Same Function For Much Less Money

Here is a good illlustration of ARIZ approach with providing function by an X-lement, then System itself, and finally Operating Zone itself.

Instead of heating or cooling the entire house the duvet is doing this directly for the body during sleeping, reduce the energy consumtion and save money. What is the next, a duvet with alarm clock function?
