Thanks for the info. I agree that the benefits of FF outweigh the drawbacks of the use of Beryllium. I’ve read a DOE document that refers to a classified safe substitute, but I don’t know if it would be x-ray transparent or of any use otherwise. My question would be whether we would consider a safer material such as Boron or other conductive element, even though it may heat up more and degrade faster. If it’s inexpensive enough to produce and recycle. Say it lasts two years instead of Beryllium’s five years for example, would it be worth it as a substitute, given that it is so much less hazardous, less expensive and makes selling the FF concept so much easier?
Also, there are other useful metal alloys out there that could include cooling components as part of there structure. Are these being considered?
MIL composites
