00:01Traditional LEDs have been around for years, emitting colors like red or green.
00:06However, creating blue LEDs was a tough nut to crack due to the complexity of the process.
00:13In 2014, three Japanese researchers snagged the Nobel Prize in Physics for their work in making blue LEDs a reality.
00:21They developed a new semiconductor material called gallium nitride, which paved the way for efficient blue light emission.
00:28This breakthrough not only revolutionized the lighting industry, but also contributed to sustainable energy solutions.
00:37By combining red, green, and blue LEDs, you get white light.
00:42Alternatively, you can excite a chemical layer in a bulb with blue light to emit white light.
00:48LED lighting is more energy-efficient than other types, making it a momentous change for the 1.5 billion people
00:55without access to electricity grids.
00:58If all lights were LED, global electricity usage for lighting could drop from 20 to 4%.
01:06Some LED systems are designed to adjust the light color throughout the day to align with the body's natural rhythm,
01:13offering a more comfortable lighting experience.
01:17Scientists were aware of the concept of materials made up of single atomic layers.
01:22But no one had managed to isolate one until recently.
01:26For years, researchers had been attempting to create a single layer using advanced and costly methods.
01:33However, the breakthrough came when a group of scientists use a simple and inexpensive tool, regular sticky tape, to isolate
01:40a single sheet of graphene.
01:42In 2004, a team of scientists announced the discovery of graphene, a thin layer of carbon just one atom thick.
01:50This discovery surprised the scientific community, as it had been believed that materials like graphene would be too unstable to
01:58exist.
01:59Graphene quickly became the talk of the town, with new findings on its properties adding to the excitement.
02:05In recognition of their work, the scientists received the Nobel Prize in Physics in 2010.
02:11The idea that strictly two-dimensional arrangements of atoms would be unstable was long-held, but recent research has shown
02:19otherwise.
02:20Graphite, which we commonly find in pencils, is made up of layers of carbon atoms arranged in a hexagonal pattern.
02:27These layers are what we refer to as graphene.
02:30Interestingly, the discovery of structures like buckyballs and nanotubes hinted that carbon could indeed form stable 2D sheets.
02:39One of the most fascinating qualities of graphene is its exceptional electrical conductivity, allowing it to carry significant currents at
02:48room temperature.
02:49Its unique properties have opened a world of possibilities in electronics and material science.
02:55Researchers are also exploring graphene's potential in fields like solar energy and battery technology.
03:03Now, the idea of touchscreens on devices has been around for a while, even showing up in science fiction movies
03:10and books.
03:12However, it took a lot of time to actually develop the technology to accurately sense and respond to finger touches
03:19on screens.
03:20Many people think Steve Jobs dreamed up the touch interface, but that's not quite true.
03:26He just introduced the technology in a way that really caught people's attention.
03:31Apple engineers have put in a lot of effort to improve the technology, adding features like scrolling without the need
03:38for physical buttons.
03:39The first touchscreen device is believed to be the work of American professor Samuel Hurst in the early 1970s.
03:47He was looking for a way to automate reading information from recorder tapes, which led to the creation of the
03:53world's first touchscreen.
03:54Over the years, touchscreen technology continued to evolve, eventually leading to the development of touchscreen smartphones and tablets.
04:04In 2002, companies like HTC and Zenarch Technologies started producing devices with touchscreens, setting the stage for the popular devices
04:13we use today.
04:15These devices have found countless applications in various industries and have improved how we interact with technology.
04:22So, while Steve Jobs may not have invented the touchscreens, his contribution to making them mainstream cannot be denied.
04:30Now, for years, the concept of flying with a personal jet engine attached to your back has been a futuristic
04:36dream.
04:37However, the reality is that this dream has yet to become a mainstream reality.
04:42Despite promises of a practical jetpack hitting the market soon, there are several reasons why this technology has not taken
04:50off.
04:51First, the human body is not naturally built for flight.
04:54Without genetic modifications to create lift, individuals cannot soar like birds.
05:00This means that all the lift must come from the thrust generated by the jetpack.
05:05Next, thrust requires a significant amount of fuel, which can be expensive.
05:11Carrying more fuel for longer flights adds weight, requiring even more thrust and burning more fuel in a vicious cycle.
05:19Additionally, most jetpacks use rocket propulsion, which requires carrying both fuel and oxidizer.
05:26Jet and rocket packs are also difficult to control and can be unstable in flight.
05:31The short flight time limits the ability to reach a safe altitude for emergency situations, such as engine failure.
05:39Plus, the inefficiency of flying one person with a jetpack makes it impractical for most uses.
05:45While they may look cool, the practicality and cost-effectiveness of jetpacks have yet to be realized.
05:53The idea of using light in a precise and powerful way sounded like something straight out of a sci-fi
05:59movie until lasers were invented in the 1960s.
06:03Since then, lasers have totally changed the game in industries like medicine, fiber optics for communication, and manufacturing,
06:11where they're used with incredible precision for things like cutting and welding.
06:16Even though lasers can now come in all sorts of colors, making a white laser was a whole different story.
06:23White light is made up of a bunch of different wavelengths, unlike a single wavelength that traditional lasers produce.
06:29But instead of seeing this as a roadblock, many scientists view it as an exciting challenge.
06:35One idea for making a white laser is to combine several lasers to create a beam that looks white to
06:41us.
06:41But getting this to work without losing coherence is no easy task.
06:46Still, some researchers have succeeded in making a white laser using just one crystal,
06:52proving that there are new and creative ways to push the boundaries of optics.
06:57Back in 1903, Henry Ford's lawyer was advised against investing in Ford's automobile company.
07:04A mysterious person told him there would always be a horse and cars were just a passing fad.
07:09Well, as of 2021, almost 300 million vehicles were registered in the U.S. alone.
07:17Take that, Mr. Anonymous Advisor.
07:20Jokes aside, at the beginning of the 20th century, people indeed didn't really welcome the whole concept of cars.
07:27Americans weren't really feeling the whole cars-in-the-city thing.
07:31But as highways, suburbs, and anti-walking laws started popping up,
07:36people started to come around to the car-centric lifestyle.
07:39This shift meant less focus on walkable communities, which is kind of sad,
07:44because it affects our ability just to stroll around our neighborhoods.
07:48Now, there's a common misconception that the price of lab-grown diamonds will drastically decrease in the future.
07:56This misconception is often promoted by the mined diamond industry,
07:59which claims that lab diamond prices will eventually plummet to the level of lower-quality diamond simulants, like cubic zirconia.
08:08The reality is that high-quality lab diamonds are quite rare and difficult to produce.
08:13Growing brown or industrial-grade lab diamonds is easier and more cost-effective,
08:18while growing colorless, high-quality lab diamonds is a complex and expensive process.
08:24Similar to mined diamonds, there are two distinct categories of lab diamonds โ high-quality and low-quality.
08:31Makes sense to me.
08:33Most lab diamonds on the market fall into the low-quality category,
08:37while high-end retailers offer access to superior-quality lab diamonds that are much harder to grow.
08:43The process of growing high-quality lab diamonds is a challenging one,
08:48due to the speed limit on how fast a diamond crystal can be grown.
08:52Trying to speed up the growth process can result in diamonds with fractures, low clarity, and undesirable undertones.
09:01Shortcuts, such as adding boron during growth,
09:04can lead to low-quality lab diamonds with a blue tinge or brown color that needs to be irradiated to
09:10remove.
09:10Cutting and polishing lab-grown diamonds is also a costly and labor-intensive process,
09:16requiring the use of multi-million-dollar laser tools and highly skilled technicians.
09:22Has your trusty phone ever let you down?
09:26More times than you can count?
09:27It always seems to run out of juice at the worst possible moment.
09:31You forget to top it off, or you end up in an area with no service.
09:34And let's not forget how useless it can be in an emergency, like during a tornado when there's no signal.
09:41But fear not, there's a cool project called Mesh-tastic that uses a wireless protocol to keep you connected with
09:48your friends.
09:49It's like magic, using a radio band called LoRa for encrypted messages.
09:54It works in literally any external conditions.
09:57Plus, each device can act as a repeater to extend the range of your messages.
10:02Perfect for disaster recovery or just keeping tabs on your kids.
10:06For less than 25 bucks, you can get a starter kit to join the Mesh-tastic fun.
10:11Add a GPS module and a battery, and you've got your own private channel.
10:15No more stressing when your kids are out and about.
10:18You can instantly see where they are.
10:20And if you're feeling daring, you can even send low bit-rate audio through the airwaves.
10:26Now, I'll bet there's a bunch of things your car just can't do.
10:29Can it lean into corners? I don't think so.
10:33What about adjusting its own width to park easier?
10:36I know your answer is no, but let me show you something then.
10:39This cutie is called Trigo EV.
10:42And even though it looks like a futuristic stroller, it's actually a fully functional quadricycle you can totally drive.
10:49It was initially created for delivery and car-sharing purposes, but it turned out cooler and way more comfy than
10:55expected.
10:56If you ever find yourself driving this electric, yeah, let's call it a car, shall we, you won't need anything
11:02else but a tiny patch of land to park it.
11:05It has a maximum speed of 56 miles per hour. Not bad for such a tiny car.
11:10In cruise driving mode, it measures 58 inches wide, but a mechanism allows the front wheels to retract toward the
11:17chassis, reducing the width to 34 inches.
11:20The electric four-wheeler weighs slightly over 1,000 pounds, with a total permissible mass of around 1,600 pounds.
11:28Right, it all looks futuristic and fun, but I feel safer in good old SUVs.
11:34Ever wished you had an extra arm to help you out when your hands are full?
11:39Scientists have figured out how to control a robotic third arm using just your diaphragm muscle.
11:44It's as easy as pie, if pie is easy.
11:46This awesome discovery was made in Switzerland as part of the super-cool third arm project.
11:52They had volunteers wearing exoskeleton arms and a sensor belt to track their diaphragm movements, all while navigating a virtual
12:00world in VR.
12:01After over 150 sessions with 61 volunteers, most people found it a breeze to control three arms at once.
12:09They could even multitask, chatting and looking around while using the third arm.
12:13Now recently, a new, fully autonomous delivery service with fast food joints was launched.
12:20This means no people involved from pickup to drop-off.
12:23It's called Flytrex, and it's been delivering using drones since 2017,
12:29teaming up with big names in retail and food to bring you quick and cheap deliveries.
12:33They're currently flying high in North Carolina and Texas, with plans to expand nationwide.
12:39Their goal is to make deliveries faster and cheaper using their trusty drones.
12:43Your order could be at your door in as little as five minutes after it's ready.
12:48Now, that's speedy.
12:49Flytrex got a huge increase in customers and even FAA approval for long-range drone deliveries in 2023.
12:57Partnering with big brands like Unilever and Papa John's, they're definitely on a roll.
13:02More a pizza roll.
13:03The Monocab OWL project is all about making a super-cool monorail vehicle for getting around in rural areas sustainably.
13:11The Monocab is a clever little autonomous monorail vehicle that can balance itself on a regular rail without any extra
13:18support.
13:19Its slim design allows it to zip along single-track lines in both directions, perfect for some unique rail mobility
13:26ideas.
13:27It's like a fun service-on-demand option that's way more exciting than your usual transportation choices,
13:33especially for reviving old railway lines in rural areas.
13:37Everyone on the Monocab OWL team is stoked about shaking things up in rural mobility.
13:43Right now, there's a lack of good, eco-friendly and budget-friendly options for getting around in less populated areas.
13:50Reactivating old railway lines is a great start, but we need some fresh ideas to really make it work.
13:56That's where these small, self-driving rail vehicles come in.
13:59They bring together the best of rail travel with on-demand booking and a cool digital navigation system.
14:08Look here!
14:09Can you identify what this weird-looking object is?
14:12It's a mobile solar container with foldable solar panels for green energy on the go.
14:18Just pop out the panels, unfold them, and you're good to power up equipment and properties with green energy wherever
14:24you are.
14:25The solar container can extend up to almost 400 feet in length when fully unfolded, and has 240 solar panels.
14:33It's perfect for both on- and off-grid uses, like rescue missions and outdoor events.
14:38And it only takes about 5 hours to set up. Easy-peasy.
14:42There's even an automatic conveyor system for easy folding and unfolding of the panels.
14:47Just push a button and start harnessing solar power.
14:51SolarCont, the Austrian company that invented it, estimates this mobile solar container can power around 32 households.
14:59Virtual meetings are all the rage nowadays.
15:02Remote chats are cool, but let's be real, they're no match for face-to-face meetings.
15:07We can see each other, hear each other, but it's still pretty flat and 2D.
15:12Or, shall I say, it was flat.
15:15The thing is, HoloBox from HoloConnects is bringing holograms to life.
15:20This super cool device lets you project a life-size hologram of yourself, or anyone else, inside a funky box.
15:27Just plug it in, connect it to the internet, and voila!
15:31You've got a hologram ready to go.
15:33You can even connect multiple boxes to showcase big stuff like cars or anything else.
15:39Now, holograms are a massive game-changer for remote communication.
15:43Imagine chatting with someone and seeing them in 3D like they're right there with you.
15:48Plus, it adds a personal touch to presentations, training sessions, ads, you name it.
15:53What do you think?
15:54Does this look cool or creepy?
15:57Check out the latest creation from a rock star team of engineers at NASA Ames Research Center and KBR,
16:04a robot system that can autonomously build structures using lattice blocks.
16:09Their paper in Science Robotics explains how these robots and blocks work together to create amazing things.
16:16Designed for future lunar missions, these robots can lay down foundations for shelters before astronauts arrive.
16:22Three robots work together to carry and connect blocks with twisty edges, similar to assembling IKEA furniture.
16:29They have already built impressive structures, like a shelter made of 256 blocks in just over 4 days.
16:37Imagine what they could do on the moon!
16:41Experience the interactive pearl sculpture by breakfast.
16:45No food implied, just the name of the company.
16:47It's placed on a huge cruise ship called the Icon of the Seas.
16:51This stunning creation imitates the ocean's vibes, with rolling waves and shooting stars, each tile placed in a neat Fibonacci
16:59sequence.
17:00Using real-time data from the Caribbean, this sculpture changes constantly to match the current weather and tides, bringing the
17:07ocean to life before your eyes.
17:10Yeah, this invention won't change your life, but it's meant to nurture your soul.
17:14Have you heard about the Seattle-based startup JetTaptra?
17:17They're developing innovative vertical takeoff and landing vehicles with bladeless propulsion systems, promising a future of quiet, safe, and fast
17:27urban flight.
17:28By 2050, 70% of the population will be living in cities, leading to crowded streets.
17:34But JetTaptra's fluidic propulsion system offers a solution, using air pressure technology for silent operation.
17:41JetTaptra is also working on a high-speed VTOL for the U.S. Air Force, with plans for passenger-carrying
17:47prototypes by 2026.
17:50Well, that's exciting!
