Not an expert, but if it was a purely deregulated market, wouldn't you expect the cheapest supplier to win? The power grid is a shared medium, and you get a "tragedy of the commons" situation. Everyone profits from a resilien

The main thing about homo sapiens is that we are a cultural species, capable of evolving and select for culture much faster than genetic evolution, passing know-how and tools down to the next generation to improve. The culture, tools and va

Oh please. It's bad hook, yes. But once we get over that, we should acknowledge that this is an extremely well-written article. It has been a long time since I've stumbled over an article on HN that was such a joy to read.

All general statements are false. Joking aside, you can sometimes prove causality. It's just not as easy as proving a correlation. The most broadly accepted method would be a RCT (randomized controlled trial), though it is often unethi

A steady current would also produce a rush of water, but I don't think you can get EM radiation with just a steady current. Well, but maybe... if you equalize two water tanks with a very fat pipe it will swap forth and back, causing th

I don't think the water analogy is a good fit here. For me the revelation was that energy can also be radiated away. When we did basic circuit exercises we never talked about that. Energy was either stored or turned into heat. Not sur

by Matumio 6y ago
From a grid-optimization point of view a hot water storage is almost as good as a battery. You can "charge" it whenever unreliable local energy sources (wind, the solar panel on your roof) are producing in excess. This helps to c

No, but good luck trying to burn some piece of forest to get your piece of earth for your farm. You cannot justify the existing order with basic human needs. In some places you even have to pay for access to water.

Right, I always open news front pages from a bookmark for some reason, and stories as background tabs. Each tab has its own delay-block when activated, and at some point I usually close unread tabs instead of waiting for them. But the block

LeechBlock NG (the browser extension) has a "delay" mode of blocking. Make sure you enable "count only active tab" or it will waste much RAM and CPU. With full blocking I used to cheat by disabling the block, and then &q

If you're running some form of ntp, the underlying hardware doesn't matter that much. An offset greater than 0.5s is probably caused by ntp not running, time jumps during hibernation, automatic VM live migrations, or other virtual

Is there really a way to "use" energy for computation that doesn't just convert all of it to heat?
294.
by Matumio 7y ago
But there are some pretty cool applications. Apparently the heat difference between a buried water-pipe and the surrounding earth is already enough to power a wireless sensor, which can transmit data to localize leaks, for example.

Surely we have historical data to validate models with?! I'm no expert, but this all sounds very plausible to me. Some parts are even basic physics, like reflection and black-body radiation, which I'm pretty sure we have nailed do

Good points. But it should be mentioned that, once you have your logic working in an FPGA, the additional step to make it ready for silicon is comparatively small. So I don't think it's too bad to confound the two.
