Someone had an idea for a Mirror Drive. All credits to them, you can find it on this forum somewhere.

That would be me, you can see the thread about it here.

This picture shows the concept pretty well though:

Yes, it's exhaust is a stream of mirrors.

I am not sure but I think you get more Delta V using the mirrors as reaction mass and just shoot the mirrors out the back.

When I was a teenager I always wanted to build a finless model rocket with engines mounted way forward on struts, on the principle that the mass and drag of the payload section below would keep it pointed up. After reading this thread, I recalled that concept and decided to try it in KSP. Bear in mind that this is for low-altitude unguided ballistic trajectories.

The first attempt was unsuccessful. Afterwards the testing program switched to un-kerballed vessels with moar struts.

Later 2-engine designs were more successful, culminating in a 4-engine design, which flew well despite starting to flip just before burnout. The fuel tank at the bottom was for ballast

Overall it worked! Now I'll have to start cutting met..., er, gluing cardboard, because hey, it worked in KSP!

"it worked in KSP!" The one phrase you never say to NASA... or anyone making professional rockets, for that matter.

 

Another one of my stupid rocket concepts:

Keep in mind, this was supposed to be BETTER than Apollo.

...I honestly have no idea how this was supposed to be better, at all. I don't even think they have enough Delta-V for those missions.

 

To quote the nerd, "WHAT WERE THEY THINKING!?!!"
