Ya, this can be a good substitute that can have sufficient amount of electricity that can atleast make street lights work. ...... Since the devices are embedded 30 cm apart from each other and in two rows per lane, a kilometer of a two-way street will contain 13,333 devices, each device costing $30.39, adding to a total of $405,253. It will be so much expensive to have that implantation. For 1km it costs nearly Rs. 3,34,33,372.5 And another thing is to maintain its efficiency. So, at present, in my perspective this can't be implanted in INDIA. But Ya, in the upcoming years, as the technology develops, it will reduce its expenses. At that time we can have a good project upon it! ☺ Good Explanation ! It was informative. Keep working hard !
Hello, This is Naveen, i did my Engineering in Electricals now Iam doing research in piezoelectric, can you give me some basic ideas on how to start the work please.
Thank you for this example, which I can show a friend of mine, about nonsense research in the world. Basic physics tells us that with converting one kind of energy to the other, there are always losses involved. I find it nice how you try to sell this as "free energy" while in fact the idea comes down to cars constantly "driving uphill". Therefore, more chemical energy is required in the form of fuel to have cars drive over such roads, thus resulting in more CO2 emissions. Knowing that the efficiencies of: Fossil powerplants are 33% to 45% (Fuel --> Heat --> Kinetic energy --> Electrical energy) Gassoline cars are about 29% and Diesel cars are about 32% (Fuel --> Heat --> Kinetic energy) Then using the kinetic energy of cars to generate electrical energy results in a total efficiency of Kinetic energy --> Electrical Energy) I rest my case.
It's very normal for a road to experience vibrations when cars and heavy vehicles pass by. Piezoelectric roads recover this energy that would have gone to waste. There will be no or very minimal energy consumption by the cars. The roads are always busy now a days and no one is going to stop using cars in near future. The energy exchanged with the road by friction isn’t enormous. As you said losses will be more. But if you can capture just a fraction of it into usable electricity, the savings could be huge when you factor in tens of thousands of vehicles driving over a road on a daily basis. I don’t think this piezo electric road can replace conventional thermal power plants. I agree that efficiency will be low. But when the energy transition takes place, piezoelectric roads could be helpful as they can generate some decent amount of electricity.
Dude... Your statement about what basic physics tells us that converting one form of energy into a other incurs loss is wrong. :P There are many ways to categorize energy. In thermodynamics One way is to categorize energy is: high grade energy and low grade energy. When you convert low grade energy into high grade energy there are always losses involved. That's why you can't convert 100% heat into 100% electricity. That's why even in ideal case of carnot engine, you can't have efficiency more than carnot efficiency. But conversion of high grade energy into low grade energy can be 100%. So you're able to convert all of your electricity into heat. Without any loss. For example electric geysers. And here in piezoelectric roads, we aren't generating energy at the expense of fuel that's burnt in engine. We're converting mechanical stress into electricity. So the roads could be normal. Yes the construction would be a little difficult and costly but ultimately the roads gonna look normal after completion as they look now.
ITS GOOD TO SEE STUDENTS MAKING SUCH GOOD VIDEOES ON SUCH INNOVATIVE TOPICS.
Thanks to information I'll research the piezoelectric effect on do life it's very use for myself.
Thank you

Your voice are nice😄
Do you have any installer company
We are interested to install in our country
Nice concept
It is great to hear you feel that way!
