Nov, 11, 1930 is the date Einstein who is one of the greatist phisicist receive an American patent for a new kind of refrigerator. This mechanism is differnt from modern refrigerator. It doesn't need freon or electricity, so it uses ammonia, butane, and water instead. This idea is great for no freon and no electricity. However, Einstein's design isn't very efficient at cooling per unit of energy input. Now, other team is improving this system. I respect Einstein, I think this system is very nice, but if ammonia is used to refrigerator, I don't want to use it. I worry about heavy accident as the gas is leaked. Because ammonia is very dengerous chemical compound as everyone knows. Ammonia gas is very bad smell!!. Do you think so?

Hi TAKA...I like your article and its very intersting. I think that the Amonia gas is a dangerous gas, and you are right it smells very bad. I think that one day we may use this gas, because maybe we will not find any other way.
ReplyDeleteHi Taka, Amonia Gas is so dangerous and very bad smell. One of these risks of this gas poisonous has effects on the eye and respiratory.
ReplyDeleteYes this gas is very dangerous and has a bad smell. I don´t think that we need to use this things again
