Ever wonder why microwave designs have remained constant through the years? I have. Big. Rectangular. Bulky. I suppose it had something to do with the mechanics of how a microwave works. Perhaps technology can overcome these mechanics and help turn the But-On Koncept into a reality. Here is a circular microwave that loads from the top. Besides the normal microwave functions, it also features a removable inner lining that makes cleaning easy. Oh yeah, instead of white, black, or cream, you can have yellow, orange, or blue.
