Yep - pretty much sums up my understanding of the state of the development project also. I have never seen mention of the apparent key issue (i.e. power loss due to need to drive the magnetron/magnetrons) in anything from the Company. Talk of cavity geometry (hence h2o flow, etc) optimization I have seen, but this part is not what appears to have been the stumbling block keeping this product concept from reaching market to date (and the patents appear to go back for over 20 years for microwave water heating).
