An exciting development in the development of large scale solar power is an upcoming meeting initiated by reinsurance company Munich Re [LINK]. The giant company is pulling interested parties together to, apparently seriously, discuss possibilities of building a series of large solar thermal plants in northern Africa and the Arabian peninsula and transmitting the power via high-voltage, direct-current (HVDC) cables.
This isn't a new idea, but the fact that such a gigantic company is getting serious about it is a positive direction. It's an expensive proposition, especially because of the HVDC cables, which would run all the way to Europe (at least). But if these companies can actually put up some capital and show that the system works, then I'm sure the idea would spread and governments in North America and Asia would get involved. (Is it all too late? Maybe, but let's try to be a little optimistic today.)
(Okay, the normal spelling of the Egyptian sun god is Ra, but Re is an acceptable alternate spelling [LINK].)
