I hope this is for real, but I somehow doubt it, it's probably one of
those neverending development projects. Also, with that little weight
compared to comprable powered engines, unless an aircraft is
specifically designed for this engine just for weight and balance's
sake you'd have to put at least 100 pounds of dead weight on the nose
or move the engine forward a good couple of feet.

Shoot, if that is the only problem, just stack the rotors, and make an
engine with 4 times the power, or whatever is needed for it to weigh the
same as the engine it is replacing. More power is seldom a BIG problem, if
it does not weigh too much.

I hope this engine is for real, and it comes to market. It does look
interesting, and possible, to me.
