Hey Daniel - instead of straight wide spectrum low IR - why not add a special filter to a tuned resistance heater electrode to get some kind of pseudo coherence? Here is a pretty steep spike at 2 THz:
http://www.insight-product.com/mesh3.htm Low terahertz might work, no? Doubt if they go very high without massive losses. Anyway, mention of the BWO brings to mind another great "missed opportunity" by Randell Mills and BLP. That would be his versions of the gyrotron - which is similar to the BWO and was to be combined with direct conversion of EUV from his hydrogen (hydrino) plasma. He called it the "reverse gyrotron". Supposedly, prototypes were built. Gyrotrons are extremely efficient - and small for their power. It is not clear why Mills gave up on the concept, but Russia owns much of the IP - and maybe he did not want to deal with the Russians. Anyway, newer versions of the gyrotron will reach into low THz. And if HTSC could be added to increase the field strength of the required magnet, who knows? Wow pulses at 50 T. ! http://www.tstnetwork.org/December2009/tst-v2n4-150Powerful.pdf Darn, if I had only managed to guess the numbers on last week's big Lotto prize . well . a new version of this would be on my to-do list. IOW developing this kind of device in the context of a direct converter for Ni-H, similar to the way Mills tried to do with the hydrino - yeah - that would probably eat up 100 million, easy.
