Yesterday (December 20th), the second and final Archimedes Screw was lowered into place at Romney Weir on the River Thames by contractors, moving the Windsor Castle project a step closer to completion.
The Environment Agency scheme is designed to harness the power of the river in order to generate electricity for the royal residence.
The 4m diameter screws will generate 300 kilowatts of energy every hour – enough to power half the building - and cut carbon dioxide emissions by 0.8 million kilos per annum.
This makes it the largest hydropower scheme in the south east of England and the build is being handled by Jackson Civil Engineering for Southeast Power Engineering.
Brian Crofton, Jackson Civil Engineering Contracts Director, said: "It is always good to see our industry being involved in new projects like this where we are combining innovation with existing assets on our rivers to create renewable energy for the future."
Although the project is new, the technology behind it was developed thousand of years ago by the Ancient Greek mathematician and engineer Archimedes of Syracuse.
