This giant ship has 10m blades that make electricity out of ocean currents

An aerial view of the giant tidal turbine.

This is the world’s most powerful tidal turbine and it makes clean energy for 2000 houses.

It’s called the Orbital 02 2MW, which is a bit of a mouthful to say out loud.

How it works is the whole thing is towed out into the middle of a channel where the tides flow at top speeds.

It has two steel legs with 10-meter blades on the end like a plane’s propeller.

These are lowered into the water with hydraulics so they sit underwater.

The blades then spin with the tide to create electricity, basically like a wind turbine but with water.

The energy then gets fed along a cable on the seabed floor, back to an electricity hub that can power homes nearby.

Where is the Orbital 02?

This giant machine is anchored in Fall of Warness, an area in the UK famous for powerful tides.

The water there rushes between small islands at three meters a second.

That’s quick, it’s faster than what a lot of people can run.

If you run a 5K that fast you’d finish in 27 minutes (which is not too bad at all).

OK cool, so tell me more about this tidal turbine

So the welded steel hull is 72 meters long. That’s about the same distance as the wingspan of a 747 jumbo jet.

Some hardcore chains are used to hold it in place when it’s set up, otherwise, the tides would just wash it away.

These chains are so strong that each one could lift more than 50 double-decker buses.

All the engineering is incredible, but it’s the clean power the Orbital 02 makes that is the most important thing.

The energy can power 2000 homes in the area.

And it can offset about 2200 tonnes of C02 production a year.

The whole project has taken about 15 years of design and building to get to where it is now.

And it’s the type of machine that could really help change the way we think about electricity.

Imagine a future where your EV car is hooked up to power from a tidal turbine – that’s pretty cool.
