THIS IS GENIUS. Why haven't we figured this out before? Whenever I go to Africa and South America I always make sure to pack a ridiculous amount of batteries. People always ask me for them because batteries which you purchase in country are horrible. This blending of an ancient technology with a new technology is a game changer, and as a mechanical engineer, I find it to be super exciting.
For those wondering, the units are just under $10, so the payback for a family in a developing nation should end up being about 3 months. This effectively eliminates the kerosene lighting poverty trap that millions of people fall into. I absolutely love it when engineering innovation solves an economic and environmental issue.

Turning heavy into light.
Hey, who turned on the heavy?
+BBBuilds12 Your mom.
+Caleb Limb There's that word again! Heavy! Why are things so heavy in the future, is there a problem with the Earth's gravitational pull?
+Caleb Limb Yeah, it's not turning gravity into anything, it's turning the force/effort used to lift the heavy object up off the ground into depreciated power output over time...
+LeastComicStanding So, it's just turning gravitational force into light.
back in the 2019 they thought gravity was infinite... here we are now.. floating around. It all started with this lamp
Daniel De Lauretis this commet is golden 😂
Daniel De Lauretis They HAD to monopolised everything including gravity
Lmao
I'd say it does not work with gravity, It works by the force and energy we put in the weights when we lif them up and hook them.
@@sajjadjafari2612 yes, that's where the energy comes from. You're transforming your calories into gravitational potential energy by lifting the weights up, which then becomes kinetic energy as the weight falls, driving a motor producing electrical energy, that then runs through an LED to produce light. Pretty darn neat.
Brilliant!
The most impressive part is subtle. The LEDs are shunt voltage limiters, so at a certain point they want to draw excessive current. Start to approach that higher current and the extra load makes the motor/generator harder to turn, and that is like pinching the last high speed gear - it wants to stop. A super simple electo-mechanical governor. Love it.
but I imagine there is a heavy enough gravity load that could be applied that would blast through the resistance of the motor, right?
@@vincent21212 sort off.. the motor (generator really) wants to stop because the high current makes it very hard to turn, but if it stops turning, it produces no current and if it produces no current, the led would not be a load and the generator would be free to turn, so it automatically finds its "sweet spot" for a particular LED load.
If the led was removed it would fall as fast as its mechanical resistance would allow.
If the led was shorted the fall of the gravity load would be slowest.
In every case, the motor always turns.
Very Cool design.
I hope some philanthropist looking for a tax write off starts sending them out to where they are most needed.
pfff I was just gonna say that ...;)
Physics is cool! The only weak link in that system is the belt. I made my living changing belts like that. They turn into chewing gum in a few years.
Thanks for this explanation but I can't quite wrap my head around how the voltage limit of an LED makes the motor turn more slowly?
I do some very very basic (electronic) prototyping and if I don't add a resistor, the LED will draw power until it burns out.
Do you have any sources I can use to learn how your explanation works?
I love how their faces lit up for a split second when you said "that's genius"
Turning compliments into light!
They didn't invent the gravity light: it was made the same way for third world issues, the same way (with a Brick hanging and a normal bulb, running 1hour before reset). The third world 8nvention was meant to be sold for 15 Dollars. Chheeers

Stop wasting gravity.
+Rodrigo Appendino ha ha ha. Just tell anyone you don't like to go stand in a gravity powered generator so at least their existence will produce something... :P
lmao
this is my favorite comment in a long while, thanks :)
Gravity
2015: 9,8 m/s²
2115: 5,6 m/s²
Exactly, children in Africa could've eaten that gravity.
Things like this restore my faith in humanity, but then I turn on the news and it quickly goes away.
+Awaken the Evil That's why I quit watching the news. Ignore it and it effectively doesn't exist. Nothing they ever talk about on the news ACTUALLY matters, anyway.
+Awaken the Evil The solution is simple: don't turn on the news.
+Awaken the Evil Don't watch the news (Y)
Just follow some news outlets, not fox news and the likes, who just put out what people want to hear, why do you think they have hot woman reporting all the time lol IF you follow them on Facebook or wherever you can click on the article if you want to read it
+Awaken the Evil There is actually less violence than in past times.
We have being turning gravity into light for years in hydro plants...
@yeah I'm John Assal Well Solar Fusion only exists because gravity exists so...
@yeah I'm John Assal Haha
Even so, little devices like this make for a nice, practical invention. Maybe with a big enough gravity load (weight) we could create a nice general-purpose generator.
@@ORagnar i dont think its scaleability is practical.
@@Ian-ie3hy Maybe it can work as a light house of sorts...
_Exactly, precisely, Exactly_
Precisely. ;)
Absolutely 🤣
Indeed
the light is not exactly powered by gravity. It is powered by your muscle when you raise the weight. The falling weight is just a store of energy that was created by the person
+ambrous shut uuuuuuup
+ambrous Well TECHNICALLY muscles are made of star stuff, and the sun is a star, so really it's solar powered. :)
+ambrous but if there wasn't any gravity it wouldn't fall and it wouldn't create any power to power the light so gravity wins (gravity falls to be more accurate )
+ambrous thanks i was actually a bit confused
yes it is the potential energy
Jim had me at 3:22 with the way he held his mug :D
+doombringer6s I'm convinced he's a modern day wizard.
+SmarterEveryDay And wizards like him become harder and harder to come by these days. The more i see your videos, the more make me want to delve into science more , but im so used to my artistic vein that i cant get over their differences. Please advise xD
+SmarterEveryDay He's what I imagine young Sirius Black to look like.
+doombringer6s lol didnt notice that
+doombringer6s Crawlspace habits? I guess with the layout of the shop, he probably got that habit after bumping in others a few times, spilling the content of his mug everywhere. By walking with his mug behind his back, he increases the time he has before bumping in someone as well as reduce the movement of the mug by the factor of energy transfer not reaching fully down his arms, reducing spillage. (Sorry if that doesn't make much sense, I'm not sure how to word it correctly for it to actually make sense.)
You thought it was gravity, but it was me, muscle power!
Yeah I was thinking about that
Each light session lasts 20 minutes? That's pretty sweet.
I'm smarter than yesterday.
"older and wiser"
Older yet none the wiser in my case.... ;-;
+Red Sniper same with most people, don't worry
And one day closer to dying ;-;
Future FG Gaming Yep, you are wiser.
Great video! But I feel like you failed to explain why/how an LED light can prevent the generator from moving regardless of how much weight is applied. That seems like the most fundamental part of this invention!
+karmakazi219 There's a video that explains that which will be uploaded to the shell channel shortly
+SmarterEveryDay The Shell Oil channel? Interesting. Thank you!
In short: A LED has a sufficient resistance so the motor doesnt get shorted. As soon as the voltage of the motor gets too high (happens when it goes faster), the LED loses resistance and is therefore getting closer to a short.
Now, you have to know that a generator that is shorted will stop immediatly. in this case, it will just be like braking a car. it limits the speed at which it can go.
You're not explaining how or why a generator that is shorted 'will stop immediately' therefore I'm no closer to understanding the answer to the question than before you made that reply.
*****
In short, it works like a watermill: If you hang something up to it, as in an actual load, it spins slower. Now, a short circuit is the equivalent of trying to power a huge city from a small little river that is hardly half a foot deep. It simply will never spin.
To explain how the generator works:
Electricity is generated by a magnetic field that is spinning around copper coils.
The magnetic field that the copper itself generates (which increases the higher the current is you pull from it) counteracts the spinning motion. So, a short circuit (which means maximum current) will simply stop the generator.
The LED is not a short circuit though, so it will simply counteract its motion just enough for the LED.
Now that is freak'n genius! The secret societies are thinking, "Now, how do we monetize gravity? Moo ha ha haaaa....!" ;-)
At 70 bucks a pop they already have...
*I'm so poor that I don't have access to gravity.*
Work as we do and you can afford gravity
You must be in outer space, or if its a play with words, not have a conscience!
Shut up Space Dweller, go to Mars for cheap gravity since you probably can't afford high gravity here.
@@Ganesha900 I would accept the latter.
@@wazza33racer That is not the answer sir. Create your own conscience is the solution. Good luck integrating with it.
It's amazing how simple this is, yet only just been developed. Got to love engineering!
+TheRecreationProject it is not that simple, these gears needed some serious calculations and the manufacturing process might be expensive so you need millions of customers to make it affordable taking into account the main objective is to provide underdeveloped countries like Africa with this product.
+Luis Fernando They didn't need serious calculation. They required the same level of calculation that you would perform in any base level physics course at a university. The process mimics that of old grandfather clocks. Would it take time to perform the calculations, yes. Are the calculations difficult or highly advanced, not as much.
+TheRecreationProject I know right? It seems like this would have been low hanging fruit.. something we did ages ago!
+SmarterEveryDay Why hasn't it then? The only thing I can think of is that LEDs are relatively new and other light bulbs wouldn't have been very practical.
+Steve Balsamo Because most people have access to batteries and the electrical grid. Batteries are far more convenient (and mobile!), and the electrical grid is far more convenient, cheaper, and powerful.
Connect a bunch of these to a single weight that travels down a deep well and you can light up an entire small village for a couple of hours.
+Neumah Or a single bigger generator?
+Neumah Or build 1 wind turbine.
+Deline Needs wind, gravity is more consistent.
+attrem Also needs a large space. This is tiny in comparison.
+Neumah Muscle isn't a great way to make electricity beyond a dim one-room light.
Talking about Children have to burn Fuel to have light for homework.
Video is powered by Shell.
lmao
Lmfao
Which probably destroyed their country
What are the plastic gears made from? What is the plastic casing made from?
Alternative energy doesn't hurt fossil fuel companies. They are diversifying their products since the fossil fuel they're relying on is not permanent anyway. In fact, it give them more initiative if they want create context, the "switching" point on the market when their stored resources are running out.
i am sure you have helped a lot more poor people than this light made with Shell's money will ever help. /s
You mean I can’t use this in space? Please come up with Zero Gravity light, please. Thanks.
You're asking too much...
Didnt Tesla do that already?
Stored Solar power
Fun Fact, there are people developing human-body-heat powered torchlights
You could probably use a spring or elastic band with enough gears, but you'd still have to reset it often.
turning your cap around to reveal the headlamp cracked me up
it was so slick and so dorky at the same time
"Click here to see how Shell used to drill arctic for oil and now tries to look good saying they support renewable energy"
*says the consumer.
i like bathing in oil
+Smadonno "...Whilst still drilling for oil in the arctic".
+Smadonno Shell and any other company should be given the opportunity to explore new and more ethical paths, like this gravity light. They shouldn't be dismissed as irredeemable just because they are in oil right now.
+Tristan Patterson actually you can live on 100% renewable... and its not that much more expensive, a home can easily run on renewable... in fact my electricity and gas only come from renewable sources.
Hi Destin, my 5yo son would like to say; "I kinda like the light because I want to see, and I like the video."
I play videos for my son at bedtime and I watch to see which of them capture his attention spark his imagination. Smarter every day is his favorite, he has been watching your videos for about a year now with no signs of loosing interest. Thank you Destin for opening his mind to bigger ideas.
Technically, you aren't powering by gravity, you are powering by food since the energy input comes from lifting the weight.
Gas power comes from solar energy stored by plants and microorganism that became petroleum. So, petrol cars are solar powered.
Technically, all energy originated at the creation of the universe. So this is all just stealing God energy: thieves!
@@sargondp69 you still believe in God ? If yes which one
@@sarojrani8181 who say there are many there is only one.

This would be a neat item to even charge your devices.
Which is also a challenge to do at night in developing nations.
+SmarterEveryDay or any airport.
+KiddsockTV Seems impractical. Gravity isn't really a good way to store energy, since it just takes so much stuff so high up to store any real amount of energy.
To put this in perspective, their 12.5 kg/27.5 lb weight would need to be 300m/1000 ft in the air to have enough energy to charge a current gen iphone, and that's assuming perfect efficiency.
Really, this solution is great to provide some basic lighting, which requires incredibly small amounts of power with LEDs, and there are a few other applications where this would be great, but for charging something like your phone and so on? No.
+seigeengine
*SO WHAT'S THE PROBLEM !?*
When the weight eventually reaches the ground - you just hoist the weight back up again - unless you're super lazy - people in 3rd world countries don't have time to be lazy - quit being so negative.
VL VIDEOS The problem is if you used this set up, you'd need to haul the bag up a couple hundred times to charge your cellphone.
Also, point here... it would be more efficient and more compact to drive the system yourself rather than going through the intermediary of storing energy against gravity, and then using that.
I like Jim.
lol i thought the same thing while i was scrolling down here
I like trains
+Mark Ifi So do I
+Mark Ifi Exactly
He's even cooler in person.
I foresee a gravity shortage by 2025! This is great, I have spent time in countries where this would not only be life changing but life saving!
Reduced gravity will cause the seas to rise and polar bears to migrate into cities.
yes but we will definitely start flying on earth. Its gonna be a great achievement.
Wow, what a simple idea and not converted for use by masses. Good on you and keep up the good work.
This is actually along the lines of what people are proposing as a solution to storing solar power on mass.
Because lithium batteries can only hold so energy and they lose energy too fast for large reservoirs. Using solar power to lift an object while its getting energy and letting the object fall when there is no more sun gives you the ability to store energy theoretically until gravity stops working or something physically brakes.
The trick is translating solar energy into lifting energy efficiently.
Sean Peery Actually gravity is already used as storage as pumped hydro-power
Sean Peery oh and their efficiency is around 70-80%
matucha123 Thank you.
This is not practical. A small solar farm with an output of 10 megawatt will need to store 180 billion joules (10 hour day, half of the energy is stored for the night). You will need to lift an anchor that weighs 1 billion ton to 180 meters. If iron is used, it will cost around $88 billion not accounting for the labor, structure, and lifting mechanism.
I think you've made a mistake here: 1 J is 1 Nm. 1 N is approximately the weight of 0.1 kg under Earth gravity. So you don't have to lift 1 billion tons 180 m but only 1 billion times 0.1 kg or 100,000 tons. The hydropower plant near the town where I grew up has a head of more than 800 meters, so to store 180GJ you would have to pump up less than 22500 m³ of water. Doesn't sound that bad. (And in fact using reservoir power stations to store excess energy has been done since at least the 1960s.)
it's a human powered light... that uses gravity and potential energy as a medium to store the energy, like a windup toy that uses a spring instead.
Grip Limit exactly. A humen still has to hoist the weight in position. That uses humen energy.
Still, technically it's the gravity that moves/pull the weight. We usually call a windup toys a "spring powered" toy, just like this a "gravity powered" lamp.
Immanuel Herman sure those examples are how we define the way we store the energy, but we (humans) still put the energy into it. unlike your cell phone that you plug into an external power source, or buying batteries for a flashlight.
And humans are food-powered. Which is sun-powered. So I guess it's a fusion-powered light ;-)
Diego C. you are correct. almost all energy on the surface of this planet comes from that big ball of plasma in the sky.
I bought one for my son for his birthday a while back. He loves it better than any other gift I have ever bought him. We regularly feed treats to our cats that come in plastic canisters. Using the canisters, we filled them with pea gravel we got at Lowes. We don't have to worry about spilling the gravel or it wearing through the bag. Finally, something that really works. I wish this guy would reinvent the toilet flushing kits. It would save billions of gallons of water a year.
That's some awesome engineering right there, and reality at the already low cost i could see everyday consumers covering the cost to tool up for mass production to provide them basically free to people in need while the market covers rest.
These sort of Ideas is why we should have more Co-Ops so that it can be shared around instead of having to do it all yourself.
This is very clever, but can you turn light into gravity?
All energy exerts a gravitational force so yes
pineapplepenumbra yes. Cody's Lab does an experiment where he does just that.
Billy Dengel
Thanks, I'll look it up.
solar light heat up water -> vapor go up and fall
Believe it or not, yes. If you were to take a powerful enough array of converging laser beams focusing on a single point, they will form a black hole.
I don't have access to gravity D:
Egyptians invented geometry, medicine, the clock and much much more.
invented is the wrong word. they knew something about it.
things have to be reinvented all the time.
Angel Mascareñas perhaps 'brain' would be the right term?

😂😂😂😂😂😂

No one has attempted to convert gravity into light..
The sun: *Im a joke to you?*
This video just made a bunch of people dumber (every day) by making them think gravity was some form of energy which could be harvested.
+Joshua Pearce you can't be serious.
i thought they teached potential energy in like pre-school.
hydroelectric plants work on the same principle. store potential energy and harvest it slowly.
+Joshua Pearce Yeah, thanks Shell!
***** Yes, potential energy is what's at work here. Gravity is not consumed during this process. It would be almost just as wrong to say it's turning bags of sand (or whatever the weights are) into light.
And the title is "Turning gravity into light", not "A machine that produces light as a result of gravity."
+Joshua Pearce Your comment should be titled "Turning a douchebag into a comment."
DragonTech Assuming I'm the douchebag, I'm still here, so I was not turned into a comment.
Wait, the generator is the thing that prevents the bag from falling down so fast? The LED won't let the generator turn faster, I get that, but HOW?
+CheeseWithMold Yeah, I wish they'd explain that in more detail.
+CheeseWithMold It's magic, don't question it
+CheeseWithMold The LED sends a back current that causes the motor to short out and lock magnetically until the current drops again, at least I think so. So really the weight is jittering really really fast as the motor locks and unlocks
+CheeseWithMold I'm confused by this too. If you were to switch off the light, the bag would stop dropping? I'd love if you could explain this, Destin.
+CheeseWithMold +jatzy
From the resistance of the LED, voltage=current*resistance.
Since LED's only run at a certain voltage, the resistance and therefore the current of the LED change to achieve that voltage. Think of it as a funnel, if you pour sand into the funnel it will slowly drain out at a constant speed. decrease the size of the hole at the bottom (increase the resistance) the sand will flow through slower (current). Pretty much if the resistance increases, the current decreases causing the voltage to be steady state. So to keep the voltage constant, the current and resistance is changing (internal property of the led) depending on how much mass is in the bag. hope that helps explain it to you! if not feel free to ask away.
pepoles in falling lift: why its falling?

Worth waiting
+Blu3Emperor I love it. It's like christmas present in advance! :D
+santiago Marroquin also the shots of awe uploaded a new video
Just watched "the engineer guy" literally before this video and they both talk about gears... I was mind blown!
Thanks for posting this! I contributed to Gravity Light's Indiegogo campaign early on, got myself a unit and paid for one to go to someone who needed one in Africa. Mine's in my garage, lighting a dim corner. It's fascinating to see how it works!
I absolutely love this! This is a beautiful feat of engineering. Not only does this eliminate the use of harmful resources, it can be used anywhere, at any point in time by any person on earth. This is such a clever design, it is blowing my mind how simplistic it is. Thank you so much for sharing this.
There are so many great technologies that can make the world run efficiently on minimal power, but when we talk about climate change it always shifts to mega projects instead of every house having their own systems. If someone suggested we power our lights using gravity, planners would design a gigantic skyscraper-sized version to power thousands of homes at a cost and timeline that doesn't make any sense compared to building things like this into all homes and buildings. Why don't I have an exercise bike that is raising a heavy weight to the top of my house that I can use for powering the lights? Even a small windmill with proper gearing could do all the heavy lifting for those who don't want to exercise. This is a simple way of storing renewable energy, e.g. when you have wind/sun it raises the weights and generates potential energy for when the wind stop / sun goes down.
Actually, the eco-terrorists would file suit to stop the production because some small amount of petroleum is consumed in the materials and processes. Don't you know that oil is pure evil? Oil becomes the daemon Satan in their religion of environmentalism.
We should all do it but in many countrys they now taxe you or make you pay to use the sun and if you are a good nieghborg and share for free they put you in jail...
Humm some big corporations are running this earth

Makes no sense.
New ? Its 800years old ! What's new is the patent they put on it !
BRILLIANT! I still don't understand how the LED prevents it from spinning faster, why wouldn't the weight just fall faster and over volt the LED?
Agreed. Just at the most interesting bit (as a student of physics) - the mechanism for the linear decrease in GPE - his explanation is "Once the generator turns up to a certain speed and that voltage limit is reached, the LED won't let it turn any faster." Other than the circuitry having a threshold on V_emf, that is no explanation whatsoever!! *How* does the LED not let it turn faster?! That's the crux of the matter. Just stating it happens doesn't explain it, Mr +SmarterEveryDay. As such, I would very much like to see a supplementary video explaining this key (missing) explanatory step. Thank you for reading this (if you did). All the best.
PS This is an amazingly simple concept. Why has no one done it before?? As the potential energy comes from lifting an object (i.e. GPE), I'm thinking about the applications to a gym - storing electrical energy that can be used for any number of appliances one could connect to it.
((Proof of concept: Have several GravityLights in a row, lift many objects and have a larger amount of light! But then imagine creating a device where one can lift ONE object several times to store that same amount of total GPE, which can be used for whatever purpose and when the user chooses.
I also watched your video on the ARED, so maybe those guys would have some idea how to go about it.))
Electrical resistance I would assume.
bossmanham
Yeah it makes sense to say it, but when you ask yourself why it wouldn't just over volt the LED I can't seem to see any reason why it wouldn't. For instance if I had a hand crank generator hooked up to a tiny light bulb, why would it be impossible to just crank it faster until the bulb burned out?
95TurboSol Think of it like water going through a hose. The certain electrical connection, in this case the LED, can only fit so many electrons through at once. Just like a hose can only fit so many water molecules through at once.
Not 100% physically accurate, but pretty close.
bossmanham
In theory it sounds right, however it's definitely not physically impossible to fit so many electrons through something that it just melts the medium that it's flowing through because of heat. For instance, if you took a tiny string and flung it up to a high voltage power line, it would kill you even though the string is tiny, and back to the LED case, I know for sure it's possible to send enough power through an LED to burn it out, so why wouldn't it do that instead?
My favorite gravity based invention that ive seen recently is the simple rail cars they use excess renewable energy to power the car up a hill. Then when they have low energy times, Cloudy, no wind etc. They set the rail cars off down the hill and use the break system to generate electricity. Kinetic batteries. So simple but brilliant.
Give me a minute to assess the "gravity" of this situation... This is what we've all been "weighting" for.... I have seen the light..🤔🤯😅😂🤣
You say gravity.. fair enough.
I say it is a inequationated theory on a yet unexplained downward force.
Nice of you to weigh in on the topic, WC.

Just like the first case, they thought there were a satans inside the clock that automatically tolling for its every hour.....
Just reminding this history, so then we'll know who is the inventor and where the technology using gravity energy's came from....
@@louismargareth1960 Do you have a reference to this story?
@@jeanbaptiste3470 go to the library and look at the history of habsburg dynasty....
Charlemagne, the king of frank, was considered to be the king, he was the first guy who define united Europe after the fall of Rome, in the 4th century AD
And He ruled from 768 to 814 AD Pope Leo III, bestowed himself as the Augustus Imperator in Rome in 800 AD
That was the caliph harun arrasyid era....
China found gravity buried in the Australian outback when China took over ownership of Australia.The traditional owners of Australia are trying to get gravity back as they think it's an ancient spirit from the dreamtime...
It's been a long time since I've enjoyed a commercial so much, thank you!
+SmarterEveryDay can you make a video explaining how the electrical energy of the LED limits the mechanical energy created by the gears and weight. That blows my minds and completely don't see how that works.
+Tim Fevens I also want this. Does the led have a current limiting resistor? or is the generator not able to produce too much current because of mechanical resistance?
+kwanarchive I know that much but my problem is Why? I don't understand why/how an LED emitting light slows down physical matter.
+Tim Fevens I have the same question, too. LEDs do consume a fixed amount of voltage, but they usually have current-limiting resistors, which will consume as much voltage as you throw at them. (Wires are just low value resistors as well.) Without them, more voltage will increase the current , heating the wire and/or blowing the LED. But either way, I really don't see how the electrical characteristics slow the physical movement of the weight. Are you sure it doesn't just fall at a slow rate because of the friction in the gearing? What happens if you replace the led with just a resistor? Is Destin saying the weight would fall more quickly?
+Tim Fevens As an EE student, my best guess is that either the dc motor they are using has a speed limiter based on the output voltage (i.e. a system that won't let the motor over volt) or there is additional circuitry involved in that process. I don't actually have that much experience with motors atm, but the thing about the LED, and diodes in general, is that they have their set voltage limit that is used for many different applications. Look up zener diodes for example, where the breakdown voltage is specified by design. Hope I got close and was at least a little helpful!
+Chris Godley I have another guess.
I think, this is pretty simple to build. All you need is a zener diode (controls the voltage the flowing energy) and an electric generator.
The generator can act like a motor, so it slows down when its energy is not used. There's the gravity on one side and the electricity powering (yes, powering) the generator on the other side.
Better explained by an electric motor: The faster a motor runs, the more electricity it will produce (yes, produce). A generator on the other hand, will slow down if it doesn't power anything and the electricity/electrons search(es) the easiest path on their way.
And this is used in this contraption. I am pretty sure that they do everything to control the exact voltage of the diode as a slight increase of the voltage causes an immensive rise of the current. And this would cause a lot of lost energy as well as a decreased lifetime.
I don't know what it is, but you and Emily (The Brain Scoop *****) share the same wonder/surprise/admiration for Science/Knowledge. Which I find very amusing! :) Well, after all I guess I knew it!
Next time, stop by in Brazil ;)
+PratoFundo Exactly, most of our country still have problems with basic needs like light, water and food. We need more people like Destin
Brazilian here too :)
oh, there's a whole lot of good science channels on TH-cam. check out veritasium, for example
+Noam Tashma YES. The Brainscoop. Also, if you go to Emily's video "Where My Ladies At?", she lists several STEM educators on TH-cam in the description.
+PratoFundo Isnt Brazil a very dangerous place in terms of violence?
This should have 1.8 billion likes. My mind is blown by such a seemingly simple solution!
Hi Destin,i m just want to say you are a great human being that this planet earth need more like you.I m not much educated but is people like you that inspire me to move on and see the world differently,thanks
At first, title felt a bit clickbaity, but wow...
This guy always presents very interesting but offbeat subjects.
Tom Bradford - You’re right. It seems that as soon as one TH-camr covers a subject, the rest jump on board. Destin is blazing his own trail.
Destin, make more videos like this one. Truly amazing!
Everyone wastes energy on oil and gas companies instead of helping everyone find a solution for the future. This video is so valuable
Great video, right. A few supposed platitudes: It is NOT necessary to FIND a solution. Everyone can see and feel this solution every day - sun and wind (energy storage and power lines are not witchcraft either). What one should do has been known for decades.
Laziness and fear of change prevent the urgently needed implementation (not to mention lobbyism, greed, idiots denying anthropogenic climate change etc.).
the ting go skraaaa... 2:48
This idea doesn't need the hard shell, it shells itself. Sorry, couldn't resist.
LOL
Who would have thought Shell would pedal an invention that used renewable energy in the place of burning a filthy hazardous fossil fuel. The sweet delicious irony.
2:48 Haha I imagine the caretaker of the clock fuming up because of Destin’s ”rude” remark and chasing him out of the church. And Destin is like ”Okay! Let’s finish this from home!”
"I'm about to make light in the rainforest with nothing but gravity."
:Pulls out of a box an apparatus of plastic, glass, and metal filaments connected to a plastic and fabric strap and an element that moves downward when you place the apparatus up high due to gravity:
"See? I made light using NOTHING but gravity:
Oh, okay Destin. ;D
"Nothing" but gravity AND the human force to pull, those 20 killos of weight, out in a while.
It's just a small generator and every generator needs a source of energy.
This generator uses human force combined with the gravity force.
It's not ONLY the gravity force.
@@nevermind-wp3bf
Exactly, it started with the expenditure of kinetic human calories. And that began with the input of food into the system. No food, no human caloric expenditure, no light.
@@tedl7538 👍
true, because gravity is actually not energy
Hahahaha nothing is free for the slaves
You can grow a apple but you’ll have to invest $500 in pesticides they invent to kill the parasites they geoenginered and in the water you have to pay them to use to keep tree alive and then oops no apples grow anyways
Kids in Africa could have eaten that gravity!!
Well the potential energy does come from the food they eat.
What food?

Buying GravityLight online, duh
/s
Burning. (too soon? ;) )
that is awesome and you taught me something that I havnt learned in my engineering class
Wouldn’t it be better if it just recharged batteries so then you could power lights or other things at the same time instead of one light that needs to be constantly reset.
Watch from 06:41… they talk something about using a connector to redirect the power to another appliance.
Sreenikethan I. Thanks for pointing that out. I guess I wasn’t paying attention. 👍
Replacing oil with something even older, gravity, was the real genius of this.
could you have a large scale version of this power a house? use a car jack-like tool to lift a very large weight high up, and reset it every morning as part of your chores?
excuse my possible ignorance.
good idea
and connect it through a gearbox to i dont know may be your treadmill. so that 2 times exercising(morning and evening) may full up all the weights and power the lights for the nex day.
Good idea, if it was on a large scale, the generator must power a battery to power a thing to re lift the weights thought, that is the only challenge.
Sounds like the clock.
I can imagine this being applied for a giant battery.
I wonder if the energy generated can be used to lift the weight back up via a motor or something, and still manage to produce more than it wastes :O
it cant
no perpetual motion, my friend
Technically it's just harnessing your body's energy; the work done in lifting the sac results in the gravitational potential energy which powers the lamp.
So in some ways it's just like a hand-crank lamp, except you do all the work required in a matter of seconds by lifting something heavy. 😛
Plus there is no battery
As someone from Salisbury I did not expect my sleepy little city to pop up the very first day I'm learning about Smarter Every Day! Super cool
Now those guys who think gravity is just a THEORY, as they say LOL. ..
But outta jokes, THIS is really impressive and yet so simple
You guys are the ones that really make humanity thrive, they clearly haven't done this just for the money, but for the pleasure of Imagine, inventing and helping
I wish you all the best
Still can't believe I missed you when you were in my home town (Salisbury)! :(
I wonder how easy it is to replace the belt? As rubber belts get old, the rubber cracks and they break.
+freesk8 Awesome product! I hope they sell millions.
+freesk8 I'm sure the bearing will break faster due to the high stress it has to withstand. Also, the plastic won't last for decades. After 5-10 years the device will be broken, but it shouldn't be too expensive to build.
+freesk8 Good question; fortunately in several developing countries in South America and Africa they have acres of rubber trees that they sell to developed countries. So really all they have to do is continue to do what their doing but keep a little more of it for their little light belts.
+freesk8 third world country have well developed repair shops that can fix most simple things, it did not look that complicated
*****
have you been in a third world country, there is a loooooooooot of rubber and plastic(it is cheap). their is no organized way to get rid of the stuff
This is Amazing! Great job thinking outside the box GravityLight! You just helped persons save goods or money on fuel costs, helped preserve the health of their lungs, and possibly their eyes as well.. and... helped a family with getting homework/sewing/other housework things needing done after sundown! Proud of you guys!
Literally tons of ways of doing things, but i never thought about gravity. Dam!
was that suposed to be a pun
This makes me think of 2 Peter 1:19 "...whereunto ye do well that ye take heed, as unto a light that shineth in a dark place, until the day dawn..."
Yes!
neither the clock or the light is powered by gravity. they are both powered by human beings doing work by lifting weight.
No, the direct work is done by gravitational pull where potential energy is converted into kenetic then into electricity. otherwise by your logic the it is powered by the sun.
And you're BOTH correct. Human work is put into lifting a mass to a height where it obtains potential energy. The system of which it is part is then initiated and the human input of potential energy is then used as kinetic energy because the mass is attracted to the Earth due to gravity. It's all about energy. Calling it a 'gravity' powered system is a misnomer, although gravity induces the potential energy.
[And as a side note: Gravity is present in all energy, not being a property of only matter. If there is energy, there is gravity. The more energy within a conformation, the more gravity. I don't know why this concept is hard to grasp except for the fact that we don't have instruments capable of measuring the gravity of an EM wave/photon. But we know this is the case because EM radiation is attracted to black holes.]
Nakruf SteelCore so, no people needed? just gravity?
Eric Cameron Dummy ;:D , What i am saying is, a system where a human is part of the system does not mean the system is soley based on that. We could have some machie doing the liftwork i.e giving it potential energy but then we don't say the energy is directly converted from mechanical to light. There are other procesies that are in place where energy loss becomes greater.
And human beings are converting the chemical energy from foods to the kinetic energy of pulling the weights up. Foods get chemical energy from solar energy. So, you can say, it's solar energy that's running the clock and powering the light.
Wow, what an amazing inve tion.. thank you for sharing this with us.. this is why i love watching your videos, i learn something new every time from em
I got how it works as soon you let the weight go down, but I realized that those guys are so awesome to think on that... It's brilliant
"...and we will see if we can come up with any bright ideas". He said it and turned on the light.
Guys, he made a pun.
Lets go to africa and sell gravity so they can use these lamps
Sure they would love to buy it from Shell in the delta of Niger river. Shell has a lot of friends there... and a little spill of oil.
The thing is to have open and free blueprints of the device and make it from recycled materials. That's the way you do it for everyone.
I'll wait to see how this is not a image washing campaign.
Short: It's a good idea, but evil corporation funding. Not much hope
This stuff is so costly that with that money, those Africans can eat for a month
Ah, capitalism.
GRYPHON SCHNITZEL o THEY CAN'T PRICE HRAVITY DO THEY WON'T WANNA TAKE IT TO AFRICA DAMM GOVERMENT 😢
TheBlankProject do you mean an infinitely low demand at any given price which isn't 0?
This is Insanely Genius...
Thank you so much for this...
I loved it...
It's a really good idea ok 4 years old now but still it was a really good idea, the only problem I envisage is over time the rubber band will deteriorate, ok it would take years, so you would get your monies worth out of the device but still if you kept it for emergencies you could to use it and find the rubber band had deteriorated in which case you would then have no light.
That's the problem with having things that use rubber bands as some kind of drive, the band deteriorates over time, stretches crumbles or what ever then it's useless.
But it's a really good idea.
@flitsies Great point. I have a 400 cd wurlitzer-like player that no longer functions because of a rubber tube around two pullies. Stupid little part that probably costs 5 cents. I haven't figured out yet how to fix it. It got old and stretched.
the co founder of gravity light is similiar to the young professor x in x-men
it's just my oppinion
Or Loki
was searching if someone thought the same XD
dam. I would hate to be in space with that.
Zadott Erazo you could pull it down
to much effort
bungee cord
Easy, centrifugal force!
I mean, it's not actually powered by gravity, it just uses gravity to apply a constant force. You put the energy in when you lift the weight, and you have to reset it every 20 or so minutes. Same technology that grandfather clocks use, except you only have to reset a grandfather clock every few weeks or so.
This was an awsome one i love this gravity light a great emergency light for anyone anywhere. Thank you.
Shell has a long history of evil. If they do good, it's token to serve evil.
You should know better, Destin.
Job 29:3? ;) (oh, but Deuteronomy 25:13 is so close!)
+Nick Martin-Smith Oh that's good!
+Nick Martin-Smith I dont get it :/
John 8:12 comes to mind :)
Haha! Nice!
+eelektro2 his outro panel usually has bible reference to look up that matches content of video
I must have watched 20 different attempts at this very idea!! ,They were all trying to GO Bigger,like power a whole house,,& falling short,,but these guys conquared the secret!!!! Go small!!! ,,, Kudos!!
I bought 2!! They are quite rugged and perform really well. Surprisingly heavy and built to last which is not projected in the video.
That's a simple way to put it, but the light is really powered just by the person that puts the weights there.
It's just converting potential energy to kinetic energy slowly
_Ep = mgh_
That is true but I believe that this is much less exhausting than having to turn a f*ing crank for 1 hour.
but what is the person powered by? food that ultimately derives all its energy from photosynthesis? it's all solar energy when you think about it. hydro plants are powered by rivers fed by rain that is boiled out of the oceans by solar energy. even fossil fuels are derived from decomposed plant matter that stored millions of years of solar energy through photosynthesis. but what is the sun powered by? fusion that was ignited by... gravity. *cross-eyed*
So, you're saying, that if a person replaced the original bag with an open, waterproof bag were used in a rain storm, the person is still powering it because the person made made available the possibility of weight being in the bag? Well, people INVENTED the damned thing.... Ergo, according to you, all man made things are powered solely by people? Okay. Your mom and dad made you. and that's the ACTUAL source of you life-sustaining energy. Well, then what happens when you eat? you eat the food. But someone else put it on the shelf.A different person than that took it off of the truck. The person before that drove it there. someone else put it on the truck. Yet more people prepared it to be shipped. How many people did it take to grow it, including the people that raised the food. What about the ones hat provided the food for your food? Most foods have existed in some state before we were ever here. So were the basic materials for the Gravity Light and EVERYTHING ELSE, EVER! But, no... You go ahead and take credit for the the work that not-you will be doing with this if you get, or have one.
Zer0Mem0ry
I figured someone said something already... but you are correct. Gravity is just a force, not a source of energy. In this case it’s a way of storing energy. It’s analogous to saying combustion is a source of energy when specifically the fuel is the source of energy. Anyone reading this like rockets? Lol random I know but give a thumbs up if you do!
Zer0Mem0ry , this is so simple concept that we used to learn in our science class in schools. But shame that nobody got that idea before.
Now you only have to get those lamps to africa
+dxxPacmanxxb Turns out they thought of that and set up local production. Seems they'll actually be an export. Check out the website.
***** i like that
Call of duty care package... Stuffed to the brim with these things.
after the you get a 4 kills streak whilst fighting in the civilwar
Not only a brighter, but a safer place. Ingenious idea, to make a nice, bright light anywhere.
Same concept as a grandfather clock
