20100300098 | SOLAR ENERGY POWERED MOLECULAR ENGINE - The sun imparts 174 petawatt per second on the earth, and a large portion of this energy is absorbed by the earth's atmosphere in the form of translational energy for the gaseous molecules, i.e. continuous random motion in the average speed range of 500 meters per second on earth's surface. This invention utilizes a partition with large number of through-holes which all have the characteristic of providing greater cross section for gas molecules to transit from one side to the other than the reverse, thus creating a higher statistical probability for the molecules to move from one side of the partition to the other side. By stacking a number of such partitions to emphasize the direction of movement probability of the gas molecules within a container having two open ends, the number of gas molecules at the end of the stack will be more numerous than at the head, creates a pressure differential, and this can be used to push against the stacks of the partition to provide thrust on the container or to drive a turbine to generate electricity or to perform wide variety of works that are done with internal combustion engine. This invention can use solar energy without photovoltaic conversion or large solar farm to concentrate solar radiation, and it replaces all fossil fuels as the current principle energy source, drastically reducing fossil burning and pollutant generation as well as being a critical means by which to arrest global warming trends. | 12-02-2010 |
