Thanks for the interesting answers!
What do you think about Finsrud's Perpetuum Mobile ?

Well, its actually pretty simple to build a perpetuum mobile and described already in "Jim Knopf" by Michael Ende (dunno the english title) grin

Finsrud Gravito Magnetic Device:

"He is 'too busy' to answer scientific questions"

... well, that can be expected of any fraud-guy...

Ventilator's device should not work even in ideal condition, regardless of any modification which may be suggested

The fluid can lift the sphere if :

a) Density of fluid > density of sphere

The sphere can enter the tube if :

b) Potential energy of the sphere > work of the pressure of the fluid

claims a) and b) are in conflict

hm... yes, the ball would have to pushed into the water with quite some force at the bottom. didn't think of that. laugh

about finsrud's machine... i guess it's just well machined and quite long running and he sneaks in at night and gives the ball a push or something like that. laugh kind of like a pendulum clock. didn't they just need one push a day too?

Finsrud's Perpetuum Mobile is cool, but not perpetual. The motion is very efficient but driven by magnetic fields, which costed quite some energy to create in the first place.

I once thought of putting a magnet in a coil in space. Give the magnet a swing and it would rotate forever. Free electricity! tongue

If you spin a spoon in space, you will have a perpetuum mobile.

It will not ever stop, if its like in a position like the
intergalactical space.

The earth is also a perpetuum mobile, else it would have fallen into
the sun.

the earth will fall into the sun sooner or later though. laugh so it's not a perpetuum mobile. just very long running.

So, mr Niels Bohr ignored the thermodynamic laws when he proposed his model of atom made od electrons orbiting about the nucleus without losing energy
A little bit unlikely , dont you agree ?

No I don't. The Bohr atom model is able to predict the energy levels of an atom to some extend but it is wrong. Electrons don't move around the core.

Also wanted to say something about that. But it's in vain, because most people won't accept any simple answer and them being not that into this stuff, explaining can be very hard.

Just one thing about the electron thingy; it is far more complex than you may think, and with Bohrs model you just try to model some facts. But keep in mind, that it is only a model, it can be used for certain thing but you can't port the macrocosmos to the microcosmos or the otherway round! It is just a model, a very simple model. Scientists can hardly describe the way of an electron, then there is the thing with not knowing where on the track this electron is. It is all a bit more complex than just sayin, ahh, electrons are perpetuum mobiles wink
And always keep in mind - it is just a model to cover certain physical phenomena - nobody knows what really goes on in these little dimensions. To describe certain things you also have to use different models, and there are way more models than just the one of Bohr.

So enough of it. If you want to know more, look up Heisenberg, Schrödinger & Co wink

The magnetic machine: Well nicely done but a waste of time because it loses energy, of course. It doesn't even run in vacuum, so you got to clean it. What now is the question of energy used to be the question to create gold. The alchemy was born and well - no one ever invented a process to get gold out of cheap components wink

The same applies for the perpetuum mobile - you can spend a lot of time improving new concepts etc. but it would be better to get a real job, because then you got at least a bit of money back wink
