A Hydrocarbon Hellspawn said this about CH[sub]4[/sub] [quote]It
is one of the more useful molecules out there in the long run,
[/quote]
Sure, from YOUR rather narrow definition of "useful" (It's a
hydrocarbon!).
But in the BIOSPHERE that we all depend on, THE most useful
molecule in the hydrocarbon pantheon is this one:
[center]Ethylene: The Ripening Hormone[/center]
Ethylene causes fruit to ripen and plants to die on schedule so
they can be recycled into the biosphere. In short it is key to
the life cycle of all earthlings. Now THAT is REALLY useful! So
you see, I DO recognize that there is ONE hydrocarbon that we
really need AS LONG AS WE DON'T BURN IT! [img

Back when I was trying to get through pre-med in the daytime,
while I worked as a computer analyst in the FAA at night (I was
promoted from air traffic control to Automation), I took Botany,
one of many biology courses the curriculum required.
Botany was a lot of fun. I learned how they keep grapes from
having seeds in them (Gibberrelins) and all sorts of interesting
facts about plant biochemistry. But the story of the orange
grove fruit warehouses in Florida in the early 20th century was
one I liked especially because it is a great example of the
scientific method in action. Read on. 8)
The vast orange groves in Florida around 1910 had giant
warehouses where picked fruit would be stored while they reached
the proper stage of ripeness before shipping them to markets.
The oranges are picked nearly full size and still green. They
are tough at that stage and not easily bruised by the picking
process.

The crop is stored in heated warehouses to finish the ripening
process. The oranges, as they ripen, obtain their pretty orange
color. The fruit expands somewhat and becomes more fragile but,
since they already have them packed in bags or crates ready for
shipping, they get to markets pretty well unscathed.

Well, around 1910, the orange growers were sold on
electrification of their orange ripening warehouses. They had
hitherto used kerosene heaters which sometimes caused a
warehouse to burn down and they liked the idea of controlling
the temperature within a few degrees to fine tune the ripening
process. Boy, were they in for an unpleasant surprise! :P
They spent small fortunes in electrifying the warehouses with
lights and elecric space heaters. The picking season came and
they happily picked the crop and stored it in the new and
improved hot shot electric heater warehouses. They waited for
the oranges to ripen, fill out and turn orange in color. And
waited. And waited. Those silly, stubborn oranges refused to
ripen! They stayed hard and green. [img
width=50]
HTML http://renewablerevolution.createaforum.com/gallery/renewablerevolution/3-250817122018.gif[/img]<br
/>
A bright bulb among the growers, all of whom had ALWAYS believed
(wrongly) that HEAT is what makes fruit ripen, stated that there
must have been something besides heat in those old kerosene
heaters that made the fruit ripen.
They got a team of scientists to do some experiments with green
oranges with and without kerosene heaters at various
temperatures and the oranges exposed to the kerosene heaters DID
ripen as they always had before irrespective of temperature.
Next they identified all the products of combustion of the long
chained hydrocarbon called kerosene.
We all know when you burn (oxidize) a hydrocarbon, you get
CO[sub]2[/sub] + H[sub]2[/sub]O. But that is ONLY if you have
COMPLETE combustion.
A kerosene heater, as many family tragedies can attest to, puts
out lots of INCOMPLETE combustion products like CO (carbon
monoxide) that will kill you quickly and quietly.
But there is another product of incomplete combustion that
burning kerosene puts out. It's called Ethylene. [img

HTML http://renewablerevolution.createaforum.com/gallery/renewablerevolution/1/3-120818185038-16442135.gif[/img]<br
/>
This tiny molecule is a miracle of plant biochemistry. The
scientists determined that ethylene was making the oranges
ripen!
HTML http://renewablerevolution.createaforum.com/gallery/renewablerevolution/1/3-120818185039-1655102.gif<br
/>So the growers had to put the kerosene heaters back in.
Well, they got electric lights out of the deal and plant science
took a giant step forward so everything worked out for the best.
HTML http://renewablerevolution.createaforum.com/gallery/renewablerevolution/1/3-250718210628.gif<br
/>
The obvious follow up question is, where does the ethylene, now
defined as a plant ripening hormone, come from when the oranges
ripen on the tree? ??? From the orange, as long as it is
connected to the tree when it turns color. AFTER the fruit is
sufficently ripe (i.e. the orange gets its orange color), the
tree is not required for ethylene production.
Henceforth, whether on the tree or off it, the orange itself
keeps putting out ethylene until it rots in preparation for the
orange seeds to grow. Pretty neat, huh?
HTML http://renewablerevolution.createaforum.com/gallery/renewablerevolution/1/3-120818185040-1659929.gif
This was a revolutionary development in botany in general and
fruit growing in particular. The study of plant hormones grew
explosively from that point and many mysteries were (and still
are being) solved about how these miraculous photosynthetic life
forms function.
What is so amazing to me is that such a simple molecule can do
so much. Have you ever put bananas on top of a bowl of fruit
containing apples in the bottom? Sure, everyone has.
Have you noticed how fast those bananas get overripe when they
are on top of apples? YEP, ripe apples are one of the highest
ethylene producers out there! :o Those bananas produce much
less, but when the added apple ethylene whacks them, here come
the brown spots! :P
[center][img

HTML http://www.wpromote.com/blog/wp-content/uploads/2012/06/fruit-bowl.jpg[/img][/center]
[move]Unless you are going to eat the above bananas TODAY, this
is a No No! The bananas will ripen too fast! Set them a few feet
away and they will keep longer. ;)[/move]
So now you know that, if you have a well ventilated area and
happen to have brought some green bananas from the store that
you are worried about "going bad" before ripening or just
refusing to turn yellow, as sometimes happens, a small hurricane
kerosene lamp placed in the vicinity of the bananas will ripen
them. You can impress your spouse with your botany smarts. ;D

Ethylene (IUPAC name: ethene) is a hydrocarbon with the formula
C2H4 or H2C=CH2. It is a colorless flammable gas with a faint
"sweet and musky" odor when pure.[3] It is the simplest alkene
(a hydrocarbon with carbon-carbon double bonds), and the
simplest unsaturated hydrocarbon after acetylene (C2H2).
Ethylene is widely used in chemical industry, and its worldwide
production (over 109 million tonnes in 2006) exceeds that of any
other organic compound.[4][5] Ethylene is also an important
natural plant hormone, used in agriculture to force the ripening
of fruits.[6]

The company completed three solar installations in August that
will generate nearly 13 megawatts of power and are part of a
larger 32 megawatt portfolio of solar projects called Butter
Solar Portfolio owned by Canadian company BluEarth Renewables.
Upper Midwest Municipal Energy Group has agreed to buy the power
from the projects, which will be used by ten communities in
Wisconsin, Minnesota and Iowa, potentially reducing their power
costs. Organic Valley’s CEO said the company is now aiming to
assist their 2,000 farmers with other sustainable initiatives.

You Thought It Was Impossible to Grow Oranges in the Snow?

[center]Documentary — Nebraska Retiree Uses Earth’s Heat to Grow
Oranges in Snow[/center]
Analysis by Dr. Joseph Mercola Fact Checked
September 14, 2019
[center]
HTML https://youtu.be/ZD_3_gsgsnk[/center]
STORY AT-A-GLANCE
✔ Tropical fruits can be grown in subzero climates with
geothermal energy
✔ The only heat source for geothermal greenhouses is the
Earth’s heat, which is 52 degrees at 8 feet deep
✔ Energy costs to run a geothermal greenhouse are less
than a dollar a day
✔ Harmful herbicides and pesticides can be avoided with
geothermal greenhouses
✔ Geothermal greenhouse produce is marketable at local
farmer's markets
✔ The crops can be more profitable because there are few
transportation costs involved
Finch's geothermal energy-based farming has been fruitful, pun
intended ;D. The greenhouse includes 20 citrus trees with 13
varieties of fruits, along with cacti, orchids, nine varieties
of grapes, figs, avocados, ivy, tomatoes, garden plants and
flowers.6 One 24-year-old tree will grow to be 100 years old or
more, says Finch.7
Each tree is capable of producing as much as 125 pounds of fruit
every year which Finch sells at local farmers markets.8 The
year-round growing and low transportation costs help the
marketability of the products says Finch –– and "locally grown"
can be just as much of a sales point as "organic." Finch sells
Valencia oranges, the fruit from which most juice comes. The
temperatures are so salutatory, you could probably grow bananas
too, he muses.9
Yet the energy costs associated with running the geothermal
greenhouse are surprisingly low –– less than a dollar a day. A
geothermal greenhouse Finch designed for a local high school in
Alliance has used an average of 96 cents a day in energy costs
for the last several years.10

I would love to be able to grow bananas and oranges and avocados
and even mangos here in Vermont, but I probably will never have
the opportunity. I know Amory Lovins successfully grew Bananas
in the mountains of Colorado (his [img

/>still does 👍).
I grew Bananas in Puerto Rico and had an Avocado and Mango tree.
Bananas are easy to grow in the tropics and are generally
impervious to bugs. Birds can get to them, but only when they
are so ripe they are falling off the plant. You need to harvest
them before that point is reached. The plants don't get much
higher than 12 feet or so.
Mango and Avocado trees get way too big (over 30 feet) for a
trench, so a dwarf hybrid would have to be the only type you
could grow in a covered trench. Avocado and Mango trees must
grow for at least 7 years or so before you can get fruit.
Avocado trees are peculiar because they are both male and female
(at different times of the day to prevent cross-pollination on
the same tree). Usually you need another Avocado tree nearby for
proper flower fertlization. Mango trees don't have that problem,
but hybrids revert to more stringy fruit (harder to eat)
versions rather easily. You need to have similar hybrid trees
near each other to keep the fruit true to the hybrid brand.
Mangos are not like apples, which have a uniform pulp texture
across most varieties. Mango texture can vary widely from easy
to eat to a fruit dense with stringy "dental tape floss" like
fibers all the way to the seed. The versions we get in Vermont
are low fiber, peach easy to eat, but pretty bland in taste. I
suspect they are picked when they not fully ripe so they aren't
damaged in shipping. There is nothing like eating a mango, or
any other fruit, for that matter, when it has fully ripened on
the tree. 😋

Carbon Dioxide levels in our atmosphere continue to climb, as
does our global atmospheric temperature. Despite greater
awareness of the issues, and huge strides forward by the
renewable energy industry, we are not having any effect on the
overall problem. But some people think we're looking in the
wrong place for the solution and that all we need to do is take
some lessons from the way nature has always used it's resources
to regulate heat across our blue planet.

Regenerative Agriculture has been around for a very long time.
The trouble is it's just not the way most modern farming
techniques are taught or practiced. Walter Jehne is an
Australian microbiologist who argues that with a few very simple
changes to the way we manage our land, all of which are just
taking a lead from nature, the answer to reducing our global
atmospheric temperature could be as easy as A-B-C...
