    Sr. Spacecraft Engineer
  1. I would take the stuff used in modern stab vests and make full body armor out of that.
  2. One mans problem is another mans solution.
  3. The problem with using pistons for anything is you run into speed and efficiency limitations. motorjets died for a reason.
  4. It doesn't matter if the fuel is in the middle of the tank. If its pressurized and you open a valve, the helium, along with that fuel will follow the path of least resistance and go into that valve.
  5. Well in the case of the space shuttle, the fuel was pressurized using helium. http://science.ksc.nasa.gov/shuttle/technology/sts-newsref/sts-rcs.html "Pressurized helium gas is the propellent transferring agent." http://history.nasa.gov/afj/aoh/aoh-v1-2-05-rcs.pdf
  6. From plumes on mars to martian invasion, gg 10/10 thread.
  7. I would love to see somebody try to press buttons while wearing the oculus rift.
  8. That still means you would have to know the general location of the enemy, which limits its effectiveness.
  9. Thanks to black body radiation, stealth in space is impossible. Just like warfare today, it will come down to who spots who first. That is barring some crazy technology. Also just a gripe about the whole hiding behind planets and stuff. To hide behind a planet you would already need to know pretty much exactly where the enemy is in order to determine where behind the planet is, and if you know that you would probably be better off blowing him up.
  10. Better than drilling holes in your head to "relieve the pressure"
  11. Last I heard organics is a part of chemistry dealing with carbon molecules, and have almost nothing to do with biological life forms.
  12. How do you escape from a sinking submarine? Most U.S. Navy submarines have two escape routes-called "escape trunks"-that can be used to escape if ever needed. They work like an "air lock" that you may have seen in a movie. The men climb into the escape trunk wearing a special life preserver that has a hood on it to provide a bubble of air to breathe. When the lower hatch is shut, the trunk is filled with water and pressurized to sea pressure. The trunk's outside hatch opens, and the men float to the surface. How are people rescued from a sunken submarine? There are systems built into the submarine to assist the crew to escape safely, if required. The Navy has also developed two rescue submarines called Deep Submersible Rescue Vehicles (DSRV). You may have seen them in the movies, Hunt for Red October, or Gray Lady Down. They drive up to the damaged submarine, mate to the escape hatch and take the crew to safety. New technologies are planned for incorporation into the next generation rescue system called the "Submarine Rescue Diving and Recompression System." http://www.navy.mil/navydata/cno/n87/faq.html
  13. Modern nuclear submarines actually have several things designed for human comfort, including hot tubs!, I would like to see a space station with hot tubs. "SSBNs are so large that some people even run marathons by running around the perimeter of the missile compartment many thousands of times!" http://www.navy.mil/navydata/cno/n87/faq.html
