Tesla speculated electricity from thin air was possible – now the question is whether it will be possible to harness it on the scale needed to power our homes
I assume a byproduct of this would be water. So you just make it here instead of as rain.
Natural watering of crops etc could be an issue so irrigation may need to be implemented however
It's not nearly that simple. In the US for example, widespread use of this technology along the coasts (where it's most effective) could mean middle america nearly never gets rain. Unfortunately, that's where the food comes from and it's no simple task to pump water from the coast to the midwest.
