@sir i like that it hasn't got the gamification going like github with star and fork counters etc.

@cereal time for some hemlock 🍷

@karl i think that matrix is a fine replacement for messengers (like you described), not necessarily as IRC replacement for huge groups. i don't really get the hate for matrix. most of the "bloat" is not matrix-the-protocol but clients or bridges. at least we have something federated with crypto now which non tech people can use. not perfect, but still better than the other messengers around.

@cybette maybe i should do that with my jolla 1 too :)

I already said it some time ago, but I'd wish that sailfish os would be officially supported on pinephone. Would be a really nice fit IMO and kind of the same feeling as jolla 1 with replaceable battery and back covers with features.

@freemo my wording should have been "renewable" vs. "non-renewable" energy. nuclear fuels won't last forever.

in germany we have about 13% nuclear, 40% coal, 14% natural gas, and 30% renewables (https://www.umweltbundesamt.de/sites/default/files/medien/372/bilder/strommix-karte-2016.png from 2016).

the conversion from non renewable to electricity and then mechanic energy is as lossy as just using non renewable directly.

there are more interesting technologies for storing energy than batteries, and i think if batteries are established as status quo, we will be stuck with that.

sidenote, coal can be liquified, which is in use at the moment, see https://en.wikipedia.org/wiki/Coal_liquefaction . it's really inefficient, but in south africa your car might be a "coal runner" ;)

funny how a rant while driving leads to such a discussion :)

@freemo my point is that most energy is currently produced using fossil energy sources, the conventional car directly (sans refinery energy usage) uses it. For battery electric it gets converted from heat to rotation to ac electricity to dc to chemical energy and then to electric energy again.

@bonifartius current _battery_ electric cars seem like letters of indulgence, only for greenwashing.
not eating meat and not flying would buy at least a few years wrt global warming. that seems to be too hard for people to do though, especially the not flying part.

@Demosthenes there would be much less requirement for developing infrastructure if only the fuel would be something like a liquid. as it is, battery charging requires bigger connections everywhere (including digging trenches, etc.), while fluids just are "another pump" mostly. there is no oligarch hyping that though.

@freemo i'm a bit short on time, so a bit terse:

as you have descibred the losses in conventional cars, there are losses in power generation as well. The only thing really generating electricity directly are photovoltaic cells, but only with an efficiency of ~20%. Everything else is heat to rotation to electricity, i don't have a good link, but nuclear is around 40% efficient. Then we have grid losses, etc. I don't know how efficient the charging electronics are, but there will be losses too. So its say 30% efficiency from the grid and 80% efficiency in the car. Which then hauls half it's mass in half empty batteries, on average.

I was talking about hydrogen electric, hence my remark that only asian companies can build that. It's not perfect either but at least hasn't the environmental problems associated with Li-Batteries. Hydrogen storage is a bit tricky, but it's not unmanageable either. Refueling takes a few minutes compared to charging over hours (or damaging the battery by quick-charging).

Storing energy of green sources as hydrogen is good as the energy isn't lost over time and no batteries which get worse with each cycle. Additionally it's rather easy to move it then.

Another thing which is interesting are synthetic fuels, but i don't know that much about it. Supposedly there are ideas to convert co2 to methane using electricity and hydrogen.

@thor there is 0.3% fat milk and it's an abomination. it's weird tasting white (i assume from proteins) water.

@freemo i'm primarily angry that battery electric gets pushed as if it is handed down directly by god. it's ok for things like renault twizy. for everything else it's inefficient because of the weight you have to move around. meanwhile diesel engines are rather efficient _and_ are durable. >200000 km are easily doable when they aren't abused. those diesel cars are now supposedly the work of evil and need to be replaced with new shiny cars asap (meanwhile air travel is fine and needs to be saved from the covid consequences..).

if hydrogen technologies were pushed, i'd be fine with it, but only asian companies seem to know how to build that 💁 hydrogen & green energy are a good combination, in part solving the energy storage problem.

a kWh costs 0.25€ here, so free charging is a big handout for people who are already wealthy enough to buy a new car.

random thoughts while driving: isn't it amazingly fair that people who can buy a new electric car (~20k-50k €) get

- sponsorship from the government to buy it (around 1k-5k €)
- free charging stations everywhere, because someone who shells out money for a new car can't handle the charging costs.
- nobody asks about the resources going into building those cars vs. just fucking use the old cars as long as possible.
- charging is done with fossil energy and no one cares because ELECTRIC!!11 YEAH!!!1

nero had a point i guess. just burn everything and have a clean start.
