	*'''For sensemaking - $1-5k capital costs per kW electrolyzer. A 1 kW electrolyzer - for reference, the 500 ml/hr generator in link above requires 180W.''' If we take the electrolyzer above at $1k for 500 ml/hr - we need about 5 of those for 1kW of electrolyzer - or about $5k. But it takes about 24x as much electrolyzer to generate 10kG/day (or 10 gallons per day). Each 1000 gallon propane tank can store about 1.2kg of hydrogen, at 4 atmospheres. Capital cost there is $5k x4 or $20k for the electrolyzer. That's where open source comes in - to attain mass production via production by the masses. The complexity cost coupled with parasitic loss can be displaced by distributed production.		*'''For sensemaking - $1-5k capital costs per kW electrolyzer.
