Coinciding with the start of the Cold War back in the 1940s, Atomic Age design looked to the future, full of speculation, wonder and, yes, fear about technology, space and the role of mankind in all of this. The end result was a visually inventive movement that combined elements of mid...
Cohesive FG domains assemble into a condensed phase forming the selective permeability barrier of nuclear pore complexes. Nanoscopic insight into fundamental cohesive interactions has long been hampered by the sequence heterogeneity of native FG domains. We overcome this challenge by utilizing an engineered...
A launch laser or mass driver powerful enough to boost huge masses into orbit can smash a combat starship like a sledge-hammer hitting a cockaroach. If there is a planetary disaster, spaceports will suddenly be thrust into the role of operational center. After all, it will be the source ...
This concept involves a nuclear means of producing and focusing a high-density, extremely high-velocity gas (Nuclear Howitzer) or, by means of a second interaction, a mass of high velocity, solid pellets (CASABA) into an angle of about 2°-4°. The desired effect of this concept is a ...
One FH has a liftoff mass of 1,462,836 kilograms. It is assumed that one FH can put 53,000 kilograms into LEO, 17,216 kilograms into either a lunar or Earth-Moon L1 (EML1) orbit, and 5,739 kilograms onto the lunar surface. Mass doesn’t necessarily have to be lifted directly ...
Golden-aged science fiction authors E.E."Doc" Smith and John W. Campbell jr. noted this and postulated space-opera science that required elements in the middle of the periodic table for direct conversion ofallthe mass into energy. In Doc Smith's"Skylark"series the element was copper (63 ...
Alpha : (kg/kW) power plant mass in kilograms divided by kilowatts of power. So if a solar power array had an alpha of 90, and you needed 150 kilowatts of output, the array would mass 90 * 150 = 13,500 kg or 13.5 metric tons Specific Power : (W/kg) watts of power divided by...
Galactic a galaxy, most or all of its stars, up to all mass associated with it. Universal the entire universe, all or most galaxies within it, or all major galaxy filaments or equivalent highest-level structures. Multiversal multiple universes, or whatever that exists outside of the setting'...
After a certain mission duration, it will be cheaper (in terms of mass) to use a CELSS instead of transporting consumables. With a primitive CELSS this happens at about 145 days, increasing the efficiency will bring the break-even duration point lower. The mass of the CELSS is constant rega...
Impact rounds come in a variety of shapes, sizes and compositions for varying roles. Impact rounds are made out of materials of much lower density than the lead normally used in bullets, are larger, and are fired at lower velocities. Rounds are designed with low mass, moderate velocity, and...
