    The evil part, which you have glossed over, is that disobeying a lawful order (which he did, stipulated) should NOT equate to felony assault (which is what he was accused and convicted of). That it does, at least in Michigan, is a woeful misstep in legislation and jurisprudence, and a shameful blot on the soul of every American, including me.

    Up until recently, we the 10% were the ONLY market for these devices. It was our buying that put Apple in the position that made it what it is. Now they're taking "Our" devices and retargeting them at a new market, nine times our size, and ignoring everything we say. Of course we're upset!

    Scroll Lock does something useful to this day in Microsoft Excel.

    But even in DOS 3.3, third-party programs made use of it. FANSI-CONSOLE was a third-party ANSI.SYS replacement that used Scroll Lock for working with text it had captured as it scrolled away. I.e., if you did DIR /S and eight pages of screen got scrolled away before you could read them, hit the Scroll Lock key and then just use PageUp to go back dnd review them. At least that's how I remember it working, my memory is a little fuzzy.

    Your fuel source does not change its mass. The gas in your tank combines with the local air and releases pollutants into the air. Furthermore, it achieves actual movement by turning a wheel which interacts with the ground.

    A spacecraft has no ground to interact with. Rockets produce movement by throwing away their mass. This engine (if it works) would not have to throw away its mass.

    There are other ways to get around without throwing mass. Light sails produce it by interacting with photons that the sun (or a ground laser) throws at them. There's a plasma drive I can't quite remember the name of that interacts with the local magnetic field, in essence pushing on the sun from far away. The "flashlight rocket" (also called a "photon drive") mentioned just below this post throws photons away and achieves movement without losing mass. Ion drives don't count, because they do throw away mass -- tiny amounts of it, but they do.

  25. Feigel's had this bee in his bonnet for years. on How To Build a Quantum Propulsion Machine · · Score: 2, Interesting

    See this item from 2004:

    He started with the fact that electrical and magnetic forces between objects are mediated by photons that flit between them. So an object placed in strong electric and magnetic fields can be considered to be immersed in a sea of these transitory, virtual photons.

    Feigel then showed that the momentum of the virtual photons that pop up inside a vacuum can depend upon the direction in which they are travelling. He concludes that if the electric field points up and the magnetic field points north, for example, then east-heading photons will have a different momentum from west-heading photons.

    So the vacuum acquires a net momentum in one direction — it’s as though the empty space is ‘moving’ in that direction, even though it is empty.

    It is a general principle of physics that momentum is ‘conserved’ — if something moves one way, another thing must move the other way, as a gun recoils when it shoots a bullet. So when the vacuum acquires some momentum from these virtual photons, the object placed within it itself starts to move in the opposite direction.

    Feigel estimates that in an electric field of 100,000 volts per metre and a magnetic field of 17 tesla — both big values, but attainable with current technology — an object as dense as water would move at around 18 centimetres per hour.
