• Homepower article right now - up for publication
• Hydrogen Wind, Lawrence Spicer - 8 yrs ago - bought more cells -
• Couple cells still from 1994.
• 12 cells - 2v cell - 30-40A at 2V - put it in series to do a 24 v system

• Hydrogen Production article - downside - contamination on both sides - fittings etc -

• Catalytic recombiner
• bubbler

• For safety reasons, 2% of contaminant is required.
• Purifier gets you there.
• If there is a failure in electrolyzer, you can be storing
• Only hydrogen goes through palladium barrier.
• less important to Walt to produce oxygen bc of plasma cutter.
• High purity generators - are now making it safe.
• Barbecue on hydrogen.
• Common duct electrolyzer
• Flashback arrestor - section of pipe filled with sand.
• Cubic foot of hydrogen is 270 btu.
• propane - 2500 btu per cubic foot.
• Hydrocue - 4 liters per minute - 20-25 minutes to do a cooking session. 80 l.
• Pressure-based elecrolyzer. Propane tanks normally rated to 250 psi.
• Spicer electrolyzer - good at 60 PSI.
• No because of the cleanup. $2500 electrolyzer - $3500 for cleaning up hydrogen
• Trickle -
