#2It seems that for both desalination and sanitation (as discussed in the article) of water is now an energy issue.
What are some other basic problems (food, water, temperature management, etc.) we're facing that are primarily energy-bottlenecked?

#3Waiting for the inevitable explanation of why this is fatally flawed and won’t work at scale?

#4Wow, that’s incredible. Since it uses electricity for it’s energy input, this could be readily adapted for use in remote areas powered by solar plus battery. Even in Western nations this is a boon to treat well water sources instead of shock chlorination.
This combined with GAC filtration can produce very clean water anywhere you can get sunlight.

#5Anytime you read things like 100,000,000 times more effective - you should be asking, what was the numerator or denominator in this. Or are they just describing some tiny part of the system.
For example, normally you need to filter, do settling for sediment etc - how did they solve all this?
Given the orders of magnitude involved here a 5 MGD plant could produce 500 trillion gallons per day of "commercial approach" water cleaning. The water handling issues alone in doing 500 trillion GPD seem large. Am I missing something?

Time to find a way to move crypto to proof of desalination.

#7I just hope the Reactive Oxygen Species that are 10M times more lethal to bacteria aren’t equally more lethal to humans. Also, if this requires electrolysis-level power, it might still not be worth it in most cases.

#8How much gold and palladium are required? Those are massively expensive catalysts and it feels borderline disingenuous to talk about how this will bring clean drinking water to the masses without so much as mentioning cost.

I guess electrolysis of hydrogen from water isn't really a very efficient process so would therefore need a lot of energy.
It's the same reason that we're not all driving around in hydrogen powered cars.
