10 Inventions We're Waiting For

though much has changed since humankind fled the wilderness for civilized comforts, one thing hasn’t: we still clean ourselves with water. yet traditional showers take time, waste resources and don’t necessarily get the job done. instead, we should take a lesson from doctors who sterilize surgical instruments through techniques such as high-pressure, high-temperature autoclaves, ethylene oxide gas and ultrasonic vibrations. while these methods aren’t exactly “people-friendly,” a little research may enable modern humans to step out from under the indoor waterfall and give up the last of our caveman-like ways.
kids’ knees and noggins can be protected with padding and helmets—but how do we safeguard their delicate minds? the answer may lie with augmented reality (ar), a technology that combines sights and sounds of the real world with virtual information. ar eyeglasses could detect inappropriate sights and remove them from view, while ar-enabled earbuds would delete ambient cursing. meanwhile, adults might wear glasses that substitute blessed blank space for roadside billboards, television commercials and the annoying corporate names on most stadiums. professor jie yang of the interact research center at carnegie mellon university recently laid the groundwork for this technology. his prototype digital camera picks out street signs and billboards from a scene and translates their text to another l
the world is complicated, and big decisions can be hard to make. instead of trusting your own fallible human intuition, why not plug the variables of your life into a supercomputer and watch your fate unfold by the numbers? advanced simulation software could generate a slew of parallel lives, each following a different fork in the road: where you live, which person you date or whether you adopt that great dane puppy. the u.s. army already uses tactical simulators to predict the outcome of battles and to fine-tune supply-chain logistics. now, researchers at the institute for creative technologies at the university of southern california are working on the intelligent forces project, with the goal of simulating the behavior of civilian populations—and insurgent forces—on a citywide scale. if
acoustic cloaking shell
long-term exposure to loud noise damages hearing and is associated with an increased risk of heart attack. so what if we were able to step into a portable sphere of pure silence? imagine soundproofed homes perched next to freeways, expanded flight corridors for now-silent jets and quiet slices of heaven for people who work or live in noisy environments, such as city streets, construction sites or crowded coffee shops. noise-canceling headphones already exist- they use an external microphone to detect incoming noise and then generate sounds that are 180 degrees out of phase. the two sound waves cancel each other out—a phenomenon known as destructive interference—but the process only works for low-frequency sound. it’s a good start, but the real deal may be on the horizon. a recent article i
humans invented the wheel- mother nature invented legs. it was only a matter of time before we realized her design was better. the product of this epiphany? a wheelchair that can walk. developed by toyota, the “i-foot” prototype is an 8-ft.-tall bipedal throne that ambles, kneels and climbs stairs on backward-bending, ostrichlike legs. but let’s not stop there. picture a world of legged beds, couches and tables. people could downsize their houses to only two rooms: a storage room that holds the furniture and a main room that shifts to become whichever space is needed. want a living room? have the couch and coffee table walk over. need a beer? call the refrigerator. feel free to mix and match: take a bath while watching television, or cook dinner while using the treadmill. anything is possi
a professor at the university of california san diego recently explained the inexorable physical principles that govern the tendency of everything from rope to proteins, even dna, to form knots. but science trumps nature. materials called electroactive polymers change shape when supplied with electric voltage. cables constructed with cleverly integrated electroactive polymer components could lead to headphones that don’t tangle, as well as to self-straightening extension cords and garden hoses. added bonus: fast holiday decorating. you’ll never have to hunch over a hopeless mass of christmas lights again.
insect force field
insects are important for healthy ecosystems, but they also ruin crops, spread disease and occasionally bite your neck—ouch. clearly, humankind needs a portable device capable of protecting an area from all six-legged critters. an insect force field would allow hikers to wear what they want, sleep outside the tent and come back for a dropped candy bar an hour later and find it whole. harmful pesticides and superfluous food packaging would be a thing of the past—so would lyme disease and west nile virus. sadly, current technology is lacking: researchers consider ultrasonic pest-control devices useless, and bug zappers—while fun to watch—kill the good insects with the bad.
ever had an ipod or camera stolen? the time is ripe for microscopic tags that can be permanently implanted into inanimate objects, so they can be tracked to whichever house/pawn shop/precinct they end up in. prepare for greater peace of mind: with a megatracking system in place, people will think twice before walking off with your umbrella, and airlines will always know exactly where your luggage has landed. technology is almost up to the task. radio-frequency identification (rfid) readers can detect button-size tags from 30 ft.—even through walls. there is a compromise, of course: your privacy. if you can track all of your possessions, chances are good that corporations, governments and tech-savvy criminals can, too. is it worth it? maybe not. but it’d be pretty great to go swimming
cars have it, so why not kids? in an automobile, gm’s onstar system is a computer that monitors car diagnostics such as engine temperature, tire pressure and whether the airbags have deployed. in the case of an accident, the system uses a built-in mobile phone and gps tracker to contact a dispatcher who arranges to send help to stranded motorists. similarly, kid onstar could be packaged into a bracelet or necklace crammed with sensors that monitor location, physiological status and voice stress levels. parents could receive monthly diagnostic checks on exercise levels, notification if children are injured or kidnapped and the assurance that emergency services will be sent the instant a problem arises. while newer versions of onstar allow police to automatically disable a vehicle at the tou

our brains store as memory only a fraction of what we see—the rest is lost forever. so why can’t we save our visual experiences for posterity by recording sights directly from our eyes? photographers would snap impossible shots, eyewitnesses would accurately identify criminals and life’s special moments would be stored, annotated and available for easy reference. a memory recorder might combine two existing technologies: a wearable computer that sorts and stores data (a memory prosthetic) and an implantable micromachine that intercepts and wirelessly transmits electrical activity from the optic nerve (a neuroprosthetic). with every frame of your life cataloged, this ensures you’ll never forget a face again—even if you want to.
