Impressive and Frightening

This is one of the most impressive (and frightening on several levels) pieces of engineering I've ever seen. When there exists a device that can turn a living tree into logs in under 15 seconds, it is no surprise that deforestation can be a problem. Fortunately, this appears to be a tree farm... for IKEA?

The unbridled and unapologetic efficiency by which this machine performs its function leaves a visceral sensation of both awe and horror. It is distrubingly animal-like. The fact the tree is mostly debarked by the time it hits the ground makes my jaw drop.
