FOR SAVE WORLD
Fossil fuels are the largest source of environmental pollution in the world. According to the sources, this type of fuel, going towards new and cleaner energy generation, priority will be present. Hydrogen is the most abundant element in nature, has the potential to replace fossil fuels.
USE NATURE, MOST POWERFUL FORCE
Use now energy from the sun and wind, Alternative is the only solution
LED-lamps allow year-round harvest in urban warehouses
In the future, the basis for year-round farming will not accustomed us to the farm, and huge urban warehouses, which are lit 7-8 bands of LED grow light. The researchers found that growing tomatoes using LED lamps in the winter can significantly reduce greenhouse gas emissions without compromising in terms of productivity, while at the transition process technology turns minimizing the costs of the farm for electricity. Scientists say that the new method can change the very nature of agriculture.
One American company has been experimenting with a giant warehouse in Texas, which is hidden inside a huge array of pink LED lamps illuminating plant. About 2.2 million. Cultivated plants here will be under the rays of the sun until the end of his life.
Firm Caliber Biotherapeutics, headquartered in Texas (USA), grows with a new system similar to tobacco plants. Crop will be used for the production of new drugs and vaccines. Former warehouse area of 13.9 square meters is completely isolated from the outside world. Under the ceiling at a height of about 15 meters attached blue and red LEDs.
Photons spend in vain - is silly. Therefore, scientists have developed a specialized LED-lamps. This will maximize the efficiency of photosynthesis, plants flowing inside. As a result, the biomass grows almost 20 percent faster than under normal conditions. In addition, farmers can save a lot of electricity.
Researchers at Purdue University say that this method can be used for year-round crop production. Professor of horticulture Cary Mitchell said that in most cases the same tomatoes available in the country with a cool climate of bred closer to the equator States, overcoming many thousands of kilometers. In cold regions, such as culture can be grown, but in winter it is inefficient from an economic point of view.
The highest yielding lights let you receive the crops all year round - regardless of the place where grown or that culture. Going on a farm with LED-lamps will help farmers actively compete with each other, which will result in lower prices for their products and the most positive impact on the state purses end users. This technology can allow agricultural producers from countries with cold climates to create new jobs, to minimize the carbon footprint of its production and even to grow even more delicious vegetables and fruits (studies show).
Mitchell and his colleagues have long experimented with LEDs, which require much less energy than conventionally used in the greenhouse gas discharge lamps high pressure. They got the same crop - the size and number of fruit - but LEDs use 75 percent less energy than standard bulbs. Scientists believe that the method may have other advantages, as gently heated LEDs can be placed much closer to the garden beds and along the side walls of plants, covering not only the upper part thereof and a bottom.
