If I cleaned one after a few hours operation I'd expect it to be like new.
Have you EVER in your life cleaned out a hot water heater? If I cleaned one after a few hours operation I'd expect it to be like new.
DOH.. Production water heater built on assembly line runs at 170 Fahrenheit. DOH.. prototype E-cat (you keep forgetting the prototype part) runs at significantly greater temps. and have you EVER seen any of Thomas Edison's prototype light bulbs? They don't look anything like what we have off of production lines today..
