*Technically*, this is very cool, impressive, and generally an elegant work of art. *Pragmatically*, I see 2 flaws in their thesis (as explained on the about page): >> "The entire network already consumes 10% of global electricity production with traffic doubling roughly every 2 years" I think the implication is electricity consumption will also double roughly every 2 years, but Moore's law actually operates on appro…

Check out the upcoming ATX power consumption and compare it to what we're using currently... What you said was true for a very long time, but Moore's law has slowed down a lot over the last 5yrs and power consumption has increased significantly, and is about to become unreasonable in my opinion. Maximum power draw of 2.4 kw for about to 10% of the uptime is ... sadly going to be reality soon.

> power consumption has increased significantly, and is about to become unreasonable in my opinion

It is not the first time it has happened, and then went down again. It's just one of the usual "cycles".

Small technical nit: I love the dithered images and the retro feel, but their CSS should specify `image-rendering: pixelated` to make sure browsers don't interpolate the pixels.

Wouldn't the correct css for the dithered image be `crisp-edges`? From the specification:

> The image must be scaled with an algorithm that preserves contrast and edges in the image, and which does not smooth colors or introduce blur to the image in the process. [...] This value is intended for pixel-art images, such as in browser games.

> This connection is a 100mbit consumer fiber connection with a static IP-adress. Yikes! And me here in Palo Alto, in the middle of the silicon Valley, cannot get any fiber because of AT&T.

It's hard to get even 100Mbit in Paulo Alto? Must be hard for everyone working remotely these days....

My AT&T DSL is blasting at 3 MBit/s down and 0.5 MBit/s up!

Digression: Is it true that every single watt my CPU/server/electronics consume is ultimately turned into heat? To put it another way, does a server under a constant 500W produce the exact same amount of heat as a dumb 500W electric space heater?

I'm sure you've heard the old joke about gamer college students using their fancy graphics cards to heat their rooms. :)

I feel like it's a very useful metaphor for the work ahead in dealing with energy production, consumption, storage, efficiency, etc. Layer 1: We must think of clever solutions to reduce our energy footprint where possible and shifting typical energy uses around is one way to do so Layer 2: But we must also be conscious and aware of economies of scale, and shifting the burden of energy usage from one central server to…

I'd rather avoid all these layers and just build so much nuclear we get to a future where electricity is too cheap to meter.

I did this last winter. Mining 24/7 on my personal rig noticeably took a bit of load off the heater and made a modest amount of ethereum. I stopped once the weather warmed as it seemed like a waste of energy.

Significantly, shifting the image calculations from the server to the client means the work is duplicated for every client. While it saves energy for the server, it increases the overall energy consumption required to deliver the content.

Apparently the mix-blend-mode for images on the client is noticable performance-wise: https://github.com/lowtechmag/solar/issues/6

In short, yes. Exactly (well minus a few used to spin fans and hard drives). Here's one source from a quick search: https://www.pugetsystems.com/labs/articles/Gaming-PC-vs-Spac... I remember seeing a paper referenced here once explaining why that energy loss is actually necessary, but I don't seem to have it saved anymore.

By a paper, do you mean the laws of thermodynamics?

The fans also eventually also dissipate their energy as heat when they push air around.

There is an alternative heater design though for the same power, which is a heat pump (the same as an AC, run in reverse), which can be much more efficient at heating (down to -5F outside, or so, when they may freeze over and stop working entirely)

a lot of the web would probably be better off if it were

I think so, WordPress that isnt cached to a frozen state on the backend is kind of silly in my eyes, the only exception would be comments, but you could hack around that by using Disqus or something, voila.

we had semi-static comments you are talking about. they were called guestbooks. but we gave up on them.

The only other places the energy could go are small - LED light, radio waves, sound. Almost all of it will go to heat.

And all of those things will go to heat eventually too, as will all other energy!
