Deuterium-deuterium fusion requires higher temperatures that may be possible in the future. Ultimately, deuterium-deuterium fusion will be better because it is easier to extract deuterium from seawater than to make tritium from lithium. Also, deuterium is not radioactive, and deuterium-deuterium reactions will yield more energy

The human health effects of phthalates are not yet fully known but are being studied by several government agencies, including the Food and Drug Administration, the National Institute of Environmental Health Sciences, and the National Toxicology Program's Center for the Evaluation of Risks to Human Reproduction. 

Di(2-ethylhexyl) phthalate is listed as "reasonably anticipated to be a human carcinogen" in the Twelfth Report on Carcinogens published by the National Toxicology Program. 

hthalates are a group of chemicals used to make plastics more flexible and harder to break.

Once phthalates enter a person's body, they are converted into breakdown products (metabolites) that pass out quickly in urine.

Antimony compounds are used to make flame-proofing materials, paints, ceramic enamels, glass and pottery

Human exposure to antimony can take place

They do not fit through tight spaces and they do not have penetrating power.

Photovoltaic cells are made of special materials called semiconductors such as silicon,

when light strikes the cell, a certain portion of it is absorbed within the semiconductor material. This means that the energy of the absorbed light is transferred to the semiconductor. The energy knocks electrons loose, allowing them to flow freely.
