Elizabeth Redmond of POWERLeap on piezo power for large cities

[arunkumar8619]

I want to do this as a project for my academic... Any inputs please..?

Just put them under roads, where you have variable loads all day long. Not so good at night...

Or maybe under a shoreline where the lapping waves make energy consistently.

I shall like I shall assure distribution in France That it is the address of the purveyor.

I have a guestion, what's a ballpark figure for the ammount of energy produced in one step on one tile? I'm talking joules, and at what voltage.

If they can create double digit joules from each step they could be interresting. The power to light the leds in the board doesn't have to be more than a watt or two (watt = joule*second), so them lighting up doesn't proove much more than there actually being currents induced.

@gulllars watt = joule / second

I also wonder about the hidden energy loss. What I mean is, think about walking on a beach. It's very tiring to walk on a surface that isn't completely solid. I notice those plates move slightly. I wonder if you'd be worn out quicker if every step you took wasn't on completely solid ground.

[gulllars]

@rexroof The ting making you tired from walking on the beach is your footsteps deforming the sand. These plates move a few millimeters (fractions of an inch) and the surface does not deform, so it will basically be like walking on a hard surface at 0,1 degree upphill, or lifting your foot a tiny bit higher with each step.

Wouldn't those things wear out over time? Then the cost of replacing them probably wouldn't be worth the energy produced.
