Yeah, sending 48V would be more appropriate, but unfortunately that's not really backwards-compatible (well, the way to do that is typically to allow the PSU to be farther from the use-site, like having a datacenter with tall adult hi

There's actually an EU standard for using the smartcard functionalities of the ID cards to provide strong authentication/KYC-grade auth. EIDAS, iirc.

Where did you get the existence of sub-km (horizontal) grid forecasts from? Thus page https://www.dwd.de/EN/research/weatherforecasting/num_modell... contains the following sentence: "The operational NWP

On part that's what ensembles are about: they run like 20 or so simulations of the near future, randomizing the start values and simulation parameters within the range of uncertainty, and get one potential future per simulation out of

No, the source is the waste water, the target is the fresh water. You could either use a heat pump to move the heat from the colder waste water to the hotter fresh water, or use a direct heat exchanger to pre-heat the freshwater while chill

Well, outdoor temperature determines the heat load demanded of the radiators, and lower exhaust temperatures for a condensing boiler mean more condensing takes place. So unless/until the circulation pump starts to dominate, one wants t

Non-superconducting electrical transmission lines don't want to be buried, it's really expensive and harder to handle/deal with when stuff breaks. You also can't have forest on top of it. One can hope we get by with the

You can use the NaOH/CaO cycle to scrub carbon dioxide at atmospheric conditions and even regenerate the calcium carbonate with a (fairly cheap) methane + pure oxygen lime kiln (electric lime kilns are currently in testing). I'm f

I'm not sure about how bad/dangerous the failure modes are (relative to the anhydrous NH₃), but cryogenic O₂ stores quite easily and the purified O₂ should come out of the (solar-powered) production of NH₃, some even already as a

You don't even need to purify N₂ that much, as you can just add air to H₂ and feed that to the reactor, wasting some H₂ on O₂ but AFAIK it's quite cheap to enrich air to low-purity N₂ via pressure-swing adsorption, and it's j

The gun is less about anti-disappearance, and more about getting permissions for a proper lock where the key bitting isn't available for ~10 bucks in a ring of ~5 keys.

That doesn't rule out DKIM, which only requires the `From:` header's domain to list a pubkey and the email to include a DKIM signature from a matching private key. SPF is the one that regulates which hosts a domain's outbound

Yeah, but indirect (with e.g. water/glycol between the condenser and the indoor air handler) systems can be combined with scrubber tanks (basically just water+baffles, I think) that the blow-off from a leak or a pressure relief valve i
