The used salt hydrate should be chemically stable within a reasonable lifespan, e.g., 15 years. Some salts tend to be oxidized in atmospheric environment which should be avoided for open system; decomposition of salt hydrates to unwanted reactants should be avoided, for instance, MgCl2...
During its lifetime, a typical energy-saving lamp will stop about a tonne of carbon dioxide from entering the atmosphere and pay for itself many times over. [2] So it's good for your pocket and kind to the Earth as well. There are two quite different kinds: CFLs (compact fluorescent ...
content of energy resources (\({E}_{{{\mathrm{RAW}}}\)) by the higher heating value (\({{{\rm{HHV}}}\)), described by Eq.12. We do not assume specific energy requirements for the processing of natural gas and coal, consistent with previous EROI and life-cycle studies63,70. ...

Interestingly, the Swift Current focus group commenced its first day with several cautionary comments about wind power. One juror observed that acres of turbines in California are not working. After this, a discussion surrounding end-of-life and lack of recycling of wind turbine materials ensued. ...
The triboelectric nanogenerator (TENG) is a new type of energy generator first demonstrated in 2012. TENGs have shown potential as power sources for electronic devices and as sensors for detecting mechanical and chemical stimuli. To date, studies on TENG
In physics terms, the world economy is a dissipative structure, just as all plants, animals and ecosystems are. All dissipative structures have finite lifespans, including the world economy. This finding is not well known because academic researchers seem to operate in ivory towers. ...
Procedures related to procurement of energy related equipment need to be developed with high tech budget. Such equipment need to be serviced with regards to its use of energy and its life. 6. Energy analysis reports need to be published in relation the energy recycled back into the system. ...
This transformation is the result of an extremely dynamic pace of technology development which has diffused and penetrated into almost every sphere of human life [11]. One of such spheres, in which there is a gradual displacement of the man–man relationship in favor of the man–technology ...
In both, the three methods confirm an acceptable error for similar forecasting. However, the result fromTable 5demonstrates worse forecasting performance than Case 1. Perhaps the explanation is the number of inputs, or the data is not enough to provide forecasting as well as expected. The error...
