As I wondered people walk daily approx 2km .
And each step is a form of force applied to ground
I got an idea by lighting up the gas stove by a lighter.
Just by pressing with a thumb it generates energy.
I have questions like can we store this energy?
So by applying force by a footstep some amount of lighter it can generate good amount of energy.
These lighter works on piezoelectric material which get hammered and these material release energy( please correct me if iam worng)
This kind of generator is already being tested in other parts of the world. Pavement tiles are the application I have seen most often publicised.
Correct. But the force applied is quite large and rapid. Rapid release of energy from the spring stored into the spring by a long press of the hand.
There already exist devices that use piezo elemnts to harvest energy. On large scale from waves and on smaller scale by body movement.
However Tribo Electric Nano Generators TENG are the new rage. RF-TENG being the latest and greatest - wireless charging of cell phones by walking.

So why it is not practiced in our nation
Can we make it in lab as DIY and harvest energy in small scale.
Yes, we can make such devices. Although without precision equipment our effeciency will be substantially lower than state of the art techniqes.
I don’t know the answer.
Clearly, some tech company needs to feel the risk of developing an affordable product is manageable. And installation with harvesting, in any public place, means most likely that some public body, such as a municipality or state electricity distributor, must also be involved.
The alternative, and probably more doable, is for the entrepreneur to target industrial campuses, and campuses of large private educational institutions.
A possibly related effect has been observed (link needed), where the rapid detachment of sticky tape from a surface generates X rays. In this reference (it was also reported in New Scientist, and has been known for some 50 years) Peeling Sticky Tape Produces X-rays | IFLScience the researchers were able to use the phenomenon to obtain a scan of a finger.
