We already have that in the form of fission. The problem is our societal lack of interest in fission.

I think the bigger issue is that LCDM has no produced much fruit in the last several years. Despite many attempts to detect it, no one has found anything. Furthermore, the main motivation for LCDM was super-symmetry, but the latter has also

Agreed. They're companies trying to avoid taxes or regulation. Only companies on the downslide really consider that as an relevant option.

But a valid one. Sadly, people don't like to hear this at all. I'm going to go ahead and say Tesla is in the same boat as Oracle or HP, as a company where its biggest innovations are in its past. It will likely join Oracle in movi

There's still no support for Apple Carplay or Android Auto in any Tesla. So I very much doubt they're part of the tech ecosystem.

The people making the ads are only responding to what their bosses want them to do. If the latter have no clue, the ads will be equally clueless. Plus, the Presidential Limo is just a truck platform with a Cadillac logo on it. I'm sure

Yeah, they're totally lost and are constantly trying to reinvent the brand. It's hard to see this level of cluelessness and not realize that the brand is likely doomed. For some reason others don't like that interpretation of

Porsche is investing in e-Fuels. The internal combustion engine might not be totally dead. Plus, the EV of the future could be powered by fuel cells, not batteries. The problem with Cadillac is that GM tries to reinvent it every few years.

That was in the 1990s. Not to mention they were trying to build a non-cylindrical tank which made things significantly harder.

Carbon fiber? That's what cars like the Toyota Mirai are storing it in.

This is close to becoming a FUD argument. Hydrogen does not leak out of properly designed pipes and containers in appreciable quantities. Embrittlement doesn't not happen either except for specific cases or where an incorrect alloy was

That viewpoint is comically out of date. It's unaware of 10,000 psi carbon fiber tanks for one thing. There are many other things wrong with it.

Conductive metals have resistance, so they must lose a portion of their energy as heat. A pipeline only has to overcome friction on the inner surface of the pipe, which is easily reduced by having a wider pipe. So this isn't a surprise

It's going to be both: It's not cheap to convert a ship to fuel cell power, so in the short-term a lot of them will just burn ammonia as a fuel. Longer-term, converting ammonia into H2 and N2 will be the more common strategy.

We're nowhere near the point where we can't feed the population using existing agriculture land. We're a very long ways off from needing solutions like vertical farming.

It's plainly a fraudulent product given it's naming and marketing. It's a shame people choose not just to believe in it but also defend this behavior.

Which is why the Hummer EV is a terrible idea. If excess is the point, then it should be banned or heavily discouraged. There's no point in having such a vehicle around.

The central point of proper accounting is that it prevents frauds, scams, Ponzi schemes, or other nonsensical companies from existing. Companies that feel free to abandon those principles are inviting the possibility of becoming one of thos

Which is the problem here. A Hummer EV is as impractical as the original Hummer.

A normal sedan would get around 35 mpg. If you pay more than $0.15/kWh, a Hummer EV would be the more expensive vehicle to drive. This figure gets worse if you compare it to a hybrid sedan that can reach 50 mpg.

For a vehicle of this size, that might be only 60 miles or so. It's possible to drive normally and still find yourself short on charge every night. A 48A circuit is probably required for acceptable charging times. Plus it would be legi

At 200 kWh this might not be possible. Depending on your charging speed, you might not be able to fully recharge in one night.

A long running problem with Tesla. Their accounting has always smelled, and this has only gotten worse with every passing quarter.

Your process still requires an electrolysis step. It's basically claiming that they can extract CO2 alongside the hydrogen, allowing for either the Sabatier or Fischer-Tropsch process to make hydrocarbons in a relatively cost effective

You're weight limited with large trucks. Anything adds more weight will just take away from your cargo capacity. Not to mention the complex and logistics of having hundreds of thousands of battery trailers. This is really just wishful

While it's possible to exceeding 100% efficiency with an SOEC, you will need an external source of heat to drive the process.

If you live in California you can just go to a dealership and buy a fuel cell car.
