The exoskeleton right now is probably best for construction work - both overhead and underground in areas where the system is de-energized. There are issues with using something that probably has a conductive frame in maintenance of live lines. Even if you don't touch the lines, Electro-magnetic fields are going to induce some current and some heating in those conductive areas. The hand...
Shouldn't we be using some of the billions that will be forthcoming from the feds for infrastructure to create a fully resilient grid by putting the vast majority of it underground ?
If there were forthcoming TRILLIONS then this is a great discussion. Underground transmission costs about 6 times the overhead costs in rural areas, and as much as 12xx the cost where there is a population center.
The cost of such a move would be absolutely staggering, as we have thousands and thousands of miles of transmission lines. Just a really bad idea from a cost versus benefit for the country as a whole. From a security standpoint, the vulnerability is greatest at those points where digital protective relays and switching controls exist that can be accessed and controlled remotely by computer....
Larry, from what I understand it all comes down to expense. Though security and visual aesthetics are improved by burying cable, installation and maintenance are more expensive - and dangerous. A careless backhoe operator, for example, can quickly take a distribution grid down and seriously (or fatally) injure himself.
