Yeah that's exactly what i do. I have an A record that points to my house and i update it every 4 hours from a script on my router. Been really happy with cloudflare, they have a weird restriction about using your own nameservers, but as long as you are happy with theirs then they seem to be great.

I was thinking about hooking one up to a GPS module to run a local NTP server

Also the argument we should be having in the US is whether we reach our climate goals through this kind of carbon-pricing model or the top-down regulatory model. In a sane world we'd probably expect republicans to be arguing for a carbon trading scheme and the democrats to be arguing for regulation.

They certainly should work at the power level. My utility is ~36% renewable in their power mix right now, but I pay for 100% and that extra money causes them to go out and buy extra renewables for the remaining 64% of my power. I'm not under any illusion that on a cold, still winter night that my power isn't coming from coal base load - but I have high confidence that they really are buying that extra power.

My employer does something similar, we buy the RECs from something like a third of the output of a local solar farm (under contract) and then also buy dirty power from the utility. That should ultimately wash out.

Though what I can't figure out is how that solar power is actually accounted for when it hits the grid. It's been severed from the renewable energy credits (that we bought) so presumably it must not count as a non-carbon power source when it enters the grid, but I can't find a category for "non-green solar power" on any of the utility reports. Anyone know where it goes?

That's right in the range for subfloor heating, obviously a question of whether or not you can get it somewhere that you need it

I suppose that's very true. But it could be done - if a data center needs megawatts of cooling and is in an area where buildings need to be heated in the winter, then there should be a legal obligation to not just dump that heat.

There's probably some alternate uses for the heat if these things were well designed. There's some building in denver that is near a major sewer and in the winter they use a heat exchanger to extract that energy and use it to heat the building.

Realistically they were almost certainly from a list of 69 remedies that spacex proposed to the FAA. I don't think the FAA is coming up with those items on their own.

I've seen it done in data center environments where there are two connections to two different switches - so you can do maintenance on either switch without downtime.

Same reason for having dual power feeds to each machine.
