A machine that causes the rain
Jan 19, 2011
But not in every desert it can earn. From observations made during the experiment, it was found that this process can be started only when the humidity rises to 30 percent. This indeed is often the case in the United Arab Emirates, located on the coastline. But in the deserts like the famous Atacama in Chile, where the humidity is at 0 percent, above the lamp Chizhevskogo unlikely to be able to cause even a "mushroom" rain.
In addition, another disadvantage design is that it uses a lot of electricity. This, as you know, not a problem for the oil-rich United Arab Emirates, but hardly like "rain" of the machine can be operated in the African desert, because many of the state on whose territory they are located, are poor in energy resources. However, the developers can not exclude the possibility of modifying plants so that they worked on power plants, operated by the so-called alternative energy sources.
It is interesting that such experiments were immediately concerned with the different greens, who have decided that under constant irrigation of desert rainfall to climate may change, which entails the extinction of living there, unique animals and plants, the spirit of not tolerate high humidity. But the creators of the installation calmed fighters for the preservation of nature, stating that no one intends to keep the "rain" of the machine is constantly switched on, since it is not enough money even for rich United Arab Emirates. It is just about to call from time to time a rain, when it will take to local residents.
Despite the fact that between experts from different countries were received warnings that the experience of Swiss firms are required to be subjected to additional testing, the results were good reviews of colleagues, including the prestigious Institute of Meteorology of the Max Planck in Berlin. Developers were told that in two years maybe mass production of such "storm" of machines. Maybe it was then that the cherished dream of people finally be able to be realized.
It remains only to regret that Russian specialists whose efforts had the first lamp Chizhevskogo, and could not come up on it "rain" car. But such a setup would be very useful during the abnormally hot summer last year! It remains only to hope that they will be able to construct something like this in the near future ...
Sand Glass - stoplight hourglass
In many cities, traffic on highways regulated by modern lights, which counts the time until the change of the signal. There are both audible traffic lights (they are most commonly used on pedestrian crossings, which facilitates the passage of streets for pedestrians with impaired vision), and digital versions, showing the electronic dials the number of seconds left before the regime change movement.
Recently there was yet another unusual idea of a traffic light, which is used to indicate the time of the hourglass model. It's - Sand Glass. In addition to the LED hourglass image of red, yellow or green on the main board of the traffic light is located and an electronic timer that displays seconds remaining in the figures. It is only at first glance, it seems superfluous and unnecessary luxury. Meanwhile, it is counting in the figures allows drivers as clearly as possible to know the time of regime change and prepare to stop or contrary to the motion - in advance.
Certainly, many of you have a question - how expensive to manufacture such a creative fun on the road? Cost Sand Glass is lower than that of any traffic on the LED matrix. Indeed, in the Sand Glass yellow (left developers, apparently as a tribute to tradition), in fact, is losing its relevance and, hence, production costs can be reduced. After deciding not to yellow, and there will be no need for a yellow light-emitting diodes. Agree, always a pleasure to enjoy comfort appliances, knowing that they are even cheaper than the old.
