Cooling for shuttle
Anyone have a link... graphene outer layer of a rentry surface of a spacecraft for cooling energy needs | |
I saw a video on the net of graphene being burned, well actually a coating that would be applied and burned and it creates a potential voltage? or electricity i dont know.
Now put it on the outside of the hull of a reentering spacecraft (into our atmosphere) and use that energy created to cool the
layer under the graphene. (Solid graphene)?
I think this has been done, i dont know.

Something's definitely wrong with this picture. |

To cool something, you have to move the heat somewhere. Then you have to get rid of the heat. Given the amount of heat involved in re-entry, that would be a LOT of stuff devoted just to heat removal. |

This is one of those things that, even if it could technically be made to work, it's just not remotely practical. With all the added complexity and weight that such a system would add, you're better off sticking with ablative insulation. |

after the ice comets have been moved into Earth orbit, just reshape them around earthbound shuttles. |
