The Queen has taken delivery of two giant hydroelectric turbines that will help meet the Royal Familyââ¬â¢s attempts to power Windsor Castle using economic sustainable energy.
The 40-tonne Archimedesââ¬â¢ screws were put in place on Wednesday by crane at Romney Weir on the River Thames, just a few miles from her favourite royal residence.
The turbines are made in a factory in Holland at a cost ã700,000. It is estimated that, together with other equipment, they will cost a further ã1 million to install. It is estimated the turbines will reduce carbon dioxide emissions by 790,000 kilos per year.
The turbines, which have the appearance of a screw, were developed by the Ancient Greek mathematician and engineer Archimedes of Syracuse.
He invented the screw to raise low-lying water so it could irrigate land at the top of a slope, but its modern namesake is turned by falling water from the weir. It is connected to a gearbox and generator to produce electricity.
In 2009 plans to power the castle by renewable energy were halted but now Royal advisers believe the time is right embrace renewable energy.
