Gordon Link, a diabetic and foot amputee, is not looking to climb Mount Everest, run a marathon, or snowboard off a cliff. I just want to walk without stumbling like Im a drunk, he says. It may not sound like a tall order, but until he was fitted with a prototype prosthetic foot that simulates the bodys natural movements, walking on uneven ground was like navigating an obstacle course. Hitting a low spot of even one inch with my old foot was like a non-amputee stepping into a four-inch hole, he adds. Not good.

When a man with no medical degree and a diagnosis of fatal leukemia builds a cancer-curing machine in his garage, you might think it merely the desperate attempt of a dying man to escape his fate. And youd be right. The weird thing is, it just might work.

The Zero-Emissions One-Wheeled Motorcycle

The Uno accelerates with a simple lean and turns like a street bike on side-by-side wheels

Just before his plane dipped into the clouds above Beijing International Airport two years ago, Ben Gulak caught the last clear view of the sun that he would see for two weeks. On the ground, the 17-year-old, who was on a family trip to China, quickly spotted a source for much of the thick haze hanging over the city: smog-spewing motorbikes. Thousands of them, everywhere. “Right then,” he says, “I decided that I wanted to create an alternative mode of transportation, something clean and compact.”

A Rocket Engine for the Masses

Tim Bendel's off-the-shelf powerplant for the burgeoning private space industry. Watch him discuss it

If were ever going to see a true era of commercial space travel—a day when Virgin Galactic is just another spaceline—Tim Bendel believes we need a better rocket engine. Specifically, something that is to the space industry what the internal combustion engine was to the nascent car industry a century ago: a standard, off-the-shelf option that can power any manner of vehicle, from tourist ship to lunar lander. And it has to be affordable to companies not owned by billionaire Richard Branson.

A Living Air Filter

These filters use plants and fans to clear the air of toxic chemicals

Bel-Air
Cost to Develop: $236,000
Time: 1 year
Prototype | | | | | Product
Your home could be emitting toxic gases. Just ask the victims of Hurricane Katrina, whose emergency trailers, made with glue-laden particleboard, let off so much formaldehyde that the Centers for Disease Control and Prevention warned that residents should spend time outdoors and make relocating to permanent housing a priority. Even in more expensive new homes, the concentration of emissions from things like furniture, carpet and paint can be two to five times as high as it is outdoors. But most air filters only catch particulates such as dust and pollen rather than organic compounds like formaldehyde and benzene, and the filters that do trap those gases need frequent replacement. So Mathieu LeHanneur and David Edwards built an ultra-efficient filtration system that eliminates toxins using natures own hazmat squad: plants.

Ten Times the Turbine

Doug Selsam's Sky Serpent uses an array of small rotors to catch more wind for less money

Sky Serpent
Cost to Develop: $250,000
Time: 9 years
Prototype | | | | | Product
Today’s largest wind farms are the size of small towns, made up of turbines 30 stories tall with blades the size of 747 wings. Those behemoths produce a great deal of power, but manufacturing, transporting, and installing them is both expensive and difficult, and back orders are common as the industry grows by more than 40 percent a year. The solution, says inventor Doug Selsam, is to think smaller: Capture more power with less material by putting 2, 10, someday dozens of smaller rotors on the same shaft linked to the same generator.

A Lifesaving Beacon for Miners

Russell Breeding finds lost miners with the same tech found in guided missiles and the Nintendo Wii

InSeT System
Cost to Develop: $475,000
Time: 2 years
Prototype | | | | | Product
In January 2006, an explosion rocked West Virginias Sago coal mine, trapping 13 miners. Rescuers searched an area 500 feet wide by two miles long and didnt reach the miners until 41 hours after the blast, eventually pulling out 12 bodies and one survivor. Jim Ponceroff, who led a rescue team, says that the biggest challenge in recovering miners is locating them quickly so that engineers can drill a borehole for fresh air and, ultimately, rescue. Sago, like most of the countrys nearly 900 active mines, relied on radios that transmit signals over a thin wire thats easily damaged in a cave-in.

The Indestructible Bridge

John Hillman put a concrete arch inside a plastic case to build stronger, longer-lasting bridges

MAN OF FAITH: John Hillman stands under a test bridge made with his composite beams, which get their strength from a concrete arch inside.  Mike Zicko/HC Bridge Company

Last November, John Hillman stood beneath a bridge built with prototype plastic-and-concrete beams of his own design. Then he signaled for his team to release a nine-million-pound coal train. “You can do all the calculations you want; you can do tons of lab testing. But at the end of the day, you run a heavy-axle coal train over the bridge, and that pretty much tells you whether or not it’s gonna hold,” Hillman says. It didn’t budge.

A Sewage-Proof Suit

Taber MacCallum helps hazmat divers safely explore contaminated waters

Paragon Diving System
Cost to Develop: $1.2 million
Time: 7 years
Prototype | | | | | Product
Diesel oil and raw sewage slowly trickled into Taber MacCallums eyes as he swam toward the sunken research ship hed been called to help salvage. It was 1989, and Hurricane Hugo had devastated Puerto Rico three days before, dumping fuel and municipal waste into San Juan Harbor. As the young diver and analytical chemist worked to raise the ship, the seals on his diving equipment disintegrated in the muck that crept into his helmet. Every time MacCallum exhaled into the putrid water, his helmet let a few drops back in.

Steam Under the Hood

Harry Schoell's engine uses superhot steam to make a cleaner, more efficient car. With video of the inventor demonstrating the engine

The Cyclone

Time: 8 yearsPrototype | | | | | Product
As long as the internal combustion engine has been around, garage tinkerers have been trying—in vain—to best it. But Florida boat engineer Harry Schoell, a lifelong inventor with a portfolio of patents, thinks hes got the answer, in the form of a reinvented steam engine.
