The cooling requirement brings up and interesting factor. HOw will the cost of maintaining the cooling system(s) factor into the overall cost? When this is factored in, will this new technology really be more efficient and cost effective than a large copper wire?
What about when, inevitably, the cooling system fails somewhere in the grid? Disaster, or easily remedied maintenance?
It's not that I fear change. In fact, far from it. I believe whole-heartedly in moving forward and exploiting our collective progress in technology. I'm just curious...
