Tankless Scuba Diving System on the way

IsraCast: Technology in Israel

An Israeli inventor has developed and tested a system to allow scuba diving without the large cumbersome oxygen tanks currently used. Evidently, fish get their oxygen via filtration to get air out of the water that gets into the water due to waves and currents etc. This new system uses a battery powered fiter and centrifuge to extract air from water. The lab model has been tested successfully and he is moving to a full-size prototype now.
