Your body now emits 5000 becquerels, which is around 70 becquerels per liter of your body. So that Fukushima radioactive water is only 2-3 times more radioactive than you.
That is why 20 Bq/L limit proposed by the ODWAC does not make much sense.
Apple is not just charging for payment processing, you get access to the App Store marketplace with more than billion devices. With Stripe you only get payment processing.
For the other fees discussed in this article, you do get additional capabilities. Distribution is not one of them, but it's not an apples to apples comparison.
They will not, whole process from water to hydrogen to fuel cell to electricity is very inefficient. You only get 1/3 of input energy back (if you use 100kWh to make hydrogen, you get back from the fuel cell 35kWh)
Not to mention hydrogen is a massive pain to store, to transport, and to convert to electricity.
Hydrogen fuel cells aren't ever going to happen. [0] Power to weight sucks, energy to weight sucks, and safety sucks among other things. The supposed advantages over electric cars (infrastructure, range, refueling, longevity) don't exist, and at current rates of tech development won't ever exist. But the disadvantages (complexity, hydrogen storage, inefficiency) still do.
That's ok, Ethereum is down to half of what it was a little over a week ago, Monero is also down to less than half of it's high price in the last month, etc. When Bitcoin has large swings up or down it tends to drag the whole crypto ecosystem with it.
Ethereum at $700 would have be crazy profitable 6-8 months ago, but it no longer is, due to increased difficulty. You might scrape a little profit there, but in June that would have represented ~$10 in profit a day on a 1080TI. Now it's maybe $2.
Maybe, maybe not. I've still got 2x machines running old 7950s which were mined with for over a year and they're running perfectly fine.
Gaming and general computing is such a low intensity activity - if they didn't break while they were mining I figure that they're comprehensively stress tested at this point and they'll run til they're too old to be useful.
The biggest problem that mining GPUs tend to all suffer from is fan failure. I'm speaking from experience.
Replacing a video card's fan is certainly doable, but it isn't nearly as easy as replacing a CPU or case fan (due to the fact that so many GPUs have custom fan setups).
Some of the GPUs (like Sapphire's) have fans which are easier to replace. These are not the norm. Also, being easy to replace doesn't mean they are easy to acquire.
Here is my take on it few years ago. I tried to make it more like magazine, and get article text and photo, and there is a section with only articles that reached top position.

Few years ago I created http://www.newswebreader.com (still functioning) website which is the web frontend for USENET. It has NNTP server in the background connected to other NNTP servers, and it displays groups, headers and posts similar to three pane Thunderbird.
You can create an account and susbscribe groups, it remembers what messages you read.
Idea was in the end to make frontend to USENET that would look like Stack Overflow, with voting, and your replies would propagate back to USENET.
