If there's not, then Mars will at least have hos. Which is all the more reason to get us there now.

No argument to small time use -- everything works great when there's not a lot of it. Especially people.

I know it doesn't vanish, but it can be relocated -- there's no promise that water taken from one area will be released in such a way that it rejoins the natural flow -- it could easily be locked up in some form, whether that be sewage or storage, or simply bottled and sent elsewhere. Depending on the water's use by whatever desert society is using it, it may never be released back into the system. Unlikely to have a major effect, I know, but I don't think anybody makes the argument that dams don't have an impact on how water flows in an environment. To me, that's what this is. A wind dam. Small now, but...

Maybe this is the paranoid eco-terrorist hippy in me, but I wonder what kind of affect these things would have in already arid desert environments. I imagine that a field of a thousand of these things could seriously affect the local ecosystem, and perhaps the weather in neighboring areas. Though this would be good for Arrakis. Maybe Mars too actually. Now wouldn't that be something. Wouldn't even need to land near the poles to get a little H2O.

Was it obvious and also STRANGE to anyone else that the video was randomly narrated by a robot british lady? I'm impressed because its solid voice work, from a machine. But you can still tell it wasn't a person.

"innovation" or "moving forward." Moving forward is just an all-around useless term for "we didn't do anything really but some time passed." Innovation just gets thrown around too much.
