James Cox developed a timepiece powered by a barometer.
Acknowledging barometric pressure as a source of power
Cox's timepiece is an example of how changing barometric pressure may be used to do useful work [1]
The problem with this piece:
- Material components degrade over time
- Excess energy is wasted not stored
Project Goals
Bringing about an object with the purpose of powering society rather than keeping time using longer lasting materials and a correct vessel for energy storage may be beneficial to society. Benefits may include:
- Freedom from negative aspects associated with many other power sources.
- No polution
- No reshaping of the environment
- No unsightly constructions
- No material spent in process
Drawbacks may include:
- Potential catastrophic changes of weather patterns in the distant future due to removing otherwise naturally balanced energy from the current cycle. Low pressure brings about storm systems. If a device like the one being described was used on a large enough scale to lower atmospheric pressure, locations it operated in could experience storm systems resulting from the lowered pressure.[2]
Things we need to make such a device:
- Appropriately sized and sensitive barometer
- A location that experiences changing atmospheric pressure
- Power storage vessel
Potential questions
- May I somehow better understand how a barometer is constructed?
- Yes. Here. [3]
- What pray tell is a barometer?
- A barometer is a device for measuring levels of atmospheric pressure.[4]
- How is this done?
- To learn how to use a barometer check here. [5]
Design
Merging a barometer similar in design to the one engineered by Cox and those close to him with an appropriate power storage vessel could potentially harness more efficiently than a wind turbine otherwise untapped atmospheric pressure.
Costs
The largest cost of this device would be mercury assuming we are using a mercury barometer like James Cox. Mercury sells for ~~$1950/flask as of 2011 on the free market. [6]
