For comparison, latest commercial turbofans approach 6000h (they don't have a strict TBO limit AFAIU, overhauls are decided based on various inspections and measurements). At a typical airliner speed that's something like 3,000,000 miles.
> IMHO, electric is going to revolutionize farming. Diesel is expensive (a lot more lately). And farmers burn a lot of it. Electric motors are small, reliable, quiet, etc. They have loads of torque. And if you are a farmer, you have plenty of space to harvest your own electricity with solar panels and maybe a wind mill and some batteries. There is a growing amount of high end stuff available in this space but also very affordable low end stuff. And this technology can be very simple and tinker friendly. Buy some old EV batteries wire them up and you can make anything with wheels move. Including really old tractors, pickup trucks, etc. Anything from the largest mining trucks to the smallest lawn mower can already be powered by batteries. And everything in between. With battery cost dropping, there are very few obstacles that prevent adoption left. Mostly import tariffs in the US.
Yes. But maybe not a 1:1 of current petroleum-powered equipment with an equivalent electric one? Say, crop dusting aircraft are not being replaced by electric powered crop dusting aircraft, but by (electric powered) crop dusting drones.
Could something similar happen for, say, tractors? A tractor is of course an extremely versatile tool, and as long as there's a human driving it there's a tendency towards ever bigger tractors in order to minimize labor/ha. But big tractors are already a bit too big and expensive for many not-huge farms, ground compaction is a problem with large weight etc. Could we see these replaced by a fleet of electrical drones (drones as in autonomous, not necessarily flying) rather than "just" an electrical tractor? Of course, there's a certain minimum power required to pull a plow etc., so maybe not? Of course, autonomous fleets etc. goes a bit against the idea of DIY-fixable. Or does it? A different skill-set than wrenching on an old tractor, sure.
The MNT Reform classic discussed here was designed 6 years ago, but there’s nothing preventing an updated motherboard with better port selection from being created.
The MNT Reform Next that’s scheduled to be fulfilled this year has a much more modern port layout:
Why not? It's only an adapter away if you have something thst needs to connect to a usb-c female host port. And if you need more ports, which seems likely, you can get a usb hub which has ports of your preference.
5 hours with LiFePo4 and 8 hours with Li-ion since the battery system in the Reform Next should support both chemistries you can choose battery longevity or longer runtime and more frequent battery replacements.
Mine does and it works so well that I actually have to turn it off when working from home as a bunch of the third party servers at work doesn't have any support for it.
That sounds more like broken support then. Not having any support at all (i.e. A records or v4 literals only) should just send you to whatever v4 transition technology your ISP offers, no?
They use 464XLAT, basically NAT64/DNS64 with some extra cooperation on the OS’s part for backwards compatibility with apps that hard-code IPv4. You get only a v6 address, and your OS basically synthesizes an v4 network on your device in cooperation with their NAT64 router. But all the bytes going from your device through to their towers are ipv6. Talking to a v4-only website uses carrier-grade NAT64 when leaving the t-mobile network.
Additionally, their fixed-wireless product gives you a physical CPE that does the CLAT (NAT46) side of the 464XLAT.
To the local network, it looks like there's native IPv4, but it's translated to IPv6 by the gateway, and sent to the "nearest" NAT64 PoP to be translated back and sent along its merry way.
My understanding the rail share of freight is relatively low in Japan compared to many other developed countries. Most freight moves by truck or coastal shipping. Looking at a map of Japan, most of the cities are by the coast, so I guess coastal shipping makes a lot of sense.
> China also has nationalized rail systems. The major reason for the failure in the US is that the rail lines are not publicly owned.
The article we're discussing explains that Japan has the best passenger rail system in the world, and which happens to be privatized, along with privately owned track. So which one is it? Go figure.
While I agree with you, their system did not start privatised, and the Shinkansens predate privatisation by some time. I don't have the evidence to justify this, but I suspect that you need national buy-in - both financially and politically - to start a HSR build-out, which could then potentially be privatised at a later stage.
I believe the Japanese private rail companies also own the lines where their traffic is. This would explain a lot. There are other countries (including my native one) where the trains are run by one company and the lines are owned by another. This does.not.work. For what seems like obvious reasons. There's no economic gain for the owner of the infrastructure to spend money, quite the opposite in fact.
The interesting thing is how the EU railway policy just keeps plowing ahead trying to impose the "vertical separation" approach in the EU, despite the disastrous results from the UK experience (and some EU countries to a somewhat lesser extent, so far the UK seems to be the only example of going all-in on that approach).
Most EU countries have adopted the approach of putting the infrastructure company and the public train company under the same holding company, which is sort-of the minimum that EU regulations demand. In practice, in many countries the previous national rail company (under whatever conglomerate structure it may be operating under today) is fiercely protective of its own turf and tries to prevent new entrants, and digging their heels in implementing EU railway competition regulations. So complying with the letter of the law, but does everything in its powers to not comply with the spirit.
Then again, given the UK experience of going all-in on the "vertical separation" and privatization path, perhaps one shouldn't blame them.
Calling Japan Rail privatized is a "ehhh, kinda, in some places, if you squint" kinda thing.
Technically, yes, the JR's are private companies.
But track construction is generally done by a government construction company financed with Japanese sovereign debt. The completed tracks are then long-term leased to the JR's at favorable rates.
Is it really a private company if the key capital outlay is done by the government and given to you with a sweetheart deal? ehhhhhh.... you can call the operator company private, but you're being dishonest if you call the system privatized.
Some years ago I tried to learn CAD by doing some FreeCAD tutorials, and failed. But I hear 1.0 was a big step forward, and the recently released 1.1 is also a big step, and it should be somewhat decent nowadays. Maybe I need to try again one day.
Yeah it's vastly better in 1.0 than it used to be. I still think you might be a bit lost if you aren't familiar with parametric CAD, but it's no harder than Blender for example.
