Ice ice baby!!

[BK911]

Who wudda thunk.
Fascinating.

It would bee cool (pun intended) if we can generate usable electricity for homes with it. I ain't gonna hold my breath. It might make a few milivolts but nothing to run a car or my computer.

When I saw the title, I thought this was a thread that was going to PARF before the end of the day.

Love me some vanilla ice!!!
Don't have his moves, or his hair, but I did drive this to work today:

As did I.

[oldE]

So for example when massive glaciers calve as the result of flexing of centuries of built up ice reaching the sea we might be able to harvest perhaps a picovolt or two?
A curiosity.

[BK911]

So few things to consider...
This technology will only get better.
New materials will be created to emulate ice, but with better flexoelectric properties.
New materials will require less energy to perform.

Fascinating.

how does one design current collectors to harvest said electricity?

Not just a few mV, a few FREE mV.
Sprinkle in some geometric amplifiers and resonance frequency and we start cooking!!

Not just earth, but imagine harvesting energy from frozen planets and moons throughout the cosmos.

Free? How much energy is expended to bend the ice to induce the reaction?

[unclebilly]

How do you collect the electrons in a meaningful way? Seems to me that ice doesn’t conduct electricity (salt water conducts ions)… do you have to suspend metal in the water some how and then freeze it?

I think it would be easier to harvest lightening.

Piezoelectric materials don’t require energy to keep them frozen.

In general the concept of getting energy from bending an object seems to have limited uses. Why not just use the energy that you were going to use to bend the object?

[BK911]

Maybe the object bends naturally, tides, gravity, temp difference, ???

Just off the top of my head....
I'd probably build some large pyramid shaped structures that would collect the small bits of energy, and amplify it as reached the tip. Maybe build out of something with high piezoelectric properties such as granite, then cover with insulating limestone.

Crazy, ehh?

But where would you source the thousands of gallons of mercury to fill the pools beneath those structures?

ALL forms of energy production or energy conversion to usable energy creates heat. Using the bending energy directly sounds more logical.

[QUOTE=BK911;12534555]Maybe the object bends naturally, tides, gravity, temp difference, ???[

But is the object that is naturally bending also piezoelectric . . . if the ocean or trees were piezoelectric, that would be convenient.

If we have to attach a device to a naturally bending object, there’s probably better ways to generate energy from the bending - or the force producing the bending - than piezoelectric.

Generating electricity from tidal forces, for example. Wind turbines are way more effective than using piezoelectric on trees. Etc.

[unclebilly]

Tides and currents are predictable, unlike wind. Water has 1000x the energy density of water moving at the same velocity.
