It appears from the original text that a specific gadget may produce sound without using any energy.
That is not the situation, though.
The true source of the devices power is a nearby radio transmitter that emits waves.
The gadget detects these waves and uses them to power the crystal earphone.
Thus, although the apparatus appears to be producing sound on its own, it is actually obtaining the energy required from an external source.
Take a crystal set radio receiver, for instance in the below circuit diagram:
The conversion efficiency ratio COP expresses the systems output power in relation to the users input power.
Due to the fact that the user does not need to power the crystal radio, its COP is high.
The crystal radio can have a COP of more than 1, even if it does not use all of the power that it receives.
Effectiveness is a metric that quantifies the amount of input power utilized, with a maximum value of 100%.
Efficiency and COP are therefore not the same.
Take the solar panel as an illustration below:
It might first seem to be a free energy gadget since, when exposed to sunlight, it produces electricity for a load like a radio or fan ostensibly without any input from the user.
When the panel is utilized in the dark, however, this viewpoint completely shifts and makes the sun appear to be its energy source.
According to the Law of Conservation of Energy, the panel only produces power from around 17% of the solar energy it receives.
This concept only applies to closed systems, therefore if you take into consideration the incoming energy, it still remains true when there are external energy sources present, such as sunshine.
Confusion frequently arises from the concepts of efficiency and “over-unity.”
“Over-unity” indicates that a system generates more energy than it uses, which is not physically feasible because it calls for drawing more energy than is there.
Because practical systems always suffer some loss, their efficiency is by nature not 100%.
However, because they do not require the user to directly supply electricity, even seemingly inefficient equipment like solar panels which have an efficiency of about 17% can have an apparently limitless Coefficient of Performance COP.
This indicates that the output power is divided by the zero input power in the COP calculation, potentially yielding an infinite result.
Visible energy, sometimes called “Dark Matter” or “Dark Energy,” makes up about 80% of the material substance of the cosmos.
This energy is available everywhere, even though humans are unable to directly detect or quantify it because of its fast fluctuations and the absence of suitable measurement instruments.
Overcoming considerable technological obstacles is necessary to effectively utilize this ambient energy, just like a crystal radio set receives radio waves.
According to Zero-Point Energy theory, which describes the energy contained in every cubic centimeter of “empty” space, this energy may be used for commonplace purposes given the appropriate methodology.
Batteries and generators, for example, produce positive and negative charges that change the surrounding quantum foam and cause energy to flow from the environment, forming a “dipole”.
The battery drains as a result of the constant dipole reconstruction even if this energy does not originate from the battery itself.
In order to effectively utilize this energy, methods for drawing electricity from the environment without upsetting the energy balance must be discovered.
Although it is technically possible to harvest and use this free energy, there are a number of obstacles that restrict its practical usage, such as commercial and political obstruction.
Devices to capture this energy have been developed by several inventors, but commercial manufacturing is frequently hindered by interests seeking to control or limit these technologies.
Conclusion:
To conclude, although technologies such as solar panels and batteries may appear to defy energy conservation rules at first, they really function in accordance with these principles since they make use of external energy sources.
The idea of the Coefficient of Performance COP emphasizes that, even in situations when a device seems to be extremely efficient, it still obeys the rule when all of its energy inputs and outputs are taken into account.
Though there are many practical and political obstacles to overcome, the possibility of accessing enormous, invisible energy sources is still enticing.
Recognizing and conquering these obstacles may open up fresh avenues for utilizing plentiful but underused energy sources.
