Sikorsky XV-2 stop rotor

Here is a steam engine for a coaxial rotor craft; http://www.unicopter.com/1311.html

Like slowrotor, I suspect that the tip jet is inefficient for forward flight. This is due to the fact that the thruster(s) on the retreating blade(s) are opposing the forward movement of the craft. If it was possible to develop a high-voluming - low-velocity thrust this might do; http://www.unicopter.com/0002.html
