The only info you need is the fact that Robert said it is so. Now everyone get your pom poms at the ready. Sometime in the next seven years we may get another PR!! JMO,,,2ez
Take a cup of water and heat it for one minute in your microwave oven. Take the cup out and check the water temperature.
Take the same cup of water, put it in a small pan and place it on the cold (like the elements in your water heater) burner of your stove. Turn the burner on for 1 minute. Take the pan off the burner and check the water temperature.
NOW: start with a fresh pan of cold water and place it on the cold burner (assuming that you turned the burner off after the first test). Turn the burner on and time how long it takes to get the water up to the same temperature as the MICROWAVE oven did in 1 minute.
My main question is how can they overcome the power loss in taking electricity and producing microwaves. I am not convienced it will heat water cheaper than existing tankless water heaters.
From all I have managed to research, and the very many related patents that have not to date resulted in product of high efficiency, what you state IS THE key issue. We need to see understandable (i.e. not censored and relevant, intelligibly presented) evidence that the "contemplated" product is tracking to break this technical barrier. JMO
