#2does the ocean still clean these days ?
very nice job, expect to see it available soon

#3I'd love to see an energy-conservation analysis of this technique. How many joules per liter does it actually require?

#5It would be great if a Solar cell or small panel could power it. That could be a life saver in emergency situations.

Yeah, I'd recommend that link. It's slight more technical and written in a neutral voice. The original link feels like more of an excuse for a rant against the IMF.

A solar panel can run this. Or, to be more specific, a small (3" x 3") solar panel could charge a 3v battery which could power this device. I have solar-powered holiday lights which operate on 3v, this application would be simply replacing the lights with this chip. I've actually replaced the charging circuit with a TI MSP-430[1], and powered it directly with solar power.
[1]a microcontroller similar to Arduino which operates on 3.3v and was intended to cost $4.30 for the entire development kit. http://www.ti.com/msp430

40 nL of desalted water per minute, for a minute, using 3.0V voltage (from article) and 0.7 A current (standard AA, "store-bought battery" from article), yields 3.2 GJ/L.
Even if we give it the benefit of the doubt and say we're overestimating the current by a factor of 100, 32 MJ/L still a ridiculous amount of energy, and ~10x more than just distilling water through evaporation, which is 2.23 MJ/L.

I suspect you got downvoted because English isn't your first language.
Something like: "Is the water from the ocean clean enough to drink? Hope to see this product available to buy soon" might be better
