My solar still has been producing about five gallons distilled rainwater every four days recently. I've only bought one bottle of drinking water this year. (I was at a concert in Austin. I saw Jon Anderson (of YES fame) at the Paramount Theater. His voice is still great!)
That was the first plastic bottle of water I've purchased in years...

There’s a strange irony related to this subject [oil and gas extraction] that the better you do the job at exploiting this oil and gas, the sooner it is gone.

Cool, solar power from solar panels is way to go! This is one cool way to maximize the use of the renewable sources of energy and green way to consume energy. Solar Power In Queensland

$this->bbcode_second_pass_quote('PeakOiler', 'H')ow much would it cost to buy 5 liters of bottled water every summer sunny day from the grocery store where you live? I don't know what the price of bottled water is currently since I never buy bottled water from the grocery store.
I'll leave it as an exercise for each reader to calculate the "payback time" of a solar still from the water produced vs. store-bought bottled water.
Got good solar insolation?

Given the price of store bottled water, payback time would probably be short. Regardless, sometimes payback misses the point. A solar panel that charges the battery that runs the mini-cooler that cools your insulin will not start paying back until there's no electricity for a few weeks and gas shipments haven't quite restarted yet. At that point, however, it could literally be worth your life.
For that matter, how long would a higher seawall at Fukashima have taken for "payback?"
This is another "Fail" in capitalist economics. Survival and more can't be all about the money.

I'm glad to report that possibly only one plastic bottle of water that I bought is floating out in one of the Pacific gyres. If that one plastic bottle bottle of water that I drank in the last 5+ years is in the landfill, then NO plastic bottles are in the gyres on my account.
Meanwhile I have over 20 gallons of distilled rainwater on hand for drinking and cooking purposes.
The still is doing quite well with all these blue skies. BTW, the solar water heater has recently been putting out 85+ C water!
I'd rather have some cloudy rainy skies for a little while, however, than the constant baking sun...
