list of entry level questions:
Giga Casting is like....3D printing a huge part and snapping them together like gunpla?
solid state batteries seem like a big deal: why is it a difficult technical hurdle, if no other competitors are doing it? The main benefit is more durable battery?
the toyota crown shown in the pdf looks a lot like my 90's era corolla....related model?
Okay I'm picturing a bubcha folks sitting around a factory using game pads to control giant robot hands to snap pieces of car butts off giant runners now. Thanks for the video link!

Im glad to see Toyota is pressing ahead with hydrogen fuel cell technology especially for medium and heavy duty trucks. There are many fanboys in my local EV group who have openly mocked Toyota for being "behind" for not fully jumping on the BEV bandwagon and abandoning any other tech as inferior. On the other hand, I live in the middle of oil and gas country and many here are hoping that the use of hydrogen will keep the industry going well into the future even if oil and gas production is slowly forced to decline. To me, it makes a lot more sense to put fuel cells on a heavy vehicles, especially a long haul semi, then to try and cram another couple of tons of batteries into the chassis. Not every truck stop is going to have a nuclear reactor to charge 300 semis overnight.
Plus truckers get pretty cranky if a driver leaves their truck at the pumps for more than a few minutes after they're done fueling. If they had to wait an hour for a charger to open up, there...
Plus truckers get pretty cranky if a driver leaves their truck at the pumps for more than a few minutes after they're done fueling. If they had to wait an hour for a charger to open up, there would literally be gun fights in the truck lot. They get paid by the mile, not the hour, so a wasted hour is literally taking money out of their pockets.
This is part of the concern with the environmental crowd. The oil and gas companies/lobbies are pushing hard for some type of hydrogen for exactly this purpose, and while it may be cleaner than...

“There may be some small role in truly green hydrogen in a decarbonised future, but this is largely a marketing creation by the oil and gas industry that has been hugely overhyped,” said Robert Howarth, professor of ecology and environmental biology at Cornell University
I definitely understand this perspective, and if these types of dirty hydrogen were relegated to the above mentioned industries and vehicles it wouldn’t be such a worry. But we both know how it...
I definitely understand this perspective, and if these types of dirty hydrogen were relegated to the above mentioned industries and vehicles it wouldn’t be such a worry. But we both know how it will work out in practice, with the oil and gas industry pushing for it to be used in consumer level vehicles.
Governments only have so much budget for investments and incentives to fight climate change. Societies have hard decisions to make, and that includes bowing to oil and gas companies or spending more money investing in greener alternatives, of which are further along in their development.
Hydrogen won’t be going anywhere as we’ll need it for a long time as rocket fuel and we should absolutely explore options for actually green hydrogen. I just think that’s a longer way off than BEV solutions for more vehicles, which will probably include everything right up to aircraft as the technology improves.
I also think hydrogen makes sense by virtue of being a solution that exists. The problem is that if it doesn't solve the problem (I.e. if most hydrogen comes from steam-reforming methane), it can...
I also think hydrogen makes sense by virtue of being a solution that exists. The problem is that if it doesn't solve the problem (I.e. if most hydrogen comes from steam-reforming methane), it can be worse than simply saying "we don't have a sustainable way of doing this, so please just do as little as possible." For example, cargo shipping between China and Germany could be replaced by electrified trains, but hydrogen shipping would discourage that.
I am by no means an expert in these fields; but if this is where all car production goes, doesn't this tether us back to "fuel" style companies? Shell, BP and the like are going to be essentially...

Shell, BP and the like are going to be essentially redundant if EVs become the norm. The average Joe can get solar on their home and slow charge their vehicles with minimal additional cost.
I could easily be wrong; but if I were a fossil fuel company, I would be pushing car manufacturers to build and research types of cars that I could continue to profit off.
True. But solar powered doesnt necessarily mean that the solar panels are on their home. They CAN work on their vehicle. There have been a couple of attempts so far, one of which, Lightyear in...
True. But solar powered doesnt necessarily mean that the solar panels are on their home. They CAN work on their vehicle. There have been a couple of attempts so far, one of which, Lightyear in Europe, seems to have just gone under. But there's still hope for Aptera, a US company with a very unique, lightweight, relatively inexpensive vehicle that can have up to 1000 mile range on battery, but more importantly, can charge and use up to 40 miles a day just from the solar panels that cover the car. They've made great progress but funding, as always, is the issue that may delay production even longer. Aptera.us
Aptera has some strong points - hyper efficiency with the lowest drag coefficient of any EV by far, a body with only 4 main pieces making for simple assembly, in wheel motors meaning less drivetrain parts and simpler assembly, and a full right to repair for owners.
I guess I should have clarified that I was talking about the environment over here in Australia. Almost every new home built here has solar and we have plenty of government incentives to have it...

Casting is how you make ice cubes in your freezer. Industrial casting is usually done with molten metal, though.

Batteries also really suck for aircraft.
This is part of the concern with the environmental crowd. The oil and gas companies/lobbies are pushing hard for some type of hydrogen for exactly this purpose, and while it may be cleaner than oil, it's still a lot dirtier than alternatives.
There may indeed be a place for it in some heavier vehicles, but the infrastructure required isn't exactly cheap itself either and can be dangerous.
