Pneumatic

Back at you, piston head.

This shaft links with a piston.

Put a flame under it, the piston moves up.

That's the piston that was fired out of the floor.

The piston load during compression is three times normal family cars.

Usually this little piston engine turns it but considering that it's lying here completely totaled....

Just as a train is about to go, a young couple rush in and they're just about to close the pneumatic doors.

Take it off the flame and pour water on it, or let it cool down, the piston moves down.

The simplest heat engine, or hot air engine, of all time would be this take a box, a steel canister, with a piston.

Those decisions take place many, many times, and the loop of environment feedback to sensors, agent decision, actuator interaction with the environment and so on is called perception action cycle.

I've looked at focus fusion, I've looked at steam piston fusion, I've looked at D helium 3 and P boron, and all these other kind of things and I'm still going, I'm just not buying it yet.

And if we can actually provide feedback, sensory signals that go back from this robotic, mechanical, computational actuator that is now under the control of the brain, back to the brain, how the brain deals with that, of receiving messages from an artificial piece of machinery.

And we make a mathematical model of those relationships and program them into a tablet computer so that when you take the stylus and go and touch the screen, that voice coil actuator in the white bracket plays vibrations to give you the illusion that you're touching the real surface, just like if you touched, dragged back and forth, on the real canvas.
