I was pretty much up on most of the info except for the wine brine soaking, the water in the oven to make a crust lighter and the drying out boiled potatoes to get fluffier mashed potatoes. 8)

Our Geodesic Dome Connector - How it Works! 💫 https://youtu.be/v_NnY_yYwuc 26,672 views Zip Tie Domes
Published on Dec 25, 2017
https://www.ZipTieDomes.com - This video is about the design and fabrication of the Zip Tie Dome Geodesic Dome Connector / Geodesic Dome Hub. This Geodesic Dome Connector is very easy to use and allows the construction of a Geodesic Dome without the use of tools and in a minimal amount of time. The video describes the patented locking collar that surrounds the Geodesic Dome Hub, and how this outer collar controls the axial angles of the struts to create a much stronger geodesic dome than other types of Geodesic Dome Connectors. The video also describes how this is the only geodesic dome connector that can handle struts made out of non-standard size struts, such as metal rebar for concrete domes, or geodesic dome struts made from wooden dowels. This geodesic domes connector also works for building domes made from bamboo and other non-standard size struts. 🌟

Uprooting a tree using a 45 to 1 pulley system --- Quote ---Scott Moszkowicz 1,242,979 views

This is part 2 of my project to remove a back leaning tree. This tree needed to be removed in this manner. I am pouring a cement slab right where this tree was. Using a chain saw or even digging it out would not have completely removed the roots. Not removing the roots (over time) would decay and cause the ground to sink. --- End quote ---

It would have gone a lot faster if he just used some dynamite. ;D

Glad you liked it, Eddie.
RE, always wanting to do things FASTER is what got us into the mess we are in totday. And dynamite harms the soil. Using pulleys is the most environmentally sustainable way to engage in brute force actions like uprooting a tree.

It was a JOKE AG. ::)
You will note though he is still using an FF powered winch to yank the ropes. You can hear it in the background.

Okay. ;D Yeah, I noticed that about the winch. ;) But an electrical winch would have done the job just as well.

You couldn't set up an electric winch there, at least not straight solar. Too many trees around, not enough sunlight hitting the ground to power the winch. Similarly, not enough wind to power wind turbines when there are so many trees blocking the wind.
If you have a big enough portable battery bank you might do it, but that would be outrageously expensive, along the lines of the systems that DB sells and sets up. This is out of the range of most people, you and me included there.
Dynamite comes cheap, and it really doesn't damage soil all that much. It actually blows a lot of nitrogen into the soil.

I didn't say a thing about a solar powered winch. All tow trucks use an electric winch. Yeah, the source of energy ends up coming from fossil fuels, but the point is that electric motors, because of their instant and high torque performance, are the best type of motor for a winch. In fact, nearly all pulley applications (e.g. elevators) in modern society are applied with electric motors. Yeah some of the big cranes are fossil fuel powered but that is changing. Electric motors are better for use with pulleys. I had a friend who was an electrician on an oil platform in the ocean. They use LOTS of electric motors on those platforms because internal combustion engines have a bad habit of destroying clutches when used to lift heavy objects. Electric motors do not burn clutches simply because they do not need clutches.
The nitrogen compound that dynamite puts into the soil is not the same as the same as that contained in chemical fertilizers. If you want to believe the soil microbiota "benefits" from an explosion, then I will have to disagree with you. Killing thousands to millions of microbes in a blast won't improve their appetite for fixing nitrogen so plant life can benefit from access to nitrogen.
All that said, since this guy just wanted to pour a concret slab where the tree used to be, he certainly could have used dynamite. The concrete slab is the end for that area of usable soil.
