Hey, I can stay on-topic here.

An helical vertical axis tri-plane wing.


https://static.turbosquid.com/Previe...8ddaLarger.jpg

The airfoils would be timber bamboo, split in thirds, lashed together and twisted when they're green, then the airfoil shaped and carbonized when they are dried. The culms would attach to the shaft via three struts.

20ft of hex bar to act as a torsion bar that stores energy to spin up from stopped.

That is a problem.
Quote:
The money goes to everything from fish ladders to get around the dams to habitat restoration to hatcheries. Today an estimated 80% of the fish on the system stem from hatcheries.
Salmon cannons and hatcheries that are free-floating geodesic domes in the ocean. Hatchlings are given a free ride to the ocean, so they retain their primal urge.
Quote:
And yet the salmon continue to decline, from historical numbers of 18 million in the 1800s to barely 2 million today.

For tribes, this represents another broken promise with the U.S. government. McCoy Oatman, a tribal councilman for the Nez Perce, says his people depended on the fish for nutrition and survival before being forced onto a reservation that today only includes a stretch of the Clearwater River.

"We want to be healthy individuals like our ancestors," Oatman says. "When our bodies are not able to consume our natural foods that has an impact on us as a people."
Reason enough to do it right there. Plus the capitalism in the article.

As a test I told them this joke:
Bernie Sanders: 'When I was young the only thing we had to listen to was AM radio.'

AOC: 'What did you listen to at night?'
They didn't know why it was funny.
