Well, I completed my three quizzes and the test. My quiz scores were all over, 85%, 89%, and 78.5%. I woke up yesterday with a sore throat and upset stomach, developed a headache, and did not make great progress through five chapters and five video lectures, but I earned a 96.3% on the test. Unlike ASU, MUMU does not use weighted grades, so as long as I earn an 87% on the final, I will have an A in the class.
This does not give any specific numbers, but there is an effort in India to replant forests, which has affected eight million people:
China has planted at least 66 billion trees on the edge of the Gobi desert since 1978:
People in eleven countries in Africa are planting trees to push back the Sahara:
The Prime Minister in Pakistan has promised a ten-billion tree tsunami: https://www.independent.co.uk/news/w...-a8584241.html
I could not find any good videos. I needed to scroll through dozens of obscure results before I found that one.
Australia is planting trees: https://www.bloomberg.com/news/artic...limate-targets

When I was a property owner, I rented rooms to tree planters; Like the Hoedads, but some other group.
https://fernnews-wpengine.netdna-ssl...y-1024x700.jpg
wikipedia.org:Hoedads_Reforestation_Cooperative
They were good housemates because they were very quiet when they came home (with their pants and gloves ripped to shreds). They were hard working people.
Today they just shoot tree bomblets from drones. https://www.fastcompany.com/3060331/...s-from-the-air
Quote:
The drones have a flight time of about 30 minutes and can cover an acre in 1.5 hours, Kozak says. They fire out seed pods–containing a mix of “fertilizers, hydro-gels and pest deterrents”–at 350 feet per second (for comparison, paintballs travel at about 250 feet per second). The capsules nestle three or four inches into the ground. In addition, the drones can also spray herbicide to kill invasive species that harm tree growth, and they can measure tree diameters when the saplings are established.

Ah, seed balls. I was trolled when I shared those here: https://ecomodder.com/forum/showthre...eds-36530.html
I wonder if they have those drones in Arizona. As I have mentioned, the only recovery from a huge forest fire seventeen years ago is grass, which apparently they planted from a helicopter.

Ahead of your time ...at least on Ecomodder.
I like the idea of quadcopter drones for fighting forest fires, with sonic blasters and foam guns. For controlled burns of course.

Baby steps. Plant grasses and wildflowers first, then in a year or two, trees.
Drones FTL. Any given acre can be planted the same way much faster by an actual person or (the horror) simply scattering the seed balls from a real plane. Yes, it looks like it costs more that way, but unless you set up your drone ops right next to the acre you're seeding, how much of your 30 minute flight time is spent in transit, and how many 30 minute flights do you need to spend 1.5 hours actually seeding that acre? And if you are set up right next to that acre, a bag of seed balls and a planting stick can seed that acre in a lot less than an hour and a half. If you use a plane, you get more speed and carry more seed balls. They may not be planted 3" below the surface, but clay with fertilizers, hydro gels and pest deterrents ought to do pretty well just lying in a divot.

https://www.urbandictionary.com/define.php?term=hoedad
Quote:
A Hoedad is a tool used to plant trees. The Hoedads Cooperative was a unique social and political workforce whose members consciously or unconsciously partook in a restoration and healing of the northwest timber industry that too often was (and still is) motivated by greed instead of sustainable and sound practices.

Take a look at the picture in Permalink #12. That terrain is typical.

Have you ever done that? Take a look at the picture in Permalink #12. That terrain is typical. I lived with tree planters. They have a rythm, swing the hoedad, open a hole a foot deep while you grab a 12-18" tree, drop it in the hole and heal it. Rinse and repeat over a hillside covered with slash. It's not a job for the unfit.
Spray and pray from an airplane wouldn't be as effective as a first person shooter from a drone.

I am caught between the discussions of battery range extenders that mathematically do not make sense, just use a generator, or the ridiculous and disproportionate amount of emissions from small engines.
Here is a drone that can sustain over two hours of flight with gasoline: https://www.quaternium.com/uav/hybrix-20/
You can't use gasoline to plant trees!
Would the small aircraft somehow pollute less?

Pure steam has almost as much lift as helium, but requires energy input to maintain lift. Electrically excite the steam and you have reaction jets for station keeping.

All dimensions are metric except it has 30" propellers, so it's about 5ft long. All the proposed uses are observation, the payload is 2.5kg [5.5lb].

What's the advantage of a quadcopter? A helicopter is more efficient, and have been around longer.
I keep asking that question, and nobody seems to know why quads caught on while helicopters did not. There's no reason a heli couldn't incorporate the same control schemes used to stabilize a quad.

For drone size copters the quadcopter is mechanically simpler. You don't need the complex mechanism to tilt the rotor fore / aft and side to side to control pitch and roll. Instead you just vary the speed of each rotor. That should make quadcopters cheaper to manufacture.
