This is nothing more than plastic gutters buried underground. The ‘engineered’ shape keeps the water from draining away.

This is not new. This is ancient technology. People have used clay pots for a similar effect for a thousand years. I did something like this for my rose bush here in Arizona. I buried some plastic a few feet out from the bush. When I water, that area retains the moisture. This is nothing more than common sense.

Thank you for pointing out the obvious. This is yet another government funded “study” boondoggle.
