How to build a reliable and durable house? What technologies are currently in use? To these and other questions will find answers in this article. Just note that the choice of technology of construction of country houses include the problem number one is impossible, but often there may be some difficulties, especially in the absence of construction education or insufficient funding.
This velocity model of his own design, is designed to perform a figure of course. The model can be made in the traditional method where the frames are assembled with plywood with thickness of 1 mm, a keel from a piece of wood a cross section of 6X10 mm, the stem is made of plywood of 3 mm thickness, stringers — strips of a cross section of 4×4 mm. the Hull is sheathed with millimeter plywood; experienced modelers make it from fiberglass, pre-prepared matrix. To strengthen the hull glued the keel bar, and extra stringers and a bulkhead separating the engine compartment from the compartment with the radio.
This tractor for almost 20 years, and all these years he not only regularly serves his Creator A. A. Safenano from the village of Alexandrov, the Tambov region, but also constantly improving. A feature of the car is a bucket-loader which is quite rare among self-made designs. This device is good because it optionally can be used as a blade, for example, when clearing snow from roads.
Immediately after his return from Moscow to Koktebel in the fall of 1929 Sergei asked me to do a new airframe for aerobatics, — says the aircraft designer S. N. The lyushin.— There were many reasons that prevented me to take this job, and he began to design what later became SC-3 — “Krasnaya Zvezda”.

Led bulb (abbreviated SL) can be seen today in almost every home. And for good reason-they are economical. Energy conservation is that SL, for example, with a declared capacity of 9 watts and current consumption of just from 0.065 A, is the analog of the output light of the incandescent lamp 60 W, which consumes several times more.
In the history of Soviet and Russian automotive industry was not, perhaps, a more popular car than this modest, but very well built, tastefully done a 2.5-ton truck GAZ-51, or, as in my own way called it the drivers, the “lawn”.

Last three cars — the second generation of the family, whose main difference is a powerful 6-cylinder engine is 4-cylinder the first two. But all machines have a lot in common or at least similar in appearance.
Two hundred years have passed since then, as it became known Seebeck effect and Peltier. The effect is to pump heat under the action of EMF (electromotive force), in other words, the thermoelectric semiconductor element operates as a heat pump.
