Compendium of Propulsion Systems
The way we make a rocket ship move at present is mostly via chemical fuel. The problem with chemical fuel propulsion is that it constitutes most of the space and weight of the ship and it becomes a hassle just getting it off the ground and into orbit. Because of this, other means of propulsion, such as Laser, anti matter, solar sails, Nuclear Fusion, Nuclear Fission, have been recommended. All these and more are discussed in this video.

Radrook Admin: Yes, sooner or later this entire website will disappear with everything posted on it for lack of finding someone to take over when I croak. But it won't be because you folks are refusing to respond. That I can guarantee.

Radrook Admin: That's one reason why I stopped providing long insights into the chess games I play. It's like speaking to the wall.

Radrook Admin: Funny how I can have approx. 400 people at one point browsing, and not one of them wants to give feedback nor participate in any way manner or form. Not even a simple click with a like.

Radrook Admin: Funny how these discussion forums were all the rage once until Twitter and YouTube and other such discussion venues came along.

Radrook Admin: I wish visitors would say something instead of just reading and leaving in silence. Or at the least, at least have the courtesy to rate the material.

Radrook Admin: Reporting physician malpractice might save someone else from getting murdered.

Radrook Admin: Funny how nobody believes you when you describe physician malpractice until it happens to them-isn't it.
