Peaceful Atom Alternative:

Sun, Water and Magma

launchesld's largest solar power plant was launched in the United States, a geothermal one was launched in Iceland, and filters catching nitrogen at shale stations were invented in Estonia.

Industrial geothermal station which prosuces thermal energy from the earth magma was launched in Iceland. This is the first commercial plant of this type, but the second one of its kind. It is situated in a volcanic crater in the north-east of the country. Of course, this place was chosen deliberately, because magma is closer to the Earth's crust there. Turbines that produce energy are installed at the bottom of the crater. They work on magma pressure and high temperature. This station provides a maximum of 36 MW per year; it is two times less than the power generated by burned fuel. However, geothermal station operates all year round and does not depend on weather and fuel supplies.

Meanwhile the USA has already launched the largest solar electric generating system in the Mojave Desert, California. The project costs two billion dollars. According to ITAR –TASS, 350 000 mirrors sized as a garage door are installed in "Ivanpah station" (that's how the generating system is called). Its capacity is 392 gigawatt, which is less than 1% of total energy produced in the United States. But local authorities are going to install several thousand of such objects. "The sunlight reflects from mirrors, heats the water, the vapor rotates the turbine, which generates electricity," - says Jeff Holland, NRG Energy representative.

But our neighbors, the Estonians, decided to install filters on seven boilers of Narva power. The filters will catch nitrogen. Last year one of such filters was installed on one boiler for the experiment, and it turned out that the device twice reduced nitrogen emissions into the environment.

 "Nitrogen filters are needed for old, built in Soviet times slate blocks, where the pulverulent burning technology is used. In the new shale units built in 2005 and at the Auvere the Estonians use circulating fluidized bed combustion technology, which is much cleaner and does not require additional treatment systems ", - says the head of "Narva power plants " Tonu Aas.
