We were just fascinated with the Blu Ray discs that store data up to 50GB and now make way for specially coated DVDs which could store data up to 50TB. Yes, you read it right, its 50 terabytes. Do we need that much space? Hell no, but its a technology developed by a professor of the Harvard Medical School in Boston, V Renugopalakrishnan.
The coated layer on the DVD is a protein made from tiny genetically altered microbe proteins, known as bacteriorhodopsin (bR). The bR is used to capture and store sunlight which is then converted to chemical energy. It is then converted to intermediate molecules which lasts only for hours.
Renugopalakrishnan have managed to modify the DNA which produces bR that are used to produce intermediate molecules and can last several years. The plus point of this protein is that it can be packed to DVDs, CDs or any other film. Just hope that they won’t be highly priced.
