There is no such thing as science "Fiction". It's science "Not Fact--YET". Man has a great capacity to dream something and then find a way make it real. The more tools we make the more we are allowed to make real. It's unbelievable what we have today. Just think of all the stuff we have that we don't even know about. I think it was Carl Sagan that said, "The Universe invented Man to understand itself". These things are just so cool and the more we get into composits, the stronger the parts will become. Did you see that engine block model on the table. Just think how cool it would be to order an 800 cube engine, all out of composit, and have in in 1 hour. And light enough to pick up and put in your trunk. By hand. Mark L
