Abstract: Embodiments of a surface heat exchanger for a vehicle are described. In one embodiment, a surface heat exchanger includes a plurality of fins on a first outer surface The surface heat exchanger is mounted within an interior of a duct of a vehicle. An inlet of the duct is located on a side of the vehicle forward of a rear axle of the vehicle and an outlet of the duct is located rearward of the inlet. The plurality of fins of the surface heat exchanger are exposed to the interior of the duct. The plurality of fins are configured to transfer heat to airflows interacting with the plurality of fins as the airflows pass through the duct.

Abstract: A wind turbine may include a discoidal chassis and at least one vane disposed on the discoidal chassis. The discoidal chassis can rotate about a central axis. The discoidal chassis has a first outermost surface with a pitch angle between the central axis and another axis orthogonal to the central axis. The vane is disposed on the first outermost surface. The vane has a concave surface to assist in rotation of the discoidal chassis about the central axis by harnessing wind energy.

Abstract: The present application relates to a surface treatment composition for inkjet media, including: starch; fluorescence whitening agent selected from the group consisting of nonionic, cationic, and anionic fluorescence whitening agents, and combinations thereof; metallic salt including cation and anion, the cations being selected from monovalent metal ions, multiple valent metal ions, and combinations and derivatives thereof, and the anions being selected from the group consisting of fluoride, chloride, iodide, bromide, nitrate, phosphate, chlorate, acetate, and combinations and derivatives thereof; and chemical chelant. The application also relates to a method of making surface-treated inkjet media, including providing a base stock including cellulose paper and applying a surface treatment composition to the base stock. The application also relates to a paper coated with the surface treatment composition and a system of inkjet printing with surface treated inkjet media.
