Jul 30, 2013 TACTICAL TUESDAYS Every Tuesday, we will be posting up a video or link to something tactical... Could be about armored cars, hunting, or maybe even a machine that lets you climb walls like spiderman?!? Feast your eyes on PVAC (Personal Vacuum Assisted Climber) PVAC was designed for a national competition held by the U.S. Air Force by a group of students at Utah State University called the "Ascending Aggies" They took 1st place and got a grant for $50k.The Air Force liked the prototype so much that they are investing an additional $100K towards further development of this product. My guess is the first thing they will do is figure out how to make it silent??? Looks like Dyson and the U.S. Air Force might be teaming up way sooner than anyone could have imagined.
