"So don’t forget to also buy a small portable solar panel. You can get them online for about $70."
The cost of the solar panel is mentioned but not the actual unit? Neither is the amount of water produced in a set amount of time. Good product but weak article.
Looked at the abstract and found: "The portable system desalinates brackish water and seawater (2.5–45 g/L) into drinkable water (defined by WHO guideline), with the energy consumptions of 0.4–4 (brackish water) and 15.6–26.6 W h/L (seawater), respectively." https://pubs.acs.org/doi/abs/10.1021/acs.est.1c08466
