Global warming is one of the biggest growing problems that ruin the environment and our nature, which leads to general endangering and problems that are caused by chain reactions. Luckily, we have found the solution in terms of green technologies that replace the traditional harmful and toxic processes. Every day, the top-notch engineers and scientists work on the new plans and implementations of green technologies.

While green technologies seem like a leap in the future, these are not too far from us as we can find a lot of new examples throughout the world. The environmental-friendly processes that replace the traditional ones will need more time to replace them fully, however, there are several examples. With the technology advancements, we can expect that the number of these eco-friendly technologies rises in the upcoming decades.

The Green Technologies Aren’t Just the Future — They are Also Present

The constant work on the green technologies, by the company under the name Tecam Group, brings new improvements, which will help in achieving even higher thermal efficiency that will not contain any of the waste. The group is slowly taking over the majority of the industries with their patent as heavy industries like petrochemical, automotive and pharmaceutical conduct chemical processes that release toxic emissions in the air. Therefore, they will experience the implementations first-hand.

One of the best things that we can see in terms of green technology is the use customized systems as each company has unique settings and operational procedures. The Volatile Organic Compounds (VOC) emission is one of the best examples of how we can save our nature — during the industrial production processes, carbon dioxide is emitted, which ruins the atmosphere’s structure. Using the specialized exhaust air systems and improved combustion chambers, around 99.8% of the emissions are destructed, while 99.99% of the air within the chamber is held inside.

Waste-to-Energy is a form of green technology where you turn the waste into usable energy, usually with the help of steam, hot water or electricity. The sludge, as well as liquid waste, poses one of the biggest threats to our world and the scientists decided to battle this problem efficiently via incineration technology that uses chemical waste, natural radioactive waste as well as medical waste and turn it into energy/electricity that we can use further for powering other plants. The incinerators are the best solutions for waste management as these burn all the waste, instead of accumulating it in the soul before it starts evaporating or damaging the soil.

One of the latest uses of this technology is the energy of waves, where a coastal country may use the ocean’s waves for electricity production, through the installation of the floating tubes called Pelamis. An average plant that produces electricity using this technology is able to pull out around 2.25 MW of electricity, which is enough for 1500 houses! As you can see in the infographic below, Portugal had a huge problem with the man-made volatile missions, not to mention industrial emissions, but eventually managed to decrease it significantly in 2008 once the wave-conversion-to-electricity has been built.

The auto industry has seen a lot of changes, though these changes have not been adapted all over the world. Electric cars or vehicles that don’t emit any gases are the latest promise of green technology where the auto industry wants to protect our environment by eliminating gas emissions. China and the USA the leading world countries where electric cars are sold and we can expect that the electric cars sale is going to increase in the upcoming years.

The use of solar energy systems has been implementing all over the world, especially in countries where you have a lot of sunny days. The use of conversion technology through high vacuum tubes with hot water, polypropylene collectors and photovoltaic collectors that produce electricity created solar lights, energy generators and many other things where the accent is on the decrease of hydrocarbon and fossil fuel dependence. Therefore, solar energy is taking over the standard electricity in some rural areas of countries but we will have to wait a bit more to get this on the commercial level.

Solar Energy Improvements and Inventions

So, how does solar energy system work? The solar panel, which consists of silicon cells that form a solar cell, can output the voltage and therefore create the electricity where the more cells you have, the higher wattage you can achieve. The panels are placed in direct sunlight to collect sun energy, which is transformed into electricity.

Being easy to use and implement, solar energy is one of the most sustainable sources of energy, which was enough for creating things like portable solar kitchens, solar backpacks, solar AC systems and many other things. One of the best inventions is the solar outlet that stores energy for use while absorbing solar radiation. Once it is fully charged, you can take it with you and connect your phone charger and charge your phone!

Thanks to the sustainability and easy implementation of solar technology, the use of solar systems have been increased significantly in the past 10 years. In 2000, the entire solar system energy production in the whole world barely exceeded 1 terawatt-hour, while 20 years later this number increased over 600 terawatt-hours, which is stunning 41%! The statistics that we see tell us that we can expect even bigger growth as more and more countries experiment with solar energy improvements.

Wind Energy Innovations

The wind energy innovations have not been lacking at all as there are a lot of new inventions in this field and we would like to mention quiet wind turbines that you cannot hear at all while working! The Australian Renewable Energy Solutions developed a quiet wind-turbine that can generate up to 20 kW of energy in a more efficient way. The model is still in the experimental phase, but it has been online for a couple of years now.

Another invention are low-speed wind turbines that work similarly to the horizontal aerofoils that are used on airplanes. These do not produce any kind of noise while working while using low-speed wind for electricity production. It means that it can be easily integrated into the existing systems, which reduced the cost of installment drastically. What is even better — these can be set to work on higher-speed winds as well, making them multipurpose.

The amount of wind energy patents and inventions is going to increase and we can expect to see a lot of new things that will contribute to the overall wind-energy production in the world. At the moment, the US is the leading country when it comes to wind energy and the below infographic shows the wind-energy consumption in the US since 1990. The experts predict that a good portion of the worldwide countries will start implementing wind-production plants that will convert the wind energy to electricity.

Life is Water

Our adult bodies contain up to 60% of the water in the entire weight, which says enough about the fact that there is no life without water. Thanks to green technologies, we will be able to save our water flows and prevent pollution that might destroy the entire eco-system that lives in/under water. Water reuse will become one of the most important aspects as some scientists predict that there will be a water shortage at some point of time in our history.

The conventional technologies for water treatment can help in this process, but the main problem is that such technologies produce side products and emissions that harm the environment and air. One good technology for wastewater management is a wetland, which can be made naturally or artificially. The main goal of the wetland is to release oxygen into the air to enrich our atmosphere and make it more suitable for our lives.

The increase of wetlands contributes to the entire environment and this has been seen in Jamaica. This country had 14.2 hectares of wetland in 2010, while this number is at 15.3 at the moment. The efficiency of the wetlands is seen in the structure of the atmosphere — the more water you have, the better life conditions you can achieve and therefore we can confirm that life is water!

The Future of Oil Fuel 6 — How the Artificial Meat is Grown?

Besides the classic use of sun, wind and water, there is also the use of oil as a substance for electricity production. Oil Fuel 6 is a small fraction that is made during the process of petroleum distillation and it consists of alkanes, cycloalkanes and aromatics compounds. While this oil can be used for electricity production, it is not recommended as it emits pollutants during the combustion process and therefore likely won’t be used as the derivate for electricity production in the future times.

Another thing that might have the future is the artificial meat that is grown without any harm to the environment (as you know, cattle is one of the biggest environmental enemies due to greenhouse gas emissions). However, this type of meat also has some side effects that might harm our environment, but not as near as the cattle has and therefore it can be future meat for our people. By using the artificial meat, the cattle will cease to exist at some point in time and therefore the harm to the environment will be reduced to the minimum. In addition, the flavor will be perfect, so everyone will probably forget the regular meat that we get from the cattle!
