So in terms of cost, that is really true.

Our machines often do not just run one year, they run for sometimes decades.

So that's always the biggest challenge to get the customer convinced right from the beginning.

We also had it that like during the project, we figured out, look, customer, with that machine you want, you're going to use, let's say, three million gallons of water every year.

And then suddenly, what can we do? And then we say like, well, we are in the middle of the design phase.

We can still rebuild your machine, but this will add more time and more costs to that.

And so coming back to your question, it's actually important to already know what you want as early as possible, because that helps us to finalize the design and also to already know in advance what it will cost.

So what do you think we look like in five years, 10 years?
