  • Patent number: 12570553
    Abstract: A groundwater remediation system includes a capillary media supported and positioned such that it is partially submerged into a groundwater source to be remediated. Groundwater is drawn into the submerged portion of the capillary media and further into the non-submerged portion of the capillary material via natural capillary action. As the water evaporates from the non-submerged portion of the capillary media, the dissolved solids within the water precipitate onto the media leaving the precipitated solids for reclamation or disposal and allowing the cleaned water vapor to disperse into the ambient air. In some embodiments, heat may be added to the media, water, or air to accelerate the evaporative process.

  • Patent number: 11027752
    Abstract: A railway facility with high throughput loop track includes a series of adjacent parallel staging tracks connected to a main line to receive and depart trains, arranged in a path so that trains transverse around the railway facility. A balloon loop track, which includes a loading or unloading facility, is connected to the staging tracks loops and reverses the direction of the train so that upon completion of loading or unloading a train can depart or be re-staged without requiring repositioning or turning of locomotives. Staging tracks are included for staging both arriving and departing trains. In alternative embodiments transload tracks and at-grade access roads allow storage and retrieval of cargo to interior space within the staging tracks, and an escape track allows expedited exit of trains from the balloon loop track.
