As the BOFH battles the architects Comments We begin the weekly comments mishmash with a close look at fish sperm. Apparently there are many, many salmon farmers sitting around wondering what to do with all those gallons of salmon spunk they don't need. So to forestall them getting any bright ideas, a top light-emitting-diode boffin has announced plans to use it for a more efficient LED. The DNA in the salmon semen apparently traps electrons for longer than standard materials, leading to a brighter, longer-lasting LED. Naturally though, you identified the important issue: the spunk.â¦
