  2. Paint sealant - Wikipedia

    en.wikipedia.org/wiki/Paint_sealant

    Paint sealant works by filling into the pores and irregular surface of the body thereby creating a smooth finish on top. The way it helps is it denies a sticking surface to foreign substance and they come off the car easily without further damaging the car surface.

  3. Ion thruster - Wikipedia

    en.wikipedia.org/wiki/Ion_thruster

    An ion thruster, ion drive, or ion engine is a form of electric propulsion used for spacecraft propulsion. An ion thruster creates a cloud of positive ions from a neutral gas by ionizing it to extract some electrons from its atoms. The ions are then accelerated using electricity to create thrust.

    Current EHD thrusters are far less efficient than conventional engines. [15] An MIT researcher noted that ion thrusters have the potential to be far more efficient than conventional jet engines. [16] Unlike pure ion thruster rockets, the electrohydrodynamic principle does not apply in the vacuum of space. [17]

    B. Wilson in 1750 [2] demonstrated the recoil force associated to the same corona discharge and precursor to the ion thruster was the corona discharge pinwheel. [3] The corona discharge from the freely rotating pinwheel arm with ends bent to sharp points [4] [5] gives the air a space charge, which repels the point because the polarity is the same for the point and the air.

    en.wikipedia.org/wiki/Seam_sealant

    Seam sealing was already performed manually successfully for preventing perforation corrosion in the 1980s. [1] Today used in the OEM automotive industry primarily for the purpose of seals against air leaks and to waterproof sheetmetal overlaps that occur in the assembly of a vehicle.

  8. Gridded ion thruster - Wikipedia

    en.wikipedia.org/wiki/Gridded_ion_thruster

    The gridded ion thruster is a common design for ion thrusters, a highly efficient low-thrust spacecraft propulsion method running on electrical power by using high-voltage grid electrodes to accelerate ions with electrostatic forces.

  9. Magnetohydrodynamic drive - Wikipedia

    en.wikipedia.org/wiki/Magnetohydrodynamic_drive

    Illustration of the right-hand rule for the Lorentz force, cross product of an electric current with a magnetic field. The working principle involves the acceleration of an electrically conductive fluid (which can be a liquid or an ionized gas called a plasma) by the Lorentz force, resulting from the cross product of an electric current (motion of charge carriers accelerated by an electric ...
