Building of a space craft...

I was imagining building a space craft in my back yard...;) I was thinking that space crafts are not like cars where if you where to slam on the brakes you would fly forward. Instead you can travel at vast speeds and not be affected inside the space ship. What would I use to propell this machine into space? Space ships do not use fuel like we use on Earth, but instead use........?

I was thinking that the machine could be operated by the beings standing inside and willing it with there energy and minds. The machines need to be propelled, but with what? This video says (above) that they will use lazers. Which is a great idea. Please let me know as I want to start right away on this project. I hope to take a small ship to kepler 22 and start anew....ha ha ha ha......;) Do they use magnets? Stones? I was thinking that they need power and speed, are they using atomic energy in a way that we have not been able to figure out? A neutron can travel and be in two places at once, and travels fast. Are they using that......

Then you would need air, and sustinance. I believe it is possible, but you would need a cloaking device, and the ability to control the craft with the mind. Thank you, ttt
