Some high power RADARs use sulpher hexaflouride gas as an insulator in the waveguides, so I'd guess that might be useful in buried HV lines. True, they're easier to repair aboveground, but then less likely to need repair underground. |
Actually, there's plenty of reason for above ground power lines.
Your power bill along with all the other rate payers.
The challenge for large scale moving of power to underground would be to sell it to the rate payers why their bill is going up substantially for the extra cost.

I'd add that the green types wouldn't care too much for large scale use of this either.
