I knew that, I was trying to say "So What" in a more polite way. My point was this is better then what was available before. It is a real improvement in the peoples lives who use it: more fresh food consumed, food costs go down and probably less food poisoning by trying to stretch one more day from what we have bought for dinner. It is cheap enough to be purchased and simple enough to be maintained by untrained people. This is a solid step in the better direction.
