Storyline concept

I need to dump this concept somewhere:

As a method for international star travel, in an age where human science has conquered star faring propulsion technologies but not the human lifespan, nor the ability to store a computerized mind more powerfull than a cat in anything smaller than the volume of an elephant, humans develop a mechanized shell with the ability to grow a humanoid host.

Designed as a cyborg, the shell is 2 stories tall, with a life support chamber within that can grow and support a human being. If the human is ever killed, dies of old age, or leaves the shell, or is terminated, a new one can be grown to serve as host based on a storage bank of zygote clones with identical DNA to the former host. The shell nurtures and raises the human within the chamber, utilizing hormonal growth regulations, optimized sleep cycle regulation, and databanks containing interactive virtual reality recordings that allows the human to be raised, and eventually come to understand it's position, based on the lifes of the previous hosts.

Any space travel accross long distances means the death, rebirth, and re-raising of the host upon closing to the destination, effectively leaving the shell as a whole immortal, but always alone, and suffering from varying degrees of amnesia depending upon it's development.

I'm not quite sure what this concept means, but I thought it was cool when I came up with it....
