Hold on there, OMG! Have you looked around? Microwave tankless is not a new idea, and not the only market presence. See Pulsar's Vulcanus announced 2006 (doesn't seem to have done much - why not?) See also Eemax and Stiebel Eltron, Germany's largest heater manufacturer. Glad you said 'hopefully" because that's still where we're at, and we need to remember it.
