    Electric Airliners

    Not yet, but progress is being made.

    Medium sized, 4 engine airliner is being tested with one electric engine in Europe.

    It will be a hybrid passenger plane that would use a single electric turbofan along with three conventional jet engines running on aviation fuel.

    The electric engine would get it's electric power from a turbine within the plane.

    If this system works, a second electric motor could be added.

    Maybe, eventually all engines could be electric?

    It'll be a long time until we have airliners powered by all electric engines, but we're getting there...

    Pretty cool.
    Thanks from johnflesh

    I suppose its possible.

    I don't think there is any greater chance of an electric one failing than a regular one.

    I'm not an engineer however so that's just a guess.

    I couldn't find the reference to the turbine powering the electric engine.. seems to be batteries ?

    If it is a turbine, y question would be, how is that turbine producing electric energy going to be fed ?

    I think it's a great venture, can't wait to see how it turns out.

    As a generalization, elecrical systems are less prone to failure. They are simpler and have fewer moving parts. And dependability of elecronic systems are amazing these days.

    The article I first read was from the AP in my local paper.

    The article I linked was another one online, same subject, I did not find the AP article online.

    I had the same question...What powers the "turbine within the plane"?

    Some sort of petro fuel, maybe.

    But would it be more efficient to run a turbine on petro fuel, that generates electrical power for the engine?

    Interesting concept, needless to say.

    Maybe batteries would be an energy source at some point in the future.

    I would imagine that an electric motor driven turbine would be much cheaper than conventional jet engines.

    There are some very special parts and metallurgy that go into making these big engines.



    I believe they mention somewhere in the doc that the engine is worth seven times it's weight in silver.

    Jets also make an incredible amount of pollution.

    Thx

    Well, IF the turbine would run on Petri fuel... I would question the concept... we know the basic physical laws of conservation of energy... it's neither 'created, nor lost, as its total sum. Yet, using petroleum fuel to create electricity, which then powers the plane engine, rather than using the fuel directly, there HAS to be a lack of consumable energy in that approach, we do not yet have technology that can convert energy from one form into another without losing a part of it to friction , heat energy, etc.

    So, adding a conversion into the process, would necessarily mean we need more petro fuel to power the electric engine, than powering a gas engine right away?

    Solar power would be available as they all fly well above the clouds on every flight.

    Not much for detail but here is a BBC article about at least one effort on this.

    What if its dark out?
