Probably not in China, since the math with respect to losses works out. The distance from, say, a sunny place like Lanzhou to Shanghai, or even to Guangzhou, is relatively close.

But of course, exporting from Australia to the rest of the world will be problematic. Not sure how that will work? My impression, however, was that they were only trying to get the energy to Singapore? Which should work. It is 3 times longer than what the Chinese are trying to do, and underwater. But again, theoretically, it should work.
