Abstract: This new ceiling fan is designed to improve functionality of the airflow and to decrease the obtrusive appearance of the traditional axial ceiling fan by incorporating the lower profile airflow technology of a centrifugal fan. The main advantages are that it is much smaller with a lower profile that is mounted flat against the ceiling and can have more focused directional airflow thus enabling a user to feel more air circulation in the specific area of the room. The fan can also be set to oscillate around the room for more diffuse air circulation. Low profile lighting kits can be designed into the lower cover. This new design should be easily mountable on existing ceiling fan electrical boxes. Ideally it could be controlled with the same remote control technology available today for floor standing oscillating fans.

The purified hydrogen gas contains little to no trace of chloramines and chlorine impurities, thereby making the hydrogen gas suitable for liquid hydrogen production.
