I'm always looking for simpler experiments to test MiHsC. It seems every few months I find a simpler one, so maybe I should just wait till I find one simple enough to do with Lego :) Anyway, one I have recently noticed was by Kish (2007). He took flash drives, weighed them to milligram accuracy and noticed that whenever they were written to, or erased, they lost a bit of weight (about 0.001%) for a short time.
First the caution: what could be happening is that the flash drive is getting hot and moving the air nearby by convection, or water is evaporating from it. Kish (2007) thought not, because the effect did not depend on humidity, or decay with time in the right way. A better experiment would use a vacuum to eliminate these possibilities.
Second the wonder: this could be due to MiHsC. Whenever flash drives are used, the electrons in them are hugely accelerated (flash drives write to memory in one go rather than bit by bit) and you may remember that in MiHsC, whenever there is an acceleration, the inertial mass of everything close by increases slightly. This means that the flash drives, when used, should gain inertial mass by MiHsC and become slightly less sensitive to gravity, ie: they will appear to lose weight, as observed.
This is a simple experiment to do, requiring only flash drives and precision balances, and ideally a vacuum. Without the vacuum it could be done at home. Also unlike the superconductor experiments I've been discussing, the motion of electrons in flash drives should be calculable, and so it should be possible to make a prediction of the weight loss with MiHsC (see McCulloch, 2011) and then test it.
I intend to try this experiment at home (vacuumless) during 2014, but I thought I would mention it here so if anyone out there has the equipment, skill and enthusiasm, you could try it too (the more the merrier). I'd love to see your results: especially estimates of the electron acceleration and a measurement of the drive's weight loss, if any.
