I just saw this online.
Rather interesting as he states 2.5LPM hydrogen for 1.5 amp current.
Kind of expensive but looks well built and compact.
However it would be nice to dig into this a little, 2.5LPM at 1.5 amp is outstanding.
http://www.aquatune.com/overview.phpThat might be an error at 1.5 amps it should have read 8 amps 1.5 atmospheres.
