Abstract

Francis tells me that you cannot get sufficient electro motive force with the one [?] machine and that you require two machines in multiple arc. This is a great waste and I think if it is possible to increase your pulleys or the speed of your engine so as to increase the velocity of the Dynamo up to the required electro motive force it would be better to do so.
