Mermaid is a mythological aquatic creature that could breathe under water as well as on land and looks as if a half  human .Science makes man to become a mermaid or mermen which could breathe on  land as well as water.Alan Izhar-Bodner, an Israeli inventor, invented a special apparatus by which the divers are able to breathe under water without those massive oxygen tanks.The apparatus makes use of the dissolved oxygen in water to breathe ,as if a fish do.

Behind the working

The working principle of the apparatus is ‘Henry’s Law’.It states that the gas dissolved in a liquid is directly proportional to the pressure applied ie  more the pressure applied larger the  amount of gas that can be dissolved.This phenomenon could be observed while opening a soda can.When we open the can the gas evolves, it happens due to the decrease in pressure there by some amount of dissolved carbondioxide in it escapes to the atmosphere.

The Border’s apparatus consist of an inlet to take water from the sea which contains dissolved oxygen.It is stored in a chamber where a centrifuge is used to reduce the pressure which separates the dissolved oxygen from water.Then using a separator the oxygen and water is made to store in two different chambers from where the water is expelled back to sea.Like other under water breathing apparatus the oxygen is fed to the divers breathing mask and the exhaled air is removed through an outlet to the sea.

The effort of humans to breath like a fish started very long ago,many scientist made attempts to make a means through which humans could breathe under water but non was fruitful.But now , it made a ray  of scope and the problem that stumbles is the power needed for the centrifuge to work, if we are able to produce this power using solar energy then a lot of mermens and mermaids would be born.
