## Misc and Totally Random Information

- 1 billion Km = 6.7 AU
- 1 G (Gravity) of acceleration is 980 centimeters per second per second
- Speed of light = 299,792.458 kilometers/second
- 1 light-year = 9,460,528,400,000 kilometers
- 4.184 G-Joules per ton TNT
- Single 100 MJ pulse = 25 Kg TNT
- 1 mm of steel needs 6 KJ/cm
^{2} to melt.
- Steel armor has about 60 KJ/cm
^{3} heat of vaporization.
- Graphit armor: 50 MJ to vaporize 1 Kg. Density about 2.2 g/cm
^{3}.
- Energy required to melt 1 Kg of steel = 289,000 Joules
- 1 gigawatt requires the burning of 0.00297 grams of deuterium – tritium fuel per second.
- Chile’s Atacama desert is the dryest place on Earth. Rainfall is measured in millimeters per decade and some places have not seen rain in hundreds of years. There are places in this desert where no life, not even bacteria, live.
- Matter/anti-matter reactions release 9 X 10
^{16} Joules/Kg. Most of this energy is in the form of pions traveling at high speed.
- Liquid deuterium has a density of 160 Kg/M
^{3} at a temperature of 13.8K.
- 1 Kg of deuterium fuel produces 6.2 X 10
^{14} joules of energy. This assumes a 100% efficient fusion reaction.
- 60 Giga-Joules needed to vaporize 1 cubic meter of iron.
- 1 Kg of anti-matter would generate the equivalent explosion of a 20 Megaton bomb after consideration of the energy loss due to neutrinos.
- Liquid hydrogen has a density of 82 Kg/M
^{3}.
- The power requirement to achieve 10 Km/sec
^{2} acceleration is 50 MW per Kg.
