Car sharing is often accessible solely in metropolitan areas because it's simply not that efficient in rural settings. 3-D-printed auto components have been around for some time, but inventor Jim Kor and a staff of fellow engineers has gone a step further and printed a complete automotive. To that finish, the XO laptop has no shifting elements -- no exhausting drive with spinning platters, no cooling fans, no optical drive. Just a few hundred dollars spent on digital tuning can give the identical power that 1000's of dollars in engine elements would possibly buy. Many of the elements you'll be handling once you assemble your computer are highly delicate to static shocks. Medical researchers are making strides with bioprinting, in which they harvest human cells from biopsies or stem cells, multiply them in a petri dish, and use that to create a form of biological ink that printers can spray. For years, researchers have been trying to figure out the way to grow duplicates of human organs in laboratories so that they will transplant them into individuals who need them. This means two things: First, the Lytro doesn't need to focus before it takes a photograph. The vehicle took about 2,500 hours to fabricate, which suggests it is unlikely to be exhibiting up in your local automobile supplier's showroom for some time.
