Stephen Walden with his Ergonomic Shovel
When it comes to defining what technology is, you may have heard people say "Heck, even the shovel is an example of technology." That may be true, but it's also an example of technology that has hasn't changed much in a long time. California-based entrepreneur Stephen Walden, however, wants to change that. After getting stiff and sore using a conventional shovel, he set about designing an alternative. The result is his Ergonomic Shovel, that features a rotating second handle in the middle of the shaft.
