The best option now, both in order to convince people, and to get to applications and change the world, is to work out how to unambiguously demonstrate quantised inertia in the lab. Since experiments are already underway I have to somehow tread the fine line of talking about how this might be done so that other experimenters can join in, with their own practical insights, but not give the game away for people who are already doing these experiments. So wish me good luck with that!
As most of you know by now, quantised inertia (QI) attributes the property of inertia to a mechanism involving Unruh radiation: a radiation seen only by an accelerating object. The Unruh wavelength seen shortens as acceleration increases. The way to reveal QI in the lab is to accelerate something so fast that the Unruh waves it sees shorten so they can be controlled by our technology. The wavelength of Unruh waves seen by a body with acceleration 'a' is L=8c^2/a, so for an apple falling on someone's head the acceleration is 9.8 m/s^2 and the waves are a light year long. No wonder Newton didn't spot them. Visible Unruh waves would need an acceleration of around 10^24 m/s^2.
Most objects are too heavy to be accelerated that much, but light is an exception, being, well, light! Light going round a desktop fibre-optic loop would produce Unruh waves of a few decimetres length that may be damp-able by metal plates. Just as in the Casimir effect when quantum fields are damped between parallel metal plates, similarly here, a metal plate placed on one side of the light-loop should damp the Unruh field on that side. The other side will be undamped so just as the Casimir plates are pushed together by the loss of the fields between them, so the light-loop here will be pushed to one side, just as a boat is pushed to one side when more water waves hit it from one side than the other (see the references below for discussions).
I have done my usual back-of-the-envelope calculations, and the force you get out will depend on the efficiency of damping, but for complete damping would be of the order F ~ PQ/c where P is the power input, Q is the quality factor of the system constraining the light (eg: the loop), and c is the speed of light. The emdrive is similar to this, but uses contained microwaves instead, and quantised inertia predicts it quite well. There are still many unresolved questions. Can we damp Unruh waves with metal plates? (the agreement between QI and the emdrive data suggests 'yes'). But, let the discussion begin. As for learning a language, the best way to make progress is to try to apply it. Nature may first laugh, but if we pay attention it will eventually co-operate.
