10 environmental technologies of the future

Using electronic paper, solar power, hydrogen technology . are the outstanding environmental technologies in today's era - with pollution and exhaustion of resources.

Policies that use energy full of waste, abuse of resources, lack of water supply, global climate change, deforestation . are some important topics that experts need to pay attention to. to help people create a sustainable life on this planet.

According to the United Nations forecast, by 2025, the population will increase by 2.9 billion people, will exhaust the depleted water and the world's energy demand will increase by 60% by 2030.

However, according to experts, people can expect positive improvements from the adoption of the following environmental technologies that can contribute to a much brighter future.

Limit using paper

Imagine lying on the lounge chair with the morning newspaper, then, with the same page, you used to read the latest novel of your favorite author.

You will only have to bring a single newspaper.

It is an ability of electronic paper, a kind of flexible screen like traditional newspaper but can be reused continuously. Its screen consists of countless microcapsules containing charged molecules.

Each nanoparticle contains white and black molecules with negative and positive charges. Depending on the electrical signal, black and white molecules create different surface layers.

Try to do simple calculations, every day more than 55 million newspapers are sold, if using the above electronic newspaper, it will save a large amount of forest trees for pulp.

Bury exhaust gas into the ground

CO2 is the main waste gas causing the greenhouse effect, causing global warming. According to the Energy Information Administration, by 2030, people will emit nearly 8,000 million tons of CO2.

CO2 will be separated and processed from the source of emission.

Many experts say that it is impossible to prevent CO ₂ emissions into the atmosphere but only ways, we must find ways to treat this gas. One method is to pump CO2 into the ground before it has a chance to emit into the atmosphere.

After separating CO ₂ from other emission gases, it is buried under oil wells, salt ore and exploited rock seams.

Although this sounds great, scientists are not sure if the pumped gas is permanently stored, how long-term the impact is and the cost of gas separation and disposal. It is quite high to consider this technology a short-term practical solution.

Use plants and bacteria

Biological therapy industry uses bacteria and plants to treat pollution. Many experiments such as nitrate treatment in water contaminated with bacteria, using plants to clean soil contaminated with arsenic.

Huge future of plant use in environmental pollution treatment.

The US Environmental Protection Agency has applied biological methods to clean up some contaminated areas in this way. Currently, scientists try to breed new plants capable of transferring pollutants from the roots to the outside through leaves.

Planting trees on the roof

This concept has existed since ancient times, typically Babilon Hanging Gardens, one of the seven wonders of the ancient world. Legend has it that the rooftops, balconies, and terraces of Babylon royal palace must become the king's garden of love to show love to his wife.

Green roofs help greatly reduce the temperature of your home.

From a modern environmental point of view, the roof garden will help absorb heat, reduce the impact of CO2 by absorbing CO ₂ and emitting O ₂ , cooling the air to reduce the power used for air conditioning.

In a nutshell, this method will help reduce the 'Heat Island' effect commonly found in city centers, and know, butterflies and birds also visit the roof gardens, and Help us get more excited every day.

Exploiting waves and tides to generate electricity

The ocean accounts for 70% of the earth's surface area. Ocean waves are an abundant source of energy that can turn turbines to generate electricity. The obstacle to using this energy source is its exploitation. Sometimes the waves are too small to provide enough power for the generator.

The potential of hydraulic energy is abundant.

However, the remedy is to store energy when the transmitter has enough energy to operate. The East River Company in New York is currently testing a six-turbine power generator system.

Currently, engineers study a system capable of harnessing energy in remote areas.

Ocean thermal energy metabolism (OTEC)

The largest solar panel on Earth is the ocean surface. According to the US Department of Energy, every day the ocean absorbs heat from the sun equivalent to the thermal energy of 250 million barrels of oil.

Prospects from OTEC technology will bring significant energy.

Currently, OTEC technology converts the heat energy contained in the ocean into electricity by taking advantage of the temperature difference between the sea surface (hot) and the sea floor (cold).

The temperature difference can turn the turbine to generate electricity. The drawback of this method is that it is still not effective enough to be the main mechanism for energy production.

Use of solar energy

Solar energy, which reaches the surface of the earth in the form of photons, can be converted into heat or electricity. There are many types of solar collectors that have come into being and have been successfully applied by many energy companies and individuals.

The power gained from the Sun is always endless.

Solar collectors have two common forms: solar batteries and solar thermal applicators. But researchers have found a more efficient way to convert this abundant energy source using mirrors and parabolic troughs to converge solar energy.

Part of the challenge of using solar energy is motivation and encouragement from the government. Pioneering in the application of this modern technology is an energy company in Spain, which has just opened a solar thermal power plant to provide enough electricity for 6,000 households and help reduce 18,000 tons of gas. CO2 / year.

Hydro power

The use of hydrogen fuel cells is considered an unpolluted alternative to fossil fuels. Instead of emitting smoke that pollutes the environment, hydrogen fuel cells produce a byproduct of water due to the combination of hydrogen and oxygen in the process of generating electricity.

Cars using Hydro engines are an option for the future.

The problem with fuel cells is how to obtain hydrogen. Water and alcohol molecules must be treated to separate the hydrogen supplied to the fuel cell. Recently, scientists have found a way to supply energy used for laptops and other small devices with fuel cells.

Many automakers promise to create a new generation of cars with the only waste being water. The promise of an unknown economy will soon come true.

Desalination in sea water

According to the United Nations, by the middle of this century, the depleted water will affect billions of people around the world. Desalination basically removes salt and minerals from seawater, which is a feasible method to supply water to many parts of the world, where drinking water is lacking.

Despite the high cost, this technology will be a future for water resources on Earth.

The drawback of this technology is that the cost is too high and it consumes a lot of energy. Scientists are working on a better process, to use cheaper fuels to heat and evaporate water before letting it flow through thin membranes to increase efficiency.

Oil production from anything

In principle, any waste of carbon components - from chicken manure to old tires, bottles - can turn into petroleum if handled by the so-called thermo - depolymerization method, similar to producing oil from nature. Proponents of this technology claim that 1 ton of chicken waste can produce 600 pounds (about 273 kg) of oil.

But to have the same product, it took millions of years. If you want fast, scientists have to study the machines that create the environment with the right temperature and pressure. This requires a small cost for research and operation. Therefore, the production of artificial fossil fuels may temporarily meet demand during the transition period, not a long-term solution.
