    The space ship will need to be size of the asteroid with huge engines.

    Remember speculative fiction is not confined to present levels of technology.
    Minaturization of equipment capable of handling vast amounts of power is
    merely the extension of what has been done already.

    Remember Doc Smith's ships with bus bars sagging from the heat?
    I saw sagging bus bars at the Nuclear Power Facilty in Idaho in the
    early 1960s.

    Better conductors and more powerful capacitors and batteries are on the
    drawing boards with exotic new materials.

    It doesn't need great mass and power if it is taking a long time to
    modify the orbit.

    Ah, it's clear you didn't actually read the PDF.

    Lynn's posts fall into two sets: stuff he didn't understand and stuff
    he's actively misrepresenting.

    There's a third class, where he's discussing personal experiences, and
    areas within his field of expertise. Those are quite accurate.
