Car sharing is often accessible only in metropolitan areas because it is simply not that efficient in rural settings. 3-D-printed auto parts have been round for some time, however inventor Jim Kor and a team of fellow engineers has gone a step further and printed a complete car. To that finish, the XO laptop has no moving parts -- no exhausting drive with spinning platters, no cooling fans, no optical drive. A few hundred dollars spent on digital tuning can give the identical power that thousands of dollars in engine components would possibly buy. Many of the components you'll be handling if you assemble your pc are extremely delicate to static shocks. Medical researchers are making strides with bioprinting, by which they harvest human cells from biopsies or stem cells, multiply them in a petri dish, and use that to create a type of biological ink that printers can spray. For years, researchers have been attempting to determine the way to grow duplicates of human organs in laboratories so that they'll transplant them into people who want them. This means two issues: First, the Lytro would not must focus earlier than it takes a photo. The car took about 2,500 hours to fabricate, which implies it is unlikely to be showing up in your native automotive dealer's showroom for some time.
