Multiple passes or chambers makes no difference? That is like saying same car engine will put out same amount of power if they have same cubic inch displacement. We all know each engine shows difference on how it is made far as power (HP). Take a 350 v8 built 25 years ago and look today at same engine world of diffrence now. All because of use of CNC mills for less friction today on parts last longer. Now look at Cyclone engine about to come out, this engine will run on anything that burns even dirty car oil and uses no oil no smog crap needed runs clean.
"No miracle, magic, smoke and mirrors or chicanery can alter the amount of energy that can be transfered into water given a fixed input energy flow"
That gives the context for one of the few accurate statements from WDRP in yesterday's unaudited "filing":
"Substantially reduces risk of scalding injuries to children and elderly"
Talk about making a virtue out of a design flaw!
PS: Yesterday's "filing" was once again prepared by Midland Baring,as right-clicking on the document and selecting "Document Properties" will quickly demonstrate.
Midland Baring was once jointly headed by Jean François Amyot and Andrew Barakett, but this information was altered at the end of October to omit Andrew and once again include one Simon Phaneuf.
So lets say we are going to need a 220volt hook up... okay so thats a little downside for exsisting residential... but chances are people will not get a new water heater until the old one poots out.
new residential not a problem as long as life cost justifies pulling a third 220 volt the other two being dryer and stove.
commercial well they have enough money and if it meets the requirements of their needs they will do it if the cost per use is less..
what is the efficiency of the 220 unit u quoted from home depot? i would say we have a chance of reaching close to 100% efficiency if our magnetrons need to be water cooled which they do the only heat will be lost will be cold pipes to source and from convection from the box if it is not well insulated.
if you still believe in physics you should youtube perendev magnectic motor where a simple reaction gets the motor started and the opposite polled magnets keep the reaction going!
