Hey its a open air microwave oven
Here’s an idea: why not put technology into plates that lets them keep our food warm for us? That way, things won’t get cold on our plates and we can keep the microwave turned off. And heck, maybe we could run enough juice through them to cook a whole meal while we’re at it.
The designs for conductive plates are just concepts at the moment, but the technology is all available now to make these a reality. The downside would be, of course, that you’d need to have cords at the dinner table, not to mention the logistics of washing plates with plugs in them. But hey, it’s certainly a neat idea, isn’t it?
