Jackie Chan Blu-ray disc boosts solar panel efficiency by a massive 22%

Researchers at Northwestern University have used Blu-ray discs — of Jackie Chan’s seminal Police Story 3: Supercop, to be exact — to increase the efficiency of solar panels by a massive 22%.

This one’s a bit crazy, but stick with me. Blu-ray discs, like CDs and DVDs before them, consist of a thin layer — or layers — of recording medium sandwiched between two bits of plastic. Data is stored on this medium in a series of pits — small indentations — that are about 75nm long. To read the data, a laser is bounced off the recording medium — where the medium is smooth and untouched (usually referred to as islands), the laser light bounces straight back into a sensor; where the pits are, the laser is reflected differently. Thus, binary data can be stored and read.

they need to find more efficient ways of making solar panels. than the current ways.

ya sure they have long way to go
