So... does it float up in air?
I'm always reminded of Diamond Age with these new materials. It's amazingly close to the stuff in the book (diamond structures which are mostly vacuum and therefore lighter than air). I guess the nano stuctures here are not vacuum tight and contain air within them, so they don't float. But that is something we can improve upon. |

It won't work. HEAT rounds attack on an almost molecular level by drilling through armor with a jet of hot metal. With just spaced layers of aerogel, it wouldn't work because of the pure-element structure of carbon. Sure it insulates by dispersing heat actively, but it doesn't disperse the intense pressure caused by the huge amount of force on a incredibly small area.
Unless you are planning to electrify the graphene plate and use it as piezoelectric armor, then the heat dispersion is useful for helping to disperse the heat energy caused by the transfer of kinetic energy at the point of impact throughout the tank.

Researchers successfully map fountain of youth:
"In collaboration with an international research team, University of Copenhagen researchers have for the first time mapped telomerase, an enzyme which has a kind of rejuvenating effect on normal cell ageing. The findings have just been published in Nature Genetics and are a step forward in the fight against cancer." See: http://www.terradaily.com/reports/Re...youth_999.html |

They also have notions created every time there is a major reactor disaster. Then tend to be seen as much more dangerous and longer lasting problems than other types of power generation plants.
The thing is that problems like that are uncommon for nuclear reactors verse other power plants.

Memory cubes promising a 15x speed boost take a step closer:
"High performance memory cubes took a step closer yesterday after the specification for their architecture was finalised. Prototype versions of the memory cube chips have been demonstrated swapping data with the system some 10 times faster than the DDR3 memory in use today, while consuming 70 per cent less energy per bit." See: http://www.zdnet.com/memory-cubes-pr...er-7000013447/ |
