This is a simplified picture of an experiment designed to measure the heim-lorentz force.

We would use a superconducting current loop to create a strong magnetic field.

An insulating disc would be placed above the coil at a location where the magnetic field becomes inhomogeneous.

The disc is then accelerated and when the theoretical conditions are satisfied, gravitophotons will be produced.

Once this occurs the gravitophotons will interact with the protons and neutrons in the disc and the ring will experience a gravitational like force.

When thins occurs we can detect the gravitational field created by the gravitophotons by placing sensitive accelerometers around the ring.

Although large scale experiments are not feasible with existing materials and technology, small scale experiments have been proposed and thus far only one that I know of has been carried out.
