@@humbleindian6303 Odd then that Alex Graves in 2021 reported that while India had tripled their Highway System over the past few years those roads are "lower quality, narrower, less well maintained" so India's roadways were given a "Terrible" status on a Global Scale. This matches with friends and workmates from India along with management teams that regularly travel to India and have to drive over those roadways. Shops around the world that repair vehicles and replace shock absorbers along with other suspension components would likely strongly disagree with your assumption. Better solution to shock absorbers that waste that energy would be systems that capture it and pump it back into the battery. Easier now with all the pneumatic suspension systems being used today along with the reservoir shock absorbers having external accumulator tanks and hydraulic lines. Best!

[@joergmaass]

Dampers are, essentially, hydraulic pumps. You could easily hook them up to a central reservoir und equip them with one way valves, thus creating a hydraulic circulation system whose kinetic energy can be harvested by a turbine or something. Citroen pretty much had such a system in place with the hydro pneumatic suspension in their DS, CX and C cars. This suspension was fantastic and unrivalled by anything on the market today, even electronic suspensions. It was purely mechanical, no or very little maintenance required, and it worked like a charm. Unfortunately, it was also expensive, at least more expensive than normal suspensions, which is why Citroen unfortunately killed it. I'd love to see a modified hydro pneumatic suspension in a car again, and quite frankly, it would be a big reason to buy that car. If it recuperates energy otherwise lost, even better!

[@clivestainlesssteelwomble7665]

The other method is to use piezoelectric generator. The other way is to use the Citroen 2CV interlinked system and use active resistance damping and regen likebon a opposed shuttle piston with liniear field generator.

[@JoeyBlogs007]

Potentially a great idea. The issue is the power it generates Vs the weight overhead of the device. If it can be made light enough, perhaps it could be worthwhile. However it would also need to be durable. I think it could be costly, as it might need to be made from titanium for durability and light weight for power surplus viability.

[@Mrbfgray]

Doesn't need to be made out of any particular material, that's silly. But correct otherwise. Start with: "how much energy is available?" Do the shocks on your car get hot? Shocks absorb essentially all that energy dissipated in any suspension. Off road racing vehicles may need small radiators from extreme stroke, frequency and velocity of suspension action, but you've never heard of anyone burning themselves on the wimpiest shock absorber from the worst abuse on normal cars, at most they may get slightly warm. That's a crude measure of energy available, very little reward possible under normal driving, so the system would need to be nearly as inexpensive as regular shocks. Wouldn't look anything like this demo and wouldn't harvest much energy. Cool idea tho.

[@UnexpectedBooks]

Fortunately, “energy harvesting” is fairly mature. I suspect there are numerous material and fabrication options to exploit.

[@chrismuller2780]

@@Mrbfgray They don't "harvest" energy from the heat, silly, but the kinetic energy of the dampers. Watch the video demo again, notice the lights *instant* reaction of the lights coming on, much quicker than heat transfer. The dampers are powering some sort of generator.

[@sesmeltz1965]

@@chrismuller2780he’s pointing to the heat as an indicator of untapped energy. If something is being acted upon by a force without a way to transfer that energy, it will heat up. It’s not about capturing heat, it’s about converting kinetic energy to electricity before it ever becomes heat. Brake discs in an ICE car get SCORCHING hot, which is an indicator that there’s a lot of untapped power there. So it’s a ripe target for regenerative braking. Of course regen brakes aren’t powered by heat, they’re powered by the energy that was otherwise being lost as heat. Suspensions, on the other hand, don’t get that hot because they really aren’t losing all that much energy. So while we can tap them through mechanisms like this one, there’s not that much to draw from.

[@Mrbfgray]

@@chrismuller2780 You entirely missed the point. Energy comes in many forms but the most common default is heat, *that's where suspension systems today* dissipate the energy to dampen rebound. THEREFORE; heat generated, in the case of current cars it's in the 'shock absorbers', IS A MEASURE OF ENERGY AVAILABLE. Understand? Obviously you want to avoid turning it into heat you can't use, some will always end up as heat but in this case you want to--say intermittently light an LED strip, lol....and that's about all it could do, realistically.

[@peteinwisconsin2496]

Some numbers of interest: 1kWh of energy, at 100% efficiency is obtained by lowering/raising 2,655,200 pounds of weight, one foot. A 5,000 pound car, raised/lowered 6 inches, for 1,080 cycles, is the same as 2,655,200 pounds x 1 foot change in elevation. 1,080 jolts of 6 inches x the entire weight of the EV, while traveling the range of the EV, just to put 1kWh of electricity (for 3-ish miles of range ) back into the battery is nuts. That would be at 100% efficiency, but if you did reach 100% efficient, the vehicle would be bounced off the road or the wheels would be slow to return after one of these many, many 6 inch jolts. Suspension regen is not going anywhere with our present laws of physics.

[@alexfunk2047]

The amount of energy potentially yielded by this process can easily be determined by measuring the temperature rise of the shock absorbers. It's not much.

[@Tom-dt4ic]

@@alexfunk2047 Or you could just use math, as the above post demonstrates.

[@sb6489]

Like probably millions of other people, I thought of this years ago. It definitely does make sense. The role of a shock absorber (damper) is to remove vertical mechanical energy, traditionally by friction losses to heat. A magnet moving through a coil of wire, suitably controlled, can "loose" the energy via electric power into some kind of electrical energy load, like ... the battery.

Interesting concept! Even if this model shown doesn't work out, I think it can create interest and encourage research into inexpensive, lightweight methods of converting the dampening into electricity.

[@anthonyxuereb792]

Well overdue but how many will adopt it? Another way to store energy is through a horizontal fly wheel which is engaged when you press on the brake pedal to stop and so storing the energy that would have been wasted. Then when you take your foot off the gas spinning heavy mass the fly-wheel engages and propels you forward without having to use fuel, saves your brakes to. Very similar to the old tin plate toy cars with friction drive that worked really.

One of my son’s engineering school projects was to improve the efficiency of a vehicle greatly reducing the suspension in a vehicle. It rode like hell, but it did save energy. This is a great idea. And yes, a lot of people are very very stupid.

[@itekani]

Really? By that you mean reducing suspension movement made the car more efficient? I would have guessed the other way around. Then there may be a reason Teslas are quite stiff.

[@larzlarz1140]

It totally makes sense. This is brilliant. In early iterations, this would provide the baseline dampening and meteorological dampening (magna-ride) could provide any additional dampening needed. In later iterations, They could build this damper with variable resistance, based on accelerometer feedback from the computer, completely eliminating the need for friction creating tube shocks.

[@MaciejBugaj]

The spring is giving back the energy after the bump, by 'lifting" the car back to its original lvl above the ground. With this tool, the energy is taken for electricity, so the car will stay "lower" - or some other force needs to applied to lift the car back to original place. On the video we can see the man is pushing and then pulling it back, he is applying force in both direction = no extra energy from that action minus deficiency of any energy conversions. So I even guess that this proof of concept is loosing more energy than a string.

[@MTerrance]

I like the idea. Adding resistance to the movement of the suspension would change its behavior, which implies it would likely act as a damper. That leads me to wonder if it could replace shock absorbers. That could be a serious improvement, assuming some form of control to adjust how it behaves. Yet another analog system being replaced by an electrical system...

[@istvantoppler5999]

Excellent idea. Thank you for pointing such things out. Refreshing to hear actual common sense

[@electricviking]

My pleasure!

[@gaspererjavec1455]

I worked on a similar prototype that did almost the exact same thing, there is not a lot of energy you can get on such small vehicles. And powering those led-s is trivial. The only way this could be implemented in actual cars would be with a coil in the shock acting as the damper and a strong magnet as the piston, so you can replace a existing shock and not change the whole industry behind it.

[@sansabh]

The coil spring system would be much more efficient - and cheaper

[@1swaggy1]

Yes, Grest idea but already implemented. I heard of other companies toying with this other than BYD. I would also suggest it be introduced to caravans, trucks and electric bikes.

[@llee4225]

While some energy can be recovered from the magnetic suspension system, another advantage or benefit that is missed is using for variable damping to have soft or firm ride and firm cornering by varying the energy absorption.

[@dwcola]

I believe there was a magnetic suspension a decade ago or so that was designed to recover electricity but looks like it never made it. I think it's absolutely useful. Try to push a shock in at your local auto parts store. It's almost impossible yet, each tire does this thousands of times per day. Imagine recovering 10,000 shock compressions needing the force of several hundred pounds. That's Massive energy. Probably the same if not more than regenerative braking because its happening all the time except for when at rest which is like 1% if the tine at a stop light.

[@geemy9675]

active suspension is the next revolution in cars. recuperating energy from the suspension is only a small part of the equation, the bigggest gain in terms of engineering besides all the comfort, and handling advantage is NOT LOSING energy. when you hit a pothole or speed bump all the energy that gets dissipated in the suspension is also removed from the kinetic energy of the vehicle. have you ever riden a skatboard or roller blades on a very bumpy surface? it sends a LOT of vibrations into your legs and its is slow AF. all vibrations get transmitted by rigid elements to your muscles and they are dampened. A perfect predictive and active suspension that reads the road surface ahaead and reacts very quickly to variations in force applied to the suspension, and move the wheels up and down accordingly while maintaining the suspended parts of the cars perfexlctly level means the amount of energy transferred to/from the road is greatly reduced. instead of moving the whole car only the unsuspended components do, and the 4 tires keep pushing almost comstantly on the ground. this also means vreatly reduced mechanical fatigue and vibrations on all the componemts like suspension arms, axles etc. recuparating energy whenever the suspension is traveling up is the cherry on top, that will reduce the active suspension energy consumption, but overall its important to realize energy spent on active suspension is NOT lost.. people who argue that active suspension use too much enery are missing the point if you wanna think about it differently its same as pumping with a rigid bmx on a pump track. you are the car and the bike is the wheels/suspension. It takes energy (you'll be tired after doing many laps) but moves you in a much more efficient way than if you are sitting straight on the saddle and pedalling on a full suspension mountian bike on the same track suspension robs a lot of energy. now if the same pumping action is done through electric motors its even more efficient. Again, adding recuperation is even better but its cherry on top. By the way, its possible to combine active suspension with traditional springs or even air shocks, which are able to store energy and release it, an can reduce the strenght requirement on the electrical components. air suspension advantage is you can keep the car/truck level whatever the weight distribution is, in a passive way (you just adjust air pressure initially). the only part that absolutely needs to go away in active suspension is dampers, which are converting energy into heat, pretty much like friction brakes

[@JensPilemandOttesen]

Great idea. But seems like it could be engineered simpler. A magnet moved up and down inside connected coil will make power and dampen the movement. Also you control the stiffness.

[@jensbiederstaedt8022]

Perfect for Canada, the roads are so miserable here.

[@FrancisFjordCupola]

The questions I'd have would be (1) costs, (2) maintenance & reliability - because of the moving parts, which I don't expect to be any big factor since you'd always need moving parts there, (3) room and of course (4) how much energy does it produce. If you have extra weight from the device and from the cabling it first has to make up for that. At any rate, these kinds of devices are rather welcome.

This is a total no Brainer. How long did you say? 10 years? --This is a possible within a year. - Simple & superb!

[@chillfluencer]

No. Think of it: recuperation actually brakes. This means if you would want to get energy out of dampers they would go stiffer while dampening. And that would be close to as nasty as having no dampers at all. Recuperating e edgy from a motor so it brakes makes sense. But making the dampers getting harder while they are dampening is counterproductive...because the dampening effect would get reduced and you'd be thrown around in your car like crazy.

[@christophmartin5381]

Audi created years ago an energy recuperation system for their suspension. Can not remember if it was for the A8 or any other model. Energy reflow was indeed some percent. Especially when the car drove curves.

[@yodaiam1000]

It is hard to find information on the total amount of energy lost in the suspensions but it looks like a typical numbers is 200W. So if you can get back 160W, that amounts to about an extra 1% of range. Is the extra complexity and expense worth the 1%? If you drive a car 300 000km before it is dead, that amounts to an extra 3000km of range. That is about an extra 500kWhr of energy which is about $25 to $60 USD depending on where you live. Is the added cost of the suspensions less than say $25?

[@Wiscotac]

[@bsaxman2012]

Seems like a very good idea. Curious if the amount of electricity generated is worth the cost, extra weight, and maintenance/replacement when the devices wear out.

[@user-vp1sc7tt4m]

We want to reduce (damp) motion in the "bump" direction (normally up and down, not forward) which requires energy to be absorbed by the vehicle damping mechanism. This reduces the vertical up and down motion of the vehicle but also absorbs kinetic energy from linear vehicle movement. Imagine a vehicle with NO POWER TRAIN and on a hill. JUST a dead weight. Release the dead weight vehicle down the hill on a smooth downhill road and compare on a very bumpy or undulating downhill road. The vehicle released on the smooth downhill road will reach the bottom much quicker because the vehicle on the bumpy downhill road was spending a lot of time in vertical motion navigating the bumps or, it's suspension was absorbing forward motion energy to compensate for the bumps, which slowed it down. Attempting to capture the bump energy and convert the dump energy into forward motion would result in conversion energy losses and with no gain in available energy in the system. It's like, capture the energy from the bump and the suspension gets harder which negates the damping affect of the suspension... that doesn't seem to add up at all. I may be missing something but basic logic implies a suspension regen system will not help much at all.

[@user-vp1sc7tt4m]

A suspension system which could "sense" bumps and sort of release the damping mechanism with millisecond response times may save energy. I think this already exists but I'm not sure where.

[@alexandermelbaus2351]

The whole idea is stupid and won't help anything. They also have the idea of efficiency backwards; If Petrol is only 20% efficient (The claim is always made low) and the stated high efficiency of electric propulsion system at 80% or 90% efficiency still can not compete; That is a bad statistic for electrical propulsion. Efficient this and efficient that; So efficient they are starved to save even the smallest fraction of energy, that even the dumbest ideas appeal to them.

[@dc14522]

[@user-yi8uu1du3b]

I've thought about this for years, though I thought linearly. Though I think that set-up is over-complicated. A simple PM motor should generate some volts if rotated, and with rectification would provide DC regardless of direction. And active damping would be relatively simple. No doubt some gearing would help to get the rotation at the optimum level, much like the on in the video.

[@samblum153]

Regenerative suspension is a wonderful idea! I'm biased though as I worked out the concept long ago. I worked enough of the math out to figure that in time we'd get there. Glad it is being done.

I was told all those things brought up as 'criticisms' about the suspension part too. Since it was 1971, I pointed out that given the obvious exponential growth in tech, it was just a matter of time. Sam! The 1st time I remember hearing older folks talk like you did about the youth I was about 6. Granddad noticed the look of distress on my face, pulled me away and told me that the 1st time he had heard anyone talk like that about 'the youth these days' was when he was a kid too. He told me it was part of how older people that had issues with finding joy in the joy of others (basic jealousy there) & had been conditioned to making themselves at the expense of others, (basic bigotry-badcode), do that to keep themselves feeling relevant.

The concept is real. The movement of suspension pieces is wasted energy. Much like friction brakes & suspensions shed the energy as heat which is then lost to the atmosphere. If that suspension movement can be captured and converted into electricity it would make EVs even more efficient. ICE vehicles have alternators to generate electricity but EVs do not have alternators. This would be a way to generate energy without an alternator which EVs don't have anyways. There are no mechanical belt driven systems on an EV. Instead of generating energy from the crankcase like an ICE vehicle does you would create it from the mechanical movement from the suspension. Unlike ICE you have the ability to store large amounts of electricity in an EV. GM actually had a concept car many years ago that generated power from the suspension system. But it was not seen as practical at the time for ICE, because ICE did not have the need for more electricity. Gig Performance still has a long way to go before this is ready for the retail market. The only practical system is for big rigs. They usually always need power to run their refrigerated loads and onboard systems. Most places in. the States they can no longer idle in place. Many already have a hi-capacity battery onboard to keep some systems running. They have to develop one for lighter vehicles like cars and light trucks. Currently the effect on ride quality is profound, and not in a good way.

If shock absorbers could recover the level of energy one would even notice in an EV, then standard ones would already be red hot due which is obvious not the case. I’ve popped a shock absorber on a dirt bike from boiling the fluid before, that day was the hardest I had ever rode a bike. But then again a 100w heating element could do the same, as a fraction of the 40-50hp the engines putting out, that’s nothing. It would only make sense as an active suspension device if it could be made to perform better than hydraulic and the energy recovery is a side effect. But likely the extra weight and poorer damping characteristics would actually reduce range not extend it.

If they can keep the weight down i can see this being utilized on hybrids too.

The complexity, weight, and cost of this ‘technology’ would make it unviable.

[@sergiotonetti3657]

there is a toy call'd spinning top that could make the simple dynamo build in the suspension

[@SteveWindsurf]

Does your car shock absorbers get hot whilst driving? If yes, then energy is being wasted. Expensive Active suspension units can already regen.

[@dougowt]

Some adaptive suspension systems use electro magnets. These would surely be the easiest systems to modify to recover energy from suspension movement.

[@humbleindian6303]

stupid idea to restore suspension energy since the roads are not bumpy anymore not much efficiency improvement , you loose efficiency with additional weight and increased complexity

[@jetli740]

weight +cost VS energy produce see which win.

[@RagnarinVa]

So finally potholes will help generate energy. New Jersey will be in heaven. :)

[@doobster6783]

This absolutely will work!!! And yes, it is total genius on this guy’s part to recognize that the kinetic energy being dampened in the up-and-down motion of a 4,000+ lb car is anything but trivial! Each arm operates a ratchet that spins a generator in the same direction, bump after bump so that this previously wasted energy is now reclaimed. This could be on the market in 5 or less years methinks…..

@@doobster6783 it good idea but the main issue is weight and complexity VS gain car suspension rarely travel that far as demonstrate in the video + how often ur suspension work that hard i think gain would be very minimum VS weight and cost

[@mrbaab5932]

The alternator uses power from the engine and make the engine work hard and burn more gasoline to charge the battery for gas cars. For EVs this device can charge the battery, but in needs an inverter to reverse the charge half the time ⌚.

… I think it would make more sense for a region device, if it’s built into the shock absorber!

It can work, but the problem is: does it make economical sense? Will it recover enough energy to pay itself over time? Adding extra weight to the car is it going to negatively affect range more than the energy it is going to recover?

[@ArielBatista]

That's a great idea, also seems like it would work for a wave generator.

[@brucewiggins2731]

I have an electric scooter which has regenerative braking and it is has been sugested to turn it to low as it does no good for the motor , also this was used on a drop saw to slow the blade after cutting ,it did no good for the motor also.

[@jameskassolos4652]

if it works its a game changer, your looking at four generators one on each wheel working all the time the car is in motion. Has anybody tried this out yet?

[@oldguy4057]

From an engineer: It may be complicated, but it should work. Hydraulic shocks do get warm, showing that energy is being produced. This might be combined with an active suspension system that reads the road ahead and prepares each wheel for the oncoming bump. Congratulations to this young man.

[@larryevans6739]

Look up the Disus-Z system on the production BYD YangWang U7. Uses linear motors for active suspension and regeneration.

[@incognitotorpedo42]

Lots of things will "work". The catch is that you have to get enough energy out to pay for the added cost, weight, and complexity.

[@incognitotorpedo42]

@@larryevans6739 BYD's system is mainly for active suspension. They would not have done it for regen alone. It doesn't pencil out.

There have been several different prototypes by various inventors based on this concept over the past decade or two. None seem to have been commercialised as yet.

Yang Wang U7 is the first to commercialize it, using linear motors.

[@timogronroos4642]

Great idea, just put your Tesla into camp mode and then go to the backseat to charge the battery...

[@anomamos9095]

The problem has never been about capturing the waste energy from braking and the suspension systems it has always been about how much energy is wasted in capturing the waste braking and suspension systems . The law of diminishing returns dictates if something is viable or not. ICE vehicles usually don’t have regenerative braking systems not because there isn’t technology available to do it but because the mass and complexity of such systems cost too much in energy. If it costs one kilowatt per kilometre for an ice vehicle without energy recovery but two kilowatts per kilometre for one with due to the extra mass, the recovery system would need to recover much more than one kilowatt to make it worth the extra cost . In most cases the systems recover less than what is spent just carrying them around. EVs have an advantage as most of the energy recovery system is what moves the ev in the first place.

[@Gawriify]

if you live in a city like NY where the roads are absolute shit.... sure you hit potholes all the time so i can see it working... but how much does it cost to produce and install... what is the overall energy output by this device over a week or a month of driving... how complex is it because adding more and more devices will make cars more complex and will introduce more and more things that can and will break.

[@aloisiussi4635]

Put on bed, on a bed for couples to be precise, also can regenerate energy 😂

[@robvannNS]

Similar systems used to capture energy from ocean waves.

[@user-vp1sc7tt4m]

A vehicle propels itself down the road linear to the Earth's surface. Let's call the energy required for propulsion with no bumps (undulation) in the road and no hills "E". If the vehicle encounters an undulation at speed, the suspension dampers absorb some of the energy which the "bump" undulation impose on the vehicle perpendicular (approximately) to the direction of travel. If there were no damping system, the "bump" undulation would require more energy from the linear drive system because EACH BUMP IS LIKE A LITTLE HILL which must be overcome. The "damping" system absorbs some of the bump (perpendicular to linear drive) energy, reducing the linear motion drive energy required to keep the vehicle moving. Think of it this way - hit the accelerator on a smooth road, little suspension loss. On an intentionally built wavy road or what I know about on major pot holed roads, the engine is working hard to overcome the EFFECT of the suspension trying to smooth out the ride. If you "capture" the EFFECT of the suspension energy, you are in fact, reducing the suspension DAMPING. I'll leave it to you to figure out from here. This is not the same as capturing ocean wave energy (although... take energy from one place and it affects another does come to mind because energy is never lost, only transferred). What law of thermodynamics was that?

[@lekcom62]

It`s all about weight maybe if it were carbon fiber yes and next one cost will give more power over it`s life for what it cost`s i think maybe each wheel have a lite weight alternater that is not making contact so as to no fiction might a better option .

[@1voluntaryist]

Aptera has "motor-in-wheel" to save weight and increase the motor efficiency. What will the region by suspension weigh? Will that offset the extra energy?

[@greghudson9717]

There's a disadvantage of motor in wheel as well... It's called unsprung weight.

[@mavelous1763]

We need dampers on fault lines

[@user-vl5cg1zi4m]

Maybe a better way to apply this tech would be thru the shocks and springs and using the brakes conversion mechanism?

[@sansabh]

Only marginal power regeneration - I don't think it's much, but some is better than none

[@bkparque]

Didnt bose have a system of inverse damper that recovered energy?

[@larryevans6739]

Yes. The idea is not new, but the problem in the implementation. BYD is the first to bring it to market with the U7.
