## Hydro Power - How it works?(www.addnew.com.hk)

Hydropower Generators & Hydropower Turbines (www.addnew.com.hk) Hydro Power - How it works?

Internationally, about 20% of all electricity is generated by hydropower - the world's most widely used source of renewable energy. In Nepal, 100% of electricity is generated from hydro sources. In countries such as Peru, Brazil and Norway, more than 85% of their electricity uses hydropower. In New Zealand, about 60% of electricity is generated from hydro sources. In China till 2009, about 22% of electricity is generated from hydro sources.

Hydroelectric power stations capture the energy of falling water to generate electricity. Two factors are used to assess the generating capacity of a waterway. The first is the quantity of running water, or 'flow rate', measured in cubic metres per second. The second is the difference in vertical metres between the intake pipe and the turbine outlet, or 'head'.
Formula:
Theoretical power available (kW) = 9.81 x Qc x H x Overall Efficiency
Where Qc = flow in metres3 per second

When considering other factors, such as the efficiency of machinery, pipeline friction and the need to keep residual water in the stream, the practical output is less than the theoretical output.

Hydropower works by converting the movement of falling water into electricity. Many forms of hydro power exist and have been used by humans throughout history, some examples of this are watermills powering machinery such as sawmills and farmers irrigating land using gravity. Most often water is stored in dams or reservoirs. This water flows through an intake and into a large pipe called a penstock. The penstock then feeds water into a turbine which powers a generator.

The turbine is powered by water flowing through the wicket gate. This gate can be controlled to determine the rate of flow through the turbine and therefore the amount of power generated. The turbine is attached by a shaft to an electric generator. Transmission lines then take that electricity where it is needed at the time.

Some common terms:

• kWh Kilowatt hour. This is used to measure electric power use. A kWh is commonly referred to as a "unit" of electricity. A typical one bar electric heater running for one hour will consume one kilowatt of electrical energy.
• GWh: Gigawatt hour – one million kWhs or units.
• Head: Difference in vertical metres between the intake pipe and the turbine outlet.
• Penstock: A high-pressure pipe extending from the first upstream water surface to the turbine.
• Wicket gates: Angularly adjustable streamlined elements that control the flow of water to a turbine.
• Turbine: A machine that converts the energy of falling water to mechanical energy.
• Generator: A machine that converts mechanical energy into electrical energy

## 抗議貿然被改名

「二次創作」一直都是版權討論裏的關鍵詞，於新聞報道及在學術界使用率甚高。至少這些年間香港的版權修訂爭議都是如此。只要搜尋「二次創作」於香港新聞媒體、香港政府及立法會等的出現數量，以及「演繹作品」的出現數量，便能馬上知悉。我不知道User:Pengyanan的更改有什麼依據，但這樣很有問題。要求馬上先還原作有根有據的「二次創作」，即本來使用的名字，改名者並提出更改的具體原因，得到共識後才進行處理。Tvb10data留言） 2014年5月31日 (六) 18:30 (UTC)

Q4. 可是，知識產權署聲稱「二次創作實質涵蓋範圍難以確定」，爲甚麼會這樣？

## 强烈抗议管理员单方面把衍生作品合并到二次創作

Q6. 此外，也有人聲稱「二次創作」只限於指日本同人誌的改編作品，他說得對嗎？

## 本條目近日遭受破壞

• 河蟹或消滅掉條目上所有過往列擧的文學上的二次創作實例
• 河蟹掉一些創作人表明二次創作立法的言論
• 把二次創作這種人類創作歷史上屢見不鮮的尋常創作手法，扭曲成「二次创作事实上就是对原作的上述权利进行了侵犯」、「二次创作无论是否盈利，在事实上已经构成了对原作的侵权」等
• 把二次創作說成必須「征得原作著作权所有人许可并支付报酬」變成「奸商收數遊戲」，扼殺創作權利
