| Yes it looks very good. This will have great utility in the Continuous Lighting field. I dont know why it is taking so long to come to market as the test version has been around 10 years.

He believes the first production runs will take place in 2013. Does this mean they have cracked the Godalmighty expensive bit?

| No .... the emitter is an iridium compound ... total annula production is about ten tons, price is about 1000 $ per oz (= 36,000 $ per kilogram). Ed

| Ah, now somebody has found a use for it perhaps the output will rise and the price fall, or the reverse of course...

| Unfortunately not... the price reflects the fact that there is only a gnats pee of iridium in the world! But Dave Carroll has got a very nice proof of concept system Ed

| Whoops! Perhaps a search for an alternative would be the next step? OK, perhaps there isn't one. Great idea, not feasible. So why the claim it's a cheap product? Perhaps they have found an alternative...

| So what are Minolta up to with their research http://www.konicaminolta.com/about/research/oled/creation/index.html http://www.konicaminolta.com/about/research/oled/creation/thin.html http://www.konicaminolta.com/about/research/oled/creation/bend.html http://www.konicaminolta.com/com_message/project/collaboration01/index.html This (or something) will have some serious applications photographically in the future

Constable wrote:Now you are talking! It is my day job! (or part of it!) Well that explained it well. So now we need an iridium alternative. Iridium is one of the least abundant elements in the Earth's crust, having an average mass fraction of 0.001 ppm in crustal rock; gold is 40 times more abundant, platinum is 10 times more abundant, and silver and mercury are 80 times more abundant. Seems like a great research project for some PhD students. So when you come down to Valencia next give me some prior notice as I can meet you there. I guess you must be coming down soon as project initial funding closes at end of 2012.
