## Abstract

A device for converting the kinetic energy of molecules into useful work includes an actuator configured to move within a fluid or gas due to collisions with the molecules of the fluid or gas. The actuator has dimensions that subject it to the Brownian motion of the surrounding molecules. The actuator utilizes objects having multiple surfaces where the different surfaces result in differing coefficients of restitution. The Brownian motion of surrounding molecules produce molecular impacts with the surfaces. Each surface then experiences relative differences in transferred energy from the kinetic collisions. The sum effect of the collisions produces net velocity in a desired direction. The controlled motion can be utilized in a variety of manners to perform work, such as generating electricity or transporting materials.

## Claims

### Claim 1

A device for converting kinetic energy of molecules in a gas or fluid into useful work, the device comprising:
a. at least one actuator that is subject to Brownian motion of the molecules in the gas or fluid, the at least one actuator comprising one or more pairs of a leading face and a trailing face disposed at an angle of more than 180 degrees from the leading face such that the leading face and the trailing face are subjected to collisions with the molecules, the leading face having a first coefficient of restitution with the molecules and the trailing face having a second coefficient of restitution with the molecules that is lower than the first coefficient of restitution;
b. at least one housing configured to contain the gas or fluid within a chamber of the at least one housing, the at least one actuator being disposed substantially within the chamber and further being substantially immersed in the gas or fluid; and
c. a track disposed within the chamber, the actuator being configured to move along the track.

### Claim 2

A device for converting kinetic energy of molecules in a gas or fluid into useful work, the device comprising:
a. at least one actuator that is subject to Brownian motion of the molecules in the gas or fluid, the at least one actuator comprising one or more pairs of a leading face and a trailing face disposed at an angle of more than 180 degrees from the leading face such that the leading face and the trailing face are subjected to collisions with the molecules, the leading face having a first coefficient of restitution with the molecules and the trailing face having a second coefficient of restitution with the molecules that is lower than the first coefficient of restitution; and
b. at least one housing configured to contain the gas or fluid within a chamber of the at least one housing, the at least one actuator being disposed substantially within the chamber and further being substantially immersed in the gas or fluid;
wherein the chamber comprises a channel having a start point and an end point.

### Claim 3 (depends on 2)

The device of claim 2 wherein the at least one housing is configured to allow the at least one actuator to escape the chamber at the end point of the channel.

### Claim 4

A device for converting kinetic energy of molecules in a gas or fluid into useful work, the device comprising at least one actuator that is subject to Brownian motion of the molecules in the gas or fluid,
the at least one actuator comprising one or more pairs of a leading face and a trailing face disposed at an angle of more than 180 degrees from the leading face such that the leading face and the trailing face are subjected to collisions with the molecules,
the leading face having a first coefficient of restitution with the molecules and the trailing face having a second coefficient of restitution with the molecules that is lower than the first coefficient of restitution,
wherein, in each of the one or more pairs, the leading face of the pair substantially comprises a material and the trailing face of the pair substantially comprises the material,
