Most of the ones run here don’t have batteries. It is running on wires only - with battery trolley bus you need bit different wires so you can put the “antenna” up and down when needed. And since the network was built in 50s it didn’t made sense to buy the partial ones until few years ago.
But I get the appeal of the ebus it just sounds cheaper. One city I won’t name started to build trolley bus network again after they got rid of it in 70’s (because of metro construction and expansion of trams), but they just doing it bit idiotically by wanting to have like 30% of it on wires and rest run on batteries.
Why? Because the infrastructure is just more expensive upfront.
Will it work? Nobody knows, people that are building it lobby to get it up to at least 50/50 then it is maybe just feasible.
I think that roads and buses have place in the transportation but you just need more options not just that.
I am for electrification but I just can’t get behind electric buses.
My city made some study last year and the best way forward in terms of public transport is expansion of trolley bus network. With batteries and constant use it just doesn’t make much economic sense. If you can build the wiring it is much better in long run. You don’t have to have 100% coverage, 70+% is enough for partial battery powered trolley bus, then it starts to be economically feasible in the operating cost sense.
Also they will need to build some kind of metro system - probably as an extension of commuter trains.
I would guess that it may already started to deflate a bit. The truth is that it will pop when the loans won’t be paid off so investors and banks starts to backtrack.
I am not worried about Nvidia but cloud providers. The datacenters built to support ai won’t have much use when the customers (OpenAI…) will fold.
I don’t care about what happens with OpenAI and other AI startups they probably don’t survive. Google, Microsoft, Meta… have enough money to lose so it will be bad for them but they will survive it. Hardware manufacturers see the writing on the wall and try to milk the bubble till it lasts so if they play it decently it won’t be big issue for them - they are probably the winners in this race whatever happens.
