That is just the gateway drug to bootstrapping.

you just probably want something better.

and that is the problem building higher performance requires more advanced lithography and that is expensive and until recently was not even an option for a hobbyist (without taking a mortgage on their house).

Given current stagnation, you need only wait about 10 years for that viable option.

I refuse to use a terminal emulator that needs more than 100MB of RAM to display 80x24 green text on a black display

checksums at the filesystem level does nothing to protect against memory corruption which can overwrite everything on your disk with null values and a matching checksum; fail to write anything to disk and/or do nothing.

But that is the gamble you take every day with every GB of RAM you have.

the correct answer is Gemini or gopher.

No ECC, absolutely worthless for a NAS if you care about your data.

Raid stopped being optimal now that btrfs and ZFS exist.

If you plan on doing matching drives ZFS is recommended

If you expect mismatched disks, btrfs will work.

If you are most worried about stability get a computer with ECC memory.

If you are most worried about performance, use SSD drives.

If you want a bunch of storage for cheap, use spinning disks (unless you exceed the 100TB capacity range)

The missing bit is social action, which no amount of software can solve.

So effectively light enough that it could run on a raspberry PI 4. Well that would put you under 10W

Well the first question is what software you NEED to run, then we can figure out hardware.

Your ZFS backup strategy should be to follow one of the following rulesets:

3-2-1 [3 copies of the data at 2 different locations for the 1 purpose of preserving the data]

4-3-2-1 [4 copies of the data at 3 different locations in 2 different types of media for the 1 purpose of preserving the data]

5-4-3-2-1 [5 copies of the data at 4 different locations across 3 different continents in 2 different types of media for the 1 purpose of preserving the data]

The details of the backup is more if you have a second system to enable ZFS send/receive or if you have to transport deltas from ZFS send

Tragically, you might be right about reduction in consumption being a cultural non-starter.

As it would make many things much easier but as you pointed out, advances in battery technology can fill some of that gap.

harmonization of grid standards is more than just frequency (it is mostly policy paperwork and the replacement of non-compliant equipment or the installation of conversion equipment) but you are correct high voltage DC is used for long distance power transmission. There are also details such as who is responsible for paying for what, where things are to be connected and various other bureaucratic details.

The big companies are ignoring the sector and just plan on buying the most profitable startups that look promising.

So ignore the fortune 1000 entirely and invest in smaller companies that are hiring engineers in chemistry if your goal is to invest effectively in battery technology.

But you are missing the advances in metallurgy (superconducting metals are making great strides), mechanical engineering (flywheel technology is taking advantage of new micro-controlled magnetic bearings) and physics.

Well a superconducting loop (even with liquid nitrogen costs/inefficiencies) would enable a global grid with quite minimal energy loses and reduce the amount of energy storage needed to sustain a stable grid even in the face of failures and disruptions.

The big problem tends to do with harmonization of energy grid standards.

well as you can buy solar panels at $0.50/W so a 10W panel can be obtained for $5 and a raspberry pi4 only uses 2.7W while idle and 6.4W when under full load.

Efficient is sexy

Sounds like they didn’t consider appealing to UK government to get subsidized liquid CO2 and use the produced hydrogen to synthetically create hydrocarbons (which are much easier/cheaper to store) and win political points doing so.

You are right in regards to very rural bus routes not being viable for electric buses but inside suburbs, cities and rural regions where the electric grid is already connected and in place, it is very cost effective to convert to pure electric.

But for rural bus routes away from a connected electrical grid, hydrogen is not a solution either as it is only 30% efficient (assuming only ideal conditions) and would be better served by liquid hydrocarbons. (I see no reason to deprive developing communities from the most efficient options)

I am in no way suggesting one would need to leave their family but one needs to understand up until the invention of the airplane, such relocation had to mean saying good bye and corresponding via mail or very rare train rides to visit with the whole family.

Green hydrogen outside of chemical processes (where it is actually useful) is a myth designed to keep the automotive industry alive past its expiration date.

The function of green hydrogen as an energy storage medium is better serviced by more custom chemistries as we are taking external energy to produce it (literally it would be the same as us taking CO2 + H2O + energy to produce gasoline [which we could do at the cost of $3.75/gal (if one ignores the CO2 collection costs)] using the Fischer-Tropsch process)

So skip the dream and accept the reality that if we are needing stored energy for transportation, it is more efficient to store it as liquid hydrocarbons. But if we need to store for transient demands, batteries and flywheels are better solutions.
