How To Generate Free Electricity - Science Experiment With Vinegar And R... 

Today we have a very simple and fun science experiment to try at home. We all have seen videos or science experiments of lighting our LED lights from lemons or potatoes. Today, in our science experiment we would use vinegar and 5 Rs coin to generate electricity and light our LED bulb.

In this science experiment, we explore the principles of electrochemistry and generate free electricity to light an LED bulb using coins and small cardboard pieces soaked in vinegar. The materials needed include several coins (preferably copper and zinc), cardboard pieces, vinegar, an LED light bulb, and wires.

First, prepare the cardboard pieces by cutting them into circles slightly smaller than the coins. Soak these cardboard pieces in vinegar for about 10 minutes. The vinegar acts as an electrolyte, facilitating the flow of electric current.

Next, assemble the voltaic pile. Begin by placing a copper coin (or any coin with a significant copper content) on a flat surface. Place a vinegar-soaked cardboard piece on top of the copper coin, followed by a zinc coin (or any coin with significant zinc content). Repeat this stacking process until you have a pile consisting of several such layers, always ensuring that the final layer is a zinc coin.

Once the voltaic pile is constructed, attach one wire to the topmost zinc coin and another wire to the bottommost copper coin. Connect these wires to the LED bulb. The chemical reaction between the vinegar-soaked cardboard and the coins creates an electric current, which flows through the wires and powers the LED bulb.

If someone suddenly asks you, how much electricity can a photovoltaic panel generate in a year? Probably many people will be stunned, yes, how much? This involves two determinants of photovoltaic power generation:

First, the power generation of photovoltaic panels.

Second, the installation area of photovoltaic panels.

In the same area, the higher the power generation of photovoltaic panels, the shorter the time it takes to generate 1 kWh of electricity, and the higher the power generation in one day.

Photovoltaic panels generate electricity only when there is sunlight. Therefore, the electricity cannot be generated at night. Similarly, in strong winds, smog, rain and snow, it is almost impossible to generate electricity. That is to say, photovoltaic power generation is closely related to the installation area. Different resource areas, the same type of photovoltaic panels, will also generate different amounts of electricity. In some places, there is enough light, which is inherently advantageous.

Calculate an average value, a photovoltaic panel can generate almost 400 degrees (theoretical value) electricity a year.

Why is it a theoretical value? This is because, in addition to the power generation of photovoltaic panels and the installation area (annual equivalent utilization hours), photovoltaic power generation is also restricted by external factors, such as installation angle and orientation, local climate, Connection line material, surface cover, etc.

Installing photovoltaic panels requires an installation angle and orientation so that the photovoltaic panels can fully receive sunlight and perform their best functions. If you install it indiscriminately, people have an angle, you lay it flat; people sit north to south, but you sit south to north, which is contrary to science, but it will affect the power generation!

Days of rain, snow, haze for a long time, sandstorms, etc., even the sun can't be seen, and even the best photovoltaic panels can't generate electricity.

If you use low-quality cables and other lines, the electricity will be secretly leaked, and it will be useless to send more and more accidents will occur. This shows the importance of material.

The shielding of photovoltaic panels should be cleaned from time to time. For example, if there is a big tree near the photovoltaic panel, or a tall house, and the total light is not enough for a few hours, how can it fully generate electricity. That's a question of location. Or, the local wind and sand are heavy, so they can only install photovoltaic panels, but they are not carefully maintained, and the panels are covered with dust and cannot fully generate electricity.

All of the above are factors that affect photovoltaic power generation, so if you want to generate more power, you have to maintain and care for it.

How Is Electricity Generated?

Have you ever imagined what would be the world like without electricity? Oh, it is quite horrible. What if the imagination becomes real? Thus, to save you from any daunting situation below, we are discussing everything you should know about electricity generation.  In 1600 William Gilbert coined the term electricity from the Greek word “electron”.He surely didn’t know about its importance.…

With water encompassing over 70 percent of the Earth, it would make sense to try and gain alternative energy from the ocean. Ocean Thermal Energy Conversion or OTEC is a way to do just that. In other words, the different temperatures of the ocean in deep and shallow waters will be able to run a heat engine, which runs efficiently with great temperature changes.

There are three states that are heavily involved in exploring OTEC. The United States is one of them and has a large OTEC facility in Lancaster, Pennsylvania. Tests are done here to learn more about the technology. It has been said to be the perfect place for OTEC because of the warm surface temperature and access to deep cold temperatures of the ocean. Japan, while not a great area for OTEC, created a closed-cycle OTEC plant on the island of Nauru. It uses the energy to power the plant and neighboring communities. India also sponsors OTEC operations and is looking for ways to get new and better energy.

There are three ways to use OTEC: open cycle, closed cycle and hybrid cycle. Of the three cycles there are also three locations, land-based, shelf-based and floating-based.

A closed-cycle system uses a fluid with a low boiling point to go around a turbine. Warm surface ocean water is pumped in causing the fluid to fade away and the vapor turns the producer. Cold ocean water is pumped through the other side, causing the substance to form back into liquid and start the cycle all over again.

An open-cycle uses the ocean's warm surface temperature to make energy. Warm seawater boils when placed in a low-pressure container. The steam turns the low-pressure turbine, which in turns moves the generator. It is condensed back into liquid form when it comes in contact with cold hotness from the cold seawater.

A hybrid-cycle contains features of both systems. In the hybrid system, warm water is flash vaporized causing the steam to vaporize the low-boiling point fluid. The vapors drive the turbine and the steam condenses with the cold temperature creating desalinated water.

While it sounds like a great plan and a wonderful way to use the environment in a safe manner, the problem is this technology is extremely expensive. The United States hasn't run any new tests in almost 10 years because of the costs, especially with companies focusing on other energy sources. Few other countries have been working at ways to find an operational system. The reason why it is so expensive is because the main thing needed is a large pipe, sometimes a mile long to reach to the bottom of the ocean to get the cold water. Creating this pipe and maintaining the process costs too great of a price.

However one of the huge advantages to OTEC is that it provides more than just electricity. By bringing up the cold water from the bottom of the ocean, there are many other uses such as air conditioning, chill-soiled agriculture, desalination and mineral extractions. But there are concerns worldwide about the effects of using alternative energy from the ocean can cause on the environment. Unfortunately, because of the lack of research this question may never get answered.
