Free energy wind always encouraged and designers-professionals and enthusiasts-homebrew to many attempts of its use. However, it was not so easy because of the “swampy” nature of the source. It should be noted that at present there are many wind turbines of various designs, capable of operating with high efficiency and effectively accumulate energy in the most convenient form of energy. However, the production of such wind farms on their own – a rather difficult task.
April 23, 1968 carrier rocket 11А511 was launched into orbit a new spacecraft 7K-OK, called the “Union”. The ship was piloted by pilot-cosmonaut, hero of the Soviet Union Vladimir Komarov. During the flight revealed a lot of failures due to the imperfections of design, what was the reason for the reduction program. On April 24th, during the descent from orbit, the crash occurred — refused recovery system of the lander. He was broken from hitting the ground, and an astronaut, unfortunately, died. It was the first victim of manned spaceflight.
In the production of construction or repair work is necessary to use the platform and the supporting part to them — goats. However, the latter is usually calculated at a certain fixed height, and work on them is not always convenient. I use them instead of the two step-ladders. Changing the location of the platform Read more…
Many farmers dream of a mini-tractor. It can be purchased in the store or do it yourself. But the benefits of a mechanical assistant would only be the case if it comes with tools that allow to mechanize agricultural work. One of such tools — a homemade trailed two-row potato-planter, which will be discussed.
Beautiful stand for climbing plants derived from wood (plywood, timber) of a disk and a wooden rod or of the dural tube of small diameter inserted in its Central hole. From the edges of the disk to the top of the rod can be stretched the colored cords or ribbons — the plants will climb Read more…
