Check out Thunderf00t&#x27;s videos cricising solar water collectors, e.g.:<p>- <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=vc7WqVMCABg" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=vc7WqVMCABg</a> -  Zero Mass Water: BUSTED! &quot;Honestly, it drives me crazy how many people have reinvented the dehumidifier, put a solar panel on it, and the media has danced around like theyve just saved the world!&quot;<p>- <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=aPvXnmBIO7o" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=aPvXnmBIO7o</a> - Self-filling water bottle: BUSTED! &quot;<i>The fact that its thermodynamically impossible seem to stop &#x27;science communicators&#x27; from promoting this.  The fact that its a really dumb, and not particularly inventive idea didnt stop the &#x27;science communicators&#x27; from promoting this.  Kinda depressing really.</i>&quot;<p>Problems include:<p>- it&#x27;s much cheaper to bring in a tanker of water from somewhere else, than for the electricity to do this.<p>- It&#x27;s a dehumidifier; in places where the air is wet, it rains, and you don&#x27;t need it. In places where you need it, you need it <i>because</i> there&#x27;s not much water, so it doesn&#x27;t work well.<p>- It&#x27;s going to be prone to growing bacteria; warm and moist.<p>- It needs a vast volume of air; when water becomes steam it expands 1000x. Which means to go the other way you need at least 1000 litres of steam dragged through for a litre of water. Air can be around 4% water says Britannica.com, so 20,000 litres of humid air for a litre of water if it&#x27;s perfectly efficient. Thunderf00t&#x27;s estimate is 50,000 litres of air for 1 litre of water; And the air needs to be cooled.  That needs big fans and lots of power (air is heavy to move).
