One of the earliest recorded working windmill designs found was invented sometime around 700–900 AD in Persia. [11] [12] This design was the panemone, with vertical lightweight wooden sails attached by horizontal struts to a central vertical shaft. It was first built to pump water and subsequently modified to grind grain as well. [13] [14]
Wind-powered machines used to grind grain and pump water, the windmill and wind pump, were developed in what are now Iran, Afghanistan and Pakistan by the 9th century. [ 1 ] [ 20 ] The first practical windmills were in use in Sistan , a region in Iran and bordering Afghanistan, at least by the 9th century and possibly as early as the mid-to ...
18th-century allegorical print commemorating C.C. van Uitgeest's invention of the saw mill. Cornelis Corneliszoon van Uitgeest or Krelis Lootjes (c. 1550 – c. 1600) was a Dutch windmill owner from Uitgeest who invented the wind-powered sawmill, which made the conversion of log timber into planks 30 times faster than before.

The first wind turbine. William Kamkwamba (born August 5, 1987, in Kasungu, Malawi), is a Malawian inventor, engineer, and author. He gained renown in his country in 2001 when he built a wind turbine to power multiple electrical appliances in his family's house in Wimbe, 23 kilometres (14 mi) east of Kasungu, using blue gum trees, bicycle parts, and materials collected in a local scrapyard.
A flatpack wind turbine invented by a 15-year-old Scottish pupil is to be used to help provide power to communities in Kenya. Douglas Macartney, now 19, designed the turbine for a competition in ...
His invention of the windmill was a crucial key to the old steam trains as back then, they were mainly powered by water, so the water pumping mechanism (the windmill) helped the advance of trains. Versions of this windmill became an iconic part of the rural landscape in the United States, [ 6 ] Argentina, Canada, New Zealand, and South Africa ...
Later an endless chain was used which drove the cap through gearing. In 1745 an English engineer, Edmund Lee, invented the windmill fantail – a little windmill mounted at right angles to the sails, at the rear of the mill, and which turned the cap automatically to bring it into the wind. [15]
