Renewable energy: CETO system converts sea waves into zero-emission electricity

The CETO system harnesses sea waves to generate electricity using steel buoys that produce 240 kilowatts. These buoys are placed at the Australian naval base HMAS Sterling and are designed to withstand extreme weather. The system pumps high-pressure water to an onshore power plant via a subsea pipe, spinning turbines to produce carbon-free electricity. Additionally, CETO can power desalination plants by using high-pressure water for reverse osmosis to remove salt from seawater.

What is the primary purpose of the CETO system?

• To monitor marine life

• To measure ocean temperatures

• To provide navigation for ships

• To generate power from sea waves

How far apart are the buoys placed at the test site?

• 15 kilometers

• 5 kilometers

• 11 kilometers

• 20 kilometers

What feature makes the buoys less vulnerable to extreme weather?

• Their material

• Their size

• Their underwater operation

• Their color

What is the role of high-pressure water in the CETO system?

• To cool down the turbines

• To spin the turbines and generate electricity

• To clean the buoys

• To transport fish

Besides generating electricity, what other function can the CETO system perform?

• It can track ocean currents

• It can power a desalination plant

• It can predict weather patterns

• It can store solar energy
