The thing we do technically know how to do just haven't yet because there are no economic incentives to even tackle the finer engineering aspects let alone the regulatory approval ones, is to put a large vacuum-insulated (like a thermo

And the breaks notably may melt besides the landing gear suffering irreparable damage (to where you need to replace the landing gear). That's planned for and to be handled by the required fire fighting truck coming out and hosing them

Ehhh, it's surprisingly practical to pack a bit of a ship with batteries to get 3~5 days of range, at least for ships as efficient per unit mass an an Emma Maersk and above. What's less practical is the grid to support the fast ch

Modern trucks don't use cobalt batteries. LFP are better for that workload as they can be cycled much deeper (making up almost all the weight difference when just looking at nominal capacity) and are substantially safer and actually so

"take a while"? A quarter to a third of a conventional European long haul truck is fuel. And what unrealistic truck are you looking at? European long haul battery trucks currently have around 600 kWh of LFP; that's just aroun

Note the "I fear" is treated differently if you e.g. have to remove graffiti hate speech from your front door on a weekly basis. It's just about the "you better have a concrete reason to fear, pure abstract fear won&#x27

You don't; you let the second one pay more than what the marginal cost was, in order to make the first one not pay so disproportionally. That only has to happen once there is a second one, though. Punishing a mere "large enough to

3-phase electeode Boiler comes to mind. Just have it as a pass-through with a grounded shield at the end to keep you from accidentally touching dangerous voltage.

Only high speed trucks have a crew of drivers to rotate through to drive without more than a toilet break. Hydrogen is very expensive compared to just batteries. The weight savings only make up for the horrible efficiency of hydrogen once

I don't think it's necessarily impossible to get that billing model as a household; it's just not an interesting one to have as it's not competitive for the usage patterns of a household.

Actually the local cost is not the fuse size, but how much smaller the first transformer after you could be if you weren't there. Though it's often more fair to determine such for each user; then take those as a relative scale, th

It's legacy tactics; against the hacking the comparable thing for internet connections has historically been iirc 5 minute chunks and then taking the 95th percentile (like, charging not the highest, but the one 5% away from the highest

Both, currently; notably it's mostly not what goes to your local grid, but rather mostly to the larger scale grid. It's about a 60/40 to 70/30 split between production/"grid-usage-fee" ("Netznutzungse

If the area affected literally doesn't change for minutes afterwards it will not get refreshed and fixed.

What you could do is bill per energy in e.g. 15 minute chunks, and separately bill for transformer/line capacity by e.g. the peak usage in any such chunk over the contract period, like they do in Germany for atypical load profile indus

In a random German apartment usage tends to be on the order of 30-ish EUR per person, and the connection fee is typically around 10 EUR per month.

Grids in Germany if you're not a "typical household/office" with therefore atypical grid usage bill for peak power and energy separately; the billing related peak power is measured by averaging power over 15 minute chunk

Note that it's typically far easier to just teach the grid behavior aspects to anyways-existing battery interfaced AC/DC converters than to buy separate high power AC/AC converters, along with a flywheel and high power motor

That's kind of that ZNS is for: make the SSD dumb but in exchange predictable; let the database on top that already uses some type of CoW structure handle the quantization of erasure blocks; expose all overprovisioning from the start a

That was somewhat relevant for data centers years ago when inverters were much more expensive, and even then only for the 20 seconds it took to start the diesel by connecting a simple soft starter to the diesel's induction generator (b

You almost always want to see what's in the forced subs; but if you're reading a different language then it has to be translated first. Also compression and color/HDR mapping prefers the text be separate from the image.

Mumbai doesn't have issues of arguably too low density to split digging costs across enough users. It might have issues with the cost of digging, though. It's the "homestead in Maine" type of situation where the fiber pl

We know how to turn air into HDPE. It's just energetically stupid as long as we feed the electricity grid with fossil (hydro) carbon.

True DC grids avoid this stability issue by not having a phase and allowing power flow to pretty much just self-balance through voltage gradients and clipping of connections/devices to whatever current they can handle. With enough volt

Ehhh not really a problem unless you idolize 12/48 V style systems that aren't adequate for these modern chemistries (i.e., non-lead-acid based) that scale down effectively to single digit amp hours per cell. You can keep the cur
