Actually, there are extant "recipes" on Ancient Egyptian Papyri for creating one of these. They aren't electric, but actually Alchemical (Al-Khem means "Of Egypt"). These Perpetual Lamps utilized a closed system that fully recycled what was consumed, just causing the liquid to change to gas state and back to liquid state. They would seal the Lamp between two glass halves or shells. I've thought of making one myself just to see if the formula actually works, but as it requires the use of an Asbestos Wick, I've considered otherwise.
When I get home I can dig out the Papryi references and post the translation of the formula for these Perpetual Lamps of Ancient Egypt.

According to some skeptics the image of the Egyptians holding that lightbulb is them holding an "eggplant"...
