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 KZfaq tutorials on how to make these so they must be legit. Lol

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.

It's just making regenerative braking less efficient.

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

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?

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.

It's the surplus free energy generated by all the bounce-bounce-bounce.

@@IlBiggo 1. Violate the laws of thermodynamics 2. Profit

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!

I suspect so also.

That's like the PMPO "rating" for speakers x.x

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.

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

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.

​@@dirkvornholt2507 I can't remember which, but at least one of the early tube lines in London did this too. Regenerative braking before there were power electronics.

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.
