The EksoVest looks like the future of construction and tools. Well, at least as long as humans do construction work (before the robot revolution of course *smile*). With this mechanical strap-on device working with big tools is much easier then ever before. Check it out in the video.
I am not really convinced by the MULE (Material Unit Lift Enhancer) though. It looks quite slow. Sure, it makes the job easier for the workers in a sense that they have to lift less. But it feels like two guys could build half a wall in the time the MULE takes to put down two stones.
But, we will see which ones of these inventions will make it.
