Yesterday, in Mesopotamia, the engineer Dr. Kurhitti-mushtesher invented a new device that he named "Wheel". According to the scientist, an innovative circular shape - that has been immediatly patented - makes the wheel rotation around the axle smoothly compared to reference state-of-the-art square shape device. The device uses innovative materials as bones and the recently discovered Obsidian combined with high-tech tools and technologies to polish the stone surface. It is not clear at the moment which consequences this discovery will have for our world and if someone may be interested in licencing it.
