The product in life
Recently, there are so many kinds of new energy developed by researcher. Tidal energy is one kind of new energy.
Two different kinds of forces, when they group together, they can cause Tidal Forces. One is the gravitational force of the sun and the moon, the other is the centrifugal force of the earth (when it moves around the moon and itself rotation). Tidal forces cause tide. Tide can have a advantage. When seawater rise or ebb(the place from high to low), seawater through the dam, push turbine to generate electricity.
As for nowadays, wasting of resources has already become a serious problem. Also, it has been a threat to the existence and development of human begins. To solve this problem, the idea of ‘Develop New Energy’ is taken more seriously by people.
Do you want to know what does the tidal power station really look like?
Statement of the problem

The tidal power
could be use...
Tidal power is a kind of renewable energy. It won’t be use up because it can reborn again.
-Tidal power is a kind of clean energy. It won’t produce any pollution when it turn into electricity.
-The tidal power generation takes advantage of vantage ground like gulf and estuary. People build dams and reservoir here in order to save up an enormous amount of water.
-The direction of the tidal can be change at every second, so the form of the tidal power generation not only can be the single-track, but also can be the both way.
-A kinds of the system of tidal energy generator set that can generate electricity for the whole day has 2 reservoirs. One is the elevated reservoir (only inflow of water when flood tide). The other is the lower reservoir (only draw off the water when ebb tide). Between these 2 of reservoirs has water level difference.
-The system of tidal energy generator set don’t need to build high dams.
So now let's show some pie charts after we researched.
Residential & Commercial
China’s energy consumption in 2014
In 2002, China imported 6941million tons of crude oil
Crude oil comes from
Total installed capacity and generate electricity of China’s electric power industry in 2014
In 2004, China consumed 1566.3 million tons of coal
There are some data about our
materials and final test...
1 .We should let this model opera te. we should let this model have electricity.
2 .This model should be beautiful and easy to see how it operat e.
3 .This model can not easy to break.
4 .It should be easy to make.
5 .We should use waterproof material to make this mod el.
Materials Cost Q uantity
water vat 100 1
turbo machinery 20 1
current lead 3 8
water 0 1 tub of water
bulb 5 4
plastic board（city model） 50 40
Some pictures to show...
Test and Evaluate Solution
Number Result Reason
1 Fail The electricity is no t enough.
Succeed L ittle brightness, because the water flow
is not very fast to let water wheel move fast.
3 Succeed The electricity is enough.
Refining the design or Redesign
-We decide to make a new holder for our big bottle which imitates the tide comes from the high place push the turbine to work to create the current.
-We decide to change another turbine which has higher power so that it can create enough current and light all the small bulbs of the whole city.
Our model is fit for those people who live in the coastal city .
