	*This is ~~great~~		*This is 86 kg of hydrogen per day, or about 10 microcars per day. Fleet of 70 cars all together. Somewhat marginal.
			*But it's still $250/day - or $7500 per month, or $94k/yr. This is ok. Payback time of about 4 years for the PV panels, and overall 7 years. Wow. This would change history.
