disco_tracy writes "A California inventor has filed a patent for a coffin that screws into the ground vertically. The reason? It greatly reduces excavation labor and burial costs, decreases land use, and opens up more space for burials in unused areas of a cemetery. Writer Clark Boyd also lists 5 other unconventional burial options, including lye, ecopods, GPS devices that track bodies buried without headstones, cryogenics and — my favorite — getting buried in the sky."
