Planting trees to counter carbon emissions won't work

Last I checked superconductors were actually major power hogs due to the cooling requirements. There is also that, if environmental temperatures become high enough that your superconductors no longer conduct that well while you are tossing hundreds to thousands of amperes of current through them the likely result is 'burning powerline' or 'exploded powerline.' Depending.

Actually, no.  Industrial cryogenics has been a thing in use for a while now.  Here's some reading material: http://www.eetimes.com/author.asp?doc_id=1320733

From what I understand, we're close. Almost ungodly so. Like, another ten years or so of R&D close. ...

We've been ten years away from suitable materials for at least the last twenty years.
Call me when there's a laboratory prototype.

So all the breakthroughs we've been having with carbon nanotubes mean nothing to you?
