How much power does an energy harvesting paver produce?

Experiments are carried out to verify the dynamic model. The experimental results match well with numerical simulations. The experimental results show that the energy harvesting paver can produce an average power output of 3.6 W over 0.5 s of step time, with a peak power of 12 W. The output electrical energy is 1.8 J per step.

What are the numerical simulation results of the energy harvesting paver?

Numerical simulation results of the energy harvesting paver: (a) top panel displacement; (b) generator rotational angular velocity; (c) power output. All system parameters are from the energy harvester prototype. 10 Ω load resistor is used in the simulation.

What technology is used to harvest energy from the pavement?

Currently, two main technology groups are being utilized to harvest energy from the pavement: (a) those based on solar radiation, or heat; and (b) those based on converting the kinetic energy from the moving traffic to electric energy. Both of these sources have shown potential to supply energy to the transportation infrastructure.

Can energy harvesting paver power a torch light?

In order to verify the output power of the energy harvesting paver, we tested it using an Ozark Trail 500-Lumen Spotlight. It turns out that the harvested energy is enough to power the torch light at its specified conditions.

How much energy does PaveGen generate?

When located in a busy street, each slab generates 2.1 watts per hour. Studies have shown that during peak time of five hours, Pavegen generates enough energy to power a bus stop for 12 hours. Energy can then be stored within the pavers’ lithium polymer batteries or sent back into the energy grid.

How is energy harvesting a paver calculated?

The mechanical energy input to the energy harvesting paver is calculated by the enclosed area of the force-displacement loop. As the equivalent inertia increases, the mechanical energy input increases. The increase rate slows down and eventually reaches a maximum value, i.e. the potential energy.
