I think the concept is sound but it has a long way to go and I do not think there's as much of an environmental benefit as there's purported to be. It's also not viable in countries like your own and others where infrastructure is almost non-existent. That's probably part of the problem, it's not universal so those countries with it sort of bear the brunt of the cost and that cost is high. I'm no expert though.

I think there's a lot of smoke and mirrors and the full picture is not being given as often happens in situations like this...and billionaires become trillionaires.
