Yes, looks interesting although I can't see how it helps with rainwater.
Irrigation certainly but not rainwater.

Probably by concentrating its flow to the base of the plant, so more
chance of penetrating deeper into the soil.

And then possibly helping to prevent evaporation?

Yes. A near-total waste of time for the UK, where a simple
depression is quite good enough. And, as David says, only for
irrigation (and fertilisation), not rain.

In countries with higher evaporation, it's different. But,
here, it's a rare day that will evaporate more than 1 mm of
water, so any useful rain will soak in before it evaporates.
