So, 205 move a day is not bad? More to follow I hope, what is your take on this NUKE post I just posted at NEWTECHMINING talk board at RB:
HOLY COW from NUKE BOARD, or is it ATLI news related , a JT Pick, LOL:

Clean burn
By Andy Coghlan
a simple metallic filter might cure one of the oil industry's biggest environmental headaches by cheaply removing sulphur and heavy metals from oil. The filter could open up huge reserves of oil in South America, China and the former Soviet Union that have previously been far too dirty to tap.
The existing method for removing sulphur is expensive. The oil has to be heated to 700 °C at 70 times atmospheric pressure. The metallic filter works at room temperature and atmospheric pressure. "Instead of spending billions of dollars looking for more oil, you could take what's already there and use it," says Roger Duffield, the entrepreneur developing the technology. He has founded Klinair Environmental Technologies of Dublin to market the filter.
"The potential for sweetening sour oil is huge," says Roger Lane-Nott of the Centre for Marine and Petroleum Technology, a research monitoring body funded by the oil and gas multinationals that is helping to promote the technology.
Sulphur in fuel cuts the effectiveness of cars' catalytic converters because it poisons the catalyst. Many countries, including those of the European Union, are considering tougher limits on the sulphur content of fuel to curb this problem.
The filter is based on a substance called an intermetallic--a blend of metals combined in very precise proportions. Unlike alloys, in which the metal atoms are distributed at random, intermetallics consist of discrete crystals, each with a highly defined combination of atoms.
Duffield is keeping the identity of the two metals secret, but he says both are cheap. After a mixture of the metals is heated to 500 °C, it is fired through a nozzle to form a fine, whitish-grey powder. This powder is then deposited onto an inert substrate such as carbon fibre to create a granular surface that resembles a ceramic.
Emulsions of oil and water, like those typically found in crude oil, separate on contact with the coating because it not only adsorbs sulphur and heavy metals but also the surfactants that maintain the emulsion. Duffield found that this stopped the intermetallic working. But he has now discovered that a small voltage keeps the sodium and calcium surfactants in solution. This preserves the emulsion and allows the intermetallic to carry on extracting sulphur and metals from the oil. The contaminants can later be washed off the filter with solvents such as alkalis or methanol.
By altering the voltage across the intermetallic, the extraction process can be fine-tuned to pluck out individual compounds or families of compounds.
The filter is being developed by Teh Fu Yen, a specialist in the removal of impurities from petroleum at the University of Southern California in Los Angeles. Yen is extremely impressed by the technology. "When I first took this research on, I was amazed," he says.
A pilot version of the filter is due to be tested before the end of this year at the Irish State Refinery Company in Cork. "Present technologies for removing sulphur are expensive, typically around $5 per tonne of oil treated, so there's a big prize if anyone can do it more cheaply," says Neasan O'Shea, chief technical adviser at the Cork refinery. "This technology is different and looks promising."

I remember this great news hitting national headlines - NOT! Boy, he must be a great marketer. Sorry, couldn't resist. I guess we'l have to hope for the best.
