The easiest way is to take the existing perfect Perpetuum Mobile device and insert some imperfectness into it.

It's the easiest but not the simplest.

Usually, Perpetuum Mobile devices are secret.

There are people argueing even the possibility of such a thing as Perpetuum Mobile.

Ha!

What they know!

Did they see a woman?

You know that saying: don't feed her just let her speak on phone.

Isn't it Perpetuum Mobile?

And she doesn't care even if it's not a mobile phone.

Without any feed, you get a lot of output.

Do you know how much energy you could get if you put a generator to her lips?

And as any perfect device, you can easily stop it - just say to her that you heard that new shoes were brought into the shop near you.

Halts any phone activity on spot.

.

And then you have another perfect Perpetuum Mobile.

She can buy and buy.

No input and a lot of output shoes, shirts, purses, gloves for cycling, hats for diving, lipsticks that on the other side you use as a pen and so on ..

She does it unbelievably easily on the way to her fulfillment*.

(* fulfillment translated from womenish means: fill the wardrobe to full).

And here too, it's easy to stop. Oh, no! The closing of shops is not the stop. Because she knows a lot of other shops that are still opened.

You stop her by saying that her mother is on the phone.

The less time has passed from the last call, the quicker she will catch the phone and move into Perpetuum Mobile regime once more.



So, here we have a perfect Perpetuum Mobile device.

What should we do to turn it into almost perfect?

The simplest, to ask the banker to phone and say that the balance is too low.

This of course won't stop activities but may just slow it for a while.

But then, that was exactly what we wanted to know how to: make an almost perfect Perpetuum Mobile device.

And we succeeded. As usual. When the wife is not near us. (Then it would be HER success, obviously).
