And one systems and electrical engineer wants us to build the Starship Enterprise by 2032. BuildTheEnterprise, launched last week, is an audacious call to construct a working version of the first-generation USS Enterprise within 20 years. The proposed ship would have an artificial gravity wheel, three ion propulsion engines, and nuclear reactors; it would be able to reach Mars within 90 days. The author, known as "BTE-Dan," isn't an expert in the field, but he's put together a huge wealth of information on current research that could be used to build the ship, how much it might cost, and what would have to be changed or scrapped to turn Star Trek's vision into reality.
