I have a short news article in the April issue of Physics World about Obayashi Corportions's announcement of plans to build a space elevator by 2050:
"Japanese construction firm unveils ambitious space-elevator vision," Physics World, April 2012, p. 8.
Their design is no surprise to anyone who knows the subject -- it's the basic "Brad Edwards" plan outlined in his book with Eric Westling (discussed in my earlier feature on space elevators in Physics World) -- and Obayashi's plans are largely aspirational. But they are a big, established company with huge financial resources.
In other space elevator news, Michael Laine was recently on The Space Show talking about his resurrection of Liftport and their feasibility studies of a lunar space elevator. That podcast is here.
