Yeah – another mad idea…
The “Coriolis effect” is quite simple to understand when you think about it.
Imagine a big wheel balanced on its axis, some place other than at the equator. It is easier to imagine this by exagerrating the size – make the wheel quite large, and the world a few times larger than the wheel in your imagination.
Now, imagine what happens at the north end and the south end as the world turns.You can measure the distance that the ends travel by measuring from either end to the axis of the planet, then multiplying by 2*pi.
You might imagine that balancing a wheel on its axis doesn’t make any difference to how far it travels, but… when the wheel is balanced on its axis, the north end is closer to the axis of the planet than the south end, meaning that the north end actually travels less than the south end!
Of course, the various laws of conservation of momentum, angular velocity, etc, come into play then, and you will find that the wheel will turn slightly to compensate for the difference in distance between the north and south! (I have not tested this, but in my imagination, it works perfectly)
So, my idea is this – attach a generator to the axis of the wheel, and you get free energy! You will of course need to attach some gears to the axis to make the Coriolis motion usable.
Note that the wheel does not need to be flat against the earth – in fact, the most optimal angle would be such that the wheel is perpendicular to the axis of the earth.
