Wind resistance could be used to power a generator, but it would need to be deployed during breaking, so an air duct would open to allow air through a restricter with a turbine for generating power. My guess is brake-based regen is far more efficient than air based regen that it wouldn’t be worth the effort.

Heating in an ICE vehicle is a byproduct. There's no cost difference to using it or not using it.

Well it really runs more off parasitic drag (the alternator, compressor, etc) than gas but yes indirectly you are correct.

My point is it is unfortunate they can't figure out a way to power this on some type "renewing" energy or force when driving. The vehicles that use a heat pump for heating and cooling do this to some extent, similar to how an ICE heats as part of the cooling system of the vehicle.

Completely get the small generator option, which was why I was thinking more of a wind driven generator in some type of forced air situation. With no technical knowledge it makes sense, but I also understand the drag probably reverses any real gain. Wishful Physics I guess on my part.

Heat is a byproduct of EVs too that is captured through Tesla’s Octovalve. EVs are much more efficient, so there is far less wasted heat to use for cabin heat, so if someone has the heat on blast in the cold then yes it will decrease range.

While I don't doubt the fact efficiency can be gained on a EV through better heat mgmt, I'd take any positive Tesla news with a grain of salt when the article is followed by a Tesla referral code.

But yeah, apart from these gains there are no physics-bending way to run ancillaries. Any energy has to come from somewhere, just like it does on an ICE's ancillaries.

I do wonder whether a steam turbine would make sense to generate electrical power on an ICE, since 60% of gasoline's theoretical power is dissipated.

I occasionally consider truck camping. It might be fun to put a camper too on the bed of my old F150. But my boss would never let that happen. Minivans? I don’t think so.

Edit. Wife and I have concluded that, given where we live, driving 1000 miles to get to the beginning of interesting stuff is not fun.

So, the plan is to fly/rent/drive from here on out.

I'd probably consider the Lexus LM more "gaudy" than "ugly"
IMO that just means its ugly but in a more prestigious manner, appealing to folks who have more money than taste. Not to say the LM ISNT ugly (it looks like a bus...that new look Lexus face grille is far too tall in this application)

Something like the Pontiac Aztek is just plain ugly, and that's because its got no redeeming qualities over any other standard CUV that's worth overlooking the face. Even BMW's pignose on the new 4 series. Every time i look at it i CANNOT get used to it. Its one of those designs that i thought over time it'll grow on you or you get used to it...but i just cant....its just...godawful.

love too journalism

That’s staggering and speaks to not only Tesla’s mastery of battery technology, but mastery of innovation. This is not an electric vehicle improvement, a motor improvement, or a new battery chemistry. Rather, it showcases Tesla’s willingness to tackle and become the masters of a completely new competency to improve its vehicles

In the Tesla Model Y, the heat pump was a true engineering marvel. Elon admitted on the podcast that he has a trophy rack of impressive tech his teams have come up with in his bedroom at home. The new printed circuit board (PCB) for the Tesla Octovalve was so impressive to Elon that he added it to his bedroom trophy rack.

The word you're looking for is laziness.

We had a company approach us like 10ish years ago about making an energy recovery system that would work with one of our units with a 6.5hp Honda general purpose engine. Basically a generate and immediately deploy hybrid system. It took more power to generate energy to move the unit then the engine produced

So next time you pass a wind farm, imagine sticking that large of a flat disc of material up on a stick in a windy area, when I can't even hold a 4x8' sheet of plywood up in my driveway!

You've probably seen the size of the buried concrete foundations of those things. They are immense.

And they quickly feather the blades in strongish winds.

Years ago, before I got an engineering degree and learned to calculate stuff, I had read something about an ICE with extra steam powered stroke(s) or something along those lines. No idea if it made any sense or even if it was a real thing.

Well the theory behind it sure makes sense, but there are a few hurdles I can already think of, like:

-some ancillaries like the water pump or AC need to start running as soon as the engine starts up, they can't wait until the engine warms up and builds steam pressure
-you can map the alternator to only work in braking situations, which is a far simpler solution than a steam turbine

However, using a steam turbine to charge a hybrid battery that provides power assist would make sense on paper, and could provide a mileage boost to closed-circuit hybrids in situation where they don't use KERS, such as constant-speed highway driving. The only research paper I could find on this is from Egypt and is 20 years old so it's either super-duper-confidential, or not something being worked on.

It's likely too late for an idea like this that only provides marginal gains, in a world where PHEVs and BEVs will soon take over.

My guess is the latter lol.
