You think that idea is great, have a look at this idea. Even NASA got
involved to help out with this project. These are commercially
available but it seems only for big industry. I envision this idea
being of use in every household across the planet. Can you image
getting steam heat from water in only 3 seconds by nothing more than
mechanical movement? It sounds impossible but do a bit of research
and you will see that this idea is for real.

They say it's a perpetuum mobile, an over-unity machine. If it is, why
don't they use it to produce and sell energy? If it isn't, it is a
totally stupid idea to run a machine just to make heat.

I think that the point was that it was an extremely efficient method
of producing hot water. There is a global requirement for being able
to produce hot water more economically, so it might not seem so stupid
after all.

As for the economy of the thing, consider this: The machine has to be
powered somehow, most likely by a diesel engine. Why not use the diesel
(or some cheaper fuel) directly, to heat the water in a boiler? It is
not at all economical to build an engine that (in the case of a diesel)
converts heat to mechanical movement and then back to heat again. The
engine has to be built and maintained, which costs energy, raw materials
and labour. The same reasoning applies to using an electric motor. It is
just adding an unnecessary step.
