Hot plates are undoubtedly very useful. Not only can they be used as a scientific heating device, but they make stove top cooking more portable and convenient than a microwave. I imagine that, had I a hot plate, I could enjoy freshly warmed chili during class by strategically sitting near an outlet. I could warm my hands rapidly on a chilly day, and I could have a space heater for my room. Just think of all the possibilities. I bet you want one too.
Today I ate a combination of foodstuffs that managed to satiate me before it disappeared. It consisted of a baked potato, rice, and chili. And some tortilla chips.
