Optimization of gas-turbine combined cycles for solar energy and alternative-fuel power generation
Article Abstract:
Electricity generated from solar-driven or biomass-fed, combined-cycle power plants is explored in a study which compared mathematical model results with actual combined-cycle power plants. Performance data tallied with analytical predictions of the efficiency of plants with the gas turbine cycle coupled to a steam cycle, with achieved heat-to-electricity conversion efficiency near 50%. However, the solar source gives rise to the problem of decreased solar collector efficiency caused by the hot air temperature driving the gas turbine.

Photocatalytic destruction of organic dyes in aqueous TiO2 suspensions using concentrated simulated and natural solar energy
Article Abstract:
Highly concentrated solar energy, photoassisted by the chemical compund TiO2, is capable of destroying wastes in aqueous solutions caused by organic dyes. These wastes pose a potential environmental hazard as some of them have been shown to be carcinogenic. The effects of simulated solar radiation and concentrated natural radiation on organic wastes are evaluated using a photocatalytic reactor. The dye solution and the TiO2 are placed in the reactor and irradiated with natural or simulated solar radiation.

Guest editorial: solar energy for planet Earth
Article Abstract:
The goal of wireless power transmission and solar and renewable energy systems development is to improve the quality of life while preserving the Earth's ecology and climate. Fossil fuels should be replaced by alternative energy sources to minimize pollution and meet the energy needs of the growing global population. International alliances and strategic partnerships should be organized to ensure that energy development activities do not adversely affect the Earth's climate and ecology.
