Bullets to Rockets – “Non Scientist’s” scientific thinking

Thinking about rockets as bullets.  A gun barrel is designed to spin a bullet as its more accurate then in it was just fired out.  Wondering about the concept of spinning a rocket,  does it make it more efficient as it travels to spin a bullet and ergo would it be better to spin a rocket?

Spinning a rocket would not be good for the crew but I was thinking conceptually,  not thinking of the engineering behind it all.  How about spinning the outside of the rocket but maintaining a stable crew compartment that did not spin.  Probably some kind of gyroscopic crew compartment to maintain its stability would work.

I Googled spinning rockets and found a PDF https://www.apogeerockets.com/education/downloads/Newsletter228.pdf which talked about why spinning rockets fly straighter,  the image on the front made be think,  the tail fins in that are shown on that rocket would be inefficient and cause resistance in a spinning rocket and would have to be angled to match the rate of spin.  Possibly adjustable fins on a rocket could be used to adjust rate of spin much like flaps are used in a plane.

Science Musings from a Non Scientist – TFTD 30th Aug 2017

I know “not much” about science but maybe science needs people who think outside of the restrictions governed by the laws of physics.

If you could make an object with a force of gravity that was small. Encapsulate it. Put things in an orbit around it and somehow tap into its energy have you not just created a gravity piston or generator. ??

If you create something with gravity of at least 1.1. Earth being 1 and made it portable do you not have something that is an antigravity drive?

And if leaving earth orbit takes so much energy going straight up why not slingshot around Earth. But then again you would need a craft so fast to take advantage of the earths elasticity in the gravitational field it would be too difficult to capitalize on it.

I then thought a bit about centrifugal force to generate artificial gravity as in https://en.m.wikipedia.org/wiki/Artificial_gravity and using it in conjunction with nanoscopic pressure cells that can be used to generate energy through application of pressure.

Can you not spin a hollow tube with weights in it and nanoscopic pressure cells and generate electricity and would that be more efficient then the current wind turbine generating technology we used today?
