A heat engine includes a first rotatable pulley and a second rotatable pulley spaced from the first rotatable pulley. A shape memory alloy (SMA) element is disposed about respective portions of the pulleys at an SMA pulley ratio. The SMA element includes a first wire, a second wire, and a matrix joining the first wire and the second wire. The first wire and the second wire are in contact with the pulleys, but the matrix is not in contact with the pulleys. A timing cable is disposed about respective portions of the pulleys at a timing pulley ratio, which ...
1. A heat engine, comprising: a first rotatable pulley;a second rotatable pulley spaced from the first rotatable pulley;a shape memory alloy (SMA) element disposed about a portion of the first rotatable pulley at a first radial distance and about a portion of the second rotatable pulley at a second radial distance, the first and second radial distances defining an SMA pulley ratio, wherein the SMA element includes: a first wire;a second wire parallel to the first wire;a matrix joining the first wire and the second wire;wherein the first wire and the seco...
