Discussions on global warming and manned space flight, Sahara solar power July 9, 2009

Two interesting discussions to point out today.
First, RealClimate has a brief article about the G8 countries agreeing to try to avoid anything more than two degrees of global warming. The comments vary from hopeful to sceptical and all the way out to cynical.
Second, space scientist Wes Huntress posted an article on The Space Review giving advice about the future of manned space exploration. It’s well worth a read, and the discussion in the comments section is enlightening.
The debate surrounding the future of manned spaceflight is an tricky one, especially as robotic technology gets cheaper and more powerful (see this awesome photo). I would love to see humans land on Mars in my lifetime, but I have a hard time coming up with rational arguments for sending them. Personally, I think we should be looking at the moons of Saturn and Jupiter (specifically Europa, Titan and Enceladus) for signs of life. These would be robotic missions, and I would hate to see them postponed in favour of human missions.
Is human space exploration only considered because of its public appeal, or its space-cowboy, Apollo-era sense of adventure? Is there anything wrong with that? I’d like to see your arguments for human spaceflight if you’ve got any.

There could be some good news coming for supporters of solar power: an article at the Economist says a meeting will take place on July 13 to drum up support for enormous solar power stations to be built in the Sahara. The meeting will be hosted by Munich Re, which has invited 20 other big companies including Siemens and Deutsche Bank.
It would be a hugely expensive project, but would aim to supply %15 of Europe’s power in 2050 as well as most of North Africa’s.

I hadn’t thought about power as a potential export from Africa before. Could generating and exporting power boost the economies of developing nations?

Finally, check out this story about blind people learning to “see” with echolocation! I had no idea!

Fascinating post, especially the echolocation! I don’t think I really have the resolve, but I’m almost tempted to try to pick it up.
