Car sharing is usually available only in metropolitan areas as a result of it's simply not that effective in rural settings. 3-D-printed auto parts have been round for some time, but inventor Jim Kor and a group of fellow engineers has gone a step further and printed a complete automotive. To that end, the XO laptop computer has no moving parts -- no laborious drive with spinning platters, no cooling fans, no optical drive. A number of hundred dollars spent on electronic tuning may give the same energy that hundreds of dollars in engine parts may buy. Many of the parts you may be dealing with once you assemble your computer are highly sensitive 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 kind of biological ink that printers can spray. For years, researchers have been making an attempt to determine the best way to develop duplicates of human organs in laboratories in order that they'll transplant them into individuals who want them. This implies two things: First, the Lytro would not have to focus earlier than it takes a photo. The car took about 2,500 hours to fabricate, which means it's unlikely to be exhibiting up in your local car vendor's showroom for a while.
