    I am wondering...if we can replace petrol engine by electric engine.....how will we replace jet engine with ..electric engine???? For that we need to carry a mini power station with the plane..

    I suppose it may be possible to produce electric powered plane engines. What about nuclear powered planes?

    The big problem is of course energy storage. Petroleum stores something like a 100 times more energy per unit mass than our best lithium batteries.

    A nuclear powered aircraft would probably be quite possible if someone wanted to invest the money and could work through the sometimes irrational fear of anything associated with nukes.

    I don't think so. It would be too heavy and dangerous.

    Nuclear powered can come in a few different forms--not all of them are heavy.

    Nuclear reactors, which are large and heavy but there's several micro-nukes in development which getting down the size of the largest jet engines.

    Then there are the nuclear power that use isotope decay to generate electricity (variously called atomic batteries)-there is no fission. These have been in use for decades by NASA, can be very small and are much more energy dense than standard batteries--most likely with plenty enough to power an aircraft.

    Safety is another issue.
