In traditional power plants, fossil fuels like coal, oil, or natural gas are burned to create heat. This heat is used to produce steam, which spins a turbine connected to a generator, creating electricity. In renewable energy systems, natural forces like sunlight, wind, and water are harnesse...
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...

With a new technique, scientists have essentially figured out how to create power from thin air. Their tiny device generates electricity from water droplets in the air, and it can be made from nearly any substance, scientists reported in the journal Advanced Materiuls.The invention involves two ...
An electric generator is a device that converts mechanical energy obtained from an external source into electrical energy as the output. It is important to understand that a generator does not actually “create” electrical energy but forces the movement of electric charges in its windings through...
If the location is, in fact, remote, it may not have electricity, drinking water, gas, sewage, or solid waste collection. But there remain several possibilities for a life with comfort and without neighbors. What are the main solutions to enable this and how can an architectural project ...

It's also totally free of charge this machine. Once you'll be able to obtain the machine ready to go. You'll be able to create just as much energy for your house as you would like. This is the way the magnetic energy generator works in creating electricity. The fundamental ...
Tidal Energy or Tidal Power as it is also known, is another water based power that exploits the vast energy source of the oceans tides to generate electricity. Tidal Energy is a “sustainable energy source”, as the Earth uses the gravitational forces of both the moon and the sun everyday...
Most electricity is generated by burning coal and other fossil fuels. Every time you turn on the lights, you create a little pollution. (See the sidebar.) In fact, the average home pollutes more than the average car! (See my Carbon Footprint Calculator for the numbers.) So saving ...
