Abstract: Systems and methods for providing a transportation marketplace are provided. A transportation server receives, from a client device of a user, a request for a transportation service. The transportation server determines a set of drivers in response to the request, the set of drivers further being available to provide the transportation service when the request is received. The transportation server provides the set of drivers to the client device, wherein each driver within the set of drivers is selectable by the user of the client device.

Abstract: Methods and apparatus for growing photosynthetic organisms lacking Photosystem II (PSII) function using externally supplied electrons shuttled into the organism using redox mediators to improve photosynthetic output and to produce and recover chemicals of interest. By removing PSII, all PAR photons are funneled toward Photosystem I, thereby significantly increasing the theoretical photon utilization efficiency for CO2 fixation, energy storage and the capacity to synthesize valuable chemicals. Additional genetic modification can be performed to insert or enhance specific metabolic pathways to generate products of commercial interest.

Abstract: A method of managing pre-dedicated funds allows the user to purchase, distribute, and manage gift cards. The method allows companies to provide discounts and promotions to gift card users. A plurality of user accounts is managed by at least one remote server, wherein each user account is associated with a corresponding user personal computer (PC) device. The plurality of user accounts allows each user of the present invention to interact with each other through the at least one remote server in order to manage gift cards. The at least one remote server accepts wireless electronic inputs and returns appropriate electronic outputs. The corresponding PC device is any computer, laptop, smartphone, or other such internet-enabled device that allows the plurality of users to connect to the at least one remote server. This arrangement enables each user to interact with the at least one remote server using the corresponding PC device.

Abstract: A membrane biofilm reactor including a vessel defining a volume is disclosed. The reactor also typically includes a first and second plurality of hollow fiber membranes. Each hollow fiber membrane generally has an outer surface and a lumen, and is located within the volume. The reactor further preferably includes a first and second gas feedstock. The first gas feedstock is provided through a first inlet in fluid communication with the lumens of the first plurality of hollow fiber membranes. The second gas feedstock is provided through a second inlet in fluid communication with the lumens of the second plurality hollow fiber membranes. Finally, the reactor also typically includes a biofilm formed on the outer surface of the hollow fiber membranes and made up of methanotrophs, Methanosarcina acetivorans, or both. The first gas feedstock is preferably different from the second gas feedstock.

Abstract: A microbial electrolysis cell having a brush anode is described. A method of producing products, such as hydrogen, at the cathode of the microbial electrolysis cell is also provided. The microbial electrolysis cell is configured in a cylindrical shape having an anode, cathode and anion exchange membrane all disposed concentrically. A brush anode spirally wound around the outside of the cylindrical microbial electrolysis cell is described. The method may include sparging the anode and/or cathode with air in some cases. In addition, CO2-containing gas may be injected into a cathode chamber to reduce pH is some cases.
