Seen over on Core77's blog is this awesome invention. Basically, a minor electrical current runs through you and your handy table saw. When your finger approaches proximity to the blade, the current is cut/completed or whatever, and enacts a stopping mechanism that destroys the blade and mechanism, yet saves your finger. Here's the proof:
While not a substitute for learning proper safety techniques with power tools, every school's woodshop should have these.
Tool manufactures, if not already done so, need to license it and add it as a feature on their saws. Looking at the web site, it seems as if SawStop is going about doing business differently. I think it's not always building the better mousetrap, it's building components that enhance the mousetrap. Apple made the iPhone. Thousands of developers make iPhone applications. They don't remake the iPhone. Same with Google Gadgets (Go, go, Google Gadgets!), FaceBook, etc.
I would like to see another test, this one using a hot dog that is flicked into the blade. Something a little faster to test the reaction mechanism. I don't think a majority of saw accidents are done by normal operating procedures.
