Engineer: Star Trek's Enterprise ship could be built in 20 years at acost of $1 trillion

"Whether you're a Trekkie or not, you have to admit that there's
some sense of wonder to exploring the stars and trying to find
life on distant planets. Of course, the U.S.S. Enterprise is a
fictional ship, but have you ever put in the thought as to what it
would take to actually build it, and when we could get it done
if we really put in the effort? The man behind the well-researched
site buildtheenterprise.org has, and he's determined that a fully
functional Enterprise is only 20 years away if we put in the effort.

Created by a systems and electrical engineer with 30 years'
experience, the BuildTheEnterprise site sets out a very specific
timeline for the research and construction of such a massive
space-related undertaking. The first nine years are dedicated
to research, component testing, and drawing up a number of
possible blueprints. The following 11 years are dedicated to
development, where components will be manufactured and
launched into space for assembly.
