http://www.atmosadam.com/howitworks.html Just googled that. Interesting ^^^ Seems to be small changes in pressure due to atmospheric temperature though, not weight? @technician - I don't really follow your working. Would it be possible to think of it as a simple force of 2000N? and...

true, but the starting and end points of pressure are surely irrelevant? wouldn't it be the relative change in pressure that matters for the equation?

Right. So say if instead of using mercury, it was simply an instrument that stored then released this 2000N of Force over a given time and distance. We can calculate work and power from this. Potentially, could small amounts of energy be extracted from this? (ie, extracting the...

Say you have a giant mercury barometer. Let's suppose that the area exposed to atmospheric pressure is 1 square meter Normal pressure at sea level is 101325 Pa Lets say the variation in 24 hours in atmospheric pressure goes from a low of 100,000 Pa to a high of 102,000 Pa Using...
