Our educational programs are seriously failing to teach fundamental engineering.
Agreed 115%. Anyone with even the most basic engineering or electrical knowledge knows intuitively that a system like this is simply harvesting energy at the expense of road users increased energy consumption.
Think of it as a toll or tax on roads that would employ this technology.
They still teach E=1/2mv squared in school, it's just that no one bothers to apply it.
I don't think that's the issue. It's that people not versed in engineering at all are being swooned by 'clever' marketing tactics
@@cberge8 Isn't 115% part of the problem? ;)
@@stusue9733 Not at all. Anything above 100% just gives you a perpetual motion machine/free energy device. I've seen a ton of UA-cam tutorials on how to make these so they must be legit. Lol
The fact that the creator has worked in oil and gas before makes perfect sense. This is an excellent way to increase fuel use.
and am amusing the faster the traffic the power it will make? I think I need reminding why speed bump where put on the road in the first place? the landing say plane? landing or something getting rid of energy eg speed landing would a good idea jet aircraft carriers use tow line that catches the planes as the land making landing area a lot shorter than without one?
@@dh2032 try again mate. you killed godzilla with that comment.
FR, I thought I had a stroke
@@dh2032the landing strip is long to allow the plane to slow down. Using a rope to slow it down would rip pieces off of it. Planes have to dump fuel for early landing because the mass could break off the wings.
Well they did say that they're aligned with the UAE.
Compression-absorbing boots for cows. I’ve calculated one cow walking across a pasture could generate 450-850 Wh per hoof. AND, if you cover the pasture in speed bumps it will double the energy output. Each cow will have blue lasers that coordinate cow movement to maximize power output.
Collect the farts too
Tech bros watching right now: 😲 is free real estate
I'm not even 40 seconds in and I'm already mortified. This makes the solar roads look like the product of sheer genius.
Loll they are stealing energy from your car at the very best
It's just making regenerative braking less efficient.

1. Violate the laws of thermodynamics
2. Profit
From my understanding, a "speed bump" capable of stopping 3 ton vehicle from 68 km/h to zero, must be 2 meters tall and made from concrete.
A sand/gravel pit would work too.
A sand and gravel pit will trap the vehicle and take up a lot of space. A brick wall is both compact and effective.
If not, then they managed to crate the star trek inertial dampener.
@@supernova743 but sand pit is reusable, I fear brick wall is getting close to one use disposable trick. Unless we build it real thick. Also I think it would be easier to trick people to drive into pit than a wall. We need more grant money to rsearch this further.
@@Taudlitz What if you paint a tunnel on the wall?
I get about 250 watt hours per mile in my Model 3. So driving over a single one of these gives as much energy as it takes to go an entire mile? Now I may not be the best at physics, but these bumps look considerably easier to drive over than to drive a mile, given that drag exists. If I drive over 5 of these, I get a whole kilowatt hour! So... It sounds like a perpetual motion machine. Just hook up some induction pad right after the bumps and we have infinite energy folks! We solved it! Maybe we can also put dynamos at stop lights and have cars rev while waiting for the light to change while we're at it.
Yep, I did the calc, 300Wh is the same energy as stopping a 3ton car from 94km/h down to zero.
you don't get it, they'll stop your car for 1 minute to run the wheels.
sure it's an abrupt stop when you're driving 50mph and you get latched on the device but think about it, it's energy you paid for and not the city, it's only right they ste.. tax your battery in an inefficient neck breaking manner.
Human nature dictates that car drivers will avoid places with annoying and property damaging speed bump zones for their own comfort.
@@EEVblog They are probably doing some bad math combined with wishful thinking.
E.g. Taking the maximum energy harvestable from a car then multiplying it by 2 (two sets of wheels per bump), then splitting a bump into two bumps so each wheel compresses one half-bump and multiplying again, then adding another bump in series and multiplying THAT... then going "But what if a car is a fully loaded VAN?"
Also, any energy harvestable wouldn't come from speed reduction but from the weight of the vehicle - you can drive over a speed bump at full speed without it slowing you down.
There's a speed bump I can see from my back window - people not minding the road (or their car) will go full speed over the bump.
The bump doesn't stop the car. It is not a wall. DRIVER slows down the car to avoid getting a kick in the ass and to protect the car.
These guys are also off in their calculation by the factor of shock absorbers - that's where the energy is already going when going over a bump.
Yeah, sure, the spring in their harvesting speed bump will store energy when a car goes over it - but so will the shock absorber spring in the car, that was designed to minimize the effect of going over a bump.
Also, rubber tires.
I had a moron run over my foot which was already in the road. I was standing, looking right, being careful and all cause I was holding an umbrella and it was raining - he ran by me from the left.
It felt no heavier than a regular sized moron stepping on my foot. It took me a split second to realize what happened as he just drove on down the street.
He was moving fast enough that all I experienced was a fraction of the weight of the car for a fraction of a second.
It hurt a bit but I just mentioned his mother and continued walking to school.
Same happens with a speed bump. Only a fraction of the energy as weight gets transferred. And the faster the car goes, the less energy gets transferred.
That's why people lose the grip of the road while going fast vs. going slow and why asphalt tends not to get depressions in the open road but will deform at traffic lights.
Has to be over a mile plastered with these bumps or something like this. Then you lose "only" a few km/h on each hit ;)
Note: they didn't specify what "one system" means, how many bumps, modules etc... basically a marketing lie.
To be clear, this device isn't capturing the energy from a vehicle slowing down - it *causes* that to happen, but doesn't capture that. The actual energy generated is coming from the vehicle compressing the speed bump, which would indeed be a tiny amount. So it does steal the energy from the car that's required to crest the bump and compress the hydraulic cylinder, but the energy that goes into slowing down *before* you get to the speed bump is either going to go into regen (for an electric car), or just get wasted (for ICE cars).
Doin' some math, gravitational potential energy for a 3 tonne vehicle moving down 10 centimeters is .. 2940 joules or 0.8 watt hours. You can run a microwave for 2 seconds for each passenger vehicle. Assuming perfect extraction, energy storage & AC conversion, you would need 60 cars to get their gravitational potential energy sucked out of them to cook a hot pocket
The housing for the generator had a solar panel on top. Something tells me that more energy can be gathered with that. lol
The one place this could potentially work (steep downhill roadways) is precisely where I don't want my ability to brake effectively being compromised by these things' reduced tire contact patches and the entire car bouncing up and down, loading and unloading the suspension.
Real fun is this. Several years ago our municipality also wanted to "experiment" with energy harvesting road bumps. I did the math based on the vertical movement of the bump and the weight of a car. Results were the same: useless idea. So I wrote a letter with the math. Luckely they didn't invest money in this experiment.
I guess, the marketing guys are just confused by W and Wh. The speed bump may generate 150-300watts for the split second, the car is hitting the bump.
I suspect so also.
That's like the PMPO "rating" for speakers x.x
It generates steady sustainable income for car repair services too. And, the more you car sits at a suspension repair - the less it drives on roads and less pollution. Combo!
Yeah, the only thing I could think of as he was explaining that energy cannot simply be created, only transferred, WS just the idea of how little that would matter to anyone wanting to employ these, since the added fuel required to continue at the same rate of speed comes out of my pocket, not theirs!
During my engineering degree, I stumbled on a newspaper article about "piezoelectric pavement", and submitted it for thoughts to my fellow students. My point was, "the energy comes from your lunch, and you'd be better off producing electricity on a bike with a dynamo generator". Amazingly, some of my fellows failed to see it was moronic, and said "well, the system can gain in efficiency so it won't rely on the walker's energy"... 🤦♂️
Humans don't generate that much energy. I already thought of a gym with a side-line in electricity generation. But it would only give enough power to run the lights.
@@vylbird8014 no, indeed, they don't, that was my whole point : bicycles with dynamo generators (which is a dumb idea once you really think about the little power it would generate) would be a much more intelligent thing compared to the "pavement generators"... which is saying something about the uselessness of the latter.
@takix2007
Of course, improving efficiency is the key! Simply design a 101% efficient dynamo and you're done 😂
An average gym goer on a bike could maybe produce 100w for an hour. Trained amateur cyclists maybe 200w for an hour, but let's use 100w. So if you have a spin class of 15 people, that's 1500w/hr. A bit more than the lights for the room, but nowhere near covering the hvac.
Yeah "unfortunately" for ideas like human powered gyms, human bodies are just way too efficient at using energy. :p
harvesting energy from footsteps from people who are just trying to get through their day without getting too tired, forgetting that gyms have dozens of people in them working out and trying to give energy away
Is there a good way to do that? OK stationary bicycle or stepper/walker excercise devices are pretty obvious candidates. A treadmill is not... really unless it's gravity based?
Ok this really sounds dystopian
@@SianaGearz You'd have to set it up so the runner was driving the treadmill belt, instead of the treadmill belt being spun under the runner. I'm not sure how practical this would be, but _maybe_ if you had some sort of shoulder-harness tether to stop the runner from moving forward, you could set up the treadmill belt to be basically free-spinning but connected to a flywheel (to preserve inertia and keep the belt movement semi-continuous) and a generator (to harvest energy). The bit I'm least sure about is how to set up the harness so that it doesn't interfere with natural running movement - I'd imagine the tether line would have to align with the runner's center of mass, at the least.
@@turolretar It _sounds_ dystopian, but I doubt any economically-realistic dystopia would mandate it, due to efficiency losses. The poor proletariat forced to work in "human energy production" would be consuming more food energy than the amount of electrical energy they'd be producing - you'd get much more efficient energy conversion by just setting food on fire directly. I think this only works in "dystopias" where even the underclass has a resource surplus, or in semi-dystopias (e.g. the real world) wherein you could get credit back on your gym membership fees from your energy production - making them cheaper or almost-free if you have the time and energy to work out regularly.
This is the thing. If you just draw a basic diagram with arrows representing the downwards weight of the truck and horizontal push of the vehicle you get a diagonal line. You cannot extract energy from the weight of the truck as it will weigh the same and so the only other place is from the push/momentum. If you extract momentum then the truck slows down (needing energy to accelerate) which means it needs to use more energy (and gas/electric) to speed up.
There is a quarry in Beil, Switzerland, this specific quarry is unusual, they load the ore into dumptrucks at the top and take it to the bottom. So they use the largest electric dump trucks, they drive off the batteries on the way up and recharge the batteries on the way down recovering enough energy they do not need to to ever plug these trucks into recharge. And this shows the rub, any location you could use this, an electric vehicle regen will be just as good if not better.
I think giant pendulums between major destinations is the future of energy efficient travel.
Imagine you if you wanted to step off halfway between the stops 😂
Reminds me with that elevator thing from Total Recall
Actually, some of the urban trains in Germany use something similar by having elevated stations so they decelerate uphill and accelerate downhill.

Great as always Dave. I love the bump test with the Mercedes, one of the most polluting cars on the market! Well done green roads...
something like that creates drag and it makes using that road less energy efficient, you will pay more gas to get a fraction of the energy captured.
Them darn laws of thermodynamics 🤔
Reminds me of a stretch of concrete test highway I used to commute on. You don't use concrete for roadways where the ground freezes solid in winter because it just falls apart at the joints and needs to be patched... So driving on that stretch of road was miles of THUMP THUMP THUMP THUMP THUMP THUMP THUMP..... it was especially horrible in a truck with a leaf spring suspension.
I was so happy when they tore that up.
The Lake Pontchartrain Causeway does this for it's entire length, so wonderful.
Solar FREAKING Roadways finally got a proper sequel! I love it!
This might make sense in cities as regular speed bumps that can power some speeding camera or something like that.
I like the "fist pump of excitement" you do in the air at 0:44 - it's fantastic how excited you are about humanities journey to net zero, and nice seeing you share your enthusiasm with your viewers. Keep up the good work Dave - you are an inspiration to us all... ;-)

0:32 That “yayyy!” got me. Brilliant video.
I don't know why they don't target motorway braking zones primarily. Over in the UK they put down these big yellow stripes that shake the hell out of your wheels in braking zones. It's a place where energy is being wasted because you HAVE to slow down, they FORCE you to slow down with the bumpy stripes, so why not install this stuff at these points where the energy being recouped is actually energy that'll be legitimately wasted otherwise.
The fake euphoria kills me… Too funny
Looking at the energy figures are they really assuming it will _literally_ be the only thing to stop your car? For a 3000kg car 150Wh corresponds to a speed of 68kph while 300Wh corresponds to a speed of 96kph. The only other organizations that have "speed bumps" capable of extracting that amount of energy from a vehicle are NHTSA in the US and NCAP in Europe. I think we are going to need more cars!
The simplest way I can think of to build such a system would be to put a long gas filled bladder (nitrogen or just air) inside the whole length of the bump. When something drives over the bump, it compresses the bladder and pressurizes the gas. Add a couple a check valves and you now have a gas pump. Store the pressurized gas in a big tank and use the stored gas to power a small turbine or pneumatic engine. The tank can store up the gas from each pulse, allowing the turbine to run continuously, and by making the tank nice and big, each pulse won't change the pressure much, which will give more consistent (and thus more optimizable) performance for both the pump and the turbine.
A hydraulic-pneumatic system could also be used, with the bump having hydraulic fluid inside which then operates a pneumatic pump close to the generator. The shorter run for the pneumatic circuit might increase performance or the switch to hydraulic for the bump might make the design more robust. It would take a lot of work to figure out if that would be worthwhile.
Of course, it would only make sense to install these in places where you already want a speed bump, and I think it's very questionable if the system would produce enough power to be worth-while. My intuition is that it wouldn't even pay off the energy used for manufacturing and installation during its lifetime.
This is going straight into my A level Physics lesson tomorrow for a discussion starter. Pretty certain my future automotive engineering student will be in hysterics.
That small trial footage reminds me of the cobble test road they used a lot in top gear 🤣
I watched this for one minute. Every watt this concept outputs is stolen (x2-3-4?) from the vehicles that pass over it. Impossible, next!
I remember seeing something about this quite a while ago. If you look at it from the perspective of an engineer it's stupid, but remember, the person who puts in the speed bump isn't paying for the gas that is being wasted by slowing the vehicle with a speed bump.
Speed bumps usually slow cars down by encouraging the person to use their brakes to slow down. If instead you had something that physically slowed the vehicle... more in the line of the slowing you get when you drive through a large puddle, then, because it was forcing the vehicle to slow rather than encouraging the vehicle to slow, you might get a better speed bump for safety, but energywise, yeah it's stupid.
I could see it being useful on some long stretches for large trucks, not so much for generating electricity, but as a way to save their brakes a bit and prevent runaway.
Except they already have something for that: The jake brake. Problem is, people are too busy complaining about the noise of the jake brake to realize that it is a safety feature and should be able to be used anywhere regardless of the loudness. I would rather be woken up in the middle of the night by a straight piped peterbilt using his jake brake than for said straight piped peterbilt run through a minivan and two sedans and kill three families because he lit his brakes on fire trying to stop and there aren't any runaway ramps nearby.
That sounds like a person doing the voice of Morgan Freeman (not Freeman himself).
Roads are dirty, what happens when it gets full of dust and dirt? What happens in the winter when water gets in and freezes?
Looks like springs and pumps in the road surface. A few hours of muddy runoff and it will lock solid.
Universities lining up to participate in the Hyperloop scam told me all I needed to know about the state of the educational system.
we have speedbumps all over the place here (Denmark), but if we did replace them with these, what would be the initial cost, maintenance and how much would it generate to offset that cost.
Assuming it works (on downwards hills), I would think it still will only be green if the energy it generates is worth more than the corban emitted from manufacturing, installing and maintaining the system as well, and I doubt that was ever considered.
I think they're claiming that if the system was constantly in use for an hour it would make 300wh of power. And it would be impossible to get a constant flow of cars that never stops. So what they actually mean is it will make
Also Downhill will not make sense for Hybrid or elecrtic cars : the energy accumulatded by the system is stolen from the rigen system of the car... ( minus inefficency )
Einstein said, "Energy cannot be created or destroyed, it can only be changed from one form to another". This first law of thermodynamics which also known as Law of Conservation of Energy works in all sphere of life.

11:45 good to see you subscribed with notifications 👍
Right off the bat I see this taking a toll on the wear and tear of vehicles.
This is the equivalent of attaching a diesel generator on a trailer to an electric car but with more steps.
Why are they speed bumps? Why not make the whole road out of them? And add solar panels! Solar bumpin' roadways!
You should do some traveling around the world. In Romania there is an extreme amount of speed bumps, every crazed parent request one to “protect” their child, in some suburbs there are roads with speed bumps every 100-200m, it is crazy
I wondered how long until Dave dropped “rouuted”.
Rouute is a perfect name for an investment harvesting device, if you ask me.
A highspeed speed bump?!?! That's what I call innovation!!! 😂
Isn't that a ramp?
@@icedriver2207 Nah, that's no innovation... 🤪 You need a merketing course, my friend. 😀
not that I am advocating for this device, but could this not replace any normal speed bump and have a net gain in energy without requiring a hill as the car would have had to slow down anyway?
All those mesh connection scenes… love how they use stock footage of a completely unrelated technology
Would it not be good for carparks or replacing existing speed bumps, or would the initial cost outway the payback term ?
The problem is that speedbumps (thus these things) get a very large amount of abuse. At best this system will break down very frequently, at worst it is an actual road safety hazard.
@PauldeVrieze I agree. I was thinking this would be a smarter way for them to market it rather than sticking them on main roads.
Priority memo to Purchasing! We need another 55 gallon drum of buzz-words!
You'll find energy harvesting with wind turbines at UK roads for road side installations (road signs, metering, ...). The speed bump could be used for traffic purpuse but there a non newtonian speed bump which are cheaper.
My dad is a power engineer and he says its a drop in the bucket. The C02. Says the biggest danger to the atmosphere is lawnmowers, unregulated mowers. He designed the scrubbes for most GE power turbines all over the world. He was hired by Italy to develop nuclear but Chernoyble sent us home. He is still working in nuclear.
This reminds me of the science project that the kids next to me in gr. 10 did at the university science fair which was to stick a ridge line wind turbine on a car. Their excuse was that a lot of cars were boxy (at that time) so it wouldn’t make much difference in terms of fuel economy… I was pretty sure you’d be taking more energy out of the movement than you’d recover in electricity. My project was 3D TV, also impractical but did eventually come to market!
They are doing this to get government grants. This is a highly efficient mechanism to transfer dollars from taxpayer pockets, into their pockets.
And if it was build it would be a highly inefficent tollbooth.
The bumps remind me of Mexico City where I was just on holiday. Where fast roads change to slower speeds like a toll station on a highway, they have lots of small bumps on the road forcing cars to slow down.
Just love how Dave used logo of boyband Busted in his thumbnail :D
Snake oil salespeople are alive and well! This generation claims to be honest compared to mine, I am 65. Thank you for the great video!
There is a reason that we don't put speed bumps at the bottom of hills: You don't want cars to pile up in start and go traffic on a hill if avodable, a speed bump at the bottom a hill will exasperate this problem substantially.
Revolutionary idea for these guys, instead of taking the energy from the car, just go straight to the source, hook up an engine to a generator and that's going to solve our power needs, we could distribute these stations where it's feasible but also distributive to prevent losses and vary the generation based on demand and not need storage, could call these places power stations, probably more efficient motors than car engines but that's for r&d to work on.
Would you really want complicated machinery installed into to your site entrance and exits? What if it breaks or needs maintenance, whats the downtime then?
The thing is this could work if its installed in locations that call for speed bumps anyway. It's taking energy from your moving car anyway so installing them where speed control is desired makes sense. I highly doubt even then it'd be worth it, though.
looks like a big version of those flashlights you can squeeze over and over to power them, some wheel inside spinning :D
alternative: put smooth ablating rails alongside roads so that stopping cars can come scratch onto them to brake
3:17 them showing how the energy can be used to charge electric cars had me rolling :D
Can they guess where the energy comes from? Oh man...
The whole problem with all these things is "or can be stored for later use" The public thinks that this will happen in the next 5 years without realising that we are out of options when it comes to storing, they will never improve to the level we need to do net zero.
The only place I could see this working is on highway offramps, but as you pointed out, people would get really annoyed at their cars bouncing around! Also, as EV's become more common this would have a negative impact on energy efficiency. It's way more efficient to recharge the EV battery with regen than it is to try to harvest it through speed bumps.
As a car shock absorber company I would invest into this.
Reminds me of Rick's car battery from Rick and Morty... The stomp boxes. LMFAO
P.T.Barnum would be so proud.
It's a stairmaster for cars!
Anyone ever used one knows just how hard work it is!

I can think of once use and that's on off ramps of motorways, they have rumble strips as you approach the roudabout the could replace those with these and enough cars would generate some power. Just a thought
Someday grandparents will tell their kids they walked to and from school uphill both ways. Soon nobody will finish the New York marathon. These things will replace the moguls in the Winter Olympics.
I went into this assuming they were harnessing the constant pull of gravity on it. That would make the conversion only directly related to rolling resistance, not any of the inertia or atmospheric effects faced by vehicles. Why would you be limited to downhill then? Or am I missing something?
What about replacing existing speed bumps? That seems worth it
In Brisbane we have so many speed bumps. Even at the KFC drivethrough. At the Coles in Deception Bay they have four back to back. Here we will generate more power than the sun :)
I see one use case for a simplified version of this..gates. You get a speed bump combined with a gate lift to allow gates to use little to no power.
My system actually works.
All thats needed is an arm to block the road, and a container to hold gasoline.
The arm blocks a major road. To make it lift, the driver needs to transfer one gallon of gas from their tank to the receiving tank. At the end of each day the gasoline is then used to create electricity.
Road based electricity solved.
