There's this invention called "The Anti-tanic," which is basically a high-tech lifeboat designed to be unsinkable, even if it hits an iceberg. Then there's this other cool stuff, like a special suit that inflates to keep you afloat if you fall overboard, and a smart buoy that sends out an alert if it detects someone struggling in the water. These inventions are all about keeping people safe at sea, whether they're on a big cruise ship or just out for a day of fishing. They're like superheroes for sailors, making sure everyone comes home safe and sound. Credit:

00:00 Water, Earth, Air. These are the three elements that can unleash disasters.
00:07 Thankfully, the masters of all elements, aka scientists and engineers, created these seven genius inventions that might one day help save your life.
00:18 Your home insurance company will appreciate you investing in this one.
00:23 Floodworks vinyl tubes are like big, long pillows made of strong plastic that are filled with water.
00:29 Each tube is four feet long and can be used to block water from getting through doors or into garages, as well as divert it.
00:37 They're good for stopping water that's up to six inches high.
00:41 You can bend these tubes into different shapes and they will hold their new form.
00:46 They're designed with a cap on one end to fill them up with water.
00:50 The other end has a special opening that lets you connect tubes together with a clip to allow you to create a longer barrier if needed.
00:58 There's a part on the tubes called a break, which stops them from rolling away.
01:03 To keep out taller amounts of water, you can put one layer of tubes on top of another, making a triangle shape like a pyramid.
01:10 This can keep out water up to 12 inches high.
01:14 However, it's advised not to stack them any higher than that.
01:18 If you've got deeper water, you might need a different waterbending move.
01:22 I mean, flood solution.
01:25 If only Titanic had this invention on board.
01:29 In the event of a shipwreck, we know by now that old school lifeboats are too slow to launch and there aren't enough for everyone.
01:36 Life buoys, on the other hand, are too few and can only save one person each.
01:41 And life jackets are often not within easy reach when you really need them.
01:46 This is where instant relief comes in handy.
01:50 So cleverly called the Anti-Titanic, it is a lifeboat that allows multiple people to stay safe and together in the event of a shipwreck.
02:00 It has a crisscross, waffle-like pattern that acts like many life rafts, allowing a large number of people to stay afloat.
02:09 In case of an emergency, once the ship's sensors detect damage, the alarm sounds and the device gets to work right away without anyone having to do anything.
02:18 Fueled by high-pressure carbon dioxide, it fills up with gas in just two minutes.
02:23 The life mat can be 50 square meters, so there's room to save plenty of people.
02:28 And no, people don't need to literally jump ship to get on it.
02:32 The device inflates and forms a ladder against the ship's side, so everyone can climb down this ladder and onto the safety of the big air mat.
02:42 What's even more clever is that the mat has different sections.
02:46 People who need extra help, like the elderly, children, or those with disabilities, can stay out of the water and rest.
02:53 If earthbending is not one of your skills, better check this invention out.
02:58 Debris flows and shallow landslides are like super-fast rivers of mud that can carry big rocks, tree branches, or even large boulders.
03:08 They happen when too much rain or melted snow makes the ground on hillsides too wet and slippery.
03:14 Especially if there aren't any plants or trees to hold the soil together.
03:19 This can also happen when the ground gets burned in a wildfire and there's nothing left to protect it.
03:25 Debris flows usually follow the shape of the land, moving through natural paths like gullies or ditches.
03:32 If nothing stops them, they can damage roads, bridges, and houses, or even block rivers.
03:39 This is where the debris flow barriers come in handy.
03:42 They act like a big net that catches these "mud rivers" before any disastrous consequences.
03:48 Placed right in the natural paths of the debris flow, the barrier has special elements that soak up the energy from the debris flow,
03:55 slowing it down and stopping all the "stuff" from moving further.
03:59 What's also great about them is that they don't damage the environment.
04:03 One can take them down without leaving a mess and put them back up again if there's a risk of debris flows in the future.
04:10 This little box created by NASA engineers is not looking for extraterrestrial creatures or other planets.
04:17 It's a life-saving radar called Finder that's designed to find people trapped under the rubble of collapsed buildings right here on Earth.
04:26 Using a technology that is similar to what might be used for space exploration,
04:31 Finder can detect the tiny, rhythmic movements of a human heartbeat and breathing amidst chaos and destruction.
04:38 The way it works is like this.
04:41 It sends out a safe, low-energy microwave signal into the debris, which is much weaker than what your mobile phone emits.
04:48 As the signal then bounces back from the rubble, Finder listens for patterns that show someone is there, living and breathing,
04:56 even when they can't call out or may be unconscious.
05:00 The device is so sensitive that it can tell the difference between a person and an animal.
05:05 Engineers also use a unique method to pick out these signals of life from other random movements, like leaves shaking or other non-life patterns.
05:15 According to tests, it can search a small building in about 10 minutes and a much larger area in about a half an hour.
05:23 On the other hand, the next invention is designed to help save lives, not after, but during the event of an earthquake.
05:30 Earthquake-proof table is a sturdy school desk that doubles as a life-saving shelter during earthquakes.
05:37 While kids are often taught to duck and cover under their desks when the ground shakes, regular tables can become traps if they buckle or collapse.
05:45 But not this one. It's built to stand strong during quakes and keep the kids safe underneath it.
05:51 What makes it special is that it's been thought through for different ways buildings can fall apart during a quake.
05:57 This way, it ensures kids can have a safe spot no matter what and can be reached by rescue teams afterward.
06:04 It has also been put to impact tests with various types of weights and debris to confirm it can take a beating without going in.
06:13 Besides its strength, the table is light enough for two children to lift and move, as well as spacious enough to accommodate a pair of students seeking refuge.
06:22 This invention basically allows you to bend water and air at the same time.
06:28 Imagine you're out enjoying the waves or paddling on a lake, and you suddenly need a bit of help to stay afloat.
06:34 This is where Kingi, which is the world's smallest wrist flotation device, comes in.
06:39 Worn around your wrist, it's sleek and barely noticeable until you need it.
06:44 In the event of distress in the water, you can activate it by pulling a lever, which triggers the inflation of a balloon.
06:51 This balloon aids in buoyancy, easing you to the water's surface.
06:55 The device is also equipped with a whistle to draw the attention of rescuers in critical situations.
07:02 Kingi is not a single use.
07:04 Once you're back on dry land, you can deflate the balloon, fold it back inside, pop in a new CO2 cartridge, and it's ready for your next water adventure.
07:14 The last invention on the list is like a guardian angel for adventurers in snowy mountains.
07:20 When an avalanche hits, it can be a race against time.
07:23 In such an event, Safeback SBX helps you continue breathing if you get trapped under snow masses, all without the need for a mouthpiece.
07:33 This could be a game changer because, usually, if someone is trapped by an avalanche,
07:38 they might only have about 15 minutes before running out of air becomes a real problem.
07:44 But with the Safeback SBX, you can have up to 90 minutes of breathing help.
07:50 That's a lot of extra time for rescuers to get you.
07:53 It's been through a ton of tests to make sure it works in all kinds of snowy situations.
07:58 It's also designed to fit into different brands of avalanche backpacks.
08:03 Plus, it's light enough to not add extra weight to your backpack,
08:07 and tough enough to handle the rough and tumble of an avalanche and keep working.
08:13 That's it for today!
