I'm looking for a similarity to T-150 C-pillar 'turning vanes' in vain. Maybe it's because of the open suicide half-door. When I think of flying butter-arses, it's the modern Ford GT40, the VW Golf GTI650-W12 or, for pickups, the Yamaha Cross Hub

Back to the pictures: 'Cowl induction' hood, the rooftop vortexes start at the windshield (!), the flattening of the flow aft of the gully between the rear fender flare and fence formed by the side trim, The snowballs on the wheels, the effect of the rear view mirrors. On and on.... Icicles on the tail-lights?

I've been reading about aircrete. It is Portland cement mixed with a 200:1 mixture of water and Dawn dishwashing soap, and a bubble size around 10 microns. One could bury a car in a mound of the stuff (a stiff mixture, with a touch of white glue) parked behind a tubojet like the ones they use to blow out oilwell fires.

A sacriifcial body to make a male mold? But the stuff floats on water, maybe hollow it out with an air tool and paint it?

I got curious, so I tried to get sciency, and the jury is still out whether it went better than when I shrank marine wrap over the front end of my Forester: https://ecomodder.com/forum/showthre...reply&p=556153 From that thread:

You can find Youtube videos of someone holding a block of aircrete and holding a blowtorch on the other side. It's like the Space Shuttle's tiles.

Concerning the compressive strength of aircrete; you'll need reinforcing. How about basalt?

You could use zarcronium bearing fiberglass or polyester fibers for reinforcement. Works real good with concrete.
I don't know if basalt can take CaHO exposure.

Maybe I need more oil on the pan. The brick came out pretty easily, but left a layer on the pan...

...cemented on.

It crumbled all over and I took it to the garbage outside to break up, but the middle did not break easily. I did not attempt to torture test it, I broke off what came easily, and that is what is left.

Actually rectangular pans, more oil, and trying to leave it higher in the middle?

At what point should I be able to turn it over?

https://www.youtube.com/watch?v=Nd7wV0J671A

It has a concrete foundation, metal studs, and the roof is plywood and 2x4s, He laid down each set of studs, cut metal mesh to fit in between, poured aircrete, screwed them together using braces that seemed to be scrap metal, built a crane to lower the cables that he built in a similar fashion, and he said he was going to pour aircrete between the layers of plywood in the roof.

Stucco on the outside, plaster on the inside. The last video is from six months ago and it was still not finished, but I thought that it looked great.

For reference, YouTube recommended this video where a guy made a 12x16 shed for $2,600: https://www.youtube.com/watch?v=LaN1hnR7pSk

The video is almost 100 minutes long. I did not get very far! It is just plywood, siding, 2x4s, and OSB. It has a wooden floor sitting on nine concrete piers. He did not install any insulation.

62% less cost for an insulated building on a concrete foundation sounds like an amazing value.

Actually, someone told me about them here about a year ago. As I recall, they said it was a slice of IPS, but I cannot find it now:

When I opened that video, YouTube recommended videos of the same channel of the guy leaving Aircrete and of some product he claimed was much better. That thread wandered into different topics. For a bit, we discussed making bricks from compressed earth, but Arizona regolith is absolutely wrong for that. We discussed greenhouses briefly, and here is a post about crushing glass to make sand for different industries: https://ecomodder.com/forum/showthre...tml#post675628 We also discussed different insulated building blocks, insulated studs.

Somehow I missed the quote that shaving cream wouldn't work, but then again, they wanted you to purchase their product instead.

Winter in the mountains of Arizona might not have been the best time to experiment on that.

I may finally have time for projects this summer, but since I am not supposed to graduate until September... I keep asking people what I will do.

So far, my best plan is to apply to schools for my clinical fellowship year, but say "Okay, sorry, my school is being weird. They require me to work for an additional 60 hours for free before I can work for money. Will you allow me to work for free for 7.5 days before I officially start work?"

Of course, the "Problem" with schools is they are off for the summer.

I always hear that speech therapy is available if families want it, but I never hear of families taking the schools up on it.

My summer is only one month long, but I really don't want to still be living off student loans.

I desperately hope that my school lets me work for the superfluous 60 hours for free and graduate, they insist that we spend at least 25 hours on-site each week, regardless of how many clinical hours we get, so some of us are spending at least half of the time idly because there isn't enough therapy to do.

A classmate complained weeks ago that she has enough hours to graduate, but is stuck reporting for work 25+ hours a week through May.

That's cool, I am stuck until at least September.
