Defkalion was a fraud. See: lenr-canr.org/acrobat/GamberaleLfinaltechn.pdf
So I saw this:
QuoteI show that the experimental protocol used by Defkalion Green Technologies (DGT) is not reliable to demonstrate the production of large amounts of energy with the use of the reactor R5.
How he showed it? By attempt for replication of experimental protocol of DGT? No way - just in the same way, in which the critics of EMDrive now doubt the first peer-reviewed results of NASA: simply by doubting the existing experimental procedures and their published results. No actual replication work has been done.
But which details the experimental protocol of DGT actually contains for example about ignition circuits? Actually none of them, so that these details still remain the industrial secret of Defkalion. The incompleteness of experimental protocol therefore cannot serve as an evidence, that the Defkalion's technology doesn't work - only as the evidence, that it cannot be replicated according to this protocol.
The supporters of academical research like you have it simple: what cannot be replicated simply doesn't work and it doesn't exist at all. But most of industrial research cannot be easily replicated because the lack of published data. This doesn't mean, that these technologies don't actually work - it just means that their results aren't available for public.
