Pretty interesting story out of America's west coast here. The Colorado-based company, Landslide Solution Inc., has created this tremendous air compressor\nail gun to drive "nails" into unstable hillsides, effectively creating a block of soil on the hillslope, rather than building an unstable retaining wall or letting nature takes it course. Heads up to Dave's Landslide Blog for this one.
See the video.
