Q & A

What is the main cause of the Earth's suffering due to extreme weather?

The main cause of Earth's suffering due to extreme weather is global warming, which results from the indiscriminate use of fossil fuels and nuclear power.

Why is nuclear power considered a dangerous energy source?

Nuclear power is considered dangerous because it can lead to serious problems such as natural disasters, including earthquakes, and environmental pollution.

What is tidal power generation?

Tidal power generation is a system that produces electricity by harnessing the flow of seawater during the incoming and outgoing tides, using the gravitational forces of the sea and the moon.

How does the Shiwa tidal power plant work?

The Shiwa tidal power plant operates by generating electricity when the tide comes in, using floodgates to allow seawater to flow into the plant and generate power. The system stops generating power when the water level reaches a certain height, typically around 2 meters.

What is the biggest problem with the single-current tidal power system at the Shiwa tidal power plant?

The biggest problem with the single-current system is the environmental damage caused by the reduction of the intertidal zone due to the closing of floodgates before the water level reaches 2 meters.

How does the double-current tidal power system differ from the single-current system?

The double-current tidal power system generates power during both the incoming and outgoing tides, unlike the single-current system, which only operates during the incoming tide. This increases production efficiency and reduces environmental damage.

What are the advantages of the double-current tidal power system?

The double-current system has the advantage of maximizing energy production by utilizing both the incoming and outgoing tides. It is also environmentally friendly, as it ensures minimal impact on the intertidal zone and allows for more efficient energy generation.

What is the cost of producing 1 kilowatt of energy from different power sources?

The cost of producing 1 kilowatt of energy is as follows: solar power costs 400W, wind power costs 200W, single-current tidal power costs 91W, and the double-current tidal power system costs 45W.

How much potential tidal electricity is available globally?

The global potential for tidal electricity is estimated to be between 22 and 44 trillion kilowatt-hours annually, surpassing the current global power demand of 17 trillion kilowatt-hours.

What is the significance of the hydraulic changing double-current type tidal power system?

The hydraulic changing double-current type tidal power system is considered a revolutionary technology that can address global energy issues by providing a sustainable and eco-friendly alternative to fossil fuels and other traditional energy sources.
