If you have no safety equipment, your friend is always there to help you. That’s one of the principles of the guest workers who are building a house in Tomsk.
This guy doesn’t need safety equipment either. He managed to reach the top star of the skyscraper in Kotelnicheskaya embankment in Kiev… This video is really scary!
Kharkiv scientists have invented an unusual device that will allow to charge a cellphone from … fire. Even if you find yourself in a wild forest, far from civilization, all you need is to make a fire.
Students of the physical and energetic department of the Kharkiv National University named after Karazin took only a week to invent the device. The idea had been described in a diploma thesis of one of the students.
They bought Peltier element, some electronic components, assembled a connector that converts a weak signal of Peltier element in such an element that is sutable for charging a cellphone. All the details they used had been existing for long but no one ever used them together.
According to the inventers a small fire or a candle is enough to get a charge. They claim that no analogs exist neither in Ukraine not abroad.
The guys assembled the device for some minutes, lit candles, put a cup of cold water on a copper plate – and … the cellphone started being charged …
The unique device weighs a bit more than 100 grams, its cost price is about 150 hryvnas (18,5 USD).
