Don't forget Waterfox too.

That's the point. That he's barely remembered at all.

Wrong. The average person barely knows who he is now. He used to be praised as this great individual.

We will only remember Ford as being a racist anti-semite in due time. Edison got the same treatment. So will Musk.

We will eventually remember Ford for being a fascist and stop caring about everything else he did. Something similar already happened to Edison.

Long duration energy storage is necessary for a purely renewable grid.

Hydrogen is not a GHG.

They should just post-pone the PS6.

It needs to run on non-AMD hardware too.

You can also turn water + atmosphere into synthetic fuels, such as methanol or even kerosene. Such fuels can be used without modification to existing ships. Alternatively, you can just electrolyze water and get hydrogen, which can also be used if you can deal with the lower volumetric density.

The problems are mostly solved already. You wouldn't use metals known for hydrogen embrittlement. Often times, you'd use something else, like HDPE or fiberglass that avoids this issue. Storage facilities can even be naturally occurring geological features, like salt caverns.

You would only use LH2 for specific cases, specifically where you are expected to use up the hydrogen quickly. But even this is changing, as self-refrigerating systems are being developed, allowing for very long-term LH2 storage.

We already can make hydrogen via electrolysis. This is a long-solved problem. Efficiency is not that relevant. The main limitation of batteries is that you simply cannot make enough of them. There are huge resource limitation problems. Meanwhile, hydrogen can be made from water and is effectively unlimited as a resource.

You can't store electricity by itself. The problem we are facing is massive curtailment, i.e. massive overproduction of green energy that can't be utilized. There needs to be way of storing it at a massive scale. There is no feasible way of storing that much energy in conventional batteries.

If you can acknowledge that hydrogen is needed for dense energy storage and grid-level storage, then you should realize that we will eventually have a huge hydrogen infrastructure, and production capacity to match. That will create very cheap green hydrogen, and will mirror what happened with solar and wind.

Cheap hydrogen alone will drive large-scale adoption of hydrogen cars, regardless of the popularity of BEVs. A lot of people will choose hydrogen cars (possible e-fuel cars too, since e-fuels can be made from hydrogen) simply because it is akin to an ICE-car in usage.

The other point is that battery production is not green and is very resource intensive. Hydrogen cars let's you avoid that almost entirely. In the long-run, it will be pointless to care about efficiency when green energy becomes nearly free. That suggests hydrogen, not batteries, is the better idea.
