Looking at the recirculating BIAB (bag or basket), they're all based on a heating element in the wort. This isn't really an issue on it's own, but it does introduce limitations due to the volume of wort below the bottom of the basket or bag that's needed to accommodate the heating element. This seems to cause issues with high gravity beers. The Brew Boss is a good example where larger grain bills for a 5 gallon batch won't be completely immersed in the wort because of the space around the element.
It seems like a great solution would be to use an induction system so that you don't have that "dead space" around the element. The issue is that there's no system that allows feedback control of an induction burner.
How come nobody is building that? How difficult would it be for a DIY project?
