BTW, I didn’t include deposits on the bottles or meals for the driver. I assumed the villagers would take car of the driver.
You keep digging a deeper hole for yourself.

If the cost is 'free' to produce the hydrogen, and the labor (and other costs) are free, then, a driver coming from elsewhere can also be free; no cost for bottles or meals, etc. That is, using your method of 'free' everything. Get it???

“a driver coming from elsewhere can also be free;”

LOL! The driver doesn’t work for free!
