Free Energy Principle

Published on by in Non Profit

@All, There was a man who was known as Hero or Heron of Alexandria (http://en.wikipedia.org/wiki/Hero_of_Alexandria) who demonstrated different principles in mechanical engineering.

One principal that I am most interested in is found in his fountain. And that is if 2 pressure heads are seperate, they can act according to their potential. Simply put, a pressure head over 33 feet (9.8meters) tall will have greater pressure than the atmosphere. Kind of why previous attempts have failed if I am correct. And once an absolute vacuum is established, the vacuum would shift towards the greater mass allowing flow to be established.

And if such is possible, it could move water at a very low cost and it could power a desalination plant that would work on a limited scale of maybe 1,000 gallons a day or a couple of cubic meters of desalinated water. And I think for people who have little, then something like this could make their lives a little easier.

And one last note, if this principle does work as I believe it can, then it could also work as a well pump without need of electricity for those who live in remote locations.

  1. One thing I should have mentioned about this is that a rise in the elevation of the land would create a pressure head. An example of this is going up a hill or mountain. When it comes down the other side, if the pipe is larger, then it could move water great distances. And if the drop in elevation is as an example 3,000 meters, it could both desalinate and move water.

  2. This is a link to a discussion that Petro Alamanso started. In his link, they make known that energy savings of 50% are realized by using a pressure head. The second link is to the article. With what I have suggested, the pressure head's potential could be used in different ways. One way would be to operate a mechanical pump that has a positive displacement. In an impoverished area, it could be helpful. And with a pipe diameter of about 85 cm's, that would be about 1400 kg of force. With a diameter of about 1.7 meters, about 5,600 kg's of force. And with 2 units, one could possibly develop hydroelectric power while other desalinates or purifies water with the RO process. https://water.tallyfox.com/discussions/gravity-driven-treatment-mine-water-slashes-energy-use#comment-form http://sourceable.net/gravity-driven-treatment-mine-water-slashes-energy-use/ I found an online pressure head to watt calculator and if 25% of a 10 meter tall pressure head could flow at about 1.2 meters per second, it might be able to generate about 25 kilowatts of electricity. Myself, I am in a bit of disbelief over this but then 25 kw's translates to about 25 hair dryers or microwave ovens. Still, even that amount of power could be used for an evaporator type water purifier, that is if the location does not have sufficient solar power.

  3. Here are a couple links to pressure head conversion. The 1st requires an input of the height of the pressure head in meters. About half way down is kgf/cm^2. http://www.convert-me.com/en/convert/pressure/mwater.html With the 2nd link, while it is in American units, 32 feet and 9.8 meters are close enough. What this 2nd link shows is that an absolute vacuum can be achieved with such a pressure head. What I am suggesting is a modification of Heron's Fountain where he used pressure, I'll be using vacuum. And with a pressure head of at least 9.8 meters, an absolute vacuum at the top with above atmospheric pressure at it's base should allow the more massive pressure head to establish flow based in it's ability to perform work. http://www.convertunits.com/from/psi/to/foot+of+head metric to feet conversion http://www.csgnetwork.com/csgcvtmeters2ftincalc.html

  4. is there any scientific evidence ti it? it sounds pretty interesting.

    1. Veronika, What I am basing my assumptions on are hydraulic theory and the work of Heron of Alexandria, http://en.wikipedia.org/wiki/Heron_of_alexandria. With his fountain (http://www.youtube.com/watch?v=2VyNln0T6Jc). What people have missed about his fountain is why it works. It uses 2 pressure heads that are separated by space. I used to think it was the volume of water until I did some testing and realized that I was missing something. This is when I realized that it was the height of the pressure head that mattered. You see, with his fountain, the taller pressure head generates slightly more force than the shorter pressure head. Because of this, the taller pressure head fills it's reservoir causing the water to be pumped out of the shorter reservoir. What I am suggesting that is different is using both the force and mass of the pressure head. Why I believe something like this would work is because the space between the 2 pressure heads would be an absolute vacuum. Because of this, the pressure head with more mass/volume should act upon the other pressure head. And this could only happen if it's height is sufficient to generate greater than atmospheric pressure. This latter part is what would allow it to drain and should allow for a continuous flow. A basic test would use pvc pipe that is about 10 cm and 5 cm pvc pipe with a connector pipe less that 10 cm's in length which has a T for filling and capping/plugging the test. Then the drain plug on the larger diameter pipe could be removed first and flow should be established, hopefully. I hope I have been able to better explain things to you.

  5. I thought I would add a link to the basic concept. With an absolute vacuum at the top, the pressure head with more mass is the one that should act on the other pressure head. And with a height of less than 9.8 meters, the pressure at the bottom of the pressure head would be less than atmospheric pressure and could not discharge as a result. And as I mentioned, if this is found to work, I'm sure there are people who could benefit from it as water could be pumped and possibly even desalinated as a mechanical pump with leverage could generate sufficient pressure. Might be a bit old fashioned but when potable water is in short supply, maybe something like this is needed. http://i979.photobucket.com/albums/ae278/bessler_supporter/General%20Engineering/SelfPrimingPump_zpsa39ab079.jpg
