If we apply the logic of the "block box" to the eCat then it is possible to argue it is a hoax even if the output is only dry steam.
This is based on the assumption that it is theoretically possible to use a 600-700 watt resistance heater to transform a water flow of 7 liters/hours (2ml/second) into dry steam if the amount of time the water spends next to the resistance heater is maximised. eg. if the water tube is narrow and forms a tight spiral around the resistance heater.
