Car sharing is often available only in metropolitan areas because it's just not that effective in rural settings. 3-D-printed auto parts have been round for a while, but inventor Jim Kor and a team of fellow engineers has gone a step additional and printed a complete automobile. To that end, the XO laptop has no shifting elements -- no onerous drive with spinning platters, no cooling fans, no optical drive. A couple of hundred dollars spent on digital tuning may give the same energy that hundreds of dollars in engine components may buy. Many of the parts you'll be dealing with once you assemble your laptop are highly delicate to static shocks. Medical researchers are making strides with bioprinting, during 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 making an attempt to determine the right way to grow duplicates of human organs in laboratories in order that they can transplant them into people who need them. This implies two things: First, the Lytro would not need to focus earlier than it takes a photograph. The automobile took about 2,500 hours to fabricate, which suggests it's unlikely to be exhibiting up in your local car vendor's showroom for some time. |
