I'd guess that the amount of energy harvestable in the form of sunlight from otherwise unused land far exceeds the amount of energy in the form of coal resources in Australia. But how to ship it to China and India? Set up some high voltage lines? Convert the locally generated electricity to some form of transportable, easily re-convertible embodied energy?

Ship Tessa PowerWalls of course. ;) Hmmmm... actually could be an interesting future business model.

Hydrogen or other synthesized gas is an option, but the transfer losses are pretty brutal (and there aren't massive-scale deployments yet, so unexplored terrain as well)
