ESA Moves Forward on New Electric Engine

museumpeace writes to tell us the ESA is reporting that they have confirmed the principle behind a new space thruster. Plasma Double Layers, first discovered by Australian researchers Christine Charles and Rod Boswell, may help to develop a new electric engine that gives more thrust than traditional engines while still maintaining efficiency. From the article: "In essence, a plasma double layer is the electrostatic equivalent of a waterfall. Just as water molecules pick up energy as they fall between the two different heights, so electrically charged particles pick up energy as they travel through the layers of different electrical properties."

    Would the article submitter PLEASE not call ion engines "traditional thrusters"?

    Now back to thrusting my girlfriend traditionally.

      And given the 134 horsepower someone else figured out for that engine, you'll like, quadruple your horsepower!

    Like, one metal to another??

    How about through a semi-conductor so you can adjust burn rate with a slight bias adjustment? =)

    that there's a 2N3055 Mach V Rev 1.2, mebbe they have an equivilent replacement at rocket shack

    if the potential energy isn't really energy, then where does the energy the water picks up on the way down come from? It has to come from somewhere.

    Maybe it doesn't come from anywhere - maybe it's intelligent falling! /me ducks :o)

    When the ESA develops an engine that can run on magic we'll be sure to give you a call.
