Electric buses in the form of trolleybuses seems like the better option than either of these, although I do agree that battery buses beat hydrogen every day of the week.
Batteries are cheap. Installing lots of copper lines for trolley buses isn't. That's why trolley buses are pretty rare. Old idea, didn't really take that well. There are a handful of cities that have them. And they've had them for decades. Most of those cities now also have battery electrical buses to service all the areas where the cables don't go. Expanding the network of cables doesn't seem to have a very high priority. Installing chargers (in depots mostly) is much easier and cheaper. And it's not like batteries are that expensive.
With battery prices trending to 50$ per kwh, a decent size bus battery of 250kwh would cost about 12.5K. That's manufacturing cost, not purchase cost. But it drives the point home: long term batteries are going to dip even further. Far below 50$/kwh. It will drive down the cost of battery electric drive trains for everything with wheels to far below that of the traditional setup with ICE engines. And they don't need expensive fuel to run. Or a lot of engine maintenance and servicing.
Currently tens of thousands of electrical buses are produced per year. Most of them in China. Which is of course where they have lots of battery factories. It's a rapidly growing industry.
Yep, hybrid trolleys / battery trolleys are really cool, as they provide the flexibility of batteries to e.g. work around roadworks and blockage, but allow for a more distributed electricity consumption thanks to partially fixed routes / overhead lines.
The poles also make for convenient overhead charging docks, which you can add on a somewhat piecemeal manner. With some automated guidance, that means you can charge the buses at long-wait stops or when they wait to run the route back even though they're not a a depot, without the need for an "accessible" charging infrastructure (or the driver needing to move out, go open an electric cabinet, plug in a charge cable, then remember to unplug before going back out).
Trolly wires generally work out cheaper than batteries if you are running frequent service. Batteries work out better anyway though because they allow you to go around obsticals (roadwork, cars illegally parked in the land...)
My experience is that anyone who is sufficiently specialized in either platform will select to develop natively for that platform over using RN, since RN imposes lowest common denominator UX for both platforms, more or less.
I'd be curious to see numbers on this. Currently I believe you, although as EV adoption expands and EVs get cheaper I'd expect to see more people who can't charge at home buy them and charge at work/stores.
Also I don't have an EV, but if I did charge it equivalently to how I use my gas powered car, 1 trip to where I needed to recharge outside of the house would likely be equivalent to about 80 days of home charging.
Maybe I'm not understanding your point, but here is my math. 80 days * 24 hour/day * 1.4 kW (L1 charging / 12A @ 120V) = 2688 kwh of electrical energy. If your EV has an efficiency of 3.5 miles/kWh, that 2688 kWh would let you drive 9,400 miles. Of course, if you had a 240V @ 40A L2 charger at home, that would be 18,400 kWh, or 64,500 miles (@ 3.5 miles/kWh).
I think this is currently right but a view heavily based on freestanding houses with garage or carport that can charge there.
The whole apartment or city charging is still developing. At least in Australia.
I agree, but these are broadly the categories of people most in need of cars. The density provided by apartments often affords less inefficient modes of transport, like transit.
In many places in the world, this ideal falls short however, and hence a push for installing EV chargers in apartment garages is also needed.
No countries readily jail people who have the legal right to enter that country as the U.S is currently doing, but if you wish, a reciprocal policy for U.S citizens traveling abroad can certainly be arranged.
Having a visa doesn't give you the right to enter. I don't think permanent residency does either.
It's always at the discretion of the immigration officer and there's no recourse if they don't let you in.
Personally, I don't think it's generally reasonable to jail at entry when denying entry is an option. The case where the UK tourist was denied entry to Canada from the US and then was jailed in the US is a case where denying entry isn't really possible, because if neither side of a land border will allow entry, what do uou do... but then it shouldn't have taken more than a couple days to make arrangements for her to fly home on her own dime.
False. But what would it matter if the people have not prospered alongside. I am not the USA. I am a person who writes software and likely has made half of what I would from a lot of hard work, due to competition that other countries have done a better job of keeping out for their own people.
And now with AI eliminating most programming jobs, which will happen by the way, that downward pressure on wages may mean I'm finishing up my career starting over in a new one within 5 years.
Pure stolen wealth, essentially even stolen lives from hard working Americans. We are people who studied hard, we worked hard, we played by the rules. And our lives were stolen from us. Our retribution starts now.
I'm not sure I'm entirely on board with this particular format, but I do agree with the larger point of well-crafted commit messages - and commits, for that matter - being an important quality feature in a project.
I'd posit that well-structured commits are principally for the benefit of the reviewer of the code. Order your commits in a fashion that makes sense narratively, and give them meaningful commit messages. Use interactive rebasing liberally if need be to accomplish this goal.
As a reviewer, you are well within your rights to decline a PR that consists of a single non-meaningful commit message and a +/- 1000 lines diff. Effort is expected from both parties in checking in code.
And the best part is, if you ever need to fill out a PR template with what you did or list the changes, it becomes so much easier. You don’t even have to remember exactly what was changed, it’s all right there in the commit message.
>They’ve stolen unimaginable amounts of IP and will continue to do so.
All AI models are built on the back of massive amounts of "IP stealing". Either we consider IP to be valid and then all western companies in this space are just as bad, or we go with the direction the western companies are claiming and then China is not doing anything wrong.
