Enzmann Mirror focuses a laser to explode the sand spheres creates fusion. A regular mirror will not do. Lasers shatter mirrors. Enzmann Mirror is an invention by Doc E. One mirror expands the laser beam while a second mirror focuses it to fusion temperatures. When focused onto a perfect sphere of quartz sand, an unbelievable amount of energy is released.
A shovel full of sand can power a starship for centuries.
So here, in a ten-minute conversation, Dr. Enzmann has yet another solution to propulsion in space, an alternative to the very limiting chemical propulsion so popular today. Chemical rockets will never reach deep space. Well, unless you are one of those who seem to think the Moon is in deep space. It is not.
