1% of the land we have now or 1% of what will be left after the ice caps melt?	Motown_Johnny	Jan 2013	#4
But wouldn't that require about 300% of the world's Lanthanides?	Recursion	Jan 2013	#5
Whatever is needed can probably be synthetically created.	randome	Jan 2013	#8
I'm all for a "Man on the Moon" goal for renewable energy	Recursion	Jan 2013	#10
I think that could be done but it would be more like WWII level of societal effort	Fumesucker	Jan 2013	#14
Yeah. I wish things other than imminent death brought that out in people	Recursion	Jan 2013	#15
Or a fake Ozymandious invasion, ala Watchmen.	randome	Jan 2013	#16
No. We cannot "synthetically create" various elements	jberryhill	Jan 2013	#20
i don't think you can synthetically create elements.	ret5hd	Jan 2013	#53
Actually, the moon would be the best place to put solar arrays.	xtraxritical	Jan 2013	#128
Why on earth would you want to use lanthanides?	jberryhill	Jan 2013	#19
Have they fixed that in the last 6 years?	Recursion	Jan 2013	#21
They are used in certain exotic PV's	jberryhill	Jan 2013	#23
Cool, thanks.	Recursion	Jan 2013	#25
And how much usable energy	tama	Jan 2013	#30
Easy.....	paleotn	Jan 2013	#56

20+% is no longer exotic, it's mainstream for SunPower. 44% is exotic.	NYC_SKP	Jan 2013	#36
Yea, I said that's what the report is based on	Confusious	Jan 2013	#38
Got it. Also, I'm confident that the 1% figure is too great.	NYC_SKP	Jan 2013	#45
But if we use 1%	BSlappedInvisibleHan	Jan 2013	#60
We need just 1/6000th the land surface at 100% efficiency.	NYC_SKP	Jan 2013	#64

That may be true, but the water can also be used for other purposes as well.	longship	Jan 2013	#70
Yes, but there's a reason it's only used when there's no other choice	Confusious	Jan 2013	#71
