  • The juice itself is… of moderate known negative impact. The nicotine itself isn’t actually very bad for you. Some of the flavoring though is pretty questionable. Compared to combustion it is likely still quite a bit less negative for your health in most cases.

    The exception is the hardware, it seems quite likely there is mass lead and other heavy metal poisoning happening due to poor quality metal and ceramic components in vape hardware. I work in a related industry, and this conversation is being had internally by the big players who are afraid of potential class action lawsuits coming down the pipeline while pure export companies from China and elsewhere sell bulk wholesale of low quality hardware. Vapor composition certifications are coming soon, but the damage may well be done for a generation.







  • Basically in areas where desalination is used for mass water production pure water is the resource in shortest supply and therefor osnhigher value than electricity. Wastewater is a potential source to feed RO systems to generate pure water, any water source with a lower concentration of solute than seawater is a potentially more efficient feedstock for the RO purification than seawater. Given that RO purification takes more energy than the energy generation system discussed here, it would be more efficient and therefore cost effective to mix the wastewater into the feed stream and produce a less concentrated brine waste output rather than use it to dilute the brine waste after the fact. The more concentrated the brine output from an RO plant, the more energy it takes to produce due to diminishing returns as the osmotic pressure increases with solute concentration.

    There are exceptional cases, as I mentioned, where the composition of the wastewater stream will make it so that concentrating the solute in that stream has an economic incentive greater than the demands for RO water. In those cases diluting the brine may make economic sense. The location of the plant impacts this as well, there may be some edge cases where transporting the brine to the source of wastewater and processing it there on site may have an economic advantage. I’m thinking of nuclear waste and high toxicity chemical plant waste here where release is not an option and storage is mandated, so the waste stream will need to be both segregated from other less toxic waste and stored long term.
