Hey guys,
A good friend has reached out to me about this. Please bear with me, I swear it's not a troll question, I just want to report back with community expertise so I can save his boss from himself.
His boss wants to get into the carwash business, and is intent on devising a more efficient method of heating water. He would like to use an electric motor (I do not know which type) to act as the heating element, running it with it's cooling fins mechanically removed...
I am well aware of how this sounds, and Dave - I'm sorry :C but this is probably the only way I can make him see sense as I've already tried to explain why this is a terrible idea. If 5 to 10 very knowledgeable members can shoot this idea down and kill it then I'm happy for the thread to be closed. Just give me something I can link my friend to to show his boss why this is an awful idea so he'll do what I tell him :C
If it helps, consider it "peer review"... go nuts. Shoot it down.
EDIT:
To clarify, said friend has only just learned the difference between volts and amps, and is currently studying what is roughly equivalent to a BTEC level 2, and is being forced to research stuff by a boss who from what I can understand, doesn't know his arse from his anode.
He's based in Portugal, so the language barrier in explaining WHY this is a terrible idea is possibly being a problem.
