As humans it's in our nature to investigate, innovate and solve problems. This curiosity means we make things, create things and develop new technologies. You can look back thousands of years for basic examples of technology pushing civilization forward. Most people don't understand the rapid change technology has on their lives... or the speed at which a sea change occurs. For example, the following are the five 'Great Ages' of human progress and their approximate duration: Stone Age - 3.4 million years Bronze Age - 2,500 years Iron Age - 500 years Industrial Revolution - 80 years Information Revolution - 20 years You'll notice the length of each 'age' diminishes as technology improves. The computer industry calls this trend 'Moore's Law'. It dictates that computer processing power doubles every 18 months. Graphene is 200 times stronger than steel... 150,000 times thinner than a human hair... More flexible than a sheet of paper You may have heard about Graphene. If you haven't, it's a newly discovered, very special refined form of graphite. It's a one-atom-thick sheet of densely packed carbon atoms arranged in a honeycomb lattice. Take a look: ATT1.jpeg Put simply, it's a sheet of carbon atoms 150,000 times thinner than a human hair. Under a powerful microscope, it looks like chicken wire. But what's so special about it? Everything For starters, it's 200 times stronger than structural steel; it's so strong you could suspend an elephant from a single strand of Graphene, and the strand would not break. It's extremely lightweight. Soon, everything from bicycles and boats to airplanes and cars could be made out of graphene composites. And when they are, their energy efficiency and durability could skyrocket. But, that's just the beginning of what this new 'smart material' can do. Not only is it the strongest material researchers have ever tested, it's also one of the best conductors man has ever found. IBM has already created a graphene-based processor capable of executing 100 billion cycles per second. Researchers believe that in the future, a graphene credit card could store as much information as today's computers. This one material alone could prove more revolutionary than - and soon REPLACE - plastic, Kevlar and the silicon chip In fact, it's such a breakthrough that the first two scientists to successfully produce single-atom-thick crystals of graphene were awarded the 2010 Nobel Prize in Physics. In just two years, over 200 companies from a wide array of industries have researched the magical potential of graphene: Scientists in the US and China are already using tiny graphene-based probes to target and identify tumors in live mice. They hope similar graphene-based particles could shuttle cancer drugs to tumors, or even kill tumor cells directly. Engineers at Northwest University, Seattle, found that specially crafted graphene electrodes could allow a lithium-ion battery, like those found in your smartphone or Toyota Prius, to charge 10 times faster and hold 10 times more power. And in 2011, chemists at Rice University, Houston, created graphene-based thin films, unlocking the secret to incredibly flexible, super-durable touch screens and solar cells that can wrap around just about anything. ATT2.jpeg Kiss goodbye to shattered screens Samsung has already said its flexible displays should enter full-scale production later this year, and it expects to have a dozen more graphene based products on the market within the next five. IBM, Nokia and Apple are hot on their heels too. Touch screens, processor chips, casings, and batteries (in everything from PCs and HD TVs to tablets), mobile phones and hybrids could all be made with graphene. It could change entire industries, economies, and our lives. Imagine HD TVs as thin as wallpaper, Smart phones so skinny and flexible you can roll them up and put them behind your ear, and so durable you can beat them with a hammer! Imagine if you could eliminate breast cancer or prostate tumors with a simple injection or by swallowing a graphene-charged pill. Imagine if your house were strong enough to withstand a bush fire, and your windows processed enough solar energy to heat your home in winter and cool it in the summer. Or if your car were 6 times lighter and 20 times stronger. The effects would be staggering! Fuel-efficiency
RE: [Texascavers] TCR!
I second that, but even better was seeing many good friends. It's been about 4 years since I was last able to make it to TCR. I hope it won't be that long before my next one. My thanks to all who make it possible.
