Thermoelectric Power

Any alternative to generate electric power to reduct a ambiental impact is better to reach ambiental ISO's or mundial recognize. A thermal electric is a green power. No battery (Li-ion/Cadmium/Lead) was used in generation process. Look a little simplified model on picture below.

This plant use a oil to capture high temperatures from sunlight. If use pure water, a temperature is limited to 212ºF (100ºC). All sunlight power was captured on solar fields, heating a oil and transfer thermal energy to water. All water vapor pressurise a specific turbine. Look in next picture a little turbine was manufactured by Ansaldo Energia Italy.

Other alternative to use a thermal power are geysers fields. In Atacama's desert, specific, Tatio's geysers have a greatest power not explored in Chile, South America. Siberia is a very cold and frozen place. But, a large potential in your geysers can be explored in Valley of Geysers, Kamchatka Peninsula. Yellowstone Park (United States, North America) is a beautiful place and high power not explored. Other importants World places can be mentioned: North Island (New Zealand), Iceland (Haukadalur), Beowawe Geyser Field (Nevada USA). A biggest project can be analysed to make a biggest captation of vapor made by volcanic active. Another places around the world have a volcanic active without explosion risk and possible to plant a similar project to generate a green power.

In Brazil, a governamental interest is not big. Petroleum's Industries and Refineries doesn't like this green projects. All financial resources available to this projects are redirected to other programs to indirect benefice to oil. My actual republic president, Ms. Dilma Rousseff, is a little and sweet political image. The parlament make all decisions and laws. I'm so disappointed with my government.
