Daily Mail: The UK’s Windsor Castle is going green: Yesterday two 40-ton turbines were lifted into the River Thames. Once installed, they are expected to churn out 300 kW of energy every hour—enough to provide about half the estate’s electricity needs. Resembling giant steel screws, the turbines are based on a 2000-year-old design by Greek mathematician and engineer Archimedes. The project could help further the UK’s goal of obtaining 15% of its energy from renewable sources by 2020. As part of the installation a new fish pass is being installed, which will facilitate the migration of 12 species around the turbines and through that stretch of the river.
