You'll laugh, as I did, the first time you hear about JVC's sake-soaked wood cone speakers. Soaking speakers in sake? Sufferin' succotash! Say it isn't so, Sam.
As you might guess (or maybe not if you haven't spent much time thinking about it), it's pretty darn difficult to bend a solid sheet of wood into a cone shape without having it snap, crackle, and pop on you. Evidently, someone at JVC took this as a real challenge and spent 20 years trying to figure out how to do it. Somehow (I'm sure it was as the engineers were just about to give up and were drowning their sorrows in a bottle of sake) someone in the lab spilled his sake on the wood sheet and - eureka! - the sake solution was discovered.
I pour liquor on my stuff all the time and it doesn't net me millions of dollars in new technology copyrights/what-are-patents.php">patents. Hmph!
