The Economist.
Nikita Ostrovsky, you write about science and technology for The Economist.
So why have you brought me outside?
I brought you out here so that we can feel the heat.
It's been the hottest summer in Western Europe on record.
And I think that's important for today's episode.
I mean, you're in the shade.
I'm in the direct sunlight.
It's pretty hot.
It's definitely more pleasant inside.
Shall we head back in?
Let's do that.
If we step inside, you'll feel and hear that we have a very effective way of staying cool indoors.
It's freezing in here.
It is cold in here.
This is good.
This office can be hot when it's cold, cold when it's hot, too hot when it's even hotter outside.
But no, the air conditioning is working.
It's lovely.
It's not failed me yet.
