Mason, I agree with you whole-heartedly. In addition, the one thing that plagues point sources is the ability to collimate the output. A point source spreads it's light into a sphere or portion of a sphere and eminates outward in that shape. For this to be usable, the xrays have to be collected and focused into a beam. This was one of the biggest challenges for the Reagan SDI initiative, and to my knowledge an effective xray reflector has yet to be found. The closest anyone has come is for soft xray (aka EUV) and the multi-layered reflectors they use are extremely difficult to fabricate and are ineffecient (<70% reflective) on their best days. I, like you tend to read through marketing hype. However, if JMAR does come up with a small, collimated point source, it will address one of the key issues with xray. TS
