An icy stasis capsule designed to keep a living being in a state of deep freeze. If humans ever travel through deep space, even at light speed, it would take years to reach the nearest star. Some people think that cryogenic stasis might be the answer to that problem. We could cross oceans of time and space without aging a second! As far as i know, the freezing part is not impossible with our current level of tech, it's the defrosting part that is a problem...
