Nearly all passive water-from-air devices described in articles are based on false claims. Peltier-based, desiccant/absorption/adsorption based, etc. All end up not working, or not existing. This has been common for ~10 years.

Which category does this fall into?:

  - Fraud
  - Incompetence / misunderstanding that wasn't cleared up prior to publishing an article
  - Neither; this works as expected
