Germany's electric u-boat

Another interesting footnote to the War.  I am not just impressed with the reporting here, but also the analysis that many of the so-called 'wonder weapons' cost more than they were worth, and perhaps even hastened the defeat of the nazis by taking up too much in the way of resources.  I wish that the various history and military TV channels would pay more attention to that, instead of their constant braying about how if only the war had gone on another 3 hours or so, the Allies would have been defeated by nuclear orbital jets and whatnot.
