Nanotechnology

in this video we'll explore nanotechnology the planet is shrinking meaning among other things robots will soon be traveling in your bloodstream so let's start the planet is getting smaller so let's mention nanotechnology we're talking about the nanometer the nanometer this is often a billionth of a meter we're talking about small here just offer you a thought of how small a nanometer is 100 thousand nanometers is that the size of a person's hair so take that hundred thousand and drive it all the way down we're talking small we're talking about the atomic level let me offer you an illustration here the American Society of Mechanical Engineers says that nanotechnology will leave virtually no aspect of life untouched and is predicted to be in widespread use by 2020 this was all predicted by Feynman with a world-famous physicist who said in 1959 there's many room at rock bottom what was he talking about well computers wont to fill a whole building now they fit on your wrists transistors are shrinking as we have seen earlier getting down by the mid-2020s to one atom in size what scientists have discovered is that the difference between one thing and another isn't its atomic makeup it's simply the order during which the atoms are put together this is often how they convert sand into silicon it's how we convert coal into gold how we take old sick people and switch them into young healthy ones okay that's off into the longer term near-term nanotech it is already here we have already got devices that by 2018 your smartphone will have a video projector in it which will produce 3D imagery yeah 2018 it's coming by 2025 it'll be the top of laundry nothing will get dirty by building textiles where dirt literally fluffs right off we're already saying robots in technology robots are now building other robots why can we need a robot building another robot because the robots that the robots are building are really really tiny right down to|all the way down to">right down to the molecular level this is often having huge benefits ultra high-yield agriculture zero pollution manufacturing cheap power environmental remediation even eventually personal space craft we're seeing medical nano robotics also we're watching artificial red blood cells artificial white blood cells once they find an infection they devour it already within the marketplace check out what is going on on in one sort of eye surgery immediately the the normal methodology painful injections big risk of infection and really expensive being replaced by nanoparticles that float in eyedrops you self treat reception you only give yourself an eye fixed drop quick painless same results because the surgery no risk of infection 90 percent cheaper that is the promise at hope of nanotech what you are looking at here every dot you see is an atom we're watching tiny robots which will be ready to perform glaucoma surgery gastric bypass surgery even provide dental repairs let me illustrate with you one among the foremost promising technologies on the marketplace it's called graphene to assist you understand what graphene is it's the thinnest material ever built once I say thin it's no height it's width it's length but it's just one atom tall how does one make graphene well take your ordinary number two pencil almost sure why they call them pencils they're made from graphite so you're taking that lead pencil draw it across the page and you have now got some graphite on the page imagine if you'll take a layer of the graphite away then take another layer away and another you retain healing off layers of the graphite until there's just one layer left one atom tall that's graphene it's made up of ordinary graphite a really plentiful cheap material but graphene once you catch on down to the one atom height it's suddenly the strongest material ever measured it's a hundred and fifty times stronger than steel it's almost completely transparent transmits almost 98% of the sunshine that passes through it it's as pliable as rubber you'll stretch it to 120 percent of its size it's highly conductive 150 times more so than silicon it is the only substance we all know of that's completely impermeable to liquids and gas but it weighs almost nothing it has been theorized for many years graphene is but finally in 2004 they need isolated it within the lab now ten thousand patents exist today there are over 25,000 patents let me illustrate for you a number of the potential uses of graphene for computing ultra long life batteries and photovoltaic cells power everything from mobile devices to your home computers that are 100 times faster than today's fastest machines touchscreens liquid displays organic LEDs for your smart phones tablets and TVs super thin smartphone bendable unbreakable how about for the environment ready to">we will eliminate radioactive material and toxic spills water filtration systems for desalinization creating biofuel improve solar cells how about for aviation conductive paint that removes ice from aircraft weight saving inflatable slides and rafts for industry we will improve the electrical effect we will provide lubricants radio emission absorption sound trend users thermal management structural materials faster chemical reactions fluids that increase the efficiency of oil drills how about 4D printing also wondering what 4D printing is aren't you well we all know what 3D printing is that's three-dimensional printing 4D printing is essentially printing on demand upon a change in natural process in humidity change in light suddenly the device prints itself how about for the military body armour for military personnel and vehicles how about for healthcare scaffolds for medulla spinalis injuries blood sugar testing cheaper medical imaging faster and efficient devices that monitor glucose hemoglobin cholesterol DNA sequencing body sensors to live breathing pulse and movement MRI contrast agents implantable medical devices and sensors microbial detection and diagnostic devices drug delivery agents for cancer therapy Bionic devices we will place into living tissues connected on to neurons allowing paralyzed people to maneuver tissue regeneration antibiotics cancer treatments and the way about for fun tennis rackets that are lightweight and powerful already on the market by the way bottom line is that this there is a huge amount of cash being poured into nanotech research risk capital funding has skyrocketed over the past 20 years what does all this mean for private finance it means you are going to require to spend tons of cash on nanotech products the newest greatest stuff how would you wish to shop for genes that you simply never need to wash pretty cool huh how would you wish to shop for the newest tennis racket lightweight more powerful than ever nanotech products are in your future you're gonna want to shop for them meaning creating enough money to be able to do so and recognize that advances in health care as exciting as they're they are not getting to be free so you are going want to tons money for what many of us are calling participatory voluntary healthcare we'll talk more that in an episode to return because you're watching the reality about your future that's it for this video in our next video we explore 3D printing you will see the tech already in use from printing trainers to houses this series is predicated on my ny Times trade book the reality About Your Future the cash guide you would like now later and far later if at any point you've got any questions you'll send them to me
