I love reading about alternative energy that can be used for power generation . And now I 'm reading about the conversion of water power into electricity . And I tried to write it here . I found an article about a village whose inhabitants use electricity made from river flow . you can read here . If you do not understand the language , you can use google translate to translate .

River in the hills , suitable for waterwheel . because river water usually has a heavy water . So with a rushing stream that can be used to rotate the paddle wheel . And with the concept of energy conversion , the round wheel can be used to rotate the turbine , and electricity can be raised .

For some people, math is a difficult subject to master. If parents who have problems like that, of course, will have trouble when they serve as a math homework help for their children.

I think, there are many ways to learn math again. For example, by using an online tutorial that provides math statistics help , calculus help , geometry help , Algebra 2 Help and others. I think, our kids will be more proud of us, when we could help for their math homework.
