Smoking with a filter has no health benefits. Statistically, there are even more illnesses with people that smoke with filter cause they on average smoke more cause it irritates the throat less.
Our local cancer NGO even lobbied to ban filtered sigarettes as they cause more smoking and are plastic litter.
Pure aluminium is only used when you need to have very little reactivity.
General construction steel has >98% weight iron. Around the same as most aluminium alloys.
I think there was a Renault that worked like this. I think the main issue is that you need a decently sized battery that can supply enough power or else the ICE needs to start every time you hit the gas pedal like was the case with the older Prius models and then you might as well connect it to the wheels and you can have a smaller electric motor.
But batteries keep improving and you can pull more power per kWh now. Maybe with solid state batteries this power train could become the more affordable option.
There is rockbox that is an alternative firmware that adds every feature missing by default
There is pCloud which is based in Switzerland which has mostly the same regulation as the EU. They specifically state that they won’t use your data for commercial purposes. Until the company merges or gets bought I guess.
Ofc if it’s not end-to-end encrypted and all open source and self hosted, you can’t really be sure.
That is true. I do think we should retire pure ICE cars as soon as possible. If you need to do long distances, a hybrid that could be converted might be a good intermediate solution. If you only need a car sporadically, a car sharing platform with electric cars is a good solution. These already exist in big eu cities. Ofc good and adorable public transport is nr 1.
Decreasing the amount of cars would decrease emissions short and long term more than the current shift to EV and would make shifting easier as there are just fewer to replace.
I put very minimal calculation which at least puts it around the same order and linked a report by Volvo where they try to count the whole cycle of a car with the emissions of the production and transport of used parts and fuels.
On current electricity mix, an electric car is only slightly better on a CO2 emissions. With only renewables, it can be 2x better.
But the statement that in China it’s at least better than a Prius is just wrong. Until renewables take a serious share of the grid, a smaller well engineered hybrid is not worse.
A Prius will definitely pollute less than the typical SUV electric cars on a coal grid.
Cause:
Efficiency of coal power plant and all losses are as bad as ICE cars. The EVs do thermal->mechanical->electrical->grid->battery->wheels and if you count them all up, is not better than an EV
Prius is designed for low drag unlike an SUV
Prius had regenerative braking like an EV
But just the numbers:
Prius is rated at 94g/kg
Coal 950g/kwh
Volvo c40 0.2kwh/km or 190g/km even without losses
I took Volvo cause they published a report with a good compare ev and ICE https://www.volvocars.com/images/v/-/media/market-assets/intl/applications/dotcom/pdf/c40/volvo-c40-recharge-lca-report.pdf
Even with the current EU energy mix, it takes 77’000 km to be better than ICE, so arguably better. On coal electricity, they are worse. And this is comparing equally sized cars, a Prius will do better.
Coal power plant efficiency is less than 40%. You’d also not get 90% of the outlet on the wheels. There is also a lot of loss on the grid, but there is also on the production of fuel. The two pollute almost the same.
Burning coal however is a lot worse for the air quality.

I would turn that around cause you are claiming filters help prevent cancer. Producers should prove that, but they don’t. Filters don’t help.
Good for you, but you are in the minority. I know no one that smokes that carry around a portable ashtray. If there is none in a couple of meters, they get thrown on the ground.
