You lost me on the noises, what noises?

But my idea is avoiding the casimir effect and focusing on piezoelectrics tuned into the Schumann frequency, or maybe turned to various noises.
It says this "explains why rock and roll wouldn’t power your home", inferring that instead of random sound, it uses sound apparently in a narrow frequency range which would be easier to convert to energy. Other than the conservation of energy concept which explains theoretically how heat can conceivably be converted to sound energy which can in turn be converted to electrical energy, I can't say I fully understand this concept.
It works via a very simple and well known process. If you take a source of heat and apply to any enclosed area, the air inside it will expand increasing the pressure inside. This pressurized air will then move through a filter or opening on one side, producing a simple clear sound at a standard frequency. That’s the key to the system. The more focused and directed the frequency is, the easier it is to extract energy from (which explains why rock and roll wouldn’t power your home, though it made for a nice intro). The sound waves then pass through “piezoelectric” devices which transform the sound into electricity when squeezed by sound.
We already have very common micro oscillating devices, like the one that regulates the frequency in the computer or phone you're using to post in this forum. A battery applies a voltage to a quartz crystal and yes it can oscillate but it consumes energy, it doesn't release energy (this is why digital watches need batteries, but they can last many years so it doesn't take much to excite the oscillator).

These papers below indicate to me that not only can we use
the Casimir effect to create an oscillative driver system (much
like an audio speaker system can vibrate glass), we can use the
same effect to create quantum antennae systems for micro-chip
scale communications systems (i.e. REALLY CHEAP ultra-small
onboard cell phones and Ethernet-style network chips on CPU chips!)...
The oscillation in this experiment requires power input, just like the digital watch oscillator.
We excite the torsional mode of oscillation by applying a driving voltage
The Casimir effect, for example, is the attractive pressure between two flat parallel plates of solids that arises from quantum fluctuations in the ground state of the electromagnetic field. The magnitude of this pressure varies as the inverse fourth power of the separation between the plates
So, you'd need to extract 100% of the vacuum energy from about 57.4 trillion olympic pool volumes per day to power the average home....
It just doesn't sound very practical to me even if we could extract energy from the vacuum, which I suspect we probably can't.
Now compare this with solar power for example. if you adjust the figures in this source for the average power of 1020 watts, then you'd need 44 square meters of solar panels to power the average home.
There's energy to be harnessed from the Casimir effect just as there's energy to be harnessed from gravity acting on falling mass. But once the water falls through the hydroelectric dam and generates electricity, the cycle is over, unless you can find a way to get the water back above the dam, which the sun does for us via evaporation and condensation.

That sort of available resultant energy is CERTAINLY ENOUGH to be
harnessed as an oscillative event cycle (i.e. mechanical vibration
into an electrical current) !!!
