Autonomous electric vehicle for urban master-lay is born in pain. The searches are in many countries and firms, and individual enthusiasts, yet Balk at the same impasse: power, drive. Design created by analogy with the used in production areas, being “dragged” on the streets, reminiscent of a fish out of water — they also “choke” from lack of electricity, the power required speed. Because the developers have to deal with existing types of batteries, the energy intensity which does not allow to use electric motors, similar in power to the internal combustion engines. Hence, not the same acceleration and ground speed, and the range obtained is very far from desirable.
ELECTRONICLY TAKE A RUN-UP
We have already talked about several episodes of the British cruisers, latecomers to participate in fighting the Great (First world) war. But the “mistress of the seas” and are not left alone. The others made where large and absurd mistakes, remained throughout the five years of war entirely without much-needed combat units, which are then rebuilt “into the void”, or even never born.
As you know, the greater the number of elements in the design, so it is less reliable. To increase the reliability of electronic devices and selection circuitry. This will be the conversation below.
Permissible variation of AC voltage in household electrical network In the 220 — ±5 %. A more significant increase in voltage may result in damage to consumers of electric energy. In the cities, compared to villages, mains is more stable, which is ensured by the presence of numerous compensation substations, powerful transformers which equalize” voltage with changes in energy consumption However, in spite of it. in the evening and night hours, especially in summer (when not in use electric heating devices) due to the natural reduction in electricity consumption (all asleep), the voltage could rise to 245 — 250 V.
Car SKODA factory after the collapse of the Czechoslovak socialist Republic to a market economy was on the verge of bankruptcy and in 1990 became a subsidiary of Volkswagen-Audi. In October 1994, on the basis of the model Favorit in conjunction with the company VW was designed a compact car with Felicia volkswagenaudi motor with a working volume of 1,6 l, and in 1996 on the chassis of the VW Golf was published in five-door hatchback Oktavia.
Folding bike nowadays. However, its dimensions even when folded, not too small, and to keep it at home and even more to transport on the bus or tram is not always convenient. I set a goal to develop a convenient folding bike smallest possible folded size. I wanted it to be easily transformed into a suitcase size with the usual “diplomat”. I have to say, this was not achieved, but to construct a two-wheeled machine, which, after transformation to fit in a suitcase or bag with the size 650x450x150 mm, I still did.
There is probably not one family that would not receive greeting cards. Over time they accumulate quite a lot, and most of them are usually thrown away. Meanwhile, postcards, due to their rigidity, can be used for making toys, interesting and useful to young children. Here are some of them.
