George Pocock (1774 1843) was an English schoolteacher, the founder of Tent Methodism and an inventor, particularly known for having invented the 'Charvolant,' a kite-drawn carriage. Pocock was interested in kites from an early age, and experimented with pulling loads using kite power, gradually progressing from small stones to planks and large loads. He taught at a school in Prospect Place, Bristol and continued his experiments with his pupils. By 1820 he had determined that in combination they could support considerable weight and began experimenting with man-lifting kites. In 1824, he used a 30-foot (9 m) kite with a chair rig to lift his daughter, Martha (the future mother of cricketer W.G. Grace) over 270 feet (82 m) into the air. Later the same year and continuing to use his family as subjects, he lifted his son to the top of a cliff outside Bristol; his son briefly dismounted from the chair at the top of the 200-foot (60 m) cliff and then concluded the test by releasing a clip on the kite line which allowed him to slide down the line in the chair and return to earth. Having concluded that kites were capable of lifting humans, he turned again to experimenting with them as a way of pulling loads, this time as a method of pulling vehicles. Using kites in various arrangements he determined that a small number of large kites were capable of pulling a carriage with passengers. In 1826, he patented the design of his "Charvolant" buggy. This used two kites on single line 1,500 to 1,800 feet (457 459 m) long to provide enough power to draw along a buggy carrying several passengers at considerable speed, similar to the modern sport of kite buggying. In his book, The Aeropleustic Art or Navigation in the Air by the use of Kites, or Buoyant Sails, Pocock records that it performed at the rate of 20 miles an hour (32 km/h) over considerable distances and that a mile could frequently be covered even over heavy roads in 2¾ minutes. A group of three Charvolants made a trip of 113 miles (182 km) together, and on a run between Bristol and Marlborough one of the buggies sailed past the mail coach, which at the time was the fastest passenger transport.
