What is a metal?

...energy depends on the shell it is in; in general as n increases, the energy of the electron also increases. The energy level occupied by electrons depend on the amount of energy in the system. At high temperatures (such as under a flame), electrons in the metal atoms will absorb heat energy and be promoted to higher energy levels. [Described image] ......

Preparation dyeing and finishing

...energy as the amount needed to heat up smaller amount of water is less. The dye makers have also produced dyes that have higher exhaustion rates (the amount of dye that transfers form the liquor to the fibre) meaning there is less waste and the wash off required (to remove loose dyes) is much lower. This again saves time, water and energy. Finishing the fabric is both...

Food, shelter and re-designing home as a living system

...energy, health and well-being. Multiplying targets existing infrastructure without simply adding more of the same. This may begin with policy design, for example, to introduce incentives for homeowners to retrofit oversized homes into flexible, multi-generation or non-traditional co-housing. Such incentives should increase for integrating food production, biodiversity,...

Dr Benny Peiser - Stories of Change

...energy? BP: Well, that’s a historical question! Thinking back, the first concern about energy really start in my family’s home in the early seventies, my father read The Club of Rome, Limits to Growth, and the fear that we are going to run out of energy was one of the big features of that report and in ’73 it then became almost a reality in Germany and I...

...energy, water, land and labour as inputs, to maintain production and sustain output. Manufacturing also produces many waste products, a large number of which, if not treated carefully, and emitted to the environment, are pollutants and may be hazardous to the local population. An extreme example of the harm that can be done by the lax control of wastes is shown through...
