Any GTAM'ers own an electric vehicle?

Tariffs will continue to ensure a level playing field. Already in place at 100%.

Chinese car manufacturers are operating on an unfair playing field, being basically subsidized by the Chinese government. If we did the same and dumped underpriced cars on *their* markets in an effort to corner them, they'd do the same.

The Chinese government has dumped about a quarter trillion dollars into the chinese EV market, throwing money at anyone who wanted it (including Tesla) to develop their market and pump out product, and unsurprisingly, along with dirt cheap labour (the average autoworker makes only a little over $2K Canadian equivalent in a month), this gives them an unfair advantage.

Seeing Tesla rush to suck at this teat in Shanghai, building their Gigafactory on the backs of CCP money only to now get the cars they're pumping out there on the cheap tariffed all to heck when they ship them back here to sell at a gross profit is a bit heartwarming.

Any thoughts about using something like the Juicebox?

Don't do it. They just bailed and essentially bricked everything on the way out. Home chargers will still work as dumb chargers, all brains and remote access are removed. Commercial chargers are fully dead.

JuiceBox Abruptly Shuts Down, Abandons EV Customers

A popular home charging hardware company announces the Oct. 11 closure of its US and Canadian businesses, with no continued tech support.

Yeah, the Juicebox thing is just a dirty, dirty move on their behalf.

At least open source the firmware on the way out the door so someone could write something to give them purpose moving forward beyond being a dumb charger. Just plain bricking the commercial chargers is also another level of douchebaggery.
 
Aside from owning a giant turd, now Cybertruck owners are apparently being un-insured by their insurance companies because they're quickly discovering that, well, they're giant turds that cost eleventy thousand dollars to repair in even a minor accident, and are demonstrating daily that they are of questionable quality and safety.

I like it.
 
Partner warming up to BYD..I think the Sealion 6 is the perfect vehicle for her.
$48k plug in hybrid with 92km EV range and can be used as a battery for the house.
One thing that appeals to me is with an extended hurricane power out - running a hybrid might be better than a pure EV as we can run the ICE motor to recharge the battery.
She doesn't like the interior. :rolleyes:
Limited colours....well she admits she would buy white anyways

There is a dealer in Cairns offering test drives. What I don't know is if they take trade ins.
The 4 year old Honda CRV is likely still good trade value.
If my tooth feels okay I might swing by on the bike and ask questions and get a test drive.🍿
 
Minor digging finds something from a couple of years ago that each cartridge is 400mm long and 180mm diameter, and the target weight was 5 kg; whether they've achieved that or not ... unknown. I can't find how much volume (i.e. weight) of hydrogen is contained in each one, but I did find "When electricity is generated by a typical FC system, one hydrogen cartridge is assumed to generate enough electricity to operate a typical household microwave for approximately 3-4 hours (based on the assumption of using a future iteration, high-pressure hydrogen tank with an electricity output of approximately 3.3 kWh/unit.)." Toyota and Woven Planet develop new portable hydrogen cartridge prototype to power everyday applications - Toyota Media Site

Hmmm ...

Hydrogen at 700 bar pressure (I have no idea if that's what they're designing for, but it's become pretty standard) has a density of 39.6 grams per litre, call it 40 g/L. A cylinder of the dimensions above has a volume of 10 litres based on the outside dimensions and you have to subtract from this the volume of the cylinder walls (which will be significant). So ... 400 grams of hydrogen maximum. You would need about 12 of these cylinders to equal the contained hydrogen volume in a Toyota Mirai. And 12 of them would have a capacity of about 40 kWh based on what's stated in the above link. I'm thinking the contained hydrogen volume is rather less than this (due to wall thickness, rounded corners, etc). You would need 18 of them to match the battery capacity of my Chevy Bolt. 18 of them x 5 kg = 90 kg; this is less weight than the battery in the Bolt but we haven't included the weight of the fuel cells and their supporting hardware AND the (smaller) battery pack that a fuel-cell vehicle still needs.

Laid out transversely 2 wide x 9 the length of the vehicle x 1 thick gives "pack" dimensions of 800mm across the width of the car and 1.6 metres along the length of the car, plus something for clearances and crash structures and the like. This is in the same ballpark as the dimensions of a lithium-ion battery of the same capacity (it's a little smaller but you still need "a" lithium-ion battery in a fuel-cell vehicle - just smaller).

So do you want to "refuel" by hand-bombing 18 of these 5 kg containers into wherever they're stored in the vehicle every 400 km ... or just plug the darn thing in?

I can see the use case for camping and so forth, to replace propane-fuelled cooking or generators. Maybe there's a use case for urban scooters and the like, which could make do with a couple of those containers to have 6.6 kWh of equivalent capacity (but fuel cells and so forth will make for a mighty complex and expensive scooter).

Does liquid hydrogen suffer any issues with gassification in the cold?

I have a few butane cook stoves that we bring camping that I use for cooking outside at the picnic table. I do know that once the ambient temps get much below 10c they start to lose flame power, and much below 5 the flame all but goes out. You have to flip up the side cover and put your hand on the cylinder and it leaps back to life.

Reading all the stories of Wankpanzer owners with endless problems and other various nightmares is pretty hilarious.

Can you imagine if one of the Big3 released a $100,000+++ truck that was basically the HomerMobile?

Anyhow, all my Volts parts are still attached.

You have to admit, they are persistent in doubling down on hydrogen. Every "innovation" they come out with increases cost.

have to admit, even I thought they were crazy, but never underestimate the Japanese. they are crafty and incredibly intuitive for the most part..........while the whole world was preaching and dumping Billions (with a B) in to the EV "revolution", Toyota (and Honda). were criticized for not joining and being "left behind". With the result of the Big 3 and others now rolling back their EV plans.

whose laughing now?

As I said in Post 2 years ago, "EVs are here to stay" and hybrids are the way to go.

Notice how Honda is readying a plethora of EVs by 2030. By then EV adoption should be far more ripe than it is today for wide scale adoption , and they will be ready to capitalize. Smart, very smart.

I still think hydrogen has a future, let our Japanese friends continue to invest and innovate in their calculated approach, they aren't pushing it down our throats, rather they continue to quietly invest, learn and innovate as they go along.

Hydrogen isn't practical to store as a liquid for end-user applications. (You would have a choice between continuously-operating cryogenic refrigeration apparatus - $$$ and constant energy use - or accept slow evaporation along with having a place for the evaporated hydrogen to go that won't cause an explosion.) The most practical way to store hydrogen for anything more than short-term use is as a pressurised gas (700 bar pressure). If the temperature drops from 27 C (300 K) to -3 C (270 K) then the pressure would drop to 630 bar (ideal gas law) ... still much more than any appliance would want, so it still has to go through a pressure regulator to drop the pressure to something that the downstream appliance (whatever it may be) can use.

An interesting oddity of hydrogen is that due to its low mass, the temperature goes UP when it expands through a flow restriction. The mechanical energy from the pressure gets converted to heat. That happens with all gases, but for gases other than hydrogen (maybe helium, not sure), the temperature drop due to expansion is more than the temperature increase due to the conversion of mechanical energy to heat. Hydrogen is so light that the temperature increase from the mechanical-energy losses is greater than the temperature drop due to expansion.
