A power-packed stroll in the park can provide enough energy to charge our MP3 player, laptop or phone for hours on end. In these power shoes, you are capable of losing around 10W of power as heat each time you complete a single step. Since, laptops and phones require energy between 1-15W, therefore the power produced by our gait
The technology could enable a footwear-embedded energy harvester that captures energy produced by humans during walking and stores it for later use. Power-generating shoes could be especially useful for the military, as soldiers currently carry heavy batteries to power their radios, GPS units and night-vision goggles in the field.

The G7 also committed to a quantitative global goal to increase energy storage in the power sector to 1500 GW in 2030—a more than six-fold increase from 230 GW in 2022. This major commitment will advance the COP28 global goal to triple renewable energy capacity by 2030 and transform intermittent energy into reliable baseload power.
Step 1: Materials. First of all, you obviously need a shoe. I suggest getting a shoe with the thickest sole available because you''ll need to put stuff inside. Next, you''ll need two rechargeable flashlights for their generators. The two pictured below are the two I used and the next picture is one of their generators.
