Virgin lithium vs Chad renewed lithium

Literally they were talking about the car they already have, and their own experience of it being positive. They're not wrong or uninformed for liking their own car.

I also like my EV. It's the best car I've ever owned.

They'll only get better.

Consider if every home was heated with a co2 unit. In that case there would be a lot of potential leaks but since it's co2 it's not that big of a concern. The units wouldn't be as efficient but if all our electricity was produced with renewables it wouldn't really matter.

If every unit was R-32 than yes it might be more efficient but leaks could cause some damage to the climate.

Tough to say for sure which one would be better for the enviroment but I think end goal currently should be co2 heat pumps and solar panels on every well insulated house. Don't think we have a better set up enviroment wise right now than that.

Also electric cars are expected to last longer as they are much simpler machines compared to ICE cars

There are even tabletop EDM tap removal tools these days. When you're a new guy to EDM you might show up to work with a few taps to remove for a while on the old Sodick, but the guy on the big ass Makino isn't.

I take every chance I can to fight against that. There would have to be rules in place, like it can only activate inside the home and only record if there’s a certain trigger for example. This isn’t an easy road but if you’re fostering children then a certain amount of privacy rights needs to be set aside to safeguard against a heavily abused system. Just like you’re expected to be on camera if you’re in a store, you will expect to have questionable actions recorded and looked into.

To protect the children? Absolutely! Most of those kids have gone through enough bad to last a lifetime before they’re put in the system…whatever can be done to make sure the system doesn’t make things worse is great!

CO2 is better than other things GWP-wise, true, but it has no place in home installations given everything about it.

There is one place where it makes sense, system which accounts for probably most lost refrigerants while not caring about efficiency that much - car AC/pumps. And guess where they not actually use it forcing proprietary garbage 1234f...

So if CO2 is to be pushed for environmental reasons it should be used were power and efficiency is less of an issue than leaks, but hey, it's never about environment in the first place is it...

It'll make investing really easy and it will make gains more predictable. If there is no arbitrage opportunity because the market is so efficient, then all investments would be roughly equal and the only differences in return would reflect irreducible risk relative to the market.

All investing will be more profitable at the expense of the margins of high performing investors.

EU will force them, likely

Your calling for mass surveillance bro . That’s dystopian level shit.

Have you seen the type of people that are foster parents that this would apply too? They are not masterminds. Again, this wouldn’t be a silver bullet but it would be a step in the right direction.

There might be some legal hurdles for something like that but maybe that’s a right they give up when agreeing to be foster parents?

It depends on the future of course, but like how lithium first showed up in phones, then laptops, then larger and larger things - if something comes out to replace lithium in certain use cases, say iron batteries for grid storage, then all that lithium can be recycled back into the mix.

Or if there's an expensive but newer medium that starts going in phones, then tablets, then laptops, then power tools, and so on - all those batteries get recycled back into the lithium pool

I am a red seal refrigeration and AC mechanic with 10 years of experience and I own my own HVAC company. I'd like to think I have a pretty good understanding of heat pumps.

I merely stated the purpose of using co2 over other refrigerants, I don't think you can argue co2 has a much better gwp than alternative gases.

I agree houses should be better insulated first before installing a heat pump. There is no high temp or low temp heat pump, I assume you mean installing a heat pump with higher BTU capacity vs using a smaller system.

A COP of an electric heater would be about 1. I've never heard of a heat pump with that bad of a COP lol.

Surely you know R-22 was considered a better gas than 410-A yet we switched for enviromental purposes. It may be the case that we do it again. It's not that big of a deal and I'm not really sure why you seem to hate the concept so much. Even if a co2 unit is less efficient the net effect on the enviroment is probably going to be positive, especially if we can focus on solar and other clean ways of producing electricity.

To me the interesting idea is industrial uses.

Take steel making for example, you have molten iron at one stage, then at a later stage you water cool it.

With further engineering you could pump the heat from the water cooling stage to heat the container of molten iron.

Obviously we're a far way from using heat exchangers to melt iron, but the point is if you can work out something like a preheat so you're heating the iron to 200F before melting it you can use a lot less energy, plus you save energy and water from the water cooling process.

So if you could reduce energy used in steelmaking by like 10% and water by 20% - that would be huge globally.

He was the first that I heard mention that we are not overpopulated. He may not have originated the idea. Or maybe. The collective unconsciousness and how multiple people around the world get the same idea at the same time. But researchers agree, aliens.

We obviously are, considering it's /r/futurology and predictions about the future are inherently a what if game.

Or it solves some of the issue of "what do we do with the salt after we desalinate" making desalination for drinking water more attractive.

I've seen shops have an old edm for burning taps out of things.

>Supercritical CO2 heat pump

This is a good article describing what is a sCO²

To be fair the Gulf is already a toxic waste zone thanks to BP, maybe it's better to drill there than Alaska?

If we are playing the what if game. What if more technological advancements are made?

Thanks Elon?
