Good day everyone,
Today, I want to talk about a form of energy harvesting that you may not have heard much about: capacitive coupling. Typically, when we discuss energy harvesting, we talk about inductive methods such as RF and power lines. However, capacitive coupling can be just as effective.
Before we dive into the specifics, let's talk about what capacitive coupling is. In short, it is a method of transferring energy from one object to another without the use of wires. It relies on the concept of capacitance, which is the ability of two objects to store an electrical charge.
Now, let's get into the nitty-gritty of how capacitive coupling works. To start, we need to calculate the capacitance of the system. This is dependent on the frequency, which in our case is 60 hertz (Hz) since we're dealing with power lines. Next, we need to figure out the capacitive reactance values, which is where things get a bit more complicated.
Assuming we're using a 25-foot strip plate of metal for the capacitive coupling, we can calculate the reactive capacitance to be 394.6 ohms. We also need to use Ohm's law to find the current value and power factor assuming we're receiving 50 volts of power to our system. Based on these calculations, we can estimate that we can receive a total of 6.33 watts of power output from the air through capacitive coupling.
Now, you might be wondering how this can be applied in real life. One potential use case is to build a conductive plate that acts as a capacitor and place it above the same length as a solar panel. Through wireless capacitive coupling, you can extract a significant amount of power that would otherwise go to waste. This power can be used to trigger circuits or charge batteries.
Of course, it's not as simple as just building a plate and calling it a day. We need to ensure that it's safe and efficient to use. Here's an example of how a system like this could be implemented:
Assuming we're roughly 75 feet away from a power line, we can place our 25-foot plate underneath it. One side of the plate should be grounded, and the other side should be connected to the capacitor. This will allow for the capacitive coupling of voltage between the plate and the power line.
One thing to note is that this method won't be as efficient as being directly plugged into the mains. However, it's still worth considering since it's essentially wasted energy in the near field. Any extra source of power we can use is better than nothing.
In conclusion, capacitive coupling is an often overlooked form of energy harvesting that has the potential to be just as effective as inductive methods. While it may seem complicated at first, it's a valuable tool that we can use to extract power from the air.

"Revolutionary Windows: Harnessing Thermal Energy for Winter Heat"
As the winter season sets in, heating costs can skyrocket, making it difficult for households to stay warm without breaking the bank. But what if there was a way to harness the power of thermal energy to keep your home warm? That's where revolutionary windows come in.
The concept behind these windows is simple yet innovative. One side of the window is designed to pull the cold air from the freezing outside, while the other side is designed to pull the heat from the inside. This thermal reaction creates or powers a heat source that can keep your home warm and cozy throughout the winter season.
To achieve this, the windows helps to transform the temperature difference into electrical energy. This electrical energy is then used to power a feedback loop between two coils, which increases the amplitude of the thermal reaction.
The result is a cost-effective and energy-efficient solution that can be used in homes, offices, and other buildings. By harnessing the power of thermal energy, these revolutionary windows can help to reduce heating costs and provide a more sustainable source of heat.
In addition to being a practical solution for winter heating, these windows also have the potential to be used in other applications. For example, they could be used in greenhouses or other agricultural settings to help regulate temperature and provide a more stable growing environment.
Overall, revolutionary windows represent an exciting development in the world of sustainable energy. With their ability to harness thermal energy for winter heat, they offer a unique and innovative solution that could have far-reaching implications for the future of energy production and consumption.
To take this concept a step further, solar power can also be incorporated into the design by using a solar diode as an oscillator instead of a traditional solar panel. This oscillator can also be used with two coils to create an additional feedback loop, which can increase output.
The combination of thermal and solar power in this way provides a sustainable and renewable source of energy, as well as a means of reducing energy costs and environmental impact. Additionally, this approach can provide an innovative and unique way to utilize windows in buildings, making them a source of green energy instead of simply a passive component of construction.
While this concept is still in the early stages of development, it holds great potential for providing an alternative energy source that is accessible, affordable, and environmentally friendly. With continued research and development, it may one day become a significant contributor to the world's energy supply, helping to mitigate climate change and reduce dependence on fossil fuels.
To construct your window, you could potentially use a thin film of bismuth telluride sandwiched between two layers of glass. The layer of bismuth telluride would be in contact with the outside air, while the layer of glass on the inside would be in contact with the warmer indoor air. As heat flows from the inside to the outside, the bismuth telluride layer would generate an electrical potential that could be used to power a heating element or to charge a battery for later use.
Of course, there would be many design considerations and challenges to overcome in creating a functional window like this, including the need to maintain a seal between the inside and outside environments, optimizing the materials used for maximum efficiency, and dealing with the variability of outdoor temperatures. But with careful planning and experimentation, it could be possible to create a window that helps regulate indoor temperatures using the power of thermoelectricity.
