3D-Printed Heart Could Be Beating in 10 Years An ambitious 3D-printed heart project aims to make a natural organ replacement for patients possible within a decade. But the researcher heading the effort also believes 3D-printing technology must harness the self-organizing power of biology to get the job done. The idea of a 3D-printed heart grown from a patient's own fat stem cells comes from Stuart Williams, executive and scientific director of the Cardiovascular Innovation Institute in Louisville, Ky. His lab has already begun developing the next generation of custom-built 3-D printers aimed at printing out a complete heart with all its parts -- heart muscle, blood vessels, heart valves and electrical tissue. 10 Amazing Parts Grown Outside the Body "We can print individual components of the heart, but we're building next-generation printers to build the heart from the bottom up," Williams said. "I took a step back and looked at my colleagues, and said, 'Why don’t we build it like a large airplane?'" Most Amazing Medical Breakthroughs

The first approach would include, for example, how to utilize your vehicle for helping you to stay alive, advice on whether you should try to hike out back to civilization or not, and so on. There's very little of that kind of material here (at least so far). The focus here is on living in the wilderness in a primitive fashion. That means without guns, axes, other manufactured items, log cabins, and so on. Of course, all the material presented here can aid you in both staying alive until help arrives, as well as in living in the wilds in a primitive or semi-primitive fashion, whether it be as a hobby or in a conscious effort to live close to the land.
