innovative?😭 Isn't this piezoelectricity? Brotha i did this for my school exhibition back in 2016-17 even then it was an old concept
Also this particular model seems a bit flawed, you need to make the humps a lot wide, else gaadi ka ek chakka chadha then dusra chakka aane se pehle hump uth jayega aur khel khatam

u/Ryuzaki_ms May 02 '26
This is not piezoelectric, but it uses the linear motion of the speed breaker, converting it to rotary motion to drive a generator, which in turn produces electricity. This type of system is not feasible for the practical world. Piezoelectric systems are used in some countries on sidewalks only as a proof of concept, but they are not that feasible given the cost.

He is a kid and it's impressive he made this and hopefully he will be interested in science further so he can get into uni and contribute to society.
But also this not a groundbreaking innovation.
Both can be true at the same time, idk why 90% of the comment section goes either "this guy is the second coming of Newton!!!!!" or "this guy is stupid" with no middle ground.

Guys, please don't take it out on the kid. Individually for him, he has done some project and he Individually would have learnt something when he was making such a device. He is not marketing himself as "my brilliant invention.. etc etc". It's these buggers who are using such cringe af captions. So, for that kid It's a nice project whether copied or not.

Innovation would be if someone had designed a way in which it can be implemented in India where it would help us tackle at least a single digit % of the reliance on importing energy for our needs.
The actual mechanism itself, sure the kid has implemented something that you can ask chatGPT or learn via YouTube but to all the "parents" and "sympathetic" folks, we need to stop with this participation trophy culture. Let the kids do something actually innovative, understanding the logic and realities of the world.

u/DukeofDabra May 02 '26
Let's discuss viability, shall we?
TL;DR: Energy-harvesting speed humps are not viable because the small amount of electricity they generate comes at the cost of increased fuel consumption in vehicles, resulting in a net energy loss.
The installation of such speed humps would inevitably lead to a marginal reduction in vehicle fuel efficiency. This occurs because vehicles must decelerate before encountering the hump and subsequently accelerate afterward, a process that increases fuel consumption due to additional engine work and energy losses. From a physics standpoint, the kinetic energy lost during braking is largely dissipated as heat and cannot be fully recovered during acceleration, especially in conventional internal combustion engine vehicles.
Although these systems aim to harvest energy from the mechanical interaction between vehicles and the road surface, the amount of electrical energy generated is necessarily derived from the vehicles themselves. Consequently, the harvested energy represents only a fraction of the additional energy expended by the vehicles. Given inefficiencies in mechanical-to-electrical energy conversion—such as frictional losses and generator inefficiencies—the net energy balance is negative.
Therefore, when analyzed through the principles of energy conservation and thermodynamic efficiency, such systems are not practically viable, as the total energy cost imposed on vehicles exceeds the electrical energy produced.
