It's a great idea, if you do it right, and scale it up, which is what industry had been doing for decades. The problem with the MIT version is it was a toy, that also didn't work, and was developed by people who had no grasp of the problem space. If you look at a Hasbro Easy-Bake Oven, it would be easy to discount "ovens" as a good way of cooking food. They're too small, and the incandescent bulbs don't produce enough heat. How could anyone thing this was a good idea? It is...unfortunate...that the MIT name was attached to a group of people trying to pass off shoddy malfunctioning knockoffs of toys as new innovation.
