41. The result is a new kind of actuator, a device that converts electrical energy into mechanical energy . 42. Nanotube actuators might be built in to convert electrical energy to mechanical energy in extraordinarily subtle ways. 43. The purpose of the steam turbine is to convert the heat contained in steam into mechanical energy . 44. Where is that mechanical energy coming from? 45. Hydropower draws mechanical energy from rivers, tides. 46. An alternator converts mechanical energy to electrical energy, whereas a motor converts electrical energy to mechanical energy. 47. Thus mechanical energy is not conserved. 48. "This is the first example of mechanical energy being converted into chemical energy by catalysis, " he says. 49. Every atom incorporates its own peculiar staircase of discrete quantum mechanical energy levels upon which electrons may rest. 50. The viscous dissipation function governs the rate at which mechanical energy of the flow is converted to heat.
