Or 290 grams per day.

| *Power extraction - If 0.6 gal used for 7 hours at 1/4 power with [[Honda EU1000]] - the gen set can do 7 hours at 200W. Or 1.4 kWhr. It advertises 3.2 hours at full power - or nearly 3 kW. Note that 3.2 hours at rated load of 900W - nearly 3 kWhr - on 0.6 gal gas. So it's more efficient to run at full power, which wastes less energy due to 'reciprocating pump loss'.
| |
| *'''Bottom line - 290 grams per day of hydrogen - less than 1/3 kg equivalent - means about one half the 0.6 kg (0.6 gal) equivalent tank of the Honda EU1000. Thus, we get a power of about 1.5 kWhr from the daily generation of hydrogen. Not bad. That is marginal full power storage from an eco-home with smart energy. If designed for smart energy use, then this solar hydrogen route could be completely viable. Using $3500 in hydrogen generation. For storage in a [[Propane Tank]] - bottom line is
