    Harvesting energy from the earth rotation

    People keep thinking this a free energy scheme. It is not. Just imagine a bike wheel spinning on a string. Now add another small wheel to the rim (perpendicular to the big wheel). Spin the big wheel really fast. Now spin the small wheel really fast. The small wheel will start to slow down...

    Harvesting energy from the earth rotation

    According to this research, graphene flakes can spin up to 60,000,000 rpm. http://www.newscientist.com/article/dn19514-levitating-graphene-is-fastestspinning-object-ever.html Couple that with research showing that strained graphene can generate pseudo-magnetic fields in excess of 300 teslas...

    Harvesting energy from the earth rotation

    Here's a businessweek article on these guys in 1995: http://www.businessweek.com/stories/1995-08-27/as-the-world-turns-free-energy

    Harvesting energy from the earth rotation

    Looks like these guys have already put some thought into it: http://www.google.com/patents/US5313850

    Harvesting energy from the earth rotation

    Sure, let me pull out my handy dandy Galaxy Note. Attached is a PNG of the sketch. A shows the gyro on the Earth's equator. In B you see the gyro inside its frame, attached to the gears (I'm no artist). The frame is a vacuum sealed enclosure, using magnets (and/or superconductors) to 1) let...

    Harvesting energy from the earth rotation

    Thanks. Pleasure to be here. The frame would be secured to an object on the earth. It would have a gear system that puts pressure on the gyro as it tries to turn. Would the rotation slow down if the gyro were pushed against its spinning axis?

    Harvesting energy from the earth rotation

    Supposing we had a gyroscope with 100% mechanical efficiency -- say it is in a vacuum chamber, suspended in place by some frame of superconductors. Also suppose this gyroscope has magnets on it, facing outward from the walls of the spinning surface (where the white paint on a car's white-wall...
