Video summary
The video explores the innovative concept of generating electricity from everyday movements within a home using kinetic floor tiles known as PISO. These specialized tiles are designed to convert the force exerted by footsteps into usable electrical power, with each step capable of producing approximately 7 watts of energy. The underlying mechanism involves the deformation of the tile's material when stepped upon, which separates electrical charges and generates an electric current that is subsequently stored in a battery for use by low-power devices such as lights, sensors, and charging equipment.
To illustrate the potential impact of this technology, the transcript calculates the total daily energy generation based on average household activity. Assuming an average person takes about 11,800 steps per day, and each step yields 7 joules of energy (derived from the power output over a one-second interval), a single home could theoretically generate around 82,600 joules daily. This accumulated energy is sufficient to power essential household electronics and contribute to sustainability efforts by reducing reliance on external power sources for small-scale devices.
While the energy savings achieved by installing these tiles in an individual residence may appear modest at first glance, the video emphasizes that the true value lies in widespread adoption. If millions of households were to utilize PISO electric tiles across their floors, the collective kinetic energy from billions of daily steps could result in a significant reduction in overall energy consumption. This scalability transforms what seems like a minor technological advancement into a powerful tool for environmental sustainability, demonstrating how converting simple human motion into electricity can make a substantial difference on a global scale.

What if every step in your home could
generate electricity? I used a data
logger to measure my footsteps in
Newtons. According to the National
Energy Foundation, kinetic tiles can
convert this force into 7 W of power per
step. The movement causes kinetic
energy. This is converted into
electricity through the piso electric
tiles on the floor. Stepping on the piso
electric tile deforms its material,
separating electrical charges and
producing an electrical current. And
that is how the energy is converted into
electricity. This electricity is stored
in a battery and is used for low power
devices. The energy in one step equals
power * time. And if power equals 7 W
and time equals 1 second, that means the
energy per step equals 7 JW. On average,
there are 11,800 steps per household per
day. And if we multiply that by 7 jewles
per step, then we will get 82,600
jewels. This energy can power lights,
sensors, and charging devices.

Individually, the energy saving from
using piso electric tiles is small, but
if used in millions of homes, this could
make a real difference for
sustainability.
