    Jolly good. Thus you have your space weapon. Kneel or fry, white Devils!

    As long as you're not in a hurry. The micronewtons of force will accelerate your ultralight weapon to significant velocities in mere ├Žons, so if that's fast enough for the tactical situation, you're rosy.

    Is it possible for a solar wind powered spaceship to travel faster than the wind up a gravity well ???? ( or something.... )

    No. To do that you need a purchase on something - wheels, a keel, whatever.

    Let me know when the Loonyman Reality Technology Drive is ready and I'll consider investing.

    Possibly about 2 hours and 3 glasses of wine after the Loonykids are asleep...
    ( in my head anyway!!!)

    On a total tangent.... Loonyboy, who is now 10 years old would be disappointed if I didn't pull him into the design chain... He has more skeptical chops than I had until I was in my late 20's! I like to think that I have given the lad a good ground education in bullshit detection, skepticism and rational thinking... But bugger me, his knowledge absorbsion rate is scary, and having constant access to the Internet to answer ( or give him grounds to debate Daddys answers ) is creating something both wonderful and scary at the same time!!!
    ( that said, he has trouble getting his clothing on the right way round... But I feel that is a small price to pay..)
    It kinda feels like watching evolution....

    Posted By: Terry Lingleseems simple to me you just put a light sail on it and sail directly into the solar "wind"
    Sailing into the wind? Into what will you dip your keel and rudder?

    Mere engineering Angus make them large enough and space will work just like the ocean.

    Or dense enough.... But I can imagine a few navigational problems if your rudder is massive enough to plow a wake through space/time.....

    Posted By: loremanI know they're talking torque, it's interesting that there's no average decrease, that's all. In the "radiometer" scenario, can the torque be used to counter the radiation pressure?
    No, for exactly the same reason that angular momentum can't produce linear momentum.

    That's not a black hole. That's a simulation of a black hole. Or if sonoboy's right, a simulation of a simulation of a black hole.

    The map is not the territory. But the territory is "really" a map!
