This guy is the kenner. He gives the references he used in building his clock, and reviews of each reference as to how helpful it is. Since his clock works :-) I kinda trust that he's qualified to comment :-) https://www.

The author of the article reports that it is quite mysterious how the circular cheeks and the pendulum work together to compensate for differences in air pressure. And indeed, most clockmakers and virtually all books get it wrong. Convent

Exactly my point. The original comment claimed that the co2 itself was valuable. It is not. What is valuable is that it is concentrated and under pressure.

by rhelz 2y ago
That was exactly my point. What makes the co2 referred valuable is not that it is co2. We literally (not metaphorically, or hyperbolically, but literally ) are surrounded by the stuff every day of our lives. What makes it valuable is t

The application you mention does not rely on the gas being co2 at all. The gas is being used because it is in a high pressure reservoir. It could by any gas. The C02 itself is literally free because it is literally in the atmosphere all

To remove the co2 we put into the atmosphere will always take way more energy than we got out of putting it into the atmosphere in the first place. That is just thermodynamics. To remove all the co2 we put into the atmosphere would take m

Sounds like it comes from the same folks who gave us the phrase "Alpha Male," viz, amateur zoologist tries to draw conclusions about humans from looking at animals, and ends up giving us misleading metaphors.

Fortunately, there is no limit to what we want :-) According to my high-school econ teacher, who defined economics as the art of satisfying our unlimited desires with limited resources.

by rhelz 2y ago
The article has too narrow of definition of what a norm is--since around 1910 or so, we've had to have a more expansive notion of what can be a norm. e.g. the norm for Minkowski's space-time can be negative and does not satisfy th
