Brave Blue World: soluzioni innovative alla crisi idrica

This film tells us about inovative ways of conserving water, conjuring water where there is none and dealing with it once it becames waste.

Full of vaporware tech. It was painful to watch. So many contradictions between chapters. The odd chapters was interesting just to see existing industrial complex but mostly awful. And the narrative was just silly. How is this 7+ stars.

'It never ceases to amaze when the critics come out to play. I just can't figure out why they've zeroed in on a *positive* piece as this. It's astounding. I'd normally ignore yet I know for a fact - human nature dictates - there's hundreds of positive folk for each 'hater' (scientific or bias accuser) up here. Yes, I get that there's DuPont and others. I concur the big players are not playing well. Yet, we collectively must (must!) work towards the good stuff.

As far as I'm aware this is an optimistic look at the options. I commend the makers and I too am biased, I've known of this in the works for years. I am thrilled it's out there and moreover grateful, to cut-through the chat and get the new message to the new scientist who will over time weed out the institutionalized neg-heads. Sorry to sound crass or cruel, I don't mean to. But the gentle whiff of positivity needs to be encouraged and protected. Go make your own documentary and let me know and I'll support you all the way. Meantime, please treat this one as a 'asks the right questions' piece, that let's remember has really make it to the mainstream, as this has! A piece of work to inspire and hopefully to lead by! Congratulations!''

Bias, unsupported with facts, eco-fanatics opinions...and opposition opinions not permitted. The involvement of these high profile celebrities is suspect, too. They've invested in these schemes, so from a perspective, it's an infomercial for their personal wealth.

There's *an identical* "documentary", "A Thirsty World" (2012), that gives the same message. Here we are, eight years after that one, and not one prediction has come to fruition. Actually, some have proven to be the exact opposite of the doom and gloom forecast.

Some nice scenery, if you have a large screen, but otherwise, you can watch with no volume

A number of these technologies are very interesting and promising, but the notion that they're a panacea, that the technology is all there and all that lacks is political will, investment and societal change is frankly false. The energy intensity of many of these solutions is a key problem that was not covered, whilst the prohibitive cost of installing and maintaining others, particularly in developing countries, was not really mentioned. Furthermore, the biggest anthropogenic uses of water, e.g. for irrigation, provide some of the greatest opportunities to reduce water use, so that using marginal sources to reach the very high levels of purity required for drinking may not be required. But innovations in irrigation which dwarf other savings were hardly mentioned at all. It's great to see this massive issue in the popular mainstream, and I credit the creators with achieving that, but a more thoroughly researched sequel would be helpful in due course.
