Power walking: Turn each step into clean energy

Like body fat, stored energy has a habit of being always in the wrong place, and hard to use it. Large populations tend to concentrate in energy-deprived areas like South Asia, while energy sources pile up in sparsely populated areas like Central Asia in the form of fossil fuels.

An average person consumes or burns about 2,000 calories a day, which is basically about or about 97.2 watts at any sec. We consume more calories when we’re active, and less when we sleep.

Since we produce energy ourselves, wouldn’t it be great if we could use that energy, for instance, to charge our smartphones? An iPhone charger is only about 5 watts.

At the Astana Expo in July 2017, I saw an interesting piece of technology that could convert each footstep to about 5 watts. So, if there are 1,000 people in a mall, and 10% of them are moving at any given time, we could produce 500 watts, enough to light up 100 LED bulbs. 

Should not every public place use this technology? Watch the above video to find out more.
