Scientists have learned to turn the snow into electricity

Snow carries a positive charge

Two scientists from the University of California in Los Angeles invented a device that uses silicon to capture electric charge from the snow and turn it into electric current, reports the Chronicle.info with reference to Wave.

In fact, it is a surface which is simple, thin, flexible, inexpensive, it does not need any batteries.

The average annual amount of snow on the entire planet is about one-third the mass of Earth. This is a huge amount of energy that humanity can use without causing absolutely no harm to the environment.

However, the device is nothing more than a prototype, only proving the possibility of using the energy of falling snow, as its power is very low. At eight volts voltage a device can produce a maximum current density of 40 microamperes per square meter.

This means that even if you create a surface area in square meter, the amperage is still not even enough to light a led light bulb. But the creators are already looking for ways to improve their unit in order to increase its efficiency and make it suitable for use in real life.

How it works is deceptively simple. Snow carries a positive charge, and the silicone negative. When falling snow comes into contact with the silicone, you may transfer electricity through the circuit. The snow creates a charge on its surface, as water molecules are ordered, when kristallizuetsya in snowflakes. When the authors learned about this fact, they thought, why not use a different material with an opposite charge to generate electricity.

For the manufacture of the device they have created a layer of silicone and another layer of conductive plastic, charge collection after his contact with the particles of snow. So simple on the surface can create electricity with falling snow, and the larger the surface area, the higher arise in circuit current.

During the operation in the man’s chest caught fire

According to the creators of this surface, it will find many uses. For example, it can power a portable weather station or a wearable gadget that tracks the performance of athletes in the cold. According to them, the device also can be integrated into solar panels, for added power during snow storms, when solar panels are ineffective.
