  • Walt pyle - founder, http://hionsolar.com/ - download Solar Hydrogen Chronicles from his site.
  • PEM electrolyzer - elimination of gas cylinders. Got one on ebay - $120
  • 60 psi storage
  • 2 125 gal propane tanks
  • 9 5 gallon tanks
  • 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
  • Spicer - 2 generation - envelope to separate the gases instead of fiberglass separator.
  • 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.
  • Liter per minute -
  • modify an engine to run on hydrogen -
  • Electrical contractor, electrical, mechanical engineer.
  • Water splitting on thermal decomposition -
  • Solar systems and alt energy
  • Little wind and hydro, mostly solar electric.
  • High end CNC machines.
  • Cracking water and CO2. To make solar fuels.
  • 70% of the hydrogen in the world goes to make electrolyzer.
  • Interested in a decentralized system with onsite farmer ammonia
  • 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 -
  • 1994 - $6k parts.
  • I can deal with it, but I'm an engineer.
  • Potassium hydroxide - is used.
  • Perfluori ethylene, sulfonic acid chains. H ion to H molecule. Has catalyst on each side, Pt group catalyst. Sandwich.
  • Ultrapure hydrogen unit. Lab tech product.
  • Simple plans for oxyhydrogen cutting. Off the grid - Sunnyboy inverter - day power when grid is down. SV TLUS. Interesting solution - off-grid for day power.
