British scientists developed can collect the banner of solar and wind power

Solar photovoltaic webex: scientists at the university of Manchester, England has developed a banner, can harvest solar energy and wind power at the same time. Although they currently insufficient power house, even can't charging products, such as smart phones, but enough to sensor power supply for the environment. This energy collecting device using inverted flag set, can move freely of leading edge, but rear is fixed, in contrast to the government buildings outside the wind flags. The body of the

this flag is composed of piezoelectric and flexible photovoltaic cells, these article piezoelectric swinging in the wind energy collection, while the flexible photovoltaic cells capture solar energy.

in under the action of wind, the flag from side to side in the form of repeated bending, also known as the limit cycle oscillation, which makes them very comfortable using uniform deformation of the piezoelectric material to produce energy. Brought double benefits at the same time, the flexible solar panels, as volatile substances, under low wind speed trigger flag flapping movement, of course at the same time able to capture ambient light to generate electricity.

first nuclear fusion of hydrogen, and then release the huge energy. However, its appearance as a stove, but the principle of the energy release are the same and the sun. A ball of fire & ndash; — Hundreds of millions of degrees of the plasma, it with the method of magnetic levitation, any container material does not contact with the surrounding, can control the heat it, at this time, and then create the sun. The EAST is shaped like a doughnut, it USES the superconductor, with minimal energy consumption to get the strongest magnetic field. According to relevant data show that the device 11 m, diameter is 8 m high, compared with 400 tons in weight.

these flags will not produce too much power, but the research team believes that the power can be used to drive environmental sensors, monitoring air pollution, noise, and the urban environment temperature, of course, also can drive small portable electronic devices.

according to the set consulting set the state of new energy, new energy research center network ( EnergyTrend) The latest data, the mainland polycrystalline silicon material for an average of RMB 72 in January 2019. 4 / KG, more than the average price of RMB 75 in December 2018. 5 / KG to reduce the 4. 11%; Single crystal materials in January for an average of RMB 79. 2 / KG, and last month, compared to RMB 81 / KG down 2. 22%. The China of polycrystalline silicon material 1 month for an average of US $8. In December 953 / KG, more than the average US $9. 39 / KG reduced 4. 65%
