Clean technologies are those created by man and for man, where the environmental impact is minimized almost entirely with respect to existing energy sources. Nowadays, more and more ecological innovations are leaving conventional ones behind.
Here are some of the technological innovations that seek to save the planet:
- Nanotube Power.
Researchers at the Massachusetts Institute of Technology have recently developed an innovative technology and it is a device that produces DC Voltage that shoots electrons through a carbon nanotube. This artifact is so incredible that a whole branch of science and engineering may have to be created to study this new form of energy production.
In a practical way, this device, called " thermpower " made of carbon nanotubes, could provide the same energy as a lithium ion battery but being 1/100 with respect to its size. It's like your laptop being powered by something the size of a fingernail.
- Zenith Solar Technology
This type of energy uses curved mirrors that can collect five times more energy than ordinary solar panels, this new technology was developed by an Israeli company, called Zenith Solar. Such an invention is competing for the cost of solar energy against fossil fuels, such as oil. These solar panels can improve the total solar energy conversion by up to 75%.
- Vertical farms
While in the world the land is paved every time to make an urban center and farmers must produce more food with less land. The solution to this problem, according to a company called Valcent, is to grow crops vertically.
This company is a pioneer in the hydroponic growing system that grows plants in rotating rows, that is, one on top of the other. Such an implementation not only allows a necessary amount of light for each plant, but also uses much less water than other growing methods.
- Solar tiles
Solar roof tiles do not need open spaces to build solar parks if people put solar panels on the roofs of their homes. That is why thanks to the technology developed by Dow Chemical Co., this possibility is closer to reality, since it has developed a roof tile that works like a solar panel, made of thin cells of copper indium gallium diselenide.
