Bulb Replacement

Look at what would be needed to make bulbs:

1. Suitable glass tube stock for blowing (just as fragile to store as bulbs)
2. A gas source for heating the blown glass (I think we have already discounted storing gas)
3. Gas bottles, hoses, gas torches, valves etc. (and no practical way to make gas and re-pressurize gas bottles other than producer gas maybe from coal)
4. A suitable gas for the interior of the bulb, and once again all the storage or manufacturing, and chemistry for making such a gas.
5. A vacuum pump may substitute for shorter life bulbs, but this requires skill, a very specialized skill, to draw down on the bulb to create a vacuum.
6. The skills to blow, form glass, wind elements, insert elements, make gas, fill with gas etc.
7. Element making could only be really practical if element wire stock was also stored Imagine if we had to find and mine a suitable metal, refine it, then draw it out, and shape it. This alone totally rules out making lamps, unless all parts are pre-stocked.

Now why go to all this trouble to store and protect replacement parts that are equally as difficult to store as the bulbs they are meant to replace? All this to end up making vastly inferior lamps to what can be easily bought cheaply then stored. There will be millions of useless cars laying about, all containing about 10 of these lamps anyway? Coal gas heat and light and some simple reflectors for plants makes a lot more sense.
