Watson and Crick's model DNA in the shape of a double helix.
Charles S Watson Sr. invented the Electromagnetically Driven Rotary Motor under a U.S. Patent. Electric energy from a battery is used to shift permanent magnets linearly to create a rotary motion an torque in a rotor set of magnets in-line with a generator that will recharge the battery on the go. Scaled up, this could take the place of the combustion engine and could be used in electric vehicles or home generators.
In1953 scientist Watson and crick discovered that the structure of DNA forms the shape of a double helix ladder.
