In the laboratories of maturing technologies that can open a new page in the energy sector. For instance, many use it bodes bioengineering. But what should be done to such innovation really noticed and started to introduce? We need to create something incredibly spirited, at least on paper. Voila - Meet a hybrid of a skyscraper, the airship, the bioreactor and hanging gardens. French, Belgian Kallebo Vincent (Vincent Callebaut) is quite familiar to our regular readers. His projects are characterized by smooth fantastic shapes based on natural analogues, and the continued environmental orientation - an abundance of greenery inside. The grass and trees, shrubs and flowers, grains and seaweed - all they need to help people make the world a little cleaner. These bionic garden-ship Physalia, titanic farm Skyscraper Dragonfly, Lilypad floating city and cleaning tower Anti-Smog. The new work is done in the same vein. The price of oil hitting record lows, and in completely foreseeable future, as predicted by some experts, the planet could face a noticeable drop in production of energy with an increase in need. So, it's time to think about alternative, argues Kallebo.

Read more: "Our geography" Part 5. Office equipment in the greenhouse. Computer Control The concentration of gases and the environment is under the control of computer hardware and software company Q-Com. Although the software has been reworked a bit for a particular greenhouse. Hothouse In a greenhouse during the day is maintained at a temperature of 24 degrees, and at night near 19 degrees. The fan will work as follows: one, two or all four at once. Evaporator system begins to work when the temperature outside is above 24 degrees. Depending on the amount of solar radiation, which receives the plant each day varies and photoperiod. But as was seen this not as harmful to plant growth and development. The concentration of CO2 in a greenhouse maintained at 1000ppm, with active ventilation gas is not supplied. The temperature of the nutrient solution is controlled by a temperature sensor and with the help of special valves in the heating circuit. The concentration of dissolved oxygen in the solution is regulated by hand, by increasing or decreasing by opening or closing the valve. The concentration of the nutrient solution is checked every four hours for an hour. pH of the solution in each of the four solutions is maintained at 5,8 ± 0,2. Concentration at 1200 ± 50 MKSM. Pricking branch In the pricking-clock room maintained at a temperature of 24 degrees. In the seedling compartment lighting system around the clock. The unit, which cools the water outlet from the heat lamp is equipped with multiple safety systems: a high temperature, weak stream, low water level in the tank, if one of these parameters revealed a system of protection, then all the lights are switched off. Specially manufactured bulb for lamps designed just for temperatures lower than usual for lamps without refrigeration. By hotbed CO2 level is maintained in the 1000ppm clock. Composition of nutrient solution in the nursery is no different from that used in the greenhouse and daily concentration tested, adjusted manually. PH of the solution is maintained at 5,8 ± 0,2 and the electrical conductivity in the region of 1200 ± 50 MKSM. The location of each fixture is designed with the help of special software on your computer, this is done to ensure uniform light throughout the greenhouse. The average light intensity of 200 mmol per meter at the plant, located at a distance of 3 meters from the lights.  Read more: "Hydroponic Greenhouse. Growing lettuce on floating platforms. " Part 4. Growing lettuce. Each day, using a vacuum planter on plates of mineral wool sown 1200 seeds, plates and then placed in plastic trays and transfer them to the pricking room. To maintain the necessary moisture for the seeds, these trays for three days, covered with a transparent plastic lid. In addition, after sowing, trays during the day under light-tight lid, to stimulate germination. 6 days after sowing to sort it, remove the weak and small seedlings. After 12 days in seedling seedlings department moved to a greenhouse. In the greenhouse, transplanted from the new location. Each seedling was placed in a separate box on a raft of extruded polystyrene foam, which floats on the surface of the pool with the solution. In the next 10 days, plants grow on these rafts, and then transplanted them again in the same rafts, but the distance between the plants grown. Until the last transplant plants grown for 14 days. Of the 1200 seeds sown, 12 days later in a greenhouse transplanted 960 seedlings, 22 days is 945 plants. The final weight of 150 grams of lettuce and it matures in 36 days after sowing. Mineral wool, size of 7 to 14 cells before seeding moistened with tap water. They were then placed in plastic trays for easy transportation.  Read more: "Hydroponic Greenhouse. Growing lettuce on floating platforms. " Part 3. Construction of the main building. The entire length of the north side of the greenhouse was built extension, which will house various technical areas. There will be room for work, utility room, sprout room, cold room for storage of finished products, restroom, dock, an office with a computer. The main part of the premises as there are mortar site, room for cleaning products, packaging, Room seed and place of storage of liquid oxygen. Special weather station attached to the roof, it shows temperature, humidity, wind speed and direction, as there is installed a light sensor. Nursery. For the growth of seedlings using a room the size of 6,1 to 7,3 meters. Trays, which planted the seeds of plants, are on a special table, watering is carried out three times a day for 15 minutes, on the principle of tide / low tide. The temperature in the room is maintained at 24 degrees, supported by a special air-conditioning installation. High pressure sodium lamps, which are used in the seedling compartment provide uniform light, which is approximately equal to 350 uM. For illumination of seedlings used lamps of 600 watts, which are specially made to order flask to cool. Through this flask is run the water, which absorbs about half of all heat is a lamp, while not significantly reducing the luminous flux. After the lamp is about 75 liters of water per hour and the temperature of water passing through the flask rises only by 2-3 degrees. Then this water is pumped into a special chiller, which cools the heated water to 30 degrees. Ciller is located on the street. This is done for what would be produced by the warm air cooling heat to the temperature in the room. Also in the nursery uses carbon dioxide to increase the growth rate of seedlings. Installing a wooden frame for the roof and walls  Read more: "Hydroponic Greenhouse. Growing lettuce on floating platforms. " Part 2. Building greenhouses. The beginning of this article can be found here - http://www.ponics.ru/2010/03/floating_hydroponics/ Like everyone, we needed to start to get a building permit. For permission had to be submitted to the Council of the City plan for future building, where he was due consideration and discussion. During the voting plan was approved by council members and was given permission.  Read more: "Hydroponic Greenhouse. Growing lettuce on floating platforms. " Part 1. Introduction Cornell University in 1991, participated in the program for the Exploration of growing vegetables in greenhouses in hydroponics. From the outset, the goal of the program was to develop systems for fresh, high quality greens, without pesticides and whatever vegetable prices were close to the market. Production of lettuce year-round was made possible only through a clear control of the microclimate in the greenhouse and plants to ensure the necessary quantity of CO2. The hardest thing was in the dark winter months, where it was necessary to include and irradiated with additional heating, all this was done to maintain the growth of production. To prove seven years of research and decided to build this demonstration greenhouse cultivation principle which will be based on floating platforms. Construction of the greenhouse was launched in March 1998 and completed in April 1999. The volume of production of lettuce a day at full load was 945 pieces, and so seven days a week. The growth of lettuce is 36 days from seed to collect the finished product, the average weight of harvested lettuce is 150 grams. After construction and commissioning of greenhouses in operation is going on in it was under public scrutiny. Cornell University owns all that are essential for training in vegetable production. It is assumed that the demo Greenhouse provided a further boost to the development of high technologies in vegetable production in New York and beyond Designed and built by Greenhouse consists of two parts. The first part of this branch of pricking the total area of 360 square meters. The second part, the growing area of the total area of 750 square meters. Particular attention is paid to monitoring the environment in the project were used in water-cooling equipment that cools the air in the premises, for dosvechivaniya used high-pressure sodium lamps. Construction was organized entirely on sponsorship money. Seeds of lettuce were donated by Rijk Zwaan.  Read more: "Hydroponic Greenhouse. Growing lettuce on floating platforms. " Another article about cloning or better to say the continuation of already started an article entitled Cloning of plants. This article will consider the option of cloning tomato. I will say that cloning is a very simple tomato plant, but even here there are still a few nuances in this case. First of all, we need a healthy plant, which had already grown stepsons and growth they are approximately 5-7 cm  Read more: "Cloning of tomato." One evening, just last week, Dmitry asked me, as if I had the desire to go to agroholding Moscow? And of course I replied that no, it hurts we have to consider what a blessing to visit Russia, the largest in the complex, which grows plants in hydroponics. In general, this is a joke, but I think you understand what I (smile).  | visiting |  |
