Zeev Hed - your last paragraph is probably the most important element of our investing future with ISON - from my talk with the company you are partially correct. they are getting out of the business of mass producing for Nuclear industries. they are staying in the business of producing Si 28 for the semicon industry. the Si28 that Eagle-Picher supplies is in the 95% pure range if my memory is correct. the Si28 required by the semicon industry will need to be much purer....on the relm of 99.997% if my memory serves me correct. and, unless i'm completely confused, ISON will be using laser isotope separation licensed from SILEX systems of australia. i own SILX stock as well....missed its big run a few months ago, but SILX would be the ultimate "applications" company for this type of technology. ISON is still a "chemical company" producing high grade products for the medical & semicon industry, the've just decided to get out of the more "commodity environment" of the nuclear energy field. not a bad move all things considered.

Zeev, SInce Si28 is not at all rare and exists as a fairly high % in raw silicon why should the separation cost as much as $75,000 per KG?
It seems to me that there will soon be many people trying to provide this material to industry.
The methods are mature, being laser excitation, Gas centrifuges and diffusion methods with the and they are all low efficiency users of electricity. I am not sure which one is the most efficient. Possibly laser-centrifuge-diffusion is the hierarchy from best to worst. None of them are good, but what are the economics of this extraction process. EP will charge a lot until another producer joins the party. What about the US governments factory going from swords to plowshares and using some of their capacity to do this? Is this forbidden by law?
