Comment on Desalination system could produce freshwater that is cheaper than tap water
NOT_RICK@lemmy.world 1 year agoIf you read about this device you’ll find it’s solar powered. This isn’t anything new, solar powered desalinization boxes are nothing new, but this one doesn’t get clogged quickly like previous models have. If it scales up as well as they’re hoping this could really help a ton of people.

Solar panels also have an issue that come with it covering the earth with more black surface which is negating the point of what the ice was doing to cool the earth before it melted. Ocean water is black and solar panels are black. This is known as albedo effect.
then you have the issue of helping people. Sure, helping people who have NO ACCESS TO WATER this should definitely be an option.
But offering it to people whom already have tap water and access to water as a secondary ‘cheaper’ option is not so altruistic particularly if we don’t consider the impact as the aforementioned non reflective surface that is a much bigger impact on global warming. Hence that solar panels aren’t an all-source solution for the overall issues.

They’re not solar panels, they’re solar powered by a black sheet that heats up the box to get the water evaporating. Creating clean tap water also takes energy so unless the effect of the box’s lower albedo is greater than the environmental cost of cleaning and transporting water it’s still a net positive, especially in those parts of the world where fresh water is scarce.

Again, not arguing if it’s needed where water is scarce, So the topic is switching to a cheaper form for tap water and this is being sold as an idea to people who already have water.

I saw that more of them contextualizing how cheap it is but I could be wrong
