When the news broke a couple of days ago on the Yomiuri Online web site that the Obayashi Corporation would be building a Space Elevator by 2050 I was skeptical. Why? Well let's examine the original article. If you use Google's Chrome web browser you have the option of having the article translated. I did that. As well a little history of the company helped.
Obayashi is a huge global construction company and like other Japanese construction companies it projects its business plan with a very long term view. So every now and then they put forward some visionary construction project. It won't get built anytime soon, if ever, but maybe, just maybe someday it will. Unfortunately that's not the case here.
