Miami, Florida, United States of America.
Various shots of inventor William Skinner in his workshop as he demonstrates a model of his gravity power machine. It has weights that spin round and multiply the power of an 1/8 horsepower motor by 1200 % - enough energy to power a town of 3,500 at a cost of £1 a month. William uses the power of the model to work a 12 foot lathe that cuts ribbons of steel.
