Солнечная электростанция с теплохранилищем

[ny_quant]

From the road between Seville and Cordoba, one can see its central tower lit up like a beacon by 2,600 solar mirrors, each 120 square metres (1,290 square feet), that surround it in an immense 195-hectare (480-acre) circle...

The mechanism is "very easy to explain," he said: the panels reflect the suns rays on to the tower, transmitting energy at an intensity 1,000 times higher than that of the sun's rays reaching the earth.

Energy is stored in a vat filled with molten salts at a temperature of more than 500 degrees C (930 F). Those salts are used to produce steam to turn the turbines and produce electricity...

"The amount of energy we produce a year is equal to the consumption of 30,000 Spanish households," Arias said, an annual saving of 30,000 tonnes of CO2...

The investment cost exceeds 200 million euros ($260 million).

Итого, по $12,000 на household. Еще бы знать, что это в точности означает. Если б я мог купить себе установку, полностью обеспечивающаю мой дом энергией, то отдал бы не только 12К, а и все 25. Не задумываясь.

а почему 12 тыщ-то? вроде 9 примерно, нет?
ну и масштабирование наверное играет роль, тут ведь главное --- отделаться от энергосети.
