First off, that appears to be a clay brick, not an Ardite ingot on the left.
Second off, this process requires over a million RF. You're not going to get that in an appreciable amount of time off of three water mills. You are also apparently powering it with LV, which is going to be another limiting factor, albeit to recharge rate rather than initial kick, assuming all of the power reserves are capped prior to ignition.
Third off, You are using a Relay on the battery, meaning it is not being included in the power cycle. A Relay only permits you to run lines, it does not connect to anything it happens to be sitting on. This is likely a contributing factor as well.
