Synopsis
A diesel powered lumberjack, the Feller Buncher grabs a tree almost two feet thick, slices through the base, lifts and stacks it onto a pile, in just seconds. Finely balanced, it won't tip over while wrangling tall trees on a mountain slope.The rescue hovercraft is light and portable to get to emergencies quickly. To do that, designers broke the rules by using just a single fan for lift and for thrust, where others use two.Notice the weave up close on your shirt sleeve. It's likely made on a high-speed industrial loom. One strand after another is woven two thousand times per second on a complex, synchronized machine, without breaking a stitch.The remote controlled quadrotor aerial drone has graduated from hobby shop to super spy. A meter wide and weighing less than a kilo, it's not only remote controlled, but programmed to fly and land on its own.
