I definitely agree with GH and CVT. As much as induction tops are aesthetically more in line with high end residences, most of our design clients still request for a so-called dirty kitchen, equipped with LPG stoves, where the actual cooking is done. In short, the "clean" kitchen is most often for show only.

Unless you can be assured of 24/7 electricity, or have a stand-by generator or alternate power supply, LPG is, in reality, more practical. In my own household, we use LPG stoves in the dirty kitchen. We also have a charcoal-fed stand-alone unit, one that I got years back at one of the motor shows. It is actually very usable and cheap to operate, especially if you use those recycled organic charcoal briquets. : )
