From Brownian Motors to Maxwell's Demon

[andreas_varesi]

With Brownian Motors scientists want to utilize the chaotic thermal movement of particles within ambient temperature.
A ratchet mechanism could be the key to free energy (for a demo look at: http://monet.physik.unibas.ch/~elmer/bm/).
Very interesting is that Brownian Motors are well accepted by the scientific community. Unlike other free energy topics there are some articles on Brownian Motors even at leading magazines like "Annalen der Physik" (http://www.physik.uni-augsburg.de/theo1/hanggi/Papers/376.pdf) or "Applied Physics" (http://www.physik.uni-augsburg.de/theo1/hanggi/Papers/287.pdf).

Although the authors always state that there is no violation of the 2nd law because there is energy needed to realize the ratchet mechanism there are some facts that are not consistent to the 2nd law: Unlike traditional motors Brownian Motors don't need a net force, nor a concentration or temperature gradient for a directed motion.

As Brownian Motors only indirectly make use of thermal movement of gas or liquid molecules their efficiency must be very low. For a significant higher efficiency we would need a kind of Maxwell's Demon which is directly using the movement of gas molecules. I believe nanotechnology is the key for this Maxwell's Demon.

What is your opinion?

I expect that an array of billions of nano nozzles each built on a scale of tens of nanometers facing the same way between two chambers would aggregate net Brownian movement. Each nozzle has a installed structure which imposes a preferred direction of travel on its volume of fluid (gas or liquid) A nozzle is a segment of a conical hollow with a small opening on one side that tapers to a large opening on the other side. Fluid tends to bounce off the interior wall and leave on the side of the large opening. This is a mechanical analogue of the diode array. It can be used to separate fluid mixtures or provide hydraulic power. There are ways to mass etch tapering pores.

I have published this concept so that everyone can use it without excluding others.

Hello Charlie Brown,

your concept sounds quite plausible. Do you have a link to your publication or are there already any prototypes available?

Thank you in advance.

I think we already have something simular with the saltwater cells.
As there is also lots of micro dust carbon in these cells, these cells also rectify
some wavelength, probably mostly X-Rays.

Fission track etching is one way to make straight pores of uniform size. Etchants that avoid entering the pores may be one way to flare the pores as they exit to the outer surface. Everyone is so well connected nowdays that its easier for inventors to find prototype experts than do things themselves. Sometimes people can grasp ideas as gestalts with little need of elaboration. We need to find a nanomachine shop that gets the idea of nanonozzles and fills in the details of execution. I expressed the idea of nanonozzle fluidic brownian pumps to Robert G. Hockeday Jr. in Albeqerque NM many years ago. He referred me to fission track etching. He said he would try to make a prototype. He got busy with domestic life with his wife, Mary who is also a Physicist.

Aloha, Charlie
