HTC Vive: Walk in a Virtual World

HTC Vive: Walk in a Virtual World

Virtual reality is not that real if you can't walk around and interact with the world. The HTC Vive is the first virtual-reality system to offer that level of immersion. It uses two base stations to track your position as you move around a room. Hand controllers let you interact with objects in the virtual world (and throw them across the room, if you want). The Vive is powered by the new digital gaming distribution service, Steam, which was built by gaming powerhouse Valve. For now, Vive is still a developer edition, but HTC promises that the headset will hit shelves before the end of the year.Jonathon Kambouris

ZTE Spro 2: A Wireless Projector and Hotspot

Wiring a projector can quickly turn into a tangled mess with video cables, power cords, and ethernet cables. The ZTE Spro 2 kills cables altogether. It's a portable 4G LTE hotspot, Android device, and wireless projector in one. The size of a book, the Spro 2 has a 5-inch touchscreen that runs the full Android OS, meaning you can project any app (such as Netflix and Instagram). The device can also provide Internet for up to 10 devices. From $400Jonathon Kambouris
GoPro Hero4 Black: The Smallest 4K Action Camera

GoPro Hero4 Black: The Smallest 4K Action Camera

The most popular action camera now shoots 4K video—and it's still just the size of a Zippo lighter. The Hero4 Black records ultra-high-definition video at 30 frames per second and HD video at 120 frames per second—fast enough for detailed slow-motion. The camera pairs with an app that lets users frame shots or review footage on the go. The GoPro Hero4 Black has also been used to film parts of the feature film The Martian, and if it's good enough for that, it's probably good enough for you. $500Jonathon Kambouris
Meccano Meccanoid G15 KS: A DIY Robot You Can Talk To

Meccano Meccanoid G15 KS: A DIY Robot You Can Talk To

The Meccanoid G15 KS is a build-it-yourself robot made from 1,223 parts that can rove around, crack jokes, and respond to questions. It's controlled by a tiny computer and stands nearly 4 feet tall when constructed. Users operate Meccanoid using a voice-command system. They can teach it new moves by moving its limbs like a puppet or using a drag-and-drop avatar in its companion app. Makers can rebuild Meccanoid into any number of forms, including a scorpion, raptor, and more. $400Jonathon Kambouris
Philips Fidelio B5: Surround Sound in a Sound Bar

Philips Fidelio B5: Surround Sound in a Sound Bar

The Fidelio B5 looks like a regular sound bar, but the ends detach, so you can move them around the room, creating surround sound without the wires. Philips embedded a calibration system in each, so volume and balance self-adjust to provide the best sound possible. The two wireless speakers can also be moved to different rooms, morphing into portable Bluetooth speakers. That means you'll spend your next movie night engulfed in sound rather than huddled around the television. $900Philips
Red Epic Dragon: A Camera Built for the Future

Red Epic Dragon: A Camera Built for the Future

The Epic Dragon by Red captures more detail than any other camera in the world. It's the first to include a 6K image sensor—a higher resolution than most monitors can display—giving filmmakers more flexibility while editing. The quality is so good, scientists recently shuttled one to the International Space Station to film experiments. Head to NASA's YouTube page for unbelievable footage from the ISS. From $24,000Red Digital Cinema Camera Company
Nvidia Shield: Blazing-fast Media Console

Nvidia Shield: Blazing-Fast Media Console

There's nothing worse than having your movie marathon rudely interrupted by image stuttering or buffering. That won't happen with the Nvidia Shield. The first 4K streaming set-top box employs the world's fastest mobile chip, Tegra X1, and gigabit ethernet to ensure it never hits a speed bump. It also doubles as a gaming console and runs on Android TV—so thousands of movies and games are already available. From $200Jonathon Kambouris
IMAX Laser: Best Way To Watch A Movie

IMAX Laser: Best Way To Watch A Movie

IMAX has always offered a fully immersive cinema experience, but its projection system lacked a certain clarity. IMAX Laser fixes that problem. It provides the highest contrasts (and color range) of any projector ever. It also doubles the number of surround sound speakers in the theater to 12.IMAX
Sphero BB-8 A Star: A *Star Wars* Droid You Can Own

Sphero BB-8 A Star: A Star Wars Droid You Can Own

When The Force Awakens' trailer debuted this summer, the movie's star robot, BB-8, rolled onto the screen and into our hearts. Now, it's rolling into our living rooms. This 4-inch toy version has three modes: driving, which lets users direct the BB-8 using a joystick on your smartphone screen; holographic messaging, which uses the phone's camera and an augmented-reality engine to turn videos into Star Wars holographic messages (like in A New Hope); and patrol, which automates BB-8, documenting any collisions in its app. $150Jonathon Kambouris
Samsung SUHD Series: A 4K Television For The Masses

Samsung SUHD Series: A 4K Television For The Masses

The Samsung SUHD series matches the quality of sharpest TVs on the market—but at half the price. The trick is in the nanocrystals, which are layered on cheap-to-produce blue LEDs and allow more backlight to shine through to viewers. That means sharper contrasts, more­-accurate color, and brighter images fill the screen. The SUHD series also uses an eight-core processor to power the TV's smart operating system, letting users access Netflix, YouTube, and Playstation Now without the need for a set-top box. From $4,500Samsung
Sling TV: TV For Cord Cutters

Sling TV: TV For Cord Cutters

Sling TV is a subscription service that lets users watch live and on-demand TV shows on Amazon Fire TV, Roku, Xbox One, Mac, Windows, iOS, Android, and some smart TVs. Popular channels like ESPN, CNN, and Cartoon Network can be streamed from anywhere in the U.S.—meaning the whole family will have something to watch. There are no DVR capabilities with Sling, but the upside is there are also no contracts. Starts at $20 per monthDish Network
Star Wars Battlefront: Biggest Videogame Space Battle

Star Wars Battlefront : Biggest Videogame Space Battle

For decades, Star Wars fans could only imagine what it might be like to battle in the snowy tundra of Hoth or the deserts of Tatooine. In Star Wars Battlefront, they can finally play out their favorite scenes (or rewrite history in this fictional universe). The game allows up to 40 players at a time, meaning there's plenty of war zone action. Weapons include lightsabers, X-wings, AT-ATs, and speeder bikes. Oh, yeah. And you can play as Luke Skywalker and Darth Vader. May the Force be with you. $60Electronic Arts
Boeing 777X: Ultra-Efficient Folding Wings

Boeing 777X: Ultra-Efficient Folding Wings

Wing size matters—bigger wings generate greater lift, which can improve an airplane’s fuel efficiency. With a 235-foot wingspan, one of the largest in the industry, Boeing’s new 777X twin-engine airliner will undercut its competitors in both fuel consumption and operating costs per seat. Thanks to their carbon-fiber composition, the wings are both strong and flexible—and the tips even fold up so today’s airports can accommodate their wider span.Courtesy Boeing
Rosetta: Comets Finally Get Their Closeup

Rosetta: Comets Finally Get Their Closeup

For the first time in history, humans put a spacecraft in orbit around a comet and, in another first, landed on it. The European Space Agency's Rosetta spacecraft traveled 10 years and nearly 4 billion miles to Comet 67P/Churyumov–Gerasimenko. Once it arrived in November 2014, the Philae lander descended to the comet's surface, bounced, and came to rest in a dark area near the edge of a crater. Unable to recharge through its solar panels, Philae went into hibernation—but not before transmitting data about 67P's makeup, internal structure, and wealth of organic molecules. As the comet hurtled toward the sun, the Rosetta orbiter stuck with it, observing as its frozen gases warmed and escaped into space. This data should provide valuable clues to the history of our solar system.Courtesy European Space Agency
Sikorsky Aircraft S-97 Raider: Fastest Helicopter

Sikorsky Aircraft S-97 Raider: Fastest Helicopter

Designed by Sikorsky as an attack and transport vehicle for the U.S. military, the S-97 Raider has a top speed of 276 miles per hour, nearly twice that of a conventional helicopter. It's also quieter, can climb higher, has a smaller turning radius, and—thanks to a rigid coaxial rotor and pusher propeller—is more precise and maneuverable. The full-size vehicle, which can carry two crew members and six soldiers, took its maiden flight this May.Courtesy Sikorsky Aircraft
DHI Parcelcopter: Real-World Drone Delivery

DHI Parcelcopter: Real-World Drone Delivery

In late 2014, shipping company DHL began making several deliveries a day to the remote North Sea island of Juist, Germany, dropping off medical supplies and other necessary goods. And for the first time in a real-world program, autonomous flying drones performed the work. The Parcelcopters persisted even in high winds, rain, snow, and cold temperatures. The pilot program proved that, in case of emergency, deliveries needn’t rely on pre-scheduled, human-operated services.Courtesy DHL
New Horizons: Voyage To Pluto

New Horizons: Voyage To Pluto

When New Horizons launched almost 10 years ago, our sharpest image of Pluto was a fuzzy ball. This summer, the mission's flyby captured stunningly clear photos of the dwarf planet—and the never-before-seen heart-shaped area on its surface. In addition to cameras, New Horizons carries the most comprehensive suite of instruments ever sent to an unexplored world. The probe will study Pluto's atmosphere and composition, and teach us more about how our solar system formed.Courtesy NASA
X-Avionics Xavion: The App That Will Make Emergency Landings

X-Avionics Xavion: The App That Will Make Emergency Landings

If its pilot passes out, an airplane is in serious trouble. But the new Xavion app from X-Avionics might save it. Used in conjunction with an autopilot interface, the app can take over a craft's controls and guide it to a safe, albeit hard, landing. For an active pilot in an emergency situation, the app provides routes and beacons to the nearest airport, acting as a virtual co-pilot.Eric Adams

TriFan 600: Vertical Takeoff In A Civilian Airplane

For the executive who has everything, now there's the TriFan 600, an airplane and helicopter in one. The six-seat concept will use three ducted fans to rise vertically like a helicopter. Once it's airborne, two fans will pivot to generate forward momentum and provide lift so it can fly like a conventional jet. This August, after three years of development, XTI announced a crowdfunding campaign, which will cover a portion of the program's costs and give potential buyers a chance to back it.Image courtesy XTI Aircraft Co.

New Shepard: A Manned Rocket For Tourists

Blue Origin's launch of New Shepard in April marked the first successful test of a vertically launched vehicle to lift tourists and researchers into suborbital space. The crew capsule separated from its booster, as planned, and parachuted safely back to Earth. The booster is designed to be reusable too, though a hydraulics failure prevented it from sticking the landing. Blue Origin has made New Shepard's BE-3 engine available for licensing, which means other companies could also use it to get off the ground.Image courtesy Blue Origin

Solar Impulse 2: Longest Solar-Powered Flight

Solar Impulse 2 has flown past a few world records in its quest to circumnavigate the globe. By spending nearly five days in the air this summer (117 hours and 52 minutes, to be exact), the plane made the longest nonstop flight by a solar-powered aircraft. Piloted by co-creator André Borschberg, it was also the longest solo flight ever. During the day, 17,248 solar cells provided power, and the airplane stored energy in lithium-polymer batteries to stay aloft through the night.Image courtesy Solar Impulse

CICADA: Swarming Micro-Drones

Picture a paper airplane made of circuit boards, and you've just conjured a Close-In Covert Autonomous Disposable Aircraft (CICADA)—an inexpensive, 2.5-ounce glider developed by the U.S. Naval Research Laboratory. Dropped from midair and guided by a GPS system, the micro-UAV can adjust flaps on its wings to crash-land within feet of a target located miles away. In swarms of dozens, or even hundreds, CICADAs could serve as cameras, microphones, sensors, and weapons detectors, or form a communications network.Image courtesy Naval Research Laboratory

August Home Smart Lock: Never Lose Your Keys Again

The August Smart Lock unshackles your home from the tyranny of physical keys. The 3-inch cylinder fastens to the back of an existing deadbolt, leaving the outside appearance of your door unchanged. Once attached, a Bluetooth signal from your smartphone can flip the mechanism to unlock the door. A guest with a smartphone and an August app can enter once you've granted them access. No more passing out hard-copy keys, which are much harder to revoke—and easier to lose. The Smart Lock lets you pick days and times for guest entry, so the dog walker can get in only during lunch hours, or your weekend Airbnb guests lose access once their stay is over. If your guests don't have smartphones, a Wi-Fi add-on allows you to buzz them in remotely. Plus, you can set the Smart Lock to bolt automatically every time the door shuts. And should anything fail, the old key still works. $229, plus $50 for remote connectivityImage: Jonathon Kambouris

Turing Phone: Hack-Proof And Shatter-Proof

With just a single port and waterproofing inside and out, the Turing Phone is designed to be indestructible. For the shell, the company uses an alloy dubbed "liquidmorphium." Because the molecules in liquid­morphium are arranged amorphously, rather than in the rigid structure of metals, the alloy is less prone to bending or breaking. The software is designed to be indestructible too. While no system is truly hack-proof, Turing has made breaching their flavor of Android so computationally expensive that they think hackers won't bother trying. And when users dial other Turing Phones, the calls are fully encrypted end to end—no third-party authentication necessary. $740Image courtesy Turing Robotic Industries

Peerio: Easy, Secure Messaging

In our post-​Snowden world, secure messaging is ever more appealing. The standard encryption method is PGP, or "Pretty Good Privacy." It uses several layers of encryption to ensure messages can be read only by the intended recipient. But PGP can be tricky to set up. Enter Peerio, which provides easy-to-use PGP-level encryption for messages and file storage. Just download the software, have your would-be communicants do the same, set up a secure pass phrase, and chat away. Secretly. FreeImage courtesy Peerio

Drone Shield: Ears, Not Eyes, In The Sky

At the Boston Marathon this year, the DroneShield team worked with city police to deploy 10 detectors that listen, rather than look, for potentially dangerous airborne threats delivered by drone. The unit cross-​references audio it picks up with a library of drone sonic signatures, and sends an alert if it finds a match. DroneShield has installed its ears in the sky around office buildings, prisons, airports, and private homes.Image: Jill Shomer

BaDx: Smallest, Safest Anthrax Detector

Anthrax, a bacterial disease of grazing animals, can be a deadly terrorist tool. Now Sandia National Laboratories and security-technology company Aquila are making it simple to detect. They're producing a credit-card-size lab-on-a-chip that's akin to a pregnancy test: Inject a sample and wait a few hours for a line to appear. Because the test is portable, samples won't accumulate in labs—which is a security risk. It will help ranchers around the world detect the disease in their livestock. Aquila, which is producing the tests in partnership with Sandia, began shipping units earlier this year and plans to adapt the technology for other bacteria like E. coli.Image courtesy Aquila

NYPD DAS Mobile: The App That Keeps Cops Safe

Relaying 911 information to cops on the beat—by radio—hasn’t changed in decades. But there’s only so much intel dispatchers can convey that way. This year, the New York City Police Department—the largest force in the United States—began sending ancillary data to some cops via smartphone. It’s the first police force in the country to do so. The app is secure, requiring a PIN code and an ID scan to log in. Cops get background intel on prior arrests and outstanding warrants at the dispatched address, or helpful details such as whether burglars typically enter it by the back door. For an officer on the street, such extra information can be lifesaving.Image courtesy NYPD
Tesla Motors Powerwall: Now You Can Supercharge Your Home

Tesla Motors Powerwall: Now You Can Supercharge Your Home

You've invested in solar panels to harvest energy from the sun, but without daisy-chaining an array of car batteries, you've got no way to store it. With the Powerwall, Tesla used its expertise manufacturing lithium-ion batteries for electric vehicles to provide a sleek alternative. The 210-pound wall-mounted battery can store surplus energy from solar panels. But it can also automatically bank electricity from the grid during off-peak times, when rates are lowest. That way you can power your home—or charge your Model S—for pennies even when electricity is in highest demand. The company makes a 7 kWh battery for daily use, and a 10 kWh version that can double as a backup generator. From $3,000Courtesy Tesla

Stack Downlight: A Bulb That Gets To Know You

What if your lights could understand their surroundings? Stack added occupancy- and ambient-light sensors to its LED Downlight bulbs. The result is a lightbulb with smarts: It can turn off when you leave a room and recognize when it's morning in order to wake you up. To protect you, the system can even mimic your lighting habits when you're away on vacation. Don't like the schedule? You can custom-program it yourself with a companion app. $150 (for a starter pack of two bulbs and a hub; $60 for each additional bulb); ships in December.Courtesy Stack

Dyson Humidifier: The Ultimate Clean Machine

Humidifiers can often be breeding grounds for bacteria. But that doesn't mean humans have to live with bone-dry air. Dyson's new humidifier zaps bacteria with ultraviolet light, killing 99.9 percent. It also uses the same "air-multiplier" technology as the company's fans, to ensure thorough room coverage. It's the first humidifier to earn an asthma and allergy-friendly certification from the Asthma and Allergy Foundation of America. $500Courtesy Dyson

Briggs & Stratton EXi Series Engine: Never Change Your Oil Again

Briggs & Stratton EXi Series Engine: Never Change Your Oil Again

Manufacturers recommend you change your lawn mower’s engine oil every 25 hours of use. To eliminate that messy hassle, Briggs & Stratton built its new EXi Series Engine. The engine is designed to run cooler because oil breaks down more slowly at low temperatures. (It also features an improved air-filtration system to run cleaner.) Rather than change the oil, just top off periodically to maintain proper levels. In a year, you’ll end up using 73 percent less oil.Courtesy Briggs & Stratton

Channellock Rescue Tool: React Like A First Responder

Police officers and firefighters aren't the only ones who have to grapple with emergencies. So why shouldn't homeowners use the same multitool they do when confronted with a storm or fire? The Rescue Tool combines five tools, including a spanner wrench to tighten and loosen hose couplings, a prying tip that can help jimmy open a stuck window, and cutting edges that can snip wire. $50Courtesy Channellock
Whirlpool HybridCare Heat-Pump Dryer

Whirlpool HybridCare Heat-Pump Dryer: A Hybrid For Your Hamper

The average clothes dryer can consume as much energy per year as a refrigerator. To balance the scales, Whirlpool built a ventless heat-pump model. Instead of releasing hot, moist air, the HybridCare condenses the water internally. The dry air is then recirculated—reducing energy costs by 40 percent over standard dryers. $1,799Courtesy Whirlpool

Preventing the Next Pandemic

A new vaccine usually takes six to 10 years to go through clinical trials. The Ebola vaccine took only 10 months. When the West African outbreak was declared a global health emergency in August 2014, the World Health Organization fast-tracked the process. The vaccine, made by swapping proteins from Ebola into another virus, triggers an immune response that protects people from contracting the actual disease. To test its efficacy, health workers in Guinea used a “ring strategy” around the 100 confirmed Ebola cases in the country. First, doctors vaccinated roughly 4,000 adults who had come into contact with the infected patients. None got Ebola. For a control group, they vaccinated another approximately 3,500 people three weeks after identifying the latest infection. Only 16 contracted the disease. “The ring strategy hinges on vaccinating all contacts of a recently confirmed case, and their contacts in turn, virtually creating a firewall and stopping transmission in its tracks,” says Marie-Paule Kieny, WHO’s assistant director general for health systems and innovation, who led the R&D. The Ebola vaccine showed that scientists can develop and deploy lifesaving drugs quickly—in the future, preventing other diseases from going global.Image: Jonathon Kambouris

Micra: The World's Smallest Pacemaker

Doctors surgically implant most pacemakers in the chest and run wires from the device to the heart. The vitamin-size Micra can be threaded through the femoral vein into the heart with a catheter. Tines then attach to the heart to deliver electrical impulses directly. The battery lasts more than 10 years, and when it’s depleted, doctors can disable the device and insert another nearby. So far, the success rate in trials is 100 percent.Jonathon Kambouris

Human Epigenome Maps

June marked the release of the first map of the human epigenome: the chemical markers that tell your DNA what to express when. “Think of the genome as the hardware in your computer and the epigenome as the software,” says Joseph Ecker, director of the institute’s genomic analysis laboratory. Such a map will help scientists see what causes some cells to become liver cells and others heart cells—or malignant cancer cells. Understanding these mechanisms could enable scientists to reprogram them for bioengineering or to reveal new triggers for disease.Image compiled by Ryan Lister.

Teixobactin: First New Antibiotic In Nearly 30 Years

Teixobactin: First New Antibiotic In Nearly 30 Years

Teixobactin can fight resistant strains of bacteria such as Mycobacterium tuberculosis, which (as its name suggests) causes tuberculosis. And because it binds to bacteria on two target regions, in contrast to most antibiotics' one, bacteria are less likely to develop resistance to it. The drug candidate is still in the pipeline and works for only certain bacteria, but one of them is invasive MRSA, which some 75,000 Americans contract every year.NovoBiotic
Xoft: Targeted Cancer Radiation In One Go

Xoft: Targeted Cancer Radiation In One Go

Radiation therapy for breast cancer can require eight weeks of near-daily trips to the hospital. A method called intraoperative radiation therapy takes less than 12 minutes total. During a patient’s tumor-removal surgery, a radiation oncologist delivers a single, concentrated dose of radiation. It aims to kill any malignant cells the surgery might have missed, and helps prevent cancer from returning during recovery. Two recent clinical trials have found it to be as effective as conventional radiation. Plus, a patient experiences fewer side effects and is able to get back to normal activities much sooner.iCad

Aim: A Monitor With Muscle

Aim: A Monitor With Muscle

For gym rats, scales can show body weight, but not muscle condition or body fat—important measures of fitness. Aim does both. When placed on the skin, the device sends a weak electric current through the body. Since muscle and fat have different resistances, it can tell them apart. Aim determines the strength of a muscle relative to its size too, so you can see the direct effects of a workout (or a lazy streak). A medical-grade version can monitor the impact of degenerative diseases like muscular dystrophy or amyotrophic lateral sclerosis (ALS). $149Jonathon Kambouris

Periscope: A Broadcast Network Of Your Own

The cameras in our pockets have granted amateurs all sorts of powers to reinvent themselves—first, as photographers and then as YouTube stars. Now with Periscope, anyone can become a broadcaster as well. The app makes live streaming events like the Black Lives Matter protests, raging wildfires, or even office antics as simple as pressing a button. The stream is accessible to anyone who also has the app installed on their mobile device. In the hands of journalists, Periscope has broadcast videos from the Syrian refugee crisis, putting a human face on a global crisis that for many is happening out of sight. Inevitably, it has also prompted privacy concerns and put more than one business model in jeopardy: Periscope was a popular way to illegally broadcast this year's expensive pay-per-view boxing match between Floyd Mayweather Jr. and Manny Pacquiao.

It also has Cortana, Microsoft's virtual assistant (think Siri for the Windows set), which can schedule meetings, check weather, or do Web searches all with a simple voice command. The OS runs on desktops, laptops, touchscreen tablets, and phones—making it even easier to switch between devices or use tablet-laptop hybrids. Free Upgrade.Jonathon Kambouris

Albedo100 Light-Reflective Spray: Paint That Can Save Your Life

Albedo100 Light-Reflective Spray: Paint That Can Save Your Life

When it comes to safety, staying visible at night is critical for runners, walkers, and cyclists. That's why Swedish startup Albedo100 has developed a reflective spray that can be applied to clothes and bike parts. The spray is invisible during the day but shines like a highway street sign at night when it comes under the glare of headlights. The spray is benign, so it doesn't damage materials or hurt your skin, and lasts about a week before wearing off. There's even another version of the spray that's safe enough to put directly on your pet's fur. Albedo100 released both versions of the spray earlier this year, and a third that works especially well on metals will be out by the end of the year. It also collaborated with Swedish carmaker Volvo to market the spray under the name Life Paint, which they hope to one day sell in the United States. Never stress over Halloween night again. $19Jonathon Kambouris
Stower Candle Charger: Charge Your Phone With A Flame

Stower Candle Charger: Charge Your Phone With A Flame

The Candle Charger by Stower uses an open flame to charge your mobile device. Here's how: You fill a small, specially constructed pot with water, place it on a stand, and set it over a burning fuel-canister candle. A USB cable attaches to the pot, providing a point of connection for your device. As the water boils, the temperature difference between the water and flame creates an electric current that charges your phone. It's handy in the field but also in power outages. Plus you can then tell someone that you charged your phone with fire—because you did. $100Jonathon Kambouris
Voormi Fall Line Jacket With Core Construction: The Only Jacket You'll Need

Voormi Fall Line Jacket With Core Construction

Unpredictable weather in the backcountry means you have to carry many different layers to deal with the elements. The Voormi Fall Line jacket does away with that. This wool zip-up keeps you warm and comfortable in cool weather but also keeps you dry if you get caught in the rain. The Colorado company calls this Core Construction technology. It knits water-resistant material within the wool into a single layer. This makes it possible to have water-resistant clothes in virtually any material, including cotton and nylon. Voormi released the jacket this fall. From $400Jonathon Kambouris

A thumb-size "tracer'' clips to your club and, as you swing, records 1,000 samples of movement per second and sends them to your phone. The resulting 360-degree 3D image reveals club speed, attack angle, and more. It also records and saves each swing so you can compare strokes as you go along and track your improvement. $250Courtesy Epson
Dainese D-Air racing Misano Suit: Failproof Motorcycle Airbag Suit

Dainese D-Air Racing Misano Suit: Failproof Motorcycle Airbag Suit

Motorcycle airbag suits and jackets have been around for years and typically require a tether, attached to the bike, to deploy. That’s a problem if you’re not thrown from the bike during a spill, and if they don't deploy quick enough. The D-Air is the first one in the U.S. that doesn’t require a tether. The suit uses a suite of sensors that detects movement of the body or an imminent crash to trigger airbag deployment. This all happens in just 30 milliseconds. Although it’s been available in Europe since 2012, it just reached the U.S. in September of this year. $2,500Courtesy Dainese
Uvex Snowstrike VT Goggles: Fighter-Pilot Goggles for Skiers

Uvex Snowstrike VT Goggles: Fighter-Pilot Goggles For Skiers

Skiing over uneven terrain with obscured vision isn't just annoying, it's dangerous. The Snowstrike VT Goggles make it a problem of the past by using the same technology found in fighter-pilot helmets. The goggles have sensors that gauge the intensity of outside light and send signals to LCD crystals inside the lenses to change the shade accordingly. In a tenth of a second, the tint morphs to purple, blue, red, or clear. So while flying down slopes at high speeds, and in and out of shade, the wearer will never have a momentary lapse of clarity. The tint can also be changed manually. $500Jonathon Kambouris

MSR Guardian Purifier: Drink Water From A Mud Puddle

The U.S. military asked backcountry outfitter Mountain Safety Research (MSR) to create a device that could protect troops from waterborne illness anywhere they deploy. The company came up with the Guardian Purifier, which uses medical-grade fibers to block out dangerous pathogens, such as bacteria, protozoa, and viruses, along with particulate matter like sediment and silt. Also, the device never requires a cleaning: It uses about 10 percent of the water it pumps up to flush out the blocked contaminants. Now it's available to you.

BMW 2016 7 Series: A New Wave In Driving

No longer will fumbling with a cellphone or reaching for a radio dial dangerously distract drivers. In October, BMW debuted the world's first-ever gesture control in a car, allowing drivers to answer calls, use navigation, and adjust audio, all with conductorlike hand waves. That makes everyone safer. It also hints at the potential for hands-free driving. If that weren't innovation enough, in U.S. models, BMW also took up to 190 pounds off the car's weight, and improved fuel efficiency, by using carbon fiber in the chassis. That helps make the frame stiffer, which enhances performance. Luxury details also make the car feel like it belongs in a pricier class: Massage seats for rear passengers are helpful on long rides, LEDs in the moon roof mimic a starry sky, and programmable scents, like "woody," emanate from the dash. $81,300Image courtesy BMW

Amazon Echo: HAL For Your Home

Amazon Echo: HAL For Your Home

For a long time, artificial intelli­gence existed only in science fiction. Then it started to creep into industrial computers and even phones. Now, it's coming to your home—and it's coming in the form of a speaker. The Amazon Echo acts as an intelligent hub for the house, linking together other smart appliances with a voice interface. Once set up, it listens passively at all times. When someone says the wake word—Alexa—it snaps into action. For now, those actions are limited to simple operations, like reciting your calendar events, queuing up your favorite playlist, relaying weather or sports scores and, of course, ordering household items from Amazon. But those tasks won't remain simple for long. In June, Amazon released the Alexa Skills Kit (ASK), opening the platform to dozens of third-party services, devices, and apps, including WeMo, Philips Hue, Pandora, and Wink.

For now, only a handful of the most popular apps use 3D Touch, but it's only a matter of time before it too becomes part of our everyday lexicon. From $650Apple
SUSIBA2: Rice That Fights Global Warming

SUSIBA2: Rice That Fights Global Warming

More than half the global population relies on rice as a regular part of their diet. But rice paddies have a downside for the planet too: They produce as much as 17 percent of the world’s total methane emissions. So Christer Jansson, a plant biochemist at the Pacific Northwest National Laboratory, spent the past 10 years developing SUSIBA2, a genetically modified rice plant that emits almost no methane. Splicing a single barley gene into common rice, his team found, changed the way the plant handles photosynthesis: Instead of sending carbon to the roots, to feed the bacteria that produce methane, the plant directs it toward the grain and leaves, increasing the starch level and yield. “It’s a win-win,” says Jansson. The rice performed well in field tests in China, and now scientists are studying how cultivation affects it. Jansson says there’s no telling when the rice might be commercially available, but considering how severely methane can accelerate climate change, its eventual impact could be huge.Courtesy of U.S. Department of Energy's Pacific Northwest National Laboratory
