Engineers Gone Wild

Tuesday, January 16, 2007 - 16:00

Without doubt, the five thousand-year old Egyptian pyramids are major feats of engineering.  But pointy piles of rock are one thing; quite another is the engineering effort required to combat global warming.  As Earth’s atmosphere continues to be filled with greenhouse emissions, some see geoengineering as the only path to a cooler planet.  But are lofting sulphur into the air or launching a giant sunshade into orbit wise moves, or even ethical ones? 

Also, from cloning to space elevators – why today’s science fiction may be tomorrow’s science fact.  And, would you like to give your love life a boost?  And if so, are you willing to be launched 62 miles straight up for it?  Discover the challenges – technical and otherwise – of sex in space.
