Hi,
The article below states that they made a material that blocks the motion of molecules in only one way but passing the other way is possible. See the article.

This seems to me in contrast with the second law. You can for example make the pressure higher in one compartiment without using energy. Than you use the difference in pressure to produce electricity or motion or whatever. If you would have a closed system the temperature would drop. If you do not have a closed system you can produce energy infinite.
Can somebody explain to me what my mistake is?
