This article is about a tidal turbine constructed in London, England. This tidal turbine made in England, captures energy from the currents and increases the speed ten times the actual stream current. This machine helps the stream currents and as well as the energy to give light, expecting it to give 500 kilowatts of power. Trials are done but within four years it is seen to be completed and used world wide. Even though its expensive, it is worth for our world’s sake.
This is a great invention that will help our planet. It has more advantages since it is small comparing to the others. This will make a lot less pollution than other machines. Lately there are going out many ecological machines. If all the people start thinking like this then we will make a big difference. The bad thing is that it is more expensive, because it is better than normal energy. This is why not many people use ecological energy in their house, the cost. We hope that it will come out in the 4 years it is expected to.
