Won't work one study I read a long time ago when I was doing my pleb 2 year degree for applied science in wind power generation there was one study that said wind turbine blade lost at least a few percent of their integrity between day 0 manufacturing and getting them to the wind farm.

How do we make a composite that gets stronger until failure, like aluminum does?

Roman concete. It might be a little hard to make a windmill of it.

Else nanoscale 3D printed metamaterials (GRX-810) that's a thousand times stronger to start.

I've been holding my breath for carbon nanotubes to solve every problem.

We are so far beyond Buckminsterfullerene.

2D Boron Nitride Heterostructures: Recent Advances and Future ...
10 Aug 20211 Introduction. Since the first isolation of graphene from graphite, 2D materials have immediately opened new exciting perspectives in materials science and engineering. [] Hexagonal boron nitride (h-BN), in particular, which has a layered structure similar to graphene, has attracted much attention because of its unique combination of properties.

Structured Water: Legit Science or a Hoax? | HealthNews
21 Mar 2023Structured water is a hotly debated theory of how water molecules may interact and form a stable hexagonal shape. If true, this molecular structure means scientists discovered a new fourth phase of water, in addition to vapor, liquid, and gas. The practical applications of structured water are impressive. Key takeaways:

If I don't have (or have the possibility of having) a thing that's useful to me, then it resides in the theoretical, which is a slight promotion from fantasy.

Solipsism
Solipsism is the philosophical idea that only one's mind is sure to exist. As an epistemological position, solipsism holds that knowledge of anything outside one's own mind is unsure; the external world and other minds cannot be known and might not exist outside the mind.

For me it's more like the revealed truth of External Reality allows increasing latitude. Once it filtered down to Goodwill and BRING, then I get to have some.

Today I was looking at corrugated sheet materials at BRING. Hold two sheets at different curves together and rivet the edges; then a halved 6" PVC pipe at the [trailing?/lewading?] edge and I'd have the very latest VAWT.

Also, about the fiberglass. According to LEAKED Titan Sub Transcript Shows Crew In Battle For Lives, the Titan used microphones to listen for cracking noises. What could possible go more wrong?

If they are running Microsoft as an operating system?

I can see a couple percent degrade during transport because they don't have closed containers and some are made in sunny florida then take a while to get where they are installed. I think it took 50 gallons to paint coat the blades which was something like an extra 100 lbs non structural

All concrete continues to gain mass and get harder over time.
By the hydration reaction in the Portland cement and by forming carbonates with CO2 and water with other minerals in the concrete.

I tried to drill into a concrete porch step that was cast in the 1940s. It was like that.

Off-topic, but it never stopped me before....

The primary objective of an air curtain machine is to reduce the particulate matter (PM), or smoke, which results from burning clean wood waste. Using a technology called "air curtain," the smoke particles are trapped and reburned, reducing them to an acceptable limit per U.S. EPA guidelines.

Clean wood waste is loaded into the FireBox, and an accelerant such as diesel fuel is used to ignite the wood waste, just as you would start a campfire or open burn pile. The air curtain is not engaged until the fire has grown in strength, or the air curtain may blow the fire out. Once the fire has reached suitable strength, usually in 15 to 20 minutes, the air curtain is engaged. The air curtain then runs at a steady state throughout the burn operation, and the waste wood is loaded at a rate consistent with the rate of burn. Our smallest machine will burn at a rate of 1 to 2 tons per hour; our largest machine can burn in excess of 10 tons per hour.

It looks like a vortex generator, exhausting clean hot air. I wonder if it powers itself or charges batteries.
