Abstract: A user interface enables a user to calibrate the position of a three dimensional model with a real-world environment represented by that model. Using a device's sensor, the device's location and orientation is determined. A video image of the device's environment is displayed on the device's display. The device overlays a representation of an object from a virtual reality model on the video image. The position of the overlaid representation is determined based on the device's location and orientation. In response to user input, the device adjusts a position of the overlaid representation relative to the video image.

Abstract: A photobioreactor assembly, including panel having an array of equal radius, generally parallel, generally vertical and generally transparent tubes, where the tubes have a radius such that for a pre-determined microorganism preferred light intensity level, photosynthesis viable light is available at the center of each tube for an expected maximum culture density for that microorganism, an air supply operationally connected to panel and capable of maintaining a positive pressure within the panel, a water purifier operationally connected to the panel, and a water supply operationally connected to the water purifier. Each respective tube is connected in fluidic communication with each other.
