    Boat motors go forward or reverse using the same shaft, splined to two identical gears facing opposite of each other.
    The power in from above gets locked into only one of the two gears, one will drive the boat forward and the other in reverse, but the engine continues to turn the same direction either way.

    Nicely explained (as usual)!
    It would be a bit of a bugger to print but rather than bristles you could use a spring. Twisted against the spring helix and the spring will try to expand and have a high friction, twist it in the opposite direction and it will just compress the spring until it slips along nicely! I do believe they make ratchet less ratchets this way, with a flat cross section spring.

    I use the right hand rule for right hand threads. Point the thumb of your right hand in the direction you want the fasteners to go and turn it in the direction that your fingers curve to make it go in that direction. For left hand threads, use the left hand in the same manner.

    I think that the 'Mechanical Rectifier' should be incorporated into every piece of playground apparatus that has a to-n-fro movement; such as a see-saw, and a swing (two rods instead of the chains), They both produce strong torque tby way of leverage that could be geared for speed. We get the power while they get to play!....

Very good ; obviously also two bicycle pawls, mounted opposite each other, will do the same job; my father-in-law, Giuseppe Perotti, back in about 1935, applied this system to the wheelchair for the disabled which had a lever which, both by pushing and pulling it, obtained a single movement.

    I'm a bit late, but... I wondered if you could use the "bristle clutch" as part of the drive part of the bevel gear, itself, since it doesn't need, as far as I can see, an actual 'ramp' to have it 'see' a pawl....it looks to e (simple folk that I am), that the angle of the bristles makes a 'pawl', all on its own? This might reduce the maximum torque transmission, but drastically reduces component count??

    Probably a silly question, but since your always up for the challenge of testing new ideas thought i might ask, i wonder if you could do a test to see if the toothbrush heads could be stacked facing a slight angle around a circular disk and see how effective it is as a turbine, to spin the disk when hit by a wind. Similar to your feather turbine idea.

      It's easy clockwise and anticlockwise are right handed and left handed motions, respectively. Point your thumbs along the axis of rotation in the direction of force and you will find your fingers curl in opposite directions, the right hand is clockwise and the left hand is anticlockwise, now if only we had a saying that could dumb down this basic understanding so easily a child could grasp the concept...oh wait.

So, no, It is not intuitive, because right and left are not intuitively designed into Clockwise and CounterClockwise. My hand, naturally rotates in both CW and CCW rotations when holding a screw driver. This is why many people don't understand it until you say Clockwise and Counterclockwise. Maybe you are misconstruing my attempt at revising the childhood Left Loosey as disingenuous? I was serious, I don't think children understand it well, and it seems incomplete. But, anyway...

Easy to learn just point you two thumbs along the axis of rotation facing the direction of force you wish to insert a threaded object towards, unsurprisingly the right hand is clockwise and left hand is anticlockwise and you will find outside of a very select few applications the right handed turn tightens and left handed turn loosens, so easy you could make a children's saying out of it...oh wait.
