It's not unlikely that your grandparent used canning jars for their original purpose: canning. But here in the twenty-first-century kitchen, the hard-to-destroy, easy-to-seal jar has become valuable for many more purposes. We love it -- and not just because one of the most popular models is manufactured by aerospace pioneer Ball.
While serving as an army medic during Operation Desert Storm, Richard Schwartz became all too familiar with gunshot wounds, particularly shots to the pelvis and upper legs. Enemies would target that region because body armor doesn’t always cover it. Conventional tourniquets don’t work around the abdomen—it’s impossible to tie them tight enough to cut off blood flow from the aorta. Soldiers with “junctional hemorrhages” may have only a few minutes before they bleed to death.
For the better part of Frank Will’s life, he has been consumed with improving engine performance. He started racing motorcycles as a teenager in Germany in the 1970s, winning a world championship race in 1991, and later became an automotive engineer at Ford in Australia. When he left his job in 2008, he applied his passion to a new endeavor: Over7, a system that by redirecting and then heating an engine’s oil, cuts gas consumption by 7 percent and emissions by up to 30 percent.

Taking a shower draws more water and more energy than any other daily household activity. Low-flow showerheads save only a little of both, typically at the expense of comfort. That’s because they let the hot water—and all the heat energy it contains—go down the drain.
Spring-loaded skates that give hockey players a boost

David Blois manages condominium properties near Toronto, but at any given time he's usually also working on several inventions—a solar-powered smoke detector, say, or an age-spot-erasing skin cream. In 1998 he was ice skating at his local rink when an idea popped into his head: a hockey skate that used springs to harness a skater's kinetic energy. "It's really hard to invent something new," Blois says. "As I researched patents, I got more excited. No one had ever tried this before."
During a regular fishing season, most lobstermen can afford to check and rebait their traps only every three or four days. Each run to the traps can cost as much as $600 for fuel and take 18 hours of work. But three or four days can be more than enough time for lobsters to eat the chunks of herring or mackerel that serve as bait. With no bait left, lobsters don't enter the trap and fishermen are left with a smaller catch. Thus, the millions of traps that dot the Atlantic from Newfoundland to North Carolina remain empty about half the time.
Vince Stuart, the owner of a Nova Scotia company that makes winches, gantries and other fishing-boat rigging, first heard about the lobstermen's problem from his clients on the docks in 2003. He soon began building the Bait Savour, a device that would release an extra supply of lobster bait a few days after a trap was laid. It allows the lobstermen to check their traps less frequently (about once every five days instead of every three or four), saving time, labor and fuel.

While experimenting with new applications for Kinect’s real-time, 3-D imaging capability, San Francisco freelance coder Robert Hodgin discovered a way to make people’s bodies appear puffy and grotesque onscreen. The Kinect uses a near-infrared camera and sensors to produce a 3-D depth map that indicates a person’s spatial location. Its depth camera is offset from the camera that collects color data, which causes the depth map to produce shadows on the sides of the person in view.

When Kelly Anderson shed her arm cast two months after a wrist operation, her joints were so stiff she couldn't turn a doorknob. She didn't fully recover for another four months. Daniel Amante suffered similar post-cast complications after he injured his knee; Amanda Harton watched her soccer teammates struggle following various injuries; and Clara Tran saw even greater suffering among the frail patients in the nursing home where she volunteered.
A set of contact lenses that turns the wearer's field of vision into a screen

After two decades as an electrical engineer, Randy Sprague quit his job in 2008 to start a solar power company. He had been planning the venture for years, saving up, getting his wife's blessing. But then one morning while taking a shower, he had a brainstorm for an entirely different idea: contact lenses that could act as part of a wearable display. Users could instantly augment their view with information—say, the price of an antique in a store or the species of a tree in the forest—or transform their field of vision into a virtual videogame screen.
