I wanted to see how much propane we have used....3 weekend trips and one 8 day trip.  Though I can't verify how full my propane tank was new, I pulled it off and stopped at Costco.  1.81 gallons is all it took to top the tank off.  $4 bucks is all for that usage.  Not bad.

LOL! None of of strayed from the straight and narrow in 1965. It wasn't until 1968 that we started to get kinky. Star

I moved to SF for college in '67 and I promise, it was pretty strange then.  In 1965 it was pretty kinky even in places like Bakersfield, .... one of the many reasons I left.  Not even the electrons and protons would follow the rules.

Solar is still electrical, and the rules for electricity have not changed. Solar panels have gotten invented, and improved now for a few decades, but the rules were created by Georg Ohm in 1827. Those have not changed.

Hey, c'mon, you guys are off by 15 years. 38 years ago was 1980.  I'm not so old that I was doing solar in 1965! I was 11 and PV was only on a few comm satellites then....

By 1980 we were selling it commercially. Our big markets:

Norcal pot growers for pumping water and navaids for the Coast Guard. 

The price? $15 per watt...in 1980 dollars ($46/watt in 2018 dollars). Yep, only the government and pot growers had enough cash for solar modules back then. Talk about economies of scale, that's a 100 fold price decrease. Unfortunately, we have to thank the Chinese for that, we gave up our leadership in solar manufacturing in the late 90's.

I'm just kidding folks, I never really did anything bad in 1965.

Yep, you are correct Our Pod. There sure are. The longest lived one is He6 with a half life of 801 milliseconds. And because of this they don't exist in nature.  Only He3 and He4 which are both stable. So the radioactive He isotopes are irrelevant.

There are isotopes of helium, and these have half-lifes. This fact does not support any claims of a young earth.
Life is good.

Are you sure it was helium? Helium is stable, doesn't have a half life. Helium is the least chemically reactive element known, so it doesn't participate in the biochemical reactions required by living things, or any chemical reactions for that matter. 

Helium is useful for life for breathing mixtures for divers as a substitute for nitrogen to avoid nitrogen narcosis, aka "rapture of the deep".  It's also good for filling dirigibles rather than using hydrogen, just ask the Hindenburg survivors if any are still around.   

And speaking of potentially exploding gas containers, that brings us around to propane tanks so we are back on topic Big smile
