Tasers and combat avionics systems need cobalt, too, but never seem to come up as often.
I’m guessing because most people don’t own those?
Pfft, amateurs.
I mean, let I checked, I didn’t have a combat avionics system in my jeans pocket.
Not with that kind of attitude
Gotta play the blame game. Its our fault they exploit foreign children because we don’t use the pay-rise they didn’t give us, to buy ethically produced goods they don’t offer, so that there is enough money to pay the slaves and quench their unquenchable greed.
If we paid them twice as much for their products, that kid wouldn’t see a penny more. They’d pocket the difference for themselves because the free market doesn’t fix shit.
One of many reasons why electric vehicles aren’t going to replace combustion engine vehicles any time soon. #biofuel
Thankfully cobalt isn’t cheap. The latest trend in EV battery technology is to move away from it
Either by using Nickel rich chemistry in NMC battery or ditching it altogether and replacing it by LFP.
That’s good to hear we need them to be adorable and not a gimmick
All cars should be taken off the road.
Tell me you’ve only lived in cities without telling me you’ve only lived in cities.
The closest city is 15 miles away from me. I do drive, though I’ve actually commuted by bike a few dozen times (thank goodness for ebikes!)
All cars should be taken off the road, and furthermore, everyone should live in dense housing in the city. I wish I didn’t live in the middle of nowhere, it’s extremely inefficient and a terrible use of resources.
I Live in a city and stuff is walkable but having car would be great to for flexablity and convenience
It’s going to be hydrogen cars in the long run. We need a zero emissions vehicle that doesn’t depend on rare or limited resources. That inevitably takes us down a certain path. If not hydrogen directly, then something made from it like synfuels.
Hello handsome, why the ping.
BaldProphet is trying to pull a “gasoline is actually better for the environment” BS, ignore him.
Biofuel is not gasoline. Gasoline is a nonrenewable petroleum product. Biofuel is a renewable clean burning ethanol or methanol fuel made from grain or wood byproducts.
There are not enough rare earth metals to replace combustion engine vehicles with electric vehicles, let alone enough to replace the batteries of said vehicles. Electric vehicles are not sustainable.

Can you explain how this works?
Only part of the reason petroleum products are an issue is because they are nonrenewable. The primary complaint is that their combustion produces CO2 (and other greenhouse gases like NOx).
Ethanol, methanol, and any other hydrocarbon that undergoes combustion produces CO2 (and other gases). That’s how combustion works. For example, the combustion equation for methanol is: 2CH3OH + 3O2→2CO2 + 4H2O.
The only way around this while still performing combustion is by combusting hydrogen, where the combustion equation is simply: 2H2 + O2→2H2O.
Biofuel combustion still produce CO2, and I don’t believe at a significantly different rate than petroleum combustion, even if it does have the added benefit of being renewable.[1]
Yes, this view is missing a few variables. For one, biofuel production itself can be less carbon-intensive than oil drilling and processing processes. Biofuels can also be used to “recycle” other carbon-containing (waste) material. That being said, combustion is still the largest problematic factor at play here. ↩︎
Right, we’re not magically sucking CO2 from the atmosphere at a rate higher than we combust the biofuel.
The process is not neutral.
Absolutely. Compared to gasoline, it might be better. And if there were literally no other alternatives for powering engines, it could be acceptable. But there’s no point in taking “the lesser of two evils” when non-evil solutions do exist.
there’s no point in taking “the lesser of two evils” when non-evil solutions do exist.
Do they, though? How much rare-earth metal is mined ethically? How much of it is controlled by “evil” empires (China, Russia)? How can hydrogen or electric vehicles be made cheap enough to be sold as non-luxury vehicles?
The fact of the matter that is, until non-evil solutions are actually designed, switching from petroleum fuel to biofuel shouldn’t be overlooked. Ignoring biofuel in favor of non-solutions like electric and hydrogen vehicles isn’t going to slow down global warming. We’ll just keep burning oil instead of much cleaner biofuels in the meantime.

That doesn’t make any sense to me, and it’s been awhile since my biofuel class but I don’t think that’s true.
The carbon in the combustion product comes from the biofuel, the biofuel comes from plants, the plants get the carbon from the air. Therfore, by definition, every gram of Co2 released by combusting a biofuel came originally from the atmosphere.
It has to be neutral, otherwise where is the magical extra carbon coming from?

It’s currently unrealistic because of the difficulties of recycling li-ion batteries. The reason lead-acid batteries are recycled is because it is such a simple battery.
Another factor is the components in lead-acid batteries are very stable. Compare that to the incredibly reactive materials in lithium batteries.
