And what country can preserve its liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance? Let them take arms. The remedy is to set them right as to facts, pardon and pacify them. What signify a few lives lost in a century or two? The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.

Probably generates as much electricity as a current Westinghouse WGen9500DF.ReplyDelete
"The first electricity-generating wind turbine was invented in 1888 in Cleveland, Ohio by Charles F. Brush. The turbine's diameter was 17 meters (50 feet), it had 144 rotor blades made of cedar wood, and it generated about 12 kilowatts (kW) of power."
meanwhile, down the road a couple of clever lads were inventing heavier than air flight in their bicycle shop.ReplyDelete
In 1878 when the family lived in Cedar Rapids, Iowa, their father brought home a toy helicopter for his two younger sons. The device was based on an invention of French aeronautical pioneer Alphonse Pénaud. Made of paper, bamboo and cork with a rubber band to twirl its rotor, it was about 1 ft (30 cm) long. Wilbur and Orville played with it until it broke, and then built their own. In later years, they pointed to their experience with the toy as the spark of their interest in flying.ReplyDelete
