I did not say that as clearly as I meant to -- it is this latter observable (high power densities) that I have yet to see correlated with low radiation levels in the absence of shielding (water, metal or glass housing, thick substrate, etc.). If it could be shown that high power densities can be obtained in open air without dangerous levels of x-rays, that would clear away any concerns about commoditization. Eric
