I have. I would probably use my last phone for at least another year if it didn’t loose system updates. There’s too much important personal data (bank, photos, messages including medical info…) on the phone to risk using it unsupported. At least to me it is not worth it so I try to buy a phone with reasonably long support and buy a new one soon after the old one looses support.

Cars are also not safe, especially at 200+ km/h but somehow it’s OK to drive them this fast in Germany.

Edit: What I want to say is that there is no absolute safety.

Unfortunately use of fossil fuels also continues to hit record numbers year after year.

I think it’s an error. It’s should likely be Nissan Quashqai. Or Hyundai ix35/Tucson.

You basically need a few conditions to be met to make this useable: tide needs to be high enough, there needs to be suitable geological formation that enables building of such power plants, it has to be publicly acceptable to build there, and you need to connect it to the grid. The last two can especially cancel eachother out.

However, this assumes you use potential energy. What you are envisioning might be more like current power (so kinetic energy) where I’m not sure what the limitations are. Perhaps it’s not too practical to build huge plants underwater in locations with relatively constant current and connect them to the grid

Hehe, I walked right into this one. You’re right. I totally failed at trying to be a smartass.

Why are you comparing fossil fuels and nuclear “per tonne” that makes no sense. You replace tens of tones of nuclear fuel per year any you burn millions of tones in a comparable fosil fuel plant.

And regarding the carbon emissions from enrichment… Just use nuclear to power your enrichment plants. This way your emissions are extremely low because you don’t need much fuel and you use nuclear energy to produce nuclear fuel. French example: https://en.m.wikipedia.org/wiki/Tricastin_Nuclear_Power_Plant

With energy positive here I mean useful energy positive, so electricity or high temperature heat.

You are technically wrong, the worst kind of wrong :)

DT and DD fusion reactions release energy. More energy than is put in. It’s the whole system that hasn’t been energy positive. We’re close to breakeven in terms of plasma (heating power vs fusion power, and it’s not like heating power is lost from the system it still heats the reactor) but to be useful fusion power needs to be >10x heating power so the whole system is more than self-sufficient.

I wonder what the round up efficiency is like.

Generally for extended periods you would pedal with something like 100 - 200 W while small electric compressors seem to be in > 1 kW region (and don’t get tired as quickly :D).

So basically with pedal power you could feasibly run some led lights and portable electronics but anything beyond this is not practical.

(Established) scientists have a long history of ignoring new theories not science itself. But that’s because at the end of the day scientists are still human.

Science is not great at working on a very short time scales. But give it enough time so more evidence is gathered and possibly some stubborn influential people (that can’t accept a new theory) die and generally we get closer and closer to truth.

It all depends on what is actually trying to be communicated. With your definition most meals would be plant based so why even bother to say it. With definition where plant based means no animal products it communicates that it is fine for vegans and it’s likely less offensive for people allergic to word “vegan”.

Language is interesting in this way. Same words in different contexts mean different things.

“Based on true events” = “Contains traces of what actually happened”

“Plant based” = “Does not contain animal products but can contain mushrooms even though they are not plants”

Homo sapiens also doesn’t originate from Europe.

How far back does it count? Humans originate from Africa so everything we do can be seen as Africans doing things with stuff from all over the planet. Or perhaps even that is not far enough. What’s the origin of the first mammal… The only contestant is change and life is good at mixing things up.

There’s also survivorship bias. All the crapily designed cars from 30-50 years ago are long scraped while some of the well designed ones are still around. With “current” cars you see the whole spectrum.

Indeed. It takes time.

And there needs to be an actual alternative to driving. You can’t just make driving worse and expect results. I’ve found that even small positive changes in alternative methods of commuting can have disproportionately positive effect. For example at work we simply installed better and more bike racks and it seems that after a while we have maybe twice the number of people regularly cycling compared to before. Basically because cycling accommodations got nicer a few more people started cycling and then others saw that it is not only feasible but also enjoyable so they started cycling… If we could only fix few sections of the road leading to our facility… Once can dream.

But yes, change takes time.

Mysterium - something easy to learn and can be played by up to 7 people. One of the players is trying to tell others (psychics) who their killer is using very nice looking but rather ambiguous cards.

Maximum apocalypse - up to 6 characters doing different missions in different types of the apocalypse (zombies, nuclear war, aliens, robots). Map is randomly generated so even though there is limited number of scenarios they are replayable.

Sherlock Holmes consulting detective (multiple boxes) or Bureau of investigation - investigation in Arkham & elsewhere. These are text based puzzles (e.g. solve a murder case).

Spirit island - it’s basically anti Settlers of Catan :) Still learning to play it but so far it seems like an amazing game with many scenarios…
