There is an assumption of the skeptics that the technology is only harming the environment. This assumption is challenged scientists to develop environmentally friendly technologies.
The United Nations estimates, up to 2030 energy demand will soar by 60 percent. A total of 2.9 billion people will lack of water supply. Here are 10 types of classified technology that can prevent the earth from destruction.
- Produce Natural Oil.
There is a process called thermo-depolymerization, a process similar to how nature produces oil. For example, carbon-based wastes if heated and provided with appropriate pressure, capable of producing oil.
Naturally this process needs over millions of years. From the experiments ever, turkey manure can produce about 600 pounds of petroleum.
- Eliminate Salt from Seawater.
UN noted, clean water supply will be limited to the billions of humans in the middle of this century. There is a technology called desalination, which removes salt and mineral content of sea water so drinkable. This is a solution that can be done to prevent the water crisis. The problem is, this technology is still too expensive and requires considerable energy.
Now the scientists are looking for a way for desalination can take place with less energy. One way is by evaporation of the water before entering the membrane with microscopic pores.
- Hydrogen Energy.
Hydrogen fuel is considered as an alternative to pollution-free fuel. Energy produced from a blend of hydrogen and oxygen. The problem is how the hydrogen was produced. Molecules such as water and alcohol should be processed first to extracting hydrogen so that the fuel cell.
This process also requires large energy. But at least scientists have tried to make laptops and other devices with fuel cell power.
- Solar Energy
Solar energy that reaches the earth is made up of photons, can be converted into electricity or heat. Some companies and housing has been successful using this application. They use solar cells and other solar thermal collectors as a medium for energy.
- Heat Conversion Sea
Equipment biggest solar collector on this earth is sea water. United States Department of Energy (U.S.) calls, the sea can absorb solar heat energy produced is equivalent to 250 billion barrels of oil per day. There is a technology called OTEC is capable of converting ocean thermal energy into electricity. The temperature difference between sea surface capable of running the turbine and drive the generator. The problem is, this technology is still less efficient.
- Ocean Wave Energy.
Sea covers 70 percent of the earth's surface. Wave of energy saving that can drive turbines generating electricity so. The problem is rather difficult to estimate when the ocean waves big enough to produce enough energy. The solution is to store the energy when fairly large. New York City's East River is currently a pilot project with six turbine-powered water gelombanng. While the Portuguese it was already practiced these technologies and successfully illuminate more than 1,500 homes.
- Planted Roof
This concept is inspired by the Hanging Gardens of Babylon in the list of Seven Wonders of the World. Babylonian palace consists of a roof planted with various flora, as well as balcony and terrace. This roof garden is able to absorb heat and reduce carbon dioxide. Imagine if the birds and butterflies flying around our green home.
- Bioremediation
There is a process called bioremediation, the use of microbes and plants to clean up contamination. One of them is to clean the content of nitrate in water with the help of microbes. Or use the plant to neutralize arsenic from soil. Some native plants turned out to have benefits to cleanse our earth of various pollution.
- Recycling Electronic Waste.
Carbon dioxide is the main factor causing global warming. Energy Information Administration (EIA) notes, the year 2030 carbon dioxide emissions at 8000 million metric tons. The simplest method to suppress the content of harmful substances is to bury a variety of different sources of CO2 such as hazardous electronic waste. But scientists still do not believe that the harmful gases will be stored securely. Still later will show the negative impact on the environment.
- Electronic Books
Imagine, how many tons of paper and how many trees must be felled for the entire world if we all have to buy newspapers, magazines, novels, textbooks, notebooks, fax paper, until the toilet paper. Electronic books or electronic mail, better known as e-books and e-mail very significant contribution to survival. With the technology, production of paper can be pressed, so the material we do not have too many trees cut down.
