How to prevent wild fires.

A dome won't sway. The summit is constrained by the [concentricity?].



Where did that number come from? The (double-hulled California) swimming pool?

Why did you work on broken software instead of architect structures?

I've been thinking my living should be related to the things I can't help but spend time on, seeing how I've used up half my days now.

If I put in even an hour a day on either one I'd see some progress. Things move slowly. I can't just get up out of a chair; I have to first think about how to get up without hurting myself, then lean forward until I'm looking at the floor, lift with my legs and then stand upright. Yikes, I'm starting sound like Xist.

I'm making incremental progress in Blender. Things react in unexpected ways and there are known unknown shortcuts and keyboard equivalents to learn. But it's free.

For physical structures, the current new thing (truncated 3v octahedron) could be built with ~$352 in materials -- 22ea 1.5"x12' aluminum pipe). I just bought a box of soda straws to make a model for $1.25.

Here's what I've got so far. It's too nice a day to spend indoors.



It has soffited overhangs, tilt-up decks and a globe of water at the top. Detailing of fenestration and function of the water tank/solar collector/skylight remain.

Only took 5-6 hours so far. Mostly on that skylight, Box Select on vertexes wouldn't work so it got tedious, and it's still not done. Still it's set up for what it needs to do.

Perhaps the various house sizes could be represented by a letter system, with the lowest volume ones considered A-size, and each larger increment given an incremented letter designation. Sometimes double the letter instead of incrementing to the next letter, just to mess with people.

[freebeard]

Else you just put two of them side-by-side.

I'll work on the water globe tomorrow today.

That's not a sprinkler -- this is a sprinkler:

RainStream™ Using wind to fight wildfires in the wildland urban interface

3,083 views Premiered Oct 7, 2024
Wildfire Innovations Inc. introduces RainStream™ , a 100 ft. tall telescoping mobile tower on a trailer integrated engine/pump system. RainStream™ covers large areas, using the wind to carry a protective mist, rather than burning embers. RainStream™ turns any hydrant, water body or storage into rainfall in the wildland urban interface. It fills the large gap between ground sprinklers and aircraft supported wildfire suppression. RainStream™ can be used to proactively mist areas under extreme wildfire risk.

according to this, it covers 20 acres at 1000 GPM.

I notice they are pumping from a lake or pond. Wont work here in Reno, might work n Washoe valley where they had the fires if they can use less than 3 ft of draft. this time of year the truckee river it at minimum flow, less than the 1000 gpm that thing wants. They can increase the flow out of the impoundment lakes, but it takes all day to get here

Might be wrong about the implementation, but it looks like you need to predict where the fire will go just to set it up. Figure large diameter pressure pipe for the feed.........

It appears to be a standard fire hose. Hydrants should work anywhere but California.

It sucks on the hose like a big pressure washer.

Here's how far I've gotten. Someone needs to light a fire under me.



The two movable sections need to be separated and set to rotate around their polar axis. The North face extends up into a central spire. This needs to hold the Rainbird, any antennae and a Tesla lightning deflector.

Can't reliably get 1000gpm from your single standard hydrant anywhere for long, or so I understand from talking to fire officials when I ran the HOA. Need a big tank somewhere and at least 6"-8" dia supply pipe. Ten minutes pumping pretty much drains those pressure buffer supply tanks and pressure /flow drops like a rock. Turn up the suction and you collapse the supply pipe. Some parts of Reno have million gallon tanks on hilltops but you need to be 20ft lower to drain them fast. Would be like a half time commercial on super bowl sunday
