It’s better to use Whonix or Tails if you want to use TOR browser securely. If I ever had to use Windows again it would not be for anything private.

I'm certain there are people who use Tor in a way that it would make sense to use a secure OS.

But I use Tor to get around stupid public wifis and suchlike that have content blockers. I'm not scared that the police are going to beat the shit out of me so I just use Windows or Android.

Only if you remembered to put water in it and happen to want hot water at exactly the same time. Besides, a normal kettle boils in a minute so it is hardly difficult to just flick the switch on the kettle on when needed. Certainly less effort than fiddling with some app.

LIDL is selling a bunch of "smart" crap this week including a "smart" kettle. According to the blurb "Can be linked to the Lidl Smart Home System using your WiFi connection". And I'm thinking yeah and what possible reason ever would I have for needing that? And the same is true for most smart products.

in the Ellipsis. dropdown menu you should see an "Add to home screen" or "Install" button depending on what the website says in its metadata. The latter is for sites which have webapps.

I only use Android so I don't know. Check the menu and see if you have add-ons and you can install uBlock Origin. Edit - it looks like thanks to Apple being Apple, Firefox on iPhone is a wrapper around webkit and doesn't support add-ons. Maybe you could still make a launcher though I don't know.

This won't help in the above case so it's a little off topic. But I got rid of Twitter on my phone and still use Twitter on my phone - Basically you just open twitter.com in Firefox, and go to the menu and click "Install". Now you get a launcher icon to an "app" but it's just the website hosted by the browser.

Instantly saves 150Mb, stops it doing evil shit and because it's hosted in Firefox I get to block all the ads.

I would advise doing this with any app which has a desktop / mobile version and see what happens - Facebook, Reddit, LinkedIn etc. Some social media sites will nag you to install the app but some won't or will be functional in spite of it.

I don't even know where to start with that.

It's more complicated than that. Hydrogen has a higher energy density than gasoline on a mass basis (i.e. 1 kg of hydrogen is about 3x the energy density of 1kg of gasoline). But for volumetric density the situation is reversed - 1Kg of hydrogen takes 4x the space of 1kg of gasoline. So you're not really saving anything by using hydrogen.

On top of that gasoline is a liquid at atmospheric pressures and can flow into any nook and cranny of your aircraft. Most aircraft will store fuel in the wings and under the fuselage. If you use hydrogen you have to store it in heavily reinforced pressurized tanks, preferably spheroidal, cylindrical, toiroidal in shape. That means you're looking at putting some honking great cylinders on your aircraft and there is no convenient place to do it. They'll either have to be mounted on struts or in the body somewhere.

I don't think batteries will find much application in aircraft until solid state batteries come along. But there are some high density batteries appearing for aviation applications (drones, taxis etc.) and just like with gasoline they can be incorporated pretty much anywhere in the structure of the aircraft.

Notably they trialled first for coeliac autoimmune, but it'll be 2024 before phase 2 results are out for that. About 10 years back there was a similar vaccine which also passed phase 1 trials but failed at phase 2. Phase 1 is basically testing that the vaccine does no harm in small groups and it is phase 2 where they measure if it is actually efficacious and to what level. If it passes phase 2, then get your hopes up.

Except it does. This study suggests that the plants that produce hydrogen from fossil fuels are only capturing 80% of the CO2. So 20% is emitted. And aside from that hydrogen has the potential to contribute 12x as much to global warming as CO2 emissions.

Unless someone figures a way to sequester hydrogen into an inert, reversible form you really don't want to be stockpiling hydrogen for obvious reasons.

1. Not really. There are plans for hydrogen plants. The vast majority is "blue". Secondly what are the chances that an oil company is going to make green hydrogen?
2. The renewables aren't the problem. The cost of capturing energy is the problem. If hydrogen takes 3-4x the energy then that's 3-4x the land with 3-4x the solar and/or windfarms at 3-4x the expense. Do you not see the problem?
3. No it isn't. Scientific studies suggest the impact on the atmosphere might 12x worse than releasing CO2.
4. Lithium isn't the only battery material. Nor I daresay even if it were, that the safety risk is anywhere near as bad as driving a train with a hundreds of kgs of hydrogen on board
5. Lithium isn't the only battery material. There are numerous battery chemistries in existence. It might even be that some less dense chemistries like sodium ion would be viable.
6. Which is why I clearly I suggested a progressive approach. Switch from diesel to biodiesel, start building hybrid trains where the motor and tender are almost separate things and where the source of power can be 2 or 3 potential inputs - diesel, electrification, battery. And where rolling stock can use solar to reduce consumption further.
