And it sounds counterintuitive given that enormous amount of water.

But the explanation is that you're not moving it very far.

You're moving it from sort of just below the ice until just on top of the ice.

So, you know, maybe a meter or two.

Listen, there's lots of questions around the feasibility of this project, particularly around scale and accessibility.

But I think energy is probably isn't one to worry about so much.

It's a question of perspective.

So on one level, it's quite big.

It's 450 metres by 450 metres.

You stand there and you can see it.

It's very striking on the ice.

I was there just at the right time, just as the ice was starting to melt.

So you could see the blue meltwater forming all around it and you end up with this kind of island of white.

You could see it from the drone.

I saw it on the plane as I flew out.

You can see it in satellite pictures.

It was impressive.

On the other hand, the Arctic is a gigantic place, and I think every year the long-term trend is we're losing about 80,000 kilometres squared of Arctic sea ice in the summer.

So compared to that, it's pretty tiny, but that's the point of it.

It's meant to be an experiment just to see how feasible it is.
