With a new technique, scientists have figured out how to create power from thin air. They have designed a tiny device that generates electricity from the air's humidity(湿气) and it can be made from nearly any material, scientists reported in the journal Advanced Materials.The invention involve...

How to generate electricity by using a pressure difference and convert it into distilled waterPURPOSE: A method is provided to generate power and create distillation water by lowering atmospheric pressure in a tank in such a manner that water placed in a ground is withdrawn into a high place. ...
The charts show the sources of the electricity produced in four countries between 2003 and 2008. Summarise the information by selecting and reporting the main features, and make comparisons where relevant. Write at least 150 words. Task 1 饼状图 - - 范文 答题 Some people believe that governme...
Static electricity occurs when an electrical charge builds up due to friction between two different objects, usually items that are not good at conducting electricity. You've probably had static electricity in your clothes and hair when they were clingy.
Meanwhile, a lower cost gives PHEVs a competitive edge in the global market where electricity hasn’t become more cost-effective than oil in many countries, driving auto dealers to include more PHEV in their sales strategy to expand customer bases with lesser investment in R&D and manufacturing....
leading to the power station that opens during the day and closes at night. Water flows during the day to generate electricity through the power station turbines. The generated electricity is then sent to a national grid through power lines while the excess water runs to a l...
don't want to use a nail, you can use a pencil as the core for the wire spool. If you don't have a crank, you can make a simple one out of metal or plastic construction toys. For simple demonstrations of electricity, just glue the magnet to the end of a pencil and spin it by...
When waves come toward the shore, people can set up dams to block the water and send it through a large wheel called a turbine(涡轮机).The turbine can then power an electrical generator to produce electricity. “The resource is huge, ” said Janet Swain of the Worldwatch Institute.“We ...
Just like in the solar system, the nucleus is large compared to the electrons. The atom is mostly empty space. And the electrons are very far away from the nucleus. While this model is not completely accurate, we can use it to help us understand static electricity. ...
