I don't know. If you are not already familiar with the inner workings of bitcoin, it seems to me that a simple computation power secures the transactions is not really helpful. What does that even mean, to secure the transactions?
Essentially, for an article that is aimed to such a wide audience you need to find an appropriate simplification. Such a simplification will never be completely accurate. Therefore, I consider anything appropriate that is technically not wrong and does not create more confusion. For example, describing mining as a process of generating bitcoins would probably satisfy those requirements (ignoring transactions fees).
I agree that it would be nice to be able to explain what the real purpose of mining is, but I don't see a really good way to do this.

Its daily electricity bill amounts to $39,000.
All from coal-fired plants.
Surely there's a better form of "currency" that's not so wasteful?

Why Blockchain Needs ‘Proof of Authority’ Instead of ‘Proof of Stake’ or ‘Proof of Work’

I love how they published a picture of the keys[1].

Why can't the proof of work be a series of adversarial StarCraft games or something? At least then all of these GPU cycles (is that the term with GPUs?) and power consumption creates something we can watch and be entertained by.
Why don't we add processors to water heaters and HVAC systems to do something useful with the heat generated by the processors?
It would require the silicon to run at higher temperatures than when air-cooled. Semiconductor failure rate roughly doubles every 10C temperature rise. For most environments, it's better to spend energy to actively cool the silicon than extract heat energy from it, because the cost of failures is higher than the cost of power.
I know you said air-cooled, but what about a Peltier cooler? Silicon stays cool, water gets hot, win-win.
I don't know if it's a frequency illusion or if a lot of people are playing with them lately, but I've seen tons of people mentioning peltier cooling lately.
I've been working on a design to cool my cpu with one. The best part about peltier modules is also the worst part: the cold side gets really cold. So cold you get below the humidity threshold, and end up with water all over your system. I'm trying to hook up a bunch of humidity, and temperature sensors to an arduino that will regulate the power to the peltier module to try to only let it get as cool as the relative humidity will safely allow.
What I'm getting at is you could do it, but a peltier cooler would need to be manufactured for it to be reasonable at the scale they're looking for.
Separate from the condensation problem they use a LOT of power. They're not terribly efficient, which would likely defeat the purpose. ( https://en.wikipedia.org/wiki/Thermoelectric_cooling#Perform... )

I remember them being used for "extreme" overclocking.
Nowadays people in that department seem to have moved to the elegant solution of manually pouring LN2 on to a cup that sits on top of the CPU (or GPU).
How about water cooling?

I would rather it be put to work finding genome sequences or something.
probably because it's slow to verify and the difficulty is not readily adjustable
Slow to verify, sure, but difficulty is definitely easily adjustable. Just scale up the game map and number of units, suddenly you have a larger search space for navigation and more AI objects to manoeuvre, too.
hmm, fair point, but i'd have to see proof that the difficulty is linearly adjustable with 256 bits of granularity
Make a pull request =)
Funny bloomberg just made a video about this mine.

Ah so that's who was using my "new" ASIC before Bitmain shipped it to me
Looks like unintended consequences of the worst kind to me.
Interesting... there doesn't appear to be any fire suppression systems pictured in the mining buildings
Those office chairs need a re-think. It would crush my back to sit like that for a shift.
However, I always find it sad to see how mining is depicted in most media: as a way to "generate" bitcoins. This view is inaccurate for two reasons:
1. The purpose of this whole computation power is to secure the Bitcoin transactions. The mined Bitcoins are "just" an incentive (i.e. a desired side effect).
2. In addition to the mined Bitcoins, the miners receive the transaction costs. In the future, the mined Bitcoins will become a lesser and lesser part of the incentive, gradually replaced by the transaction costs.
Luckily, this one seems to be an exception. Although the title is misleading, the process is stated mostly correct (except for not mentioning transaction fees). From the related article:
