refrigerator that works without electricity"/> ~ < P > In India, three teenagers have created a salt refrigerator to help it vaccines and medicines to rural areas. Drugu Chaudchari, Mitran Ladhahanius and Mridul Jain from Indor won this year's Earth Prize of $ 12,500.
< p >According to Business Insider, the refrigerator does not require electricity. Instead, he uses salts that extract heat from the environment when dissolved in water.
< P > Hearing how difficult it is to send the vaccine from Covid-19 to & nbsp; rural terrain without electricity, these & nbsp; guys decided to find a salty cooling method.
~ < p > their invention is called Thermavault. They plan to build 200 & nbsp; such refrigerators and & nbsp; send them & nbsp; to & nbsp; 120 & nbsp; nbsp; hospitals for testing on & nbsp; earned 12 500 & nbsp; dollars. < 62 < P > Thermavault is intended for transportation of vaccines, other medicines and & nbsp; materials, and & nbsp; even for transplanting organs.
< p >& laquo; we & nbsp; have been able to store vaccines inside thermavault for almost 10-12 hours & raquo;, & nbsp; & mdash; Dr. Pritish told in & Rsquo; Ias, an orthopedic surgeon who tested the device in & nbsp; hospitals V & nbsp; one in & nbsp; indore. & laquo; this & nbsp; it will certainly be useful in & nbsp; remote places, villages & raquo;.
~ < p > Some salts have a cooling effect when dissolved in & nbsp; water because & nbsp; nbsp; charged atoms or ions, with & nbsp; which they make up. This & nbsp; separation requires energy that ions are extracted from & nbsp; the environment, cooling water around it.
~ < ~ p > 62 ~ Chaunchari, Ladhahani, and & nbsp; jine; jine was found in & nbsp; nbsp; nbsp; nbsp; 150 & nbsp; salts that could b & nbsp im & nbsp; most effective.
< p > then they borrowed the laboratory in & nbsp; Indian technology institute to test these & nbsp; 20 & nbsp; salts. On & nbsp; their disappointment, none of & nbsp; these salts are not & nbsp; cooled water enough.
~ < p >& laquo; although we & nbsp; nbsp; we have found the best salt, we & nbsp; nbsp; nbsp; nbsp; nbsp; nbsp; natural sciences for & nbsp; nine & rsquo; class & raquo;, & nbsp; & mdash; Teashars tells.
< p > ~ Finally, the Trinity with & Rsquo; nbsp; nbsp; nbsp; ammonium chloride supports the temperature from 2 & nbsp; nbsp; nbsp; 6 & nbs; vaccine.
< P > Adding to & nbsp; octidrate mixtures of barium hydroxide allowed to reach the temperature below zero by & nbsp; celis. This & nbsp; ideal for some vaccines and & nbsp; transplant organs.
< p > approximately three months the boys created a prototype and & nbsp; nbsp; began to test it in & nbsp; local hospitals.
< p > thermavault & nbsp; & mdash; This is & nbsp; isolated plastic container with & nbsp; copper inner wall, in & nbsp; which place vaccines or organs. Cooling solution made by dissolving salts in & nbsp; water, poured into & nbsp; space between plastic outer wall and & nbsp; copper inner wall.
~ ~ < p > Usually for the delivery of vaccines in & nbsp; rural terrain use cold containers, in & nbsp; which use conventional packages with & nbsp; ice.
~ ~ ~ > 62 > 62 ~ < P > Ammonium chloride solution used in & nbsp; thermavault, can be used repeatedly in & nbsp; field without electricity. The Trinity stated that & nbsp; im as & nbsp; not & nbsp; nbsp; you need a freezer to get & nbsp; ice.
