IV.31 - Vegetable Diodes?

The same group at Digital that brought us the world's fastest microprocessor has also developed the world's only known light-emitting horseradish rectifier. (Horseradish rectifers in general are uncommon, let alone light-emitting ones.) Read on:

Dr. Chudobiak,

I would like to direct your attention to a description of an experiment I conducted with colleagues at Digital Semiconductor a few years ago. We constructed a light emitting "diode" of sorts from a sample of horseradish kim-chi. It rectified. It emitted light. It emitted a stench that could raise the dead.
