Methinks I have a crazy plan! How about this; an underground tunnel, approx 1m across, whichwould run from Melbourne, in Oz, under the seabed to California, housing optical fibre cables.
The distance is about 12000km give or take. I guesstimated that tunnelling and optical fibre costs would be around US$2000 per metre. So that figures to be US$24G. I would be interested in any comments on the validity or costingsof such a scheme.
