So, I've decided which invention that I want to create first... (Mostly because I can afford it sooner thant he others.) And I was wondering what you thought about it. I can't say how it works, but I can tell you what it does.
My first invention will allow a person to venture into extremely cold areas (including immersion into water) without any chance of hypothermia, frost bite, or other ailments from the cold. And they would be able to do so without being hampered by equipment and all that. Using my invention, you wouldn't be able to tell the difference between two people wearing parkas, if only one were using it.
