[Spaceships] Anti-Lithium for Drives Does this work?
I recently stumbled over this article:
http://hardmaths.blogspot.co.at/2017...n-options.html Go to the bottom of the article to Option: Anti-Lithium (TL11). This is an idea for a stronger version of antimatter drives such as the antimatter thermal rocket. An antimatter thermal rocket gets much better delta-V per tank (10.8 mps) with anti-lithium. This kind of drive combines good acceleration with good delta-V. A spacecraft could lift off from a planet (especially if it is winged and has a drive with the air-ram option that gives some free delta-V) and fly right to another planet. The old science fiction staple, the interplanetary spaceship that can land on a planet, appears possible this way. So I wonder how hard the science behind drives with anti-lithium is. Of course, the idea of using anti-lithium (or just a bigger load of anti-hydrogen) seems straightforward enough, but I wonder what stress this puts on the engine and how much radiation it produces. Can anybody with a background in science say if this makes sense? Thanks in advance! |
