The solution would be to install a very small remote controlled welder
inside each incandescent light bulb. Then when the bulb burns out, the
owner could use his remote, turn on the welder, and weld the filament
back together, without ever having to open the glass enclosure. The
remote would need a joystick control, so the operator could position the
welding rods precisely at the filament break.

Robotic welding with a very small incision in the glass. You could blow
a fan over the opening, like they do at supermarket doors, so the vacuum
wouldn't leak out.

Or refill after welding with ArNe, which is a better gas than vacuum gas
anyhow.

Geeezzzzz, I thought you just needed to hold a vacuum cleaner hose by
the incision on the glass to get the vaccuum back in the bulb....

Wouldn't that suck the vacuum out? Then it would have no vacuum.
