Does Propane go bad?

They just got approval for a 3900 acre solar farm at Christmas Valley. Five new wind projects launched in 2021. Wind already supplies 82 gigawatts, and is growing fast.

5 US wind energy projects starting in 2021

Studies predict more than 600,000 jobs will be created in wind energy by 2050 in the USA. Read about key projects, sustainable future, and opportunities.

States spending the most on wind power projects over the next 10 years:​

• Texas is the state that will invest the most in wind energy, with spending estimated to rise to $16bn on 26 projects in total.
• With spending estimated to $15bn, Massachusetts will create job opportunities in 6 new projects.
• With a cumulative investment through 2019 of $4.2bn, New York will build 18 new projects with spending estimated to $11bn.
• Wyoming will invest in 10 new projects with a total value of $9bn.
• New Mexico, where the installed wind capacity is 1,952MW, spending estimated to $6bn in 8 projects.

Yep, the new environmental disaters. And what happens when the sun isnt up or the wind dies off? 3900 acres being clearcut and thats a good thing? How many govt subsidy dollars are propping up these pet projects?

“While we humans get most of our carbon from food, trees breathe it in (just like we breathe in oxygen). But when a tree breathes, it inhales carbon dioxide and exhales oxygen — the exact opposite of humans. And as a tree matures, it can consume 22lbs of carbon dioxide per year (among other greenhouse gases like ozone), and release enough oxygen for you to breathe for 2 years!” https://onetreeplanted.org/blogs/stories/planting-trees-reduce-carbon-footprint

Geothermal would pay for itself if you're using either straight electrical heating or heating with NG or propane/butane. Saves at least 2/3.

Geothermal heating for a residence consumes more electricity and typically has a 20+ year ROI.

I'm sorry. You're wrong. There's a 3 to 4 COP for geothermal. It will save 2/3 to 3/4 of the energy compares to straight electric or NG/propane. Bet the ROI is much better than 20 years.

You saw a tree? Where? Even the juniper dies of thirst in that area. Nobody would complain about clear cutting 3900 acres of Russian thistle, AKA "tumbleweed." Oregon has extensive land use laws, and the project got approval because that land grows precisely nothing. The big ecological concern was if all the lizards and snakes would have to relocate. It's in the middle of a huge desert.

They recently invented things called "wires" to move electricity around. The wind is always blowing somewhere.

I spent a year in Glennallen, AK. Good Morning - Doofy. Everything was run on propane. Electricity was more expensive than GOLD.

Never had any propane "go bad". BUT - it would get so cold - the propane would loose its pressure and not flow. Propane had to be in a heated shed or some form of heated enclosure.

Yep, our regulators would freeze up between -40 and -65. We would have to pour hot water over the regulator while holding your finger over the screened vent. We also would throw an old piece of fiberglass insulation over the tank with a light bulb under it.

Haven't had any problems since the advent of Global Warming...just doesn't get that miserably cold any more.

Huh.

I agree, global warming is a good thing!

Ethyl Mercaptan (the odorizer in propane) is heavier than propane and can possibly seperate out if not used for a long time. Or can be absorbed by rust in a tank. So you may not have the safety of being able to smell a leak under various conditions.

I'm curious, do you have any data for ethyl mercaptan actually separating from LPG/propane?

I can't find any. (Bad Google-fu?)

Because the densities are so close, and the amount of mercaptan so low (1lb/10,000gal) that separation seems improbable to me. (Newton's 3rd law and all that.)

Part of the reason that ethyl mercaptan is used is because it is so resistant to degradation.

All the best,
