Energy to manufacture

Photosynthesis is a process by which plants use light energy to manufacture carbohydrates from carbon dioxide and water. Because such substances are the primary source of energy for aU organisms, the results of photosynthesis provide energy for life on Earth. 

In summary, materials scientists must consider the implications of their materials choices, from the quantity of energy to manufacture the product, to the performance during its useful life cycle, and Anally to disposal methods. US Environmental Protection Agency (EPA) also provides constraints that the materials scientists must consider in the design of compounds. As most rubber compounds contain approximately 6-20 different materials, not only the materials themselves must be clean and harmless, but any by-products that form during product tire manufacturing must also be harmless to humans and the environment. 

The largest H2 plants that are under constmction have capacities of200 million standard cubic feet per day and operate on natural gas. Hydrogen can be produced from water and high-temperature heat (see below). A 1600-MW(t) reactor would be required to produce the energy to manufacture 200 million standard cubic feet per day—assuming 50% efficient conversion of thermal energy to H2. By the time the AHTR could be deployed, its proposed size [2000+ MW(t)] will match the production capacity requirements of a conventional H2 plant.

DESIGNING WITH PLASTICS AND COMPOSITES A HANDBOOK Energy to Manufacture... 

By itself not particularly strong or durable, aluminum in combination with other metals becomes one of the most versatile materials available. It does take vast amounts of electrical energy to manufacture, however, and presently this involves the production of both carbon dioxide and the sulfur oxides. Alums are astringents and the sources of beautiful crystals. Alumina, the oxide, comes in a variety of polymorphs used as various abrasives and in beautiful, gem-quality minerals. It is also the product of the extremely exothermic thermite reaction. Boron Neutron Capture Therapy (BNCT) offers a potential treatment against brain tumors and other difficult-to-treat carcinomas of the head and neck. Gallium, indium, and thallium compounds do not have many applications.
