Abstract: Using radial air bearings to support the rotor at the perimeter, vertical axis wind turbines (VAWTs) are less expensive and faster to build. With just one moving part, the rotor, direct-drive generation may be employed to eliminate the drive line, gear box, and bearings at the generator.

A delivery device (1) provides a stream comprising a substantially vaporized precursor and a carrier gas from a location remote from the radiant energy generated by the IR burner, and (2) causes the stream to flow between the substrate and the IR burner.

The burners of certain example embodiments may be used, for example, to combustion deposition deposit metal oxide coatings onto glass substrates.
