The Future of Renewable Energy: Piezoelectricity | Akshat Kothari | TEDxYouth@RWADubai

[@raavanpandey5043]

No, the data given by him is wrong. Piezo has high internal resistance, making it a low current generating device. The range is in micro-milli amperes. With this, it would take 70000-90000 hours to charge a cellphone and not 1-2 hours.

[@danielmasekela7091]

I agree with you

[@muhammadkhattak802]

@josephvibhumusic what was the cost of one palte and can u share your report with meh

[@muhammadkhattak802]

no it will not take that much

[@Potus4547]

5:35 - did this guy sneezed inside him? Genius !!! :)))

[@anilsharma-ev2my]

Put all the piezoelectric circuit under your sofa and bad and cushion and all round the pressure point so we got electricity by our own function Under the water tank so when it's become full it gives out electricity and after that

[@lasarith2]

My math may be wrong, but I believe he would only get Approx 15KN of force on any piezoelectric device /second embedded in the road probably much less due to the surface area of the tires contact and time of the car on the piezoelectric device and the weight spread across the entire car, This is a guess but anywhere between 5000-50000 volts for however long the tires contact the piezoelectric 1/27th of Second .

[@aimanahmedmoin3795]

Though the data has some flaws, but the idea is brilliant!

[@kociamber149]

Aiman Ahmed Moin though your grammar sucks, but your sentence does too!

[@hemrajchaudhary7298]

these piezoelectric material can be used in suspension system of the car which absorb the vibration & convert them into the piezoelectricty but it is not efficient, the electricity will produced in micro volt amount thats the major disadvantage of this. I have done this experiment & further working on it to improve. if anyone has any good idea to improve it, suggest me please.

[@anshumansahu5485]

On an average what is the efficiency of a Peizoelectric device (disc to be specific)?

[@paulalcantara6926]

I'm no expert when it comes to piezo but i think you should use an amplifier. Hope that helps

[@sarveshmane298]

We can put on the shores of ocean to generate massive pressure of waves

[@jasonleerobinson1]

It could be possible to integrate a wireless charging circuit and set the power to offload at specific sites in the area to harvest the power and share it across the grid. Would reduce cost of plate installation in the street while allowing each community to power itself with similar resources

[@thinkbeyond5360]

I'm making a piezo electric tiles.. Its very difficult and it's bad

[@stinshasteephan2272]

Hii, can i ask a doubt, is there any disadvantages by the use of piezoelectricity😊

[@kihondosa4]

rather reclaiming back the energy towards higher efficiency. There are way better ways of harnessing electricity using piezomaterials but nobody wants to bring them up, forsome reason.

[@acewmd.]

Alex Kostko I would like to know

[@mrrafi4]

Current output is minute around 20 micro amps for one crystal ...his data's are all wrong..

[@alextai1652]

i'd like to know too

[@7777PEACEMAKER]

Bravo young man

[@yoggupta4295]

Bro, what about the energy required to produce such a massive amount of piezo-electric devices at factories?

[@lealguera]

piezo electric cristals are produced every single day, they are more common than watches, cars, computers, cellphones.

[@iwanschani4339]

@@lealguera what do you piezo electric crystal been produced everyday ?

[@Piccolo_Sun]

i have improvement need to get my hands on one of those plates to test

[@jrsmithe9391]

Did you ever get your hands on a plate to see if your ideas of improvement works?

[@Piccolo_Sun]

@@jrsmithe9391 i have become a god since this comment this tech is a baby joke compared to real Renewable Energy that was used in Kemet

[@ALee-sf3ls]

harnessing waste energy. My Question is how much energy can be harness from piezo material vs electric motor generator.

[@akashgawali300]

It's depends on size of piezoelectric plate

[@samuelsiregar693]

How come he calculated 150000Newton ? Is it possible to make a car running 100m/s in 1 second ?

[@ryankc9558]

Samuel Siregar he’s saying over the course of one second, after getting to the speed of 100m/s it will continue to deliver 150000, of course there are numerous things he didn’t calculate, fundamentally it’s a good idea.

[@ramakrishnaniyer889]

Yes.. a basic flaw in the argument

[@dannyjix5122]

I think it's batter to have some energy then having nothing. I'm sure the data he gave is wrong but it's topic of my project about the piezo electricity that's why i watched this talk but I don't how he stored the electricity. is there battery or power bank or what??.if any one know answer pls help me about this one.

[@arimukh28]

Dude check out the shoe contraption closely. He did say that he used a powerbank to store the energy.

[@filipen.9522]

whats the name of music in the beggining of the video?

[@anilsharma-ev2my]

Use hydraulic for making piezoelectricity So we restore deas battery of cars

what is that tones on the very first part on the video. I heard it radio earlier today.

wonderful tonight

[@peterfrebold]

... I may have missed something hear but why not incorporate this in the springs in the car and charge the electric car ..... laughing ... then we would want rough roads to get more spring flex ...

[@danielmasekela7091]

The electric charge produced by these crystals ranges from micro -milli Amperes.

Whatever happened to this, I am curious how much more has he gone about to learn about piezo

[@imlej5260]

i thought the intro was an ad

[@satisfiedsushi5329]

i made my own charging shoe for the science fair. sadly i really didnt get the voltage i wanted :(

how much voltage did you get? and what did you use? Please reply! Thankss!

[@lagalex]

why not making the roads like this in order to save the energy in a central battery bank in the neighborhood so every car and everything that moves gives back energy. Bad the goverments has to aggree and do it :P , so personal system is fine but a massive would be more efficient if possible to be done :)

[@MrSanktjakob]

Roads has to be extremely durable and cheap. It's not viable to implement energy collection in roads.

[@muhammadqusyairie7466]

Presenting applications leading to a lot of questions. Huhu.

[@muhammadqusyairie7466]

Need to adding a little a bit longer in part of introduction to piezoelectric effect.

[@smahns]

no way your shoe could charge your phone even to 50% in a few hours

[@weistrass]

That data given is not right at all.....

[@nneerraajj2903]

SUPERFERTIX .. would you care to elaborate whats inaccurate in this talk, or are you an expert just in passing judgments...?

[@stover954rr]

Yes, elaboration would be nice. I would assume the comment is referring to the car producing 150k newtons of force. In order for the calculations to work you would need to look at down force not total force. which would only be a fraction of the 150k.

[@Tadesan]

This person is not familiar with thermodynamics​. systems like this would simply be diverting energy from some other system; with an enormous efficiency penalty. your car would burn more fuel. walking would be more fatiguing.

[@vijayrajendran5301]

Why do you say so? The same distance will be travelled!

[@nneerraajj2903]

Tadesan .. why would the car burn more fuel..? it would just run like it does, and the pressure on the road would generate power, isn't it better to get some electricity from cars and walking, than getting none...?

[@julduc6113]

Tadesan, please could you explain why? I am really interested to understand your point of view.

[@undernetjack]

I think using piezo under the carpet, for example, will take a fraction more of your walking energy to activate the effect. Putting it another way, it would more exhausting to walk on sand or gravel as opposed to just compacted earth or concrete. Taking this further, your car would use more gas or electricity on the piezo road as opposed to a normal road. The thermodynamics comment above means the use of piezo in these types of applications would only work by causing the system to use additional energy to feed the piezo. You would not get back any extra energy unless you paid for it with extra effort or petrol. Not to say there aren't applications where this might work, just not the ones mentioned. You could set up piezo to use wind power or sunlight or ocean waves.....but then there are probably more efficient means of harnessing those. Now, some sort of nano piezo on a large scale, utilizing graphene and carbon nano tubes to capture Casimir effect energy .....or even cosmic microwave radiation? That would really tap the keg.....

[@julduc6113]

Thank you very much for your reply! Very interesting ;-)
