At the expense of being ridiculous: You buy a car its's all plastic, where'd the steel go? Buy a house, OSB board and composite products, where'd the wood go? Buy a chicken pattie, made with beak and legs and neck, where did the chicken meat go? Go to by produce, everything is seconds, where's the good stuff? Everything has been reduced to some chemical formula to "taste like, act like, perform like" what the heck happened to the real thing? Did the real stuff disappear into a black hole? -------------------- I suppose what got me thinking is USG is trying to develope sheet rock that would absorb heat during the day and release the heat during the night. Energy efficient. Crack me up if they ended up engineering a piece of wood.
