I want to build a 100-mpg car (and I want it to look vintage)

Is this some American saying where now I am supposed to be suddenly mute? I am just guessing - it certainly means nothing much this side of the world. (And I didn't come across it when I was twice in the US.)

I have never heard it in person either, but I believe you can take it as he doesn't want to talk to you anymore and is expecting you to leave the thread (or room if it was in person).

To be honest, I think the huge underlying issue - that I am afraid you, Freebeard are a strong part of - is that speculation has become largely the culture of the group. To be blunt, posters just guessing.

What we have here is a failure to communicate. When I say Thee Holy Template, I'm mocking it. I consistently point out when people failed to understand the significance of the hemicircular cross section.

I favor an asymmetrical octahedral geodesic as a 'template', due to it's mathematical rigor.

This is Sparta Internet!

"I bid you good day' is pretty gentle, consider r/copypasta:

What you've just said is one of the most insanely idiotic things I have ever heard. At no point in your rambling, incoherent response were you even close to anything that could be considered a rational thought. Everyone in this sub is now dumber for having listened to it. I award you no points, and may God have mercy on your soul.

OP's thread, OP's rules.

I was looking at the Blue Bird land speed racecar thinking, "How could that be made streetable?" Then I saw that toy, which looks retro-futuristic. I would draw what I have in mind using Solidworks, if I had internet access at home.

I did not realize you work under that handicap. You have a paid seat for Solidworks? If you had a computare at home, you could take Blender home on a thumb drive.

Getting this thread somewhat back on track seeing as people would rather argue.

This paper
Design and development of the Sunswift eVe solar vehicle: a record-breaking electric car from my collection of aerodynamics papers is quite good and may be of use to you

Cars are 3d and so only the centreline shape (in still air) will have true front to back flow, a template may work for a certain shape of certain width with certain curvature in certain places, but that is not necessarily representative and small deviations can, but not always, cause large effects.

The above paper shows the refinements to a design rather than turning a template into a car, same end result, different starting point.

Interesting paper - and a key point is this: "The car’s drag makeup consists
of a 55%– 45% split between the pressure and the viscous drag respectively."

Makes wetted area (a point I made in another thread) pretty important!

Interesting paper. I'll have to spend some time with it.

CFD/FEA [is greater than] 'rules of thumb'.

[freebeard]

Simulpost! Interesting...

1) I doubt one person in a 100 understands that as a negative reference to The Template. That's why I am as unsubtle as a sledgehammer - otherwise people don't get it.

2) When I said that "To be honest, I think the huge underlying issue - that I am afraid you, Freebeard are a strong part of - is that speculation has become largely the culture of the group. To be blunt, posters just guessing" I'll cover in a new thread.

[freebeard]

1) Poe's Law. So, we can agree to agree then?

2) Thanks for the strong part part. Not all of us can throw down for a bead roller, & etc. Personally, I use Ecomodder as a substitute for social media. I have enough trouble covering car insurance on a fixed income.

I split my travel between (free) bus rides, my bicycle and whichever car is running. Seldom exceed a 15-20 mile radius.

I'm sure sgtlethargic thanks you.
