two 12v 300w water heater elements
So your using this big contraption with 600W right.....
As osmium said, dont think so.... nicodem is right you need a shitload more power, so high that using a gas burner would bee more efficient.
Are you going to insulate the rest of the container?
And my question still remains, i know you are distilling e/o but what the hell are you distilling from it at 100oC??? ie what e/o starter and what fraction you want to remove from it? at atmospheric pressure 100oC wont get you much.
