As far as I know they are equivalent density to LiPho, I don't know how they do it but it should allow similar range to existing current Li-ion batteries.

CATL and BYD have already shipped the Sodium Ion batteries that cost nearly a third of LiPho and half that of Li-ion at similar densities, you can buy cells and cars in China already.

They also both have cells and cars out next year with a 2x density Li-ion, it's already been showcased so we know it exists but it's not on sale yet. By the time Toyota ships these Chinese companies will have been in market with a comparable product for many years. Sodium ion will do great for existing range and replace LiPho for power storage and the new Li-ion will be used in high range cars and probably replace all Li-ion in everything where density is preferable to price.

I usually clean it with soap and water that has so far kept it clean and prints stick to it well.

Just add water to the final product.

It's possible to weaken it with less coffee to water ratio but it will likely mean a change to other parameters like grind size to get back to the neutral flavour you want because it will increase the water filtering speed. It's just easier for strength to add the water at the end.

We can't keep burning gas there won't be any in a decades time. We don't have any choice about storage of hot water or heating electrically and using water to store excess energy makes a lot of sense. However take a look at Sunamp they do a phase change material tank like thing which takes less space so you can get the sort of capacity you want.

Solar panels and batteries at the moment are paying back in about 7 years and that is without any government grant, you can potentially get it down to 5 with a bit more risk taken on with not tier 1 kit and installers. Or put another way you pay up front for the next 25 years to pay 8p a KWh (instead of ~35p).

Comparatively I can't make a heatpump do anything but cost more for heating over the next 25 years, it never pays off in its lifetime. An air to air heatpump however should be equivalent to a boiler but they cost about 1/3 of the to water ones which seem to be enormously overpriced compared to other countries that do something similar (Norway).

The heatpumps for heating water are crazy expensive at the moment. It makes no sense as they are a lot cheaper in Norway. However an air system with a few zones driven by a heatpump (air to air or ground to air) less than a third of the price installed and will also provide cooling in the summer with the same efficiency and replace all the radiators.

I think we are just being ripped off at the moment for replacements for radiators when air to air works just fine and takes up less house space anyway. Its worth looking into because the 20k heat pumps into water are not paying back in 25 years whereas you can maybe get an air to air to be neutral cost over its expected life time compared to a boiler replacement.

https://ourworldindata.org/emissions-by-sector gives a good breakdown of the worlds C02 production. Electricity and basic household use combined with transport are 73% of the problem. Livestock is 5.8%.

If every person on the planet installed Solar panels and completely removed their grid electricity and gas usage and replaced their car with an electric vehicle and didn’t use planes we could address 10.9% + 11.9% + 1.9% = 24.7% of all CO2 production. If we all gave up all meat then we could raise that to 30.5%. Its less than that however because only 60% of personal transit is actually passenger vehicles, not all aviation is people, some tiny amount of emissions for cement is going to be personal etc etc. That is the grand total that we have control over with personal replacement and some consumer choice and some of that livestock would go into other protein sources. The rest is all businesses and building and waste management that if we stopped using would no longer be developed nations and that we have no control over how its powered. Its fair to say business is responsible for reducing emissions of at least 70% of the problem.

I would also argue that there is no particular reason for consumers to be responsible for electricity CO2 production either when CO2 free alternatives exist, we might have the option to buy solar, wind and batteries but the grid is a better place to fix that in the same model so I think we could argue reasonable its even less we are directly responsible for. All of this is consumption for us and the economy, no people means no CO2 production but any CO2 we don’t directly emit (a car is direct as is a gas cooker or a wood burner) isn’t our fault its the business that burnt it to deliver that service/energy and we don’t get to control it so we can’t be held responsible for it.

The entire goal is to transition our lifestyles into something sustainable not to go back to there being 10,000 of us living like cavemen.

I did the maths on a variety of electrification projects and I can not make a ground source heat pump pay for itself in 25 years. The solar is 7 years and it should last 25 so that is easy, battery storage for power shifting is about 3 years and obviously good on the right tarrif so I did both of those. I think maybe an air to air heat pump could pay for itself but installation is expensive and I have no idea how many zones I really need.

We will take a large chunk of the planets life with us. I don't think we can destroy it all however, the planet will get to intelligent life eventually.

I see a variety of miniatures have appeared on thingiverse, I see them in new top 7 days quite often. They never have a name with Warhammer or Space marines in the name. Instead they will use some generic name.

It made some sense when they came in physical format and there was a real risk of a highly sought game selling out. Nowadays they have put worthless digital incentives on preorders and they can't possibly run out.

There are open source operating systems that are Android based which will update to the latest versions and fix bugs and suchwell beyond the manufacturer's support, lineageOS for example.
