The future of power? It's only a matter of time.
Using small temperature changes in the encapsulated environment for power, Atmos clocks can run for years without human intervention. Their power source is a hermetically sealed capsule containing a mixture of gas and liquid ethyl chloride, which expands into a chamber as the temperature rises, compressing a spiral spring; with a fall in temperature the gas condenses and the spring slackens. This motion constantly winds the mainspring. A variation in temperature of only one degree in the range between 15 and 30 degrees Celsius is sufficient for two days of operation.
Is this a small glimpse into the future of power generation? The principle seems blindingly simple.
