race action: World Solar Challenge and aero
 
Here's some footage, illustrating the challenges for extremely light aero structures under racecourse conditions

Now that's real eco-modding.

And relevant to this thread: ecomodder.com/forum/showthread.php/why-dont-cars-have-wings-partially-take-weight-39409.html

Yeah. It's tough to watch the crashes knowing the hardships all team members endure just to participate, all their work lost in a moment.
The importance of coefficients of adhesion and implications of compromising lateral acceleration g-forces which can be sustained at the road interface is really rammed home.
I tip my hat to all of them. They're the stuff that Tesla's made of. Literally!

LOL, I was just going to mention that this is evidence for why cars aren't airplanes.

Don't know why the embedded time skip isn't working, but skip to 11:48

That's an interesting challenge.
I wonder if we could assemble a team ecomodder :D
There is quite some room for improvement to be seen on these vehicles and their driving strategies.

I would believe their aerodynamic theory is a bit in front of even Aerohead, or Julian. Most schools have compute power that dwarfs anything I see here. They definitely have a better manufacturing support system. But we're experienced. Hmmm.

We wonder if you could assemble a team ecomodder.

...and campaign the length of Oztralia.

The most I have seen is springing for an hour of wind tunnel time in Utah.

Piotrsko -- I've given it some thought.

Just slap some panels on it.

We're experience eco-drivers and even making it all the way would place us better than many of them that do not finish.
I've also seen quite a few things there that are inducing way more drag than they need to.
Especialy the hard transitions on the catamaran designs are inducing quite some additional drag.

That design might be very areodynamicly optimize, but it lacks the optimisation to generate sufficient power.
There isn't realy any good place to mount the solar cells to it.

But we would likely have untill 2023 to come up with something as well as building it.
