"simple challenge" :) AS a designer and manager in an R&D facility for a major multinational developing highly complex electronic devices let me assure you it is not "simple" unless you make it easy and by sealing it you've lost that option :)
It's the physics of the wind motion not the devices :( and how that motion affects the devices ability to operate NOT how they affect the materials.
Unless you are envisaging ultra fast surface shape modification materials capable of altering physical shape in sub second times ? THe most advanced aerospace divisions are barely scratching the surface of being able to do that much slower on the most expensive research planes wheih are much larger than a blade :)

How does the new Citroen Cactus 2L concept fit in this debate?
and welcome back Peter...

Is it using the Peugeot system ? IIRC its tank empties in less than a 1km of driving so pretty much it's being used as a transmission rather than a drive I think :)
Mind you given past experiences with leaky suspensions do you want to trust Citroen with anything involving gas or pneumatics :) :)

they only leaks I ever had were the radiator or the airco, so yes, I trust them.

Well, let us avoid from unnecessary complexities. The primary reason is what I am talking about, has been done before, and I mentioned the example: Rinspeed sQuba. :rolleyes:
If it could maintain its electronics while being driven under the water, so my concept car can do a similar task while saving the inner vacuum, inside its solenoid tubes.
We just need to do more elegant tests on one sample of Rinspeed sQuba to check what are the exact differences between leaking water inside its components, and leaking air molecules outside them, by measuring the air pressure, etc. Therefore, the degree of the current sealing would be identified, so we should focus on improving it then.
Also, it is desired to harvest more electricity from produced heat during this process, if the involved elements could offset their weight, in the energy economy discussion, as it was pointed out before.

Matthew (DBR9), I see your messages in my inbox, but there is a technical error in here that my replies to you cannot be sent. I ask admin to fix this problem please. I suffer from this situation for months.

P.S: My next post on wind affair is going to be sent soon.

I didn’t mean this approach at all. :eek:
We can inspire from constructions’ solutions to deal with this issue in tall buildings. Also I said:
[I]Even some parts of this system can be embedded under the ground, for safety, maintenance, and efficiency considerations.[/I]
For instance, the intake section can be mounted on top of an oriented cement platform (say a 3D trapezoid). It is made of steel walls that are movable down into the body of platform, when wind gusts are too strong & harmful.
It can be considered to make some cement wind tunnels to pass the captured wind and funneling them through a tapering passageway that naturally accelerates wind flow in a several-meters path in depth of e.g., one meter under the ground.
When the powering operation is off and the electronics are sealed from other parts of this configuration, by running water through these ex-wind tunnels, we can cool the road & chill the passengers, suitable for hot areas; similar to the mechanism of the natural ventilation in buildings by windcatcher, a traditional Persian architectural element:

I think the above points can be useful for the opinion you stated. I don’t insist only better materials could create a miracle.

One trick to make a kind of shield against the electromagnetic fields of inductive coils in smart roads, is inspiring from modified cars.
Two examples are:

Let me bring up three examples, showing the usefulness of modifying the body. I mean that would bring further benefits, if one applies the solenoid electricity approach, on the electric vehicles.
[COLOR="Blue"]At first[/COLOR], there is this “[B][I]Mini Cooper Countryman ALL4 Racing Dakar Rally Car[/I][/B]” having two properties which drew my attention: 1. Water-cooled brakes (so it’s clean, I guess). 2. Using fluids inside shock absorbers & fluid reservoirs, considerably.

[COLOR="Blue"]Secondly[/COLOR], take a look at “[B][I]2015 Toyota Camry Dragster XSE with 850-Horsepower[/I][/B]” that its tube-frame chassis, pretty excited me about method of solenoid electricity in my proposed car.

… and [COLOR="Blue"]thirdly[/COLOR], there is this “[B][I]Polaris Defense DAGOR[/I][/B]” with a XP-style chassis design, plus a special body to make the whole vehicle ‘Light Weight’. Therefore, this emphasis shows the solenoid tubes do have such an importance to reduce the car’s weight.
Also, it has modular design & a great suspension system.

[CENTER][url="https://youtu.be/8cyJnoRCGtA"][B]Car Doing Front Flips! Dump But Cool ;-) - YouTube[/B][/url] [/CENTER]
Recently, I saw above video that made me think about applying it in my plan.
I think adding such a cage which prevents the car from flipping over, could be a good idea.
Not only front flips, but it can be generalized to lateral sides, something like a spherical / oval frame to bring more safety (leading to a safe rolling) & other kind of crashes; plus producing more electricity, as it was suggested via using solenoids & magnets.
The main flaws for this mechanism, are reducing the beauty of the car, and taking up space around it; so those flaws might be fixed by telescopic tubes, embeddable into the body.

save budget
Well . i thing one of the benefits of using a hydraulic hybrid system, according to EPA claims, are a 60%-70% increase in fuel economy (based on lab tests), a 40% reduction in CO2 emissions, and a lower "hybrid penalty" costwise, which can be recovered in as little as three years due to fuel savings (1,000 gallons of diesel/year) and reduction in brake maintenance costs. So it will be more eficcient than before. Right?

Wrong.

These numbers seem too much optimistic.
The hydraulic hybrid system is surely great for some special cars: big cars that stop a lot for civil purposes such as post, delivering packages and cleaning streets; school bus, …
However, the core of this idea is just bright, inspiring, and effective. I believe an integration of hydraulic hybrid system and [URL="https://en.wikipedia.org/wiki/Kinetic_energy_recovery_system"]KERS[/URL] could / should give momentum for any clean car at many moments in some points.

Recently while reading the news, I ran into some breakthroughs in making chassis, composed of different materials.
These cases may be inspiring to promote the idea of ‘active chassis’ which is going to give important contribution to generate electricity, definitely via piezoelectric effect.
