Windmill-with-Cows
[National Park Service (In 1854, Daniel Halladay developed the American-type windmill. It was smaller, less expensive and could be shipped and built easily. Its sails were held into the wind by a weight, which would rise slowing to reduce the area of the sails when the wind was too fast. Traditional cloth covered sails were soon replaced with smaller wooden blades.)] Comment ‘You’ve come a long way. I have heard that Texas says they are in the energy business rather oil business. For instance I hear they claim that there was no wind turbine electric energy when Rick Perry became governor by now it is over 30% of electric energy and Texas claims it only costs 60% of the old mainstays of electric energy.’
