The Casimir Effect as a source of clean/green energy?

AI Thread Summary
The discussion centers on the potential of the Casimir Effect as a source of clean energy, with the premise that the attractive force between two surfaces at extremely small distances could be harnessed. While the idea suggests that moving surfaces could produce work, the energy density of the Casimir Effect is deemed too low to generate meaningful power. The conversation highlights that the Casimir force is fundamentally linked to well-known intermolecular forces, such as Van der Waals forces, which have been extensively studied. Participants express skepticism about the feasibility of extracting energy from these forces, noting that no serious proposals or literature support this concept. Ultimately, the focus shifts to more practical applications of understanding intermolecular forces, like advancements in dry glues and MEMS technology.

Ok, to begin with my background is in electronics -not physics or chemsitry, so please forgive me if I come across as uninformed on any subject.

My question is in regards to the Casimir Effect and how it may be possible to use this as a source of polution free energy.

My understanding of the Casimir Effect is that is an attractive force that exists between two surfaces at extremley small distances. Similar to the way in which dropping a brick from a height causes work to be done via gravity, two surfaces moving together via the casimir effect would also produce work up until the point they were touching. At this moment no more energy would be released.

Would it be possible that particles suspended in a solution could be induced to move so close together that the casimir effect is triggered? Would this release energy through a chemical reaction- maybe in the form of heat? The by-product would be of a block of material bound together by the Casimir Effect, but since there would be no attempt to pull the particles apart again, energy has been freed up for use.

Clearly, it would take energy to produce a chemical solution such as this, and the triggering of this process would take up energy (if indeed it is at all possible), but might this be a 'green', or at least carbon free, way of producing energy?

We've had this question before so you can search it, but the short answer is the density of the energy is just too low to generate a meaningful amount of power.
 
Russ, thanks for the reply. I will get on the search straight away.
 
Let's put it this way, when you get down to it, the Casimir force is just the Van der Waals/London force. These intermolecular forces have been studied for many many years. Fundamentally there is nothing new here and I have yet to see any serious proposal on how we could extract energy from these forces and I have yet to see a serious admission in literature that such a thing would even be possible. There are far more interesting things that we can do with the ability to more accurately predict the intermolecular forces. For example, dry glues and better modeling of MEMS are promising areas.
 
Thread 'Question about pressure of a liquid'
I am looking at pressure in liquids and I am testing my idea. The vertical tube is 100m, the contraption is filled with water. The vertical tube is very thin(maybe 1mm^2 cross section). The area of the base is ~100m^2. Will he top half be launched in the air if suddenly it cracked?- assuming its light enough. I want to test my idea that if I had a thin long ruber tube that I lifted up, then the pressure at "red lines" will be high and that the $force = pressure * area$ would be massive...
I feel it should be solvable we just need to find a perfect pattern, and there will be a general pattern since the forces acting are based on a single function, so..... you can't actually say it is unsolvable right? Cause imaging 3 bodies actually existed somwhere in this universe then nature isn't gonna wait till we predict it! And yea I have checked in many places that tiny changes cause large changes so it becomes chaos........ but still I just can't accept that it is impossible to solve...
