The Energy Construct cost-effectively. The author concludes that wind energy has the greatest potential for near-term expansion. However, smaller-scale use of solar, geothermal, biomass, and ocean sources along with current hydroelectric sources could add up to make a significant contribution. The advantages and disadvantages of each renewable energy option are examined. Nuclear energy is also supported by the author as the only way to produce large amounts of emission-free power. The author pays close attention to the safety of nuclear energy and provides a unique comparison of the safety of energy generation from a number of sources. Fossil energy is then examined with
Hot atom Hot atom In physical chemistry, a hot atom is an atom that has a high kinetic or internal energy. When molecule AB adsorbs on a surface dissociatively, In case 2, B gains a high translational energy from the adsorption energy of A, and hot atom B is generated. For example, the hydrogen molecule, because of its light mass, gets a high translational energy. Such a hot atom does not fly into vacuum but is trapped on the surface, where it diffuses with high energy. Hot atoms are expected to play important roles in catalytic reactions. For example, a reaction of
