Front brackets - much less movement

Much less movement than what?

I don't know what the legal requirements are in the US, but I would suggest using Niloc nuts, instead of plain nuts, on the bolts restraining the springs.
Personally, I would also use a washer between the nut and the spring.

Of course the correct 1/2 nuts will be used I have many to buy. I'm still in the early stages of collecting parts.

Am I crazy or smart??

My bumper is mounted behind the rear storage box a few inches. There is a swing away spare tire carrier on that bumper. The tire is mounted close to the hinge, on the right side.

Due to the mounting position of the bumper, on the left side, is a space 18 inches deep by 12 inches wide, with nothing there. As the storage box is 1600mm wide and the habitat is 2200 mm wide.

Expedition vehicles with a 12 foot height and 2200 mm wide create air turbulence in the rear when going down the freeway at 60-62 mph.



Am I crazy to mount this wind turbine in the space 18 inches deep by 12 inches wide?? This produces 12 amp output while driving.

Maybe at best 12 amp in clean smooth airflow. Turbulence, 1/2 - 1/3 that, so is all that monkey motion worth a maybe 3% boost over your equipped engine alternator?
And weren't you planning on adding a second alternator anyway?
BUT are you also planning on mount that on a extendable 30 foot pole so you can wind generator power when stationary while camping?

Thanks for the comments. No pole for stationary use.

No second alternator. (too many problems - do a deep dive to discovery them)

Amp output is unknown. But this is free energy while driving.

Fewer gadgets, less weight, less stuff to install, less stuff to maintain, less stuff to buy, less stuff to break, ad infinitum.

There is no free lunch

That has been my focus.

Yet there are trips when solar is not viable.

Not quite 'free'. It seems $320 Alibaba to $596 Amazon, so would those $$s be more productive using for more energy effect equipment, giving a better ROI ?
But I'm all for you giving it a shot. We need trendsetters, perhaps it will turn out to be the go-to add-on.
Although I'm not sure if even if it turns out to be the go-to add-on, I would run it on my truck. I'm afraid that I would look like the 'Adult-Expo' version of this going down the road

If, as I expect, this wind turbine is not built to deal with vibration, it will simple fall apart if fitted to a vehicle.
A DC/DC charger powered by the alternator would likely give you more reliable power at roughly the same cost.

The standard alternator for the Isuzu range of N series trucks, is 2,160W of power; which is a substantial amount of grunt. Allowing for losses I would suggest the maximum under normal circumstances would be around the 2,000W mark; which is still reasonable. But doesn't account for air conditioning/heating fans, lights and such like power drawings.

I have seen quite a few wind turbines on properties in the middle of nowhere, in general what I have seen requires wind of around 5ms to get going and they start to really work from around 10ms. 90km/h wind is 25ms for reference.

Assuming you are using 12V as a reference, then 12A x 12V = 144W with a best case scenario. Unless it is somewhere over 3m in height on a pole and free from any trees, buildings and such obstacles for a bit of a chance to pick wind, I would suggest you may get some peaking wattage around the 50W mark of generation.

If you are stuck somewhere with bad weather with almost no sunshine, then a wind driven generator should be able to sort of hold your batteries from heading to zero.

I think this tread turned into a debate for dc-dc charging which I do not agree with. (works great for lead acid batteries, terrible for lithium)

My purchase price is $200 with the freight and controller


Dc-dc charging runs $700-$1000 if you protect alternator overheating correctly - (many folks ignore it)

Everyone is entitled to their own opinion.
Case in point... my opinion definitely differs from yours.

The safer way from the alternator, is:

Buy 2nd lead acid battery, Use 1000 watt ac converter. Plug into the shore power outlet. (no alternator overheating)

That's your opinion, and you are welcome to it, but I don't agree with you.
As I have said before... it's your build and you can do whatever the hell you want.
