Second, If I do, will I now be able to get useful energy out of it ? "'Wanna chat ? ) 03 : 03, 13 June 2010 ( UTC)

The production of town gas was changed in the late 1950s when Syngas production was developed, a process that converted waste gases from oil refineries to a useful energy product.
33.
A more complex example is the design of animals that have evolved to move mass more efficiently ( to cover more distance per unit of useful energy ) across the landscape.
34.
The designs that happen spontaneously in nature reflect this tendency : they allow entities to flow more easily to measurably move more current farther and faster per unit of useful energy consumed.
35.
In a confined explosion, where the explosive volume is small ( such as occurs in the powder chamber of a firearm ), practically all the heat of explosion is conserved as useful energy.
36.
As long as exergy stands for the useful energy required for an economic activity to be accomplished, it is reasonable to evaluate the cost of the energy on the basis of its exergy content.
37.
Even when the hydrogen for fuel cells is made by stripping it from hydrocarbon fossil fuels, less CO2 is produced than if those fuels were burned to yield the same amount of useful energy.
38.
These materials can be used by host cells, providing a major source of useful energy and nutrients for humans, as well as helping the body to absorb essential dietary minerals such as calcium, magnesium and iron.
39.
A metric for calculating the energy efficiency of storage systems is Energy Storage On Energy Invested ( ESOI ) which is the useful energy used to make the storage system divided into the lifetime energy storage.

The gauge enabled Watt to calculate the work done by the steam while ensuring that its pressure had dropped to zero by the end of the stroke, thereby ensuring that all useful energy had been extracted.
