As you may know, incandescent bulbs are filled with vacuum, and I understand that new EPA regulations have curtailed the mining of vacuum in the Washington D.C. area, where the largest U.S. deposits of vacuum are located.
The good news is that many other countries have this resource and can produce quantities sufficient to fill all the light bulbs they can produce without government intervention. So, we need not fear for at least the rest of our lifetimes. Where future generations may find this precious commodity is anybody's guess. . .
Yeah well, Frank knows a bit but as for a shortage of vacuum he has missed a major resource in the USA - Rap music. It sucks more than any vacuum pump I've ever owned (with apologies to any rappers who happen to repair guitars).
We ought not to exploit the resources of those underdeveloped countries. When vacuum is removed, it's gone forever. Just say no to incandescents, like we have here in the USA!
You can still buy incandescents, made in China of course, but you will just have to become accustomed to changing them after twenty minutes of use. This is the new standard for "mean time before failure", went from 1000 hours to 0.3 hours......
If needed for the sake of vintage bulb lovers, I can sell parts of my personnal 33 years old vacuum stock. It's kept in my head for now.
