The legendary German automaker  Porche has decided the future of the 911 is Hydrogen.  Or maybe alcohol or ammonia.  OOr some kind f potpourri mixture of a basket of fuels.  Together mostly with fuel cells rather than combusttion for the most part, although combustion in some applications.

I'm wondering if they could work up an engine that uses Ammonium Nitrate?  You, know, the stuff we make BOMBS from.  ;D   GREAT energy density!  Problem of course is it's a solid state material.  I'.m thinking perhaps a slurry of nanopparticles, which would add another high tech buzzword into the mix here.  Or maybe ammonium perchlorate.  That's used as a solid rocket propellant and might be great for Private Jets.

Wait.  Forget the  jets and go straight to Private Space Planes!  Unfortunately, the recent 1st test flight by another German compnay crashed on takeoff, but that hasn't deterred them  from going to the next model.  Werner von Braun would not give up.

All we need is to think outside the box, I'm sure we can come up with something.
