Originally I was aiming for an idea to minimize the extra heating in the apartment. But I noticed a much more important feature of the heat blanket.
To me a heat blanket squeezed behind my back has a soothing affect. Feeling comfortable lets me concentrate much easier. Thats why I think people who have a hard time to concentrate might be helped by such a simple device.
So the idea is simple. Make yourself a StudyChair. Just squeeze an electric heat blanket behind your back and the backrest.
The image is my manual solution to a 1000 points traveling salesman problem. The conclusion I made is that. Its ridiculus to try to concentrate yourself trough such a hard problem. You really have to divide the big problem into smaller parts. Find similar strategies to this and you solve anything.
