The other day I've been thinking of the "light bulb conspiracy". Y'know, the one where it's claimed that they've invented light bulbs that never go out (or at least have very long lifespans), but the companies never make them because they'd make a lot less money since nobody would need replacements.
But here's why I think that this cannot be the case. Even if they do think it would be bad business,
somebody else wouldn't. A big light bulb company would already have steady business, but an upstart wouldn't. They'd have trouble competing with the big boys. Manufacturing bulbs that don't go out would be a surefire way to level the playing field and rocket them to success, making the inventors very wealthy people indeed.
Now, if the mythical immortal bulbs were originally invented by a big corporation, of course they'd guard the secret for exactly that reason. But they could not keep somebody else from independently discovering it. The only way to prevent somebody else from making them would be to file a patent, which would put the secret out in the open (so we would already know about it and probably even how to make them ourselves) and would expire in 20 or so years, when everybody would be free to make these bulbs.
And the potential for independent discovery is big. The light bulb itself is commonly credited to Thomas Edison, but it would probably still have been invented without him. Perhaps it'd have been later, but he was not the only person working on the light bulb. It's more accurate to say that he perfected the light bulb than that he invented it. Likewise, Alexander Graham Bell wasn't the only guy who was working on the telephone, and so on. If there's a scientific principle that allows light bulbs to last forever, somebody's gonna find it sometime. And if that somebody is a big corporation who doesn't want the secret to get out, somebody else is going to find it anyway. The companies can destroy their special bulbs and their plans for them, but they can't destroy the underlying physics.
By the way, there is a
light bulb at a fire station in Livermore, California, that has never been turned off since it was first used in 1901 (although of course it's seen the occasional power outage). What about that one, then? Well, it's quite simple: the bulb is powered by only 4 watts. So it'll be lit for a very long time, but it won't be very bright. You can do the same thing with any bulb, really.
