It's hard to beat single bikes for efficiency; and if uprights are uncomfortable, make them recumbents. But saying the 'world-changing' HPV should be a recumbent tandem trike is an unjustified leap of logic. IMHO.
Do you know the name of this company that makes tandem that can also be a single, leisesturm? Do you have any web links to more info about it? It's a long time since I started this thread, but I don't think I said that I didn't want the passenger to pedal. I do want him to earn his ride!
