New rooftop solar hydropanels harvest drinking water and energy at the same time

Reading Time: < 1 minute

In many of the places that have abundant solar energy, water is scarce. This new solar panel product can produce 10 liters of clean drinking water per day.

Sunlight + Air = Water . It’s a befuddling equation, but it’s at the heart of a new solar hydropanel developed by Arizona-based startup Zero Mass Water .

  1. Seriously, they advertise the ability to remove water from 5% air? That should be a red flag to anyone watching. I am getting a very big deja-vu from the water-seer scam.

    Secondly, the cost itself is ASTRONOMICAL. Even if we take their as-advertised costs (which sound right) their as-advertised production (which seems quite high) and assume that they don’t have any drop-off of efficiency (engineering impossibility). You get a cost of $0.30 per liter. That is literally 100 times what I pay for water.

    Look at this cost of desalination, which has a graph with units of $/cubic meter. And Desalination is known worldwide as the most expensive method of getting potable water.

    Any location that could afford such a design has far better methods of acquiring water
