Having just finished my first e-BIAB keggle, my mind has immediately started to wander: why couldn't the heating element be attached outside the kettle, on the bottom, like an electric skillet? I'm sure there are issues to be overcome (sourcing the right bendable element, figuring out how to attach it semi-permanently, maximizing heat transfer up into the kettle as opposed to down and away), but not having the element inside the kettle would certainly have some advantages. I'm imagining an element fixed to the outside bottom dome of a bottom-drain keggle.
I've done a bit of searching in the Electric Brewing and DIY forums and haven't found anything about this, so I thought I'd pose the question.
