"Eternal Flame" for Hestia

Does anyone keep an "eternal flame" for Hestia? I like the idea of keeping a flame on my altar all the time for Hestia. I don't know if it has any historical basis (other than the smoldering hearth fire the ancients had), but I think it'd be a good modern innovation. I use a giant novena candle during the day, and was thinking of symbolically transferring the flame to an electric candle when I go to sleep. Thoughts?

That is no modern innovation — temples in Antiquity would have continually-lit fires, and similar, smaller scale sanctuary lamps have remained a feature of Catholic and Orthodox Christian churches, Jewish synagogues, and Orphic telesteria all the way down through the centuries.

If you are interested in keeping an eternal flame lit, here is an article with some recommendations and instructions from the Orphic sodality:

Thanks for the link. I did a Google search before I posted but couldn't find anything.
