Energy and domestic appliances

I have a now gas stove in my house and yes, it is very pleasant. Yet -- a couple of things have stayed with me through the process of buying it. Many stoves that look nice actually only have huge gas rings to deliver the heat. This means that unless you have a huge, flat-bottomed pan much of the heat will go around your pan and cause the food to get burned on to the side wall of said pan. So not only are you wasting heat, but you're causing a dishwashing nightmare for later. This is easily cured. For folks like me who need to heat up a small quantity of something all you need is a smaller ring. Yet -- try finding a stove that has those and looks halfway decent. An idea that is even better is that each ring can be made of two more more concentric flame rings. Big pot? Light them both. Small pot? Just light the smaller one. In Europe, where power is expensive, they've had this system for a long time. Why not here? In fact, think about that for a second: in Europe there are cars that routinely deliver 60 mpg, and have done for decades. If I were paying $10 a gallon I'd want that too. But here energy is still cheap - laughably so. Energy efficiency is being quietly subverted by simply not offering products that are truly energy efficient. Big business wins again.
