The closest modern parallel to their work lies in control engineering and pneumatic instrumentation.

It also has a pneumatic cuff that holds it on, so the more they put themselves under load, the more it attaches.

On application of pressure to the external ear canal with the help of a pneumatic ear speculum the mass could be seen to blanch.

Using a pneumatic trough, he would mix nitrous air with a test sample, over water or mercury, and measure the decrease in volume the principle of eudiometry.

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.

The subsidies are too small and too complicated to inspire capital outlays for expensive specialized equipment, including jack up barges, heavy lift cranes, pneumatic hammers for pounding the foundations into the sea bed, and high strength gearboxes that will not corrode in humid, salty air.
