    New Plasma Propulsion System Generates A Helluva Lot of Thrust

    Our solar system just became a little bit smaller due to a new plasma propulsion concept developed by the US Dept of Energy's
    Principal Research Physicist, Dr. Fatima Ebrahimi. Her new engine uses plasmoids and magnetic fields to generate thrust, making crewed
    missions to distant planets, such as Mars, significantly more
    manageable and less costly. ...

    "My new plasmoid thruster is complementary to existing thruster
    technology," Dr. Ebrahimi told The Debrief. "It is unique in being
    able to deliver high thrust at high and variable exhaust velocity
    (tens to 100s of km/s). It should therefore get unsurpassed gas
    mileage for longer trips (Mars and beyond)." ...

    According to computer simulations run by the Princeton Plasma Physics Laboratory and the National Energy Research Scientific Computing
    Center at the Lawrence Berkeley National Laboratory in Berkeley,
    California, her thruster concept produced exhaust velocities that are
    ten times greater than a traditional ion propulsion system with
    heart-stopping speeds at 100s of kilometers per second. ...

    If used, Dr. Ebrahimi's propulsion system could have astronauts
    reaching the outer planets of our solar system much more quickly.

    Moreover, since the system relies on magnetic fields, the crew could
    adjust their speed by increasing or decreasing the magnetic field
    generated by the engine, thereby altering the plasma exhaust's convergence/re-convergence cycle. ...

    It is impossible for a man to learn what he thinks he already knows.

    Cult members are often given progressively outlandish tests to prove
    their loyalty to the cult leader.

    A Sun morning factoid from The New York Times to mull as you ponder
    the state of America: largely unprosecuted white collar crime costs the
    country $300 to $800 bn a year; by contrast, street-level property
    crime costs $16 bn.
