Experimental Wind Turbine Tower Project – Using a Tall Tree (Part 2)

2 Apr , 2016   Video

A video about raise up a super tall tree into the air with a bunch of pulleys and then see how it functions as a wind turbine tower. The goal of the project was to source materials for a 50-foot tower, in this case, a skinny, tall, dead tree. Then use a living tree as the “crutch” to winch up and support the dead tree.

After testing out the new tower, the next step would be to attach a medium size wind turbine to the top of the dead tree. This would put the wind turbine high up above obstacles, hopefully make it spin faster and generate power.

Another benefit, since the tower is attached to another tree for support, no guy wires would be required and it would blend in with the background. The actual wind turbine unit would be on a slight angle so that the turbine would avoid the tree branches.

Tall trees? I have lots of tall trees to choose from. The cabin is located in a small forest that was devastated with an insect called the Mountain Pine Beetle. It killed off many trees in different stages of life. What I was looking for was a tree that measured roughly 8 inch wide at the base and as tall as a 50 feet. The type of tree is called a Lodgepole Pine (see link below). The trees do bend a bit, but are quite durable.
FYI: I’m afraid of heights. It scared the poop out of me going up the extension ladder to attach the chains to the support tree. It was only 22-feet up, but when the wind blew through the trees… it was a little nerve-racking.

The next step was to find a good place for the tower. It had to have a decent tree for support, get clean wind, close to the battery bank and could safely be raised and lowered. I also have to keep in mind for my neighbors. If I had a problem, could it fall on their cabin or outbuildings.

Wind-turbine-on-bunk-house The current location is on top of the bunk house. Aside from the vibration noise, the roof ice has managed to dislodge a support pole. It sits only 15 feet up and gets little wind. Lowering it for maintenance is a little difficult too. My power pulley works great for lifting , but it doesn’t reverse in power mode. The user has to manually pull the wire off the spool.

For this test, my good neighbour lent a hand and we used his DC powered Warn winch on his jeep. It made the process of lifting the dead tree really easy and safe.

Watch the video and see what happens.
