of a good reason why this shouldn't work. As we all know a gas is made
up of atoms and these atoms are continuously moving, hence pressure,
temperature etc. etc,
What I am asking is first, is it possible to construct a barrier that
lets atoms through in only one direction? Some sort of nanoscale valve?
I don't think it is possible at the macro scale every scheme I think of
will not work.
If it is possible to construct such a barrier could this barrier be
used to extract work from the systems without any heat sink.
I envisage some sort of barrier which increases the pressure on one
side and decrease it on the other and a turbine working between the
two. Energy would be conserved as the random motion of the particles in
the system as a whole would be decreased.

I can't think of any reason to forbid such as system other than the
fact that it would violate, I believe though correct me if I am wrong,
the second law. It is my contention that the second law comes from
macroscopic systems and thus is not applicable to this system as the
barrier would control the passage of individual atoms.

This problem is annoying me and I look forward to a resolution even if
it is found that what I am saying is absurd.


Here's some background

All really interesting stuff it'll certainly give me something to
ponder over. Thanks.

Anyway has anyone read this stuff on "free energy".

Seems unlikely to me a, bit like cold fusion and I have noted that
even though they are saying they will let independent scientist test
the results they haven't open up their research so labs across the
world to test this, I guess they would claim this is to protect their
invention but it is not usually the way science is done.

I don't get a feeling they are not trying to con anyone but the most
successful con-men never do do they? If they are genuine I would urge
them to let completely independent labs test this, if their research is
corroborated I doubt they will ever be wanting of money.
What does everyone else think?
