What invention would you like to see?
From time to time I think of a gadget that ought to exist but does not seem to. The two that are on my mind right now are: 1. A kinetically charged collar blinker. There are flashlights that you shake to charge, there are little flashing lights you clip to your dog's collar-- I want to cross them. 2. A plate warmer that you put on the table or TV tray and plug it in to keep your plate warm throughout the meal so you don;t have to eat cold food or microwave it halfway through dinner. It could be USB for those that eat in front of their computers.
