Gallery: MIT Developing Ionic Wind Thrusters as Efficient Alternative t...

 

A team from MIT is working on developing ionic wind thrusters as an energy-efficient, low-emission alternative to conventional propulsion technologies like jet engines. The new thrusters would use ionic energy, which is created when a current passes between two electrodes. If one electrode is thinner than the other, it creates an air current in the space between them – and if a substantial voltage is applied, the device could produce powerful thrust without the need for fuel or motors.

    Properly neutralized Ion engine doesn’t produce ozone. There is no problem with the ion concept. The problem is in single input large output. They are currently working on micro thrusters. The construction of quantum dot substrate backed bye a capacitance substrate magnetically pulsed without the use of xenon gas will be the way they produce lift eventually. The Ion thrusters will then easily move a craft needing much less thrust as the craft will generate a wake that will not generate drag. Sadly this is 50+ year old tech

    An advanced challenge to realize dreams to built an UFO likes spacecrafts! By combining large size of arc-plate wing model like commonly describe in UFO object, implement this Microwave Thruster to drift laminar airflow over the wing surface to generate lift, and prolong those extra thrust flow directly backward, powered by micronuclear fusion electric generator

    Why not use micro thrusters in front of the blades of an axial flow jet engine? Many small thrusters equals one one big umph (a hybrid ion/jet). Then put a charged wire in front of the charged wing. Reduce skin friction and add lift. I’m not describing the B2, am I?

    The military will be on that in a heartbeat.

    Just a thought off the top of my head, instead of using this for thrust traditionally. If you are ringing the vehicle in a thruster, use it on a hover-craft. Contain the lift by using the skirts to trap the thrust. Most hover-craft are large, and a little ungainly already. Going big wouldn’t be a draw-back. Duct some of the lift to use for foreward thrust. This would negate the problem of a large frontal area.

    I wonder where the electricity to drive such a thruster is supposed to come from?

    I can solve/fix their problem in regards to Thrust Density being limited within Earth’s Atmosphere. No sense in adding more ionic thrusters to the vehicle. More weight = More work required to generate lift and thrust.

    Hi Howard,
    you must recall your last vision “jet engines are the way of the future”,,, well you will become correct!
    😉
    Calm down Chas,, According to the now decades of [failed] research to become useful, ozone has never been a problem,,,
    😉

    @Charli You are right, current jet engines do not produce any polluting emissions.

    And what of the massive amounts of ozone these ion jets would pump into the atmosphere? Sure it’s great when suspended in the stratosphere, but down here where we live it’s a dangerous pollution.
