Underwater Dream Machine

Building a submarine without the resources of a big shipyard and using only scavenged or off-the-shelf parts is an unusual idea by any standard. But Peter Robbins has dreamed of submarines all his life, and he is an unusually determined man. Over the course of four years, Robbins staked everything he owned to build his own submarine, the Alicia, in a bid to explore, first-hand, the sunken wrecks of German U-boats. As an engineer, he is fascinated by the precision of U-boat technology; as an entrepreneur, he is intrigued by the prospect of underwater tourism. Assembled from more than 2 million parts, at a cost of $1.5 million, will the Alicia be the success he hoped for? Dive into uncharted waters with NOVA for the maiden voyage of one man's lifelong dream.
