A Swindon man who built his own electricity-generating windmill has written to King Charles to offer him his own.

Gareth Ross Buddell, of Bishopstone, believes that his windmill based on a 17th-century design - and updated to generate electricity, could interest the eco-conscious monarch.

Having had a response from the King to a previous letter, Gareth is optimistic about getting a reply.

In the letter sent July 31, he wrote: “I am writing to you today with hope and faith for the future. I have built a one-quarter-size approximation of the Bourn Windmill in Cambridgeshire.(Image: Dave Cox)

“This is an open trestle windmill with a difference - this windmill can generate electricity.

“I was amazed by the interest and positive response it created.”

In the letter, he outlined the construction of the mill, mainly from green oak with sails sewn from a charity shop-bought curtain.

He hopes the windmill could power a house and plans to test the structure properly on higher land on the Ridgeway, as it currently does not receive enough wind in his garden.The original Bourn Windmill in Cambridgeshire, of which Gareth's is a scale model (Image: Wikimedia Commons)

He continued: “I think, should a full sizer version be constructed, you may inspire and motivate an entire nation.

“These large windmills could help farmers with their energy bills or perhaps allow for the creation of a small business. The possibilities are endless.

“Sir, I hope you like it and if you, sir, would like one built somewhere I would be more than happy to help in any way that I can.

He concluded: “I have the honour to be, sir, your Majesty’s humble and obedient servant.”

“Last time it took about three months for a response," said Gareth. "I thought that was exceptionally quick considering what the government response is."

A response read that “the King’s motivated”.

Although he said he might not be able to build the windmill for King Charles personally, he would be happy to oversee the construction.

He cannot give the King his own windmill, as he has already promised that to TWIGS community garden.

Gareth has also had interest in his construction from the Mills Archive, which keeps records of traditional and contemporary mills.
